1 00:00:00,320 --> 00:00:02,880 Speaker 1: Brought to you by the reinvented two thousand twelve camera. 2 00:00:03,200 --> 00:00:09,000 Speaker 1: It's ready. Are you get in touch with technology? With 3 00:00:09,039 --> 00:00:17,880 Speaker 1: tech Stuff from how stuff works dot com. Hello again, everyone, 4 00:00:17,880 --> 00:00:20,919 Speaker 1: and welcome to tech stuff. My name is Chris Polette 5 00:00:20,920 --> 00:00:23,200 Speaker 1: and I am an editor at how stuff works dot com. 6 00:00:23,239 --> 00:00:26,440 Speaker 1: Sitting across from me, as usual, is senior writer Jonathan Strickland, 7 00:00:26,600 --> 00:00:31,360 Speaker 1: and Leon is getting larger. You've been threatening to do 8 00:00:31,400 --> 00:00:33,040 Speaker 1: that for a while, I haven't you, Yes, I have. 9 00:00:34,159 --> 00:00:37,120 Speaker 1: So today's episode comes to us courtesy of a little 10 00:00:37,800 --> 00:00:44,720 Speaker 1: listener mail. Let's listen to. Mail comes from John, and 11 00:00:44,840 --> 00:00:47,800 Speaker 1: John says, how are you guys? I hope this email 12 00:00:47,840 --> 00:00:50,000 Speaker 1: goes through. I didn't see a contact email on your 13 00:00:50,000 --> 00:00:51,760 Speaker 1: web page, but I always hear you announced it at 14 00:00:51,760 --> 00:00:55,320 Speaker 1: the end of your podcasts. It got through. John. First 15 00:00:55,320 --> 00:00:57,680 Speaker 1: of all, I love listening to your podcast. You guys 16 00:00:57,680 --> 00:01:00,320 Speaker 1: are great and the subjects you discussed are also. Keep 17 00:01:00,400 --> 00:01:02,680 Speaker 1: up the good work. My question is in regards to 18 00:01:02,720 --> 00:01:05,840 Speaker 1: Google maps traffic overlay. I usually check it before I 19 00:01:05,920 --> 00:01:07,640 Speaker 1: leave from work in case I have to take an 20 00:01:07,640 --> 00:01:10,280 Speaker 1: alternate route due to a traffic problem. I'm wondering how 21 00:01:10,319 --> 00:01:12,600 Speaker 1: Google can display how the relative speed is of a 22 00:01:12,600 --> 00:01:15,920 Speaker 1: particular stretch of highway or road. Do they use cameras? 23 00:01:15,920 --> 00:01:18,400 Speaker 1: Do they measure cell towers handing off phones? Do they 24 00:01:18,400 --> 00:01:20,760 Speaker 1: rely on people calling in? Google seems to have a 25 00:01:20,760 --> 00:01:22,880 Speaker 1: lot of public information gathered in one place, but I 26 00:01:22,880 --> 00:01:25,280 Speaker 1: don't know how they got their real time traffic data. 27 00:01:25,640 --> 00:01:27,680 Speaker 1: If you've already done an article or podcast on this 28 00:01:27,760 --> 00:01:29,880 Speaker 1: that I've missed, just please direct me in the right direction. 29 00:01:30,160 --> 00:01:31,959 Speaker 1: It'd be great to hear an answer on the podcast. 30 00:01:31,959 --> 00:01:34,560 Speaker 1: Of course, I am really interested in the answer, So 31 00:01:34,680 --> 00:01:36,760 Speaker 1: any way you can help would be appreciated. Keep up 32 00:01:36,760 --> 00:01:41,399 Speaker 1: the great work, John. Thanks John, you want to You 33 00:01:41,400 --> 00:01:44,200 Speaker 1: want to know the fascinating thing about that, John, is 34 00:01:44,480 --> 00:01:48,640 Speaker 1: they're getting it from you. Yes. Um, Actually, if you're 35 00:01:48,720 --> 00:01:51,440 Speaker 1: using a any kind of if you're using any kind 36 00:01:51,480 --> 00:01:53,880 Speaker 1: of cell phone that happens to have a GPS receiver 37 00:01:54,000 --> 00:01:56,840 Speaker 1: in it and also is using Google Maps with the 38 00:01:57,400 --> 00:02:01,720 Speaker 1: my location option turned on, you are contributing to the 39 00:02:01,760 --> 00:02:04,960 Speaker 1: information that Google is using to generate those traffic overlays. 40 00:02:06,240 --> 00:02:08,240 Speaker 1: And that's pretty cool. Well, it depends on how you 41 00:02:08,240 --> 00:02:11,239 Speaker 1: look at it. You might be afraid, uh for example, 42 00:02:11,280 --> 00:02:14,200 Speaker 1: that hey, wait a minute, so I have Google uh 43 00:02:14,400 --> 00:02:17,720 Speaker 1: Maps for mobile turned on on my phone. I thought 44 00:02:17,760 --> 00:02:19,880 Speaker 1: I was just checking out the traffic. You mean they're 45 00:02:19,919 --> 00:02:24,720 Speaker 1: taking information from me? Uh. Google actually would would say 46 00:02:24,880 --> 00:02:27,359 Speaker 1: not to worry too much about that, because they are 47 00:02:27,600 --> 00:02:30,920 Speaker 1: they're not really taking any identifiable information from you. However 48 00:02:31,000 --> 00:02:33,919 Speaker 1: they are, um, they are also taking pains to mix 49 00:02:33,960 --> 00:02:37,320 Speaker 1: it in with other information, uh, taken from other customers. 50 00:02:37,360 --> 00:02:40,960 Speaker 1: So don't worry so much. You're you're not being peaked upon, 51 00:02:41,040 --> 00:02:44,400 Speaker 1: and they weren't aren't following you on your way to work? Right, UM, 52 00:02:44,560 --> 00:02:47,680 Speaker 1: probably let's give an overview of exactly what's going on 53 00:02:47,760 --> 00:02:50,280 Speaker 1: here so that we can kind of discuss where the 54 00:02:50,400 --> 00:02:53,600 Speaker 1: concerns come in and uh and how Google has decided 55 00:02:53,639 --> 00:02:56,600 Speaker 1: to try and meet those concerns. Because you you raise 56 00:02:56,600 --> 00:02:59,000 Speaker 1: a really good point, Pillette, I mean that there is 57 00:02:59,000 --> 00:03:01,640 Speaker 1: a privacy issue here. What if you're not driving to work, 58 00:03:01,960 --> 00:03:04,639 Speaker 1: What if you're driving to say, I don't know, maybe 59 00:03:04,639 --> 00:03:07,440 Speaker 1: you're driving to the hospital and you don't necessarily want 60 00:03:07,440 --> 00:03:09,359 Speaker 1: people to know that you have to go to the hospital. 61 00:03:09,400 --> 00:03:11,400 Speaker 1: You know, it's none of their business, it's your business. 62 00:03:11,840 --> 00:03:14,440 Speaker 1: And the thought of well, does this mean that there's 63 00:03:14,440 --> 00:03:17,640 Speaker 1: some technology tracking my every move and that if someone 64 00:03:17,720 --> 00:03:20,960 Speaker 1: were clever enough they could figure this out. Um, well, 65 00:03:21,000 --> 00:03:24,200 Speaker 1: we'll get to that. So generally, what's going on is 66 00:03:24,360 --> 00:03:29,040 Speaker 1: when you're using these these devices, the GPS receiver is 67 00:03:29,080 --> 00:03:33,440 Speaker 1: what is is identifying your location. Um. Now, they can 68 00:03:33,639 --> 00:03:38,120 Speaker 1: use cell towers to try and approximate your location, but 69 00:03:38,280 --> 00:03:42,400 Speaker 1: that's usually within about all. It's not really that accurate, 70 00:03:42,880 --> 00:03:48,040 Speaker 1: you know, it's it's several dozen meters at the at 71 00:03:48,040 --> 00:03:50,280 Speaker 1: the at best when you're talking about just cell towers, 72 00:03:50,760 --> 00:03:52,840 Speaker 1: you know, whereas GPS you're talking about a few hundred 73 00:03:52,840 --> 00:03:56,800 Speaker 1: feet max um. So cell towers not that great when 74 00:03:56,840 --> 00:04:00,800 Speaker 1: you're looking at trying to to figure out the traffic 75 00:04:00,800 --> 00:04:04,400 Speaker 1: patterns of a particular area, because if if it's narrow enough, 76 00:04:04,640 --> 00:04:06,840 Speaker 1: theoretically you wouldn't be able to narrow it down to 77 00:04:06,920 --> 00:04:09,760 Speaker 1: a specific street, right Like especially the cities laid on 78 00:04:09,800 --> 00:04:12,360 Speaker 1: a grid. You might be like, well North South travel 79 00:04:12,360 --> 00:04:14,240 Speaker 1: seems to be going pretty well, but we aren't really 80 00:04:14,280 --> 00:04:17,880 Speaker 1: sure which North South street this guy's on. GPS hower 81 00:04:17,920 --> 00:04:20,080 Speaker 1: gives you a much more specific location. So what happens 82 00:04:20,160 --> 00:04:23,200 Speaker 1: is you've got the GPS system identifying where you are, 83 00:04:24,000 --> 00:04:27,559 Speaker 1: and then uh, your phone is contacting the self cell 84 00:04:27,600 --> 00:04:31,680 Speaker 1: towers up on a pretty regular basis. As a matter 85 00:04:31,680 --> 00:04:34,159 Speaker 1: of fact, this wouldn't work if you didn't have a phone, 86 00:04:34,200 --> 00:04:36,640 Speaker 1: if you had just a GPS receiver, you'd kind of 87 00:04:36,680 --> 00:04:39,400 Speaker 1: be out of luck because a typical GPS receiver, just 88 00:04:39,440 --> 00:04:42,440 Speaker 1: a plain old receiver, is a receiver. It's not a transceiver. 89 00:04:42,520 --> 00:04:45,840 Speaker 1: It's not sending information back to the satellites. So Google 90 00:04:45,880 --> 00:04:48,719 Speaker 1: gets the information. Uh, the GPS information is going to 91 00:04:48,760 --> 00:04:51,640 Speaker 1: your phone, and your phone is contacting the cell towers, 92 00:04:51,680 --> 00:04:53,920 Speaker 1: and that's how Google's figuring out where you are, right. 93 00:04:53,960 --> 00:04:56,680 Speaker 1: And so what happens is it sees think of your car, 94 00:04:56,800 --> 00:04:58,440 Speaker 1: is just that little dot if you turn on the 95 00:04:58,520 --> 00:05:00,800 Speaker 1: my location you know you know I'm talking about. But 96 00:05:00,839 --> 00:05:02,920 Speaker 1: if you if you don't have it, here's what looks like. 97 00:05:03,279 --> 00:05:05,919 Speaker 1: You open up Google Maps, you turn on your my 98 00:05:06,000 --> 00:05:08,200 Speaker 1: location and then you get a little blue dot that 99 00:05:08,560 --> 00:05:13,359 Speaker 1: indicates your specific location on the map. As you move around, 100 00:05:13,360 --> 00:05:16,159 Speaker 1: the little dot moves around. Well, what happens is Google 101 00:05:16,200 --> 00:05:20,520 Speaker 1: will track how fast you're moving along a particular route 102 00:05:20,880 --> 00:05:25,000 Speaker 1: and extrapolate from that how traffic must be moving. So 103 00:05:25,680 --> 00:05:28,320 Speaker 1: this is not really useful unless Google is able to 104 00:05:28,320 --> 00:05:31,680 Speaker 1: do it with lots and lots of users, right, because, 105 00:05:31,720 --> 00:05:34,919 Speaker 1: for example, you could be walking down the street and 106 00:05:34,920 --> 00:05:38,800 Speaker 1: everybody else is moving quickly, so Google is saying, oh, well, 107 00:05:38,839 --> 00:05:42,800 Speaker 1: apparently traffic is flowing normally and this other person is 108 00:05:43,080 --> 00:05:45,320 Speaker 1: doing something else, So you would you would be an 109 00:05:45,320 --> 00:05:48,560 Speaker 1: anomaly in that case because all the other traffic moving 110 00:05:48,560 --> 00:05:50,480 Speaker 1: down the street is moving much more quickly than you are. 111 00:05:50,560 --> 00:05:52,799 Speaker 1: Or maybe your your car's broken down and you're pushing 112 00:05:52,800 --> 00:05:55,640 Speaker 1: it down the street, right. Yeah, so Google could could 113 00:05:55,680 --> 00:05:57,920 Speaker 1: ignore you in that case. But if you were the 114 00:05:58,000 --> 00:05:59,880 Speaker 1: only person in the area who happened to be you 115 00:06:00,000 --> 00:06:03,719 Speaker 1: seeing this, then Google's conclusion would be, Wow, traffic on 116 00:06:03,760 --> 00:06:06,720 Speaker 1: this street has crawled to a to almost a standstill. 117 00:06:06,760 --> 00:06:10,599 Speaker 1: Look at how slowly they're moving. So obviously, these sort 118 00:06:10,640 --> 00:06:13,800 Speaker 1: of systems are really only useful if lots of people 119 00:06:13,800 --> 00:06:17,800 Speaker 1: are already participating. Um, you can't just kind of go 120 00:06:18,000 --> 00:06:20,599 Speaker 1: right out of the gate with accurate travel information. You 121 00:06:20,640 --> 00:06:25,240 Speaker 1: really do need lots of different participants. So Google will 122 00:06:25,240 --> 00:06:28,880 Speaker 1: look at the big picture and the traffic overlay just 123 00:06:28,880 --> 00:06:31,159 Speaker 1: gives you an indication of how fast traffic is moving 124 00:06:31,200 --> 00:06:34,679 Speaker 1: along any individual streets. Google is not the only company 125 00:06:34,720 --> 00:06:37,839 Speaker 1: to take this approach. In fact, there was another company 126 00:06:37,880 --> 00:06:40,920 Speaker 1: that uh that some people in the tech industry were 127 00:06:40,960 --> 00:06:44,279 Speaker 1: really really excited about that. Were they were producing GPS 128 00:06:44,520 --> 00:06:47,760 Speaker 1: units that, uh, that seemed really innovative and use this 129 00:06:47,839 --> 00:06:51,040 Speaker 1: kind of feature where customers who use that that GPS 130 00:06:51,120 --> 00:06:57,000 Speaker 1: unit were contributing to the overall information about the city's traffic. Yes. Yes, 131 00:06:57,120 --> 00:06:58,920 Speaker 1: I was actually one of those people because I saw 132 00:06:59,000 --> 00:07:02,240 Speaker 1: the company technology at c e S two thousand eight, 133 00:07:02,720 --> 00:07:05,200 Speaker 1: and uh, I was really I was thinking how cool 134 00:07:05,240 --> 00:07:07,120 Speaker 1: it was that they had a way to, uh to 135 00:07:07,240 --> 00:07:10,080 Speaker 1: identify the businesses around where you were and give you 136 00:07:10,160 --> 00:07:13,760 Speaker 1: an idea of what was going on because uh, the 137 00:07:13,800 --> 00:07:16,920 Speaker 1: information from the GPS receiver was blended with Internet and 138 00:07:16,960 --> 00:07:19,920 Speaker 1: you could see you got sort of a um um 139 00:07:20,040 --> 00:07:24,200 Speaker 1: augmented reality effect. Really right, So, and I assume we're 140 00:07:24,240 --> 00:07:27,920 Speaker 1: talking about the same company. Let's make sure dash excellent. Well, 141 00:07:27,920 --> 00:07:31,040 Speaker 1: why oh my gosh, oh my gosh, listeners, you just 142 00:07:31,160 --> 00:07:35,760 Speaker 1: got to hear a renaissance festival slip up, I said, excellent. Well, 143 00:07:37,080 --> 00:07:40,040 Speaker 1: oh man, I've already been working there for a few weeks, 144 00:07:40,080 --> 00:07:42,160 Speaker 1: just in case you guys were wondering, and it is 145 00:07:42,160 --> 00:07:45,440 Speaker 1: starting to seep into my normal speech, So feel free 146 00:07:45,480 --> 00:07:48,440 Speaker 1: to write in and and chastise me for doing a 147 00:07:48,520 --> 00:07:52,600 Speaker 1: festivalism because I can't believe I did that. All right, anyway, 148 00:07:53,440 --> 00:07:58,520 Speaker 1: blooper real um the so so. Yeah, these two systems 149 00:07:58,520 --> 00:08:03,280 Speaker 1: work very similarly. You've got a centralized uh computing system 150 00:08:03,320 --> 00:08:06,120 Speaker 1: that is colating all this data and then sending it 151 00:08:06,160 --> 00:08:09,120 Speaker 1: back to the to the individual units. For the individual 152 00:08:09,160 --> 00:08:11,880 Speaker 1: units themselves are what is contributing to the data. It's 153 00:08:11,920 --> 00:08:16,680 Speaker 1: this kind of interesting circular system. And um, again, let's 154 00:08:16,680 --> 00:08:18,760 Speaker 1: talk about why you need a lot of people. It's 155 00:08:18,800 --> 00:08:22,480 Speaker 1: not just for the accuracy. It's also for privacy. Yes, 156 00:08:22,600 --> 00:08:26,840 Speaker 1: because imagine that Google institutes this and there's only one 157 00:08:26,920 --> 00:08:30,000 Speaker 1: person out there who happens to have the phone that 158 00:08:30,120 --> 00:08:32,360 Speaker 1: does this. All right, I mean, this is obviously just 159 00:08:32,640 --> 00:08:35,520 Speaker 1: a ridiculous example, But let's say that Let's say that 160 00:08:35,559 --> 00:08:38,720 Speaker 1: Palette is the only person in the world, or at 161 00:08:38,800 --> 00:08:41,319 Speaker 1: least the only person in Atlanta, let's say, who has 162 00:08:41,360 --> 00:08:43,320 Speaker 1: one of these phones and Google has already turned on 163 00:08:43,360 --> 00:08:45,760 Speaker 1: the system. That would mean that the system would become 164 00:08:45,840 --> 00:08:48,520 Speaker 1: not a traffic system, but a hey, where the heck 165 00:08:48,559 --> 00:08:51,680 Speaker 1: is Palette now system? I'm the one, in case you 166 00:08:51,679 --> 00:08:53,440 Speaker 1: were wondering, I'm the one wearing the red and white 167 00:08:53,440 --> 00:08:58,080 Speaker 1: striped shirt and the toboggan. Right, he's also carrying a cane. Um. 168 00:08:58,200 --> 00:09:00,920 Speaker 1: So anyway, the yeah, that that's why you need lots 169 00:09:00,920 --> 00:09:02,560 Speaker 1: and lots of people, because if you don't have a 170 00:09:02,559 --> 00:09:05,720 Speaker 1: lot of people, it actually is possible to figure out, oh, 171 00:09:05,760 --> 00:09:08,120 Speaker 1: this has to be you know so and so because 172 00:09:08,160 --> 00:09:11,200 Speaker 1: he lives in that part of town and look where's 173 00:09:11,240 --> 00:09:14,000 Speaker 1: he going? Oh my gosh. Well, another thing Google does 174 00:09:14,040 --> 00:09:17,719 Speaker 1: to try and minimize any chance that people would be 175 00:09:17,760 --> 00:09:21,640 Speaker 1: able to identify a specific individual based upon traffic patterns 176 00:09:22,040 --> 00:09:26,360 Speaker 1: is they will erase the origin and destination of any trip, right, 177 00:09:26,840 --> 00:09:29,960 Speaker 1: so that what they're looking at is they're just trying 178 00:09:29,960 --> 00:09:32,960 Speaker 1: to figure out the the speed of traffic along any 179 00:09:33,000 --> 00:09:35,920 Speaker 1: particular route. They're not interested in the starting point or 180 00:09:35,920 --> 00:09:40,200 Speaker 1: the finishing point, which is kind of interesting. So that's 181 00:09:40,280 --> 00:09:43,680 Speaker 1: that's Google's approach. They're saying, all right, well, we understand 182 00:09:43,720 --> 00:09:47,800 Speaker 1: your your privacy concerns, which is weird for Google. They 183 00:09:47,880 --> 00:09:50,680 Speaker 1: don't always seem to be really that concerned. Um, you 184 00:09:50,679 --> 00:09:53,360 Speaker 1: can ask people who had to you know, protest street 185 00:09:53,400 --> 00:09:57,200 Speaker 1: View for example, or buzz That's another really good example 186 00:09:57,240 --> 00:10:00,679 Speaker 1: about how Google sometimes seems to overlook the i'vous issue, 187 00:10:02,679 --> 00:10:04,600 Speaker 1: But yeah, they really did think about it this time, 188 00:10:04,679 --> 00:10:08,439 Speaker 1: and as Poulette was talking about earlier, they also try 189 00:10:08,480 --> 00:10:11,200 Speaker 1: to mix your data and with the data of other 190 00:10:11,320 --> 00:10:15,319 Speaker 1: users so that there is no you know, in visualization 191 00:10:15,400 --> 00:10:19,920 Speaker 1: in there um. So that's that's I mean, really that's 192 00:10:19,960 --> 00:10:22,679 Speaker 1: the basics. It's it's really just data collection and then 193 00:10:22,679 --> 00:10:26,360 Speaker 1: incorporation into the maps application. You know, there may be 194 00:10:26,559 --> 00:10:30,439 Speaker 1: another reason why Google erases the destination and the trip, 195 00:10:30,840 --> 00:10:35,560 Speaker 1: because really it's all about the journey anyway you want it, 196 00:10:36,040 --> 00:10:39,760 Speaker 1: the way you need it, anyway you want it so well, 197 00:10:39,840 --> 00:10:43,280 Speaker 1: and also another reason why you would want it to 198 00:10:43,280 --> 00:10:45,440 Speaker 1: be private, not just because of where you're coming from 199 00:10:45,440 --> 00:10:48,599 Speaker 1: and where you're going to, which is you know, obviously, 200 00:10:48,720 --> 00:10:51,720 Speaker 1: like let's say that you don't happen to know that 201 00:10:51,840 --> 00:10:54,600 Speaker 1: Jonathan likes on a Friday night to go to the 202 00:10:54,640 --> 00:11:00,240 Speaker 1: local gentleman's establishment and watch uh dancers. Jonathan doesn't. This 203 00:11:00,320 --> 00:11:02,600 Speaker 1: is just an example. But if but let's say that 204 00:11:02,679 --> 00:11:05,199 Speaker 1: you let's say that he did want to do that, well, 205 00:11:05,200 --> 00:11:07,680 Speaker 1: that would mean that Jonathan would probably not want you 206 00:11:07,720 --> 00:11:09,839 Speaker 1: to know that by looking at Google Maps. Well, that's 207 00:11:09,880 --> 00:11:12,079 Speaker 1: not the only thing. The only other reason you might 208 00:11:12,080 --> 00:11:16,640 Speaker 1: not want this information to be uh identifiable to you. 209 00:11:17,200 --> 00:11:19,080 Speaker 1: You might not want people to be able to tell 210 00:11:19,120 --> 00:11:22,840 Speaker 1: that you're, um, I don't know, speeding down a main 211 00:11:22,960 --> 00:11:26,640 Speaker 1: drag at a breakneck pace. Yeah, you might not want 212 00:11:26,679 --> 00:11:29,480 Speaker 1: folks to say, hey, I noticed on Google Maps last 213 00:11:29,559 --> 00:11:32,840 Speaker 1: night that you were drag racing down main street. Um. 214 00:11:32,880 --> 00:11:34,440 Speaker 1: That would also be a reason why you'd want it 215 00:11:34,480 --> 00:11:39,160 Speaker 1: to be privatized, so that both the the destination and 216 00:11:39,240 --> 00:11:42,240 Speaker 1: the speed would be kind of hidden from other people. 217 00:11:42,760 --> 00:11:46,040 Speaker 1: Right right, Jonathan, we noticed that you had the company 218 00:11:46,040 --> 00:11:50,880 Speaker 1: car out last night and you were speeding. Yeah, that 219 00:11:50,880 --> 00:11:53,160 Speaker 1: would have been really awkward, seeing as how I don't drive. 220 00:11:54,720 --> 00:11:57,360 Speaker 1: Just probably Actually, I'm sure I would end up in 221 00:11:57,360 --> 00:12:02,079 Speaker 1: a pond somewhere, possibly a pool somebody of water. The 222 00:12:02,120 --> 00:12:05,360 Speaker 1: pond would be good for you, I think, so. Um wow, 223 00:12:05,440 --> 00:12:07,599 Speaker 1: how many how many movie references are we going to 224 00:12:07,679 --> 00:12:12,520 Speaker 1: make in this podcast? At least one more? Yeah? Probably so. Uh. 225 00:12:12,600 --> 00:12:15,400 Speaker 1: One of the cool things to um that I hadn't 226 00:12:15,440 --> 00:12:17,920 Speaker 1: realized until I had started doing some research on on 227 00:12:18,080 --> 00:12:21,719 Speaker 1: the the traffic feature on Google site is that um, 228 00:12:21,880 --> 00:12:24,400 Speaker 1: Google is also keeping and this is also a bit 229 00:12:24,400 --> 00:12:26,320 Speaker 1: of a privacy concern, But I don't I don't know 230 00:12:26,360 --> 00:12:29,839 Speaker 1: that this is more so than anything else. Um, the 231 00:12:30,200 --> 00:12:34,920 Speaker 1: Google is keeping track of historical traffic information. So if 232 00:12:35,000 --> 00:12:38,120 Speaker 1: you are planning a trip, um, you know, say next Thursday, 233 00:12:38,160 --> 00:12:40,120 Speaker 1: to go to the airport, and you want to know 234 00:12:40,320 --> 00:12:42,720 Speaker 1: how traffic is on a Thursday morning going to the 235 00:12:42,720 --> 00:12:45,960 Speaker 1: airport between say eight thirty and ten o'clock in the morning, 236 00:12:46,559 --> 00:12:49,360 Speaker 1: you can look on Google and try to get a 237 00:12:49,360 --> 00:12:53,920 Speaker 1: prediction of how traffic will be in the future. It's 238 00:12:53,960 --> 00:12:56,640 Speaker 1: gonna clearly be over the roads because we'll all be 239 00:12:56,720 --> 00:13:00,760 Speaker 1: driving flying cars. Yes, I'm not gonna say it. I 240 00:13:00,800 --> 00:13:03,839 Speaker 1: came really close to making the other movie reference myself, 241 00:13:03,840 --> 00:13:05,880 Speaker 1: but I'm just gonna leave it up. Okay, where we're going, 242 00:13:05,960 --> 00:13:08,400 Speaker 1: we don't need roads. I told you we were having 243 00:13:08,400 --> 00:13:10,880 Speaker 1: that was that was the obvious one there. But no, 244 00:13:11,080 --> 00:13:14,480 Speaker 1: I think that's a very useful feature because, uh it 245 00:13:14,559 --> 00:13:17,560 Speaker 1: just seems like, um, you know, you could easily plan 246 00:13:17,640 --> 00:13:19,959 Speaker 1: a trip that way. Something time sensitive like that, especially, 247 00:13:19,960 --> 00:13:24,080 Speaker 1: it's going to uh benefit from having that information. So, um, 248 00:13:24,280 --> 00:13:26,640 Speaker 1: if you can, if you're not concerned about the privacy 249 00:13:26,640 --> 00:13:29,520 Speaker 1: feature thing, um, you know, there are lots of people 250 00:13:29,520 --> 00:13:31,600 Speaker 1: who are going to be concerned about regardless of what 251 00:13:31,760 --> 00:13:35,600 Speaker 1: the company tells you. UM. You know, then then it 252 00:13:35,640 --> 00:13:38,440 Speaker 1: can be useful to have that information and contribute to 253 00:13:38,960 --> 00:13:43,400 Speaker 1: everyone else's overall UH knowledge of traffic patterns over you know, 254 00:13:44,080 --> 00:13:47,120 Speaker 1: the recent past few minutes, you know, as far as 255 00:13:47,120 --> 00:13:50,520 Speaker 1: traffic is concerned, but also in the as in the 256 00:13:50,720 --> 00:13:53,880 Speaker 1: in terms of a historical sense. But you know, Google 257 00:13:53,920 --> 00:13:56,280 Speaker 1: is not the only one who does this. No, No, 258 00:13:56,480 --> 00:13:59,080 Speaker 1: Like we said, Dash does it as well, and UM 259 00:13:59,120 --> 00:14:02,280 Speaker 1: and some system incorporate other elements as well, not just 260 00:14:02,320 --> 00:14:07,320 Speaker 1: not just the user traffic or user experience, but they'll 261 00:14:07,400 --> 00:14:11,560 Speaker 1: incorporate things like if UH they might have a report 262 00:14:11,559 --> 00:14:14,800 Speaker 1: about a big event that's going on downtown and will 263 00:14:14,840 --> 00:14:18,920 Speaker 1: automatically factor that in when routing your trips so that 264 00:14:18,960 --> 00:14:21,160 Speaker 1: way you don't end up going through a street that's 265 00:14:21,160 --> 00:14:24,840 Speaker 1: been closed off for that day, or even some might 266 00:14:24,920 --> 00:14:28,640 Speaker 1: even incorporate weather reports. The more advanced you get, the 267 00:14:29,400 --> 00:14:33,000 Speaker 1: more information they'll they'll bring into UH to factor these 268 00:14:33,040 --> 00:14:35,080 Speaker 1: things in before you go on a trip, which is 269 00:14:35,120 --> 00:14:37,320 Speaker 1: really kind of cool. UM. A lot of them use 270 00:14:37,480 --> 00:14:41,440 Speaker 1: a system completely different from Dash and Google, which is 271 00:14:41,920 --> 00:14:44,880 Speaker 1: one of the things. A lot of them the GPS 272 00:14:44,880 --> 00:14:47,600 Speaker 1: receivers that are not phones they're just the just the 273 00:14:47,640 --> 00:14:51,960 Speaker 1: GPS receiver. They'll also have a second receiver in there 274 00:14:52,000 --> 00:14:58,320 Speaker 1: besides the GPS signal to to accept traffic message channel signals. Now, 275 00:14:58,320 --> 00:15:01,880 Speaker 1: the traffic message channel is UH. That's a way of 276 00:15:01,880 --> 00:15:05,800 Speaker 1: of sending traffic, real time traffic information out, usually over 277 00:15:05,880 --> 00:15:07,640 Speaker 1: an FM signal, but you can also do it over 278 00:15:07,720 --> 00:15:12,200 Speaker 1: satellite UM and you send that out to subscribers to 279 00:15:12,320 --> 00:15:17,600 Speaker 1: your service. So various companies have their own specific frequencies 280 00:15:17,600 --> 00:15:20,080 Speaker 1: like tom Tom has its own frequency in various cities, 281 00:15:20,120 --> 00:15:23,800 Speaker 1: that kind of thing. And the UH what will happen 282 00:15:23,920 --> 00:15:26,440 Speaker 1: is it'll the company will send the real time traffic 283 00:15:26,440 --> 00:15:30,680 Speaker 1: information out and so your GPS will update automatically. UH. 284 00:15:30,720 --> 00:15:33,440 Speaker 1: And this way, if let's say there's a big wreck 285 00:15:34,040 --> 00:15:37,600 Speaker 1: on one of the highways, it'll come back with that 286 00:15:37,680 --> 00:15:40,760 Speaker 1: information and give you the chance to reroute, you know, 287 00:15:41,480 --> 00:15:44,480 Speaker 1: in the middle of a trip. UM. There are some 288 00:15:44,520 --> 00:15:46,760 Speaker 1: problems with this technology and that a lot of the 289 00:15:46,760 --> 00:15:49,960 Speaker 1: companies that use it, UH, they kind of have their 290 00:15:50,000 --> 00:15:54,520 Speaker 1: system laid out on a grid, and so because that's 291 00:15:54,560 --> 00:15:56,280 Speaker 1: just the way the maps are, so when they have 292 00:15:56,400 --> 00:16:00,360 Speaker 1: to mark down where an incident occurs, but because it's 293 00:16:00,360 --> 00:16:02,960 Speaker 1: a grid, it's not. It's not terribly precise. It's not 294 00:16:03,000 --> 00:16:06,280 Speaker 1: like you can put a thumbtack exactly where the incidant happened. 295 00:16:06,320 --> 00:16:10,320 Speaker 1: You you get an approximation. Sometimes that approximation is wrong 296 00:16:10,440 --> 00:16:13,760 Speaker 1: because let's say that there's an incident that's at an intersection, 297 00:16:14,240 --> 00:16:17,000 Speaker 1: and it may mean that one road leading into the 298 00:16:17,040 --> 00:16:20,520 Speaker 1: intersection is affected, but the other three aren't. Well, if 299 00:16:20,600 --> 00:16:24,400 Speaker 1: the the grid isn't exactly placed at the intersection in 300 00:16:24,440 --> 00:16:27,560 Speaker 1: the proper way, it may show up as affecting the 301 00:16:27,600 --> 00:16:30,680 Speaker 1: wrong road. So your route may say, oh, well, you 302 00:16:30,720 --> 00:16:33,800 Speaker 1: can completely go this way, there's no problem here, it's unaffected, 303 00:16:33,800 --> 00:16:38,520 Speaker 1: when in reality, that's exactly where the problem is. Right, 304 00:16:38,600 --> 00:16:42,080 Speaker 1: So it's not as precise as it needs to be. Uh, 305 00:16:42,120 --> 00:16:45,880 Speaker 1: it's not foolproof in other words. Right, Meanwhile, you're cursing 306 00:16:45,880 --> 00:16:48,040 Speaker 1: because you got stuck in traffic somewhere right. You wanted 307 00:16:48,080 --> 00:16:51,240 Speaker 1: to turn left and the roads completely closed, and you 308 00:16:51,320 --> 00:16:53,240 Speaker 1: thought the roads the right was going to be closed. 309 00:16:53,320 --> 00:16:58,040 Speaker 1: But it's fine. Yeah, that's very irritating. Um. Going back 310 00:16:58,040 --> 00:17:01,160 Speaker 1: to something that you had said earlier talking about incorporating 311 00:17:01,960 --> 00:17:04,560 Speaker 1: weather and different events. Of course, a system like that, 312 00:17:04,600 --> 00:17:11,080 Speaker 1: it involves human interaction. UM, it's not completely completely computerized. UM. 313 00:17:11,160 --> 00:17:13,840 Speaker 1: Traffic Cast is one of those companies that does that. 314 00:17:13,960 --> 00:17:17,400 Speaker 1: And they UM they actually are the company that provides 315 00:17:17,520 --> 00:17:21,520 Speaker 1: Yahoo with its UM service. That's that you can see 316 00:17:21,520 --> 00:17:23,840 Speaker 1: on the Yahoo Maps website. UM. And one of the 317 00:17:23,880 --> 00:17:27,880 Speaker 1: things that UH that has improved about traffic information in general, 318 00:17:28,400 --> 00:17:31,760 Speaker 1: I think is that both systems, both Google and the 319 00:17:31,760 --> 00:17:34,840 Speaker 1: traffic cast system used on Yahoo and other sites UH, 320 00:17:34,960 --> 00:17:38,240 Speaker 1: is that they're starting to show information for arterial streets 321 00:17:38,280 --> 00:17:41,160 Speaker 1: as well, not just the major highways. UM. And it's 322 00:17:41,160 --> 00:17:45,720 Speaker 1: done traffic casts and traffic casts system is done in 323 00:17:45,800 --> 00:17:50,200 Speaker 1: a is handled partially you know, through human interaction, UM, 324 00:17:50,200 --> 00:17:53,600 Speaker 1: partially through other kinds of sensors, like for example, they 325 00:17:53,600 --> 00:17:57,240 Speaker 1: have the they use the remote Traffic microwave sensor, which 326 00:17:57,240 --> 00:17:59,520 Speaker 1: tells whether or not you're making burritos in your car. 327 00:18:00,640 --> 00:18:03,520 Speaker 1: Oh no, I'm sorry, that was my wrong notes No 328 00:18:03,680 --> 00:18:07,280 Speaker 1: it Uh I was really disappointed. Uh No, not so much. 329 00:18:07,800 --> 00:18:10,560 Speaker 1: Uh No. It's a traffic sensor that uses microwave signals 330 00:18:10,600 --> 00:18:12,840 Speaker 1: to figure out what's going on. It can actually go 331 00:18:13,119 --> 00:18:17,320 Speaker 1: across several lanes of traffic UH to identify, UM the 332 00:18:17,400 --> 00:18:20,800 Speaker 1: number of vehicles and their speed. Um, either you know 333 00:18:20,840 --> 00:18:24,360 Speaker 1: from the side or from the front, and uh it can. 334 00:18:24,520 --> 00:18:26,000 Speaker 1: As a matter of fact, you can monitor up to 335 00:18:26,080 --> 00:18:29,720 Speaker 1: eight lanes according to the information UM from traffic casts website. 336 00:18:30,119 --> 00:18:32,359 Speaker 1: But um, you know it can it can get an 337 00:18:32,400 --> 00:18:35,879 Speaker 1: idea of how fast you're moving. Now that's those are stationary. 338 00:18:35,960 --> 00:18:38,200 Speaker 1: It doesn't work the same way as having the the 339 00:18:38,520 --> 00:18:43,520 Speaker 1: the GPS system, uh through the maps functioning your phone. Um, 340 00:18:43,640 --> 00:18:45,840 Speaker 1: it doesn't get an idea over the same thing. So 341 00:18:45,880 --> 00:18:47,440 Speaker 1: they have to have it. They use a number of 342 00:18:47,480 --> 00:18:52,360 Speaker 1: collection methods, including including using GPS, but it's a it's 343 00:18:52,440 --> 00:18:54,159 Speaker 1: kind of neat too that they are able to do that. 344 00:18:54,200 --> 00:18:56,480 Speaker 1: And they're also in contact with the local governments who 345 00:18:56,520 --> 00:18:59,760 Speaker 1: have cameras and other systems set up so that they 346 00:18:59,800 --> 00:19:02,640 Speaker 1: can at monitor traffic. So in general, I would say 347 00:19:02,680 --> 00:19:05,480 Speaker 1: it's a lot easier to get an idea of what 348 00:19:05,600 --> 00:19:07,320 Speaker 1: your commute is going to be like before you leave 349 00:19:07,400 --> 00:19:09,440 Speaker 1: than it was just a few years ago. I mean, 350 00:19:09,440 --> 00:19:11,439 Speaker 1: because it seems to have come a long way in 351 00:19:11,440 --> 00:19:13,479 Speaker 1: a very short period of time. Right, They've they've got 352 00:19:13,520 --> 00:19:17,760 Speaker 1: a much more comprehensive list of data collection sensors and 353 00:19:17,760 --> 00:19:21,480 Speaker 1: and and methods. It's beyond just the users, which that's 354 00:19:21,520 --> 00:19:24,760 Speaker 1: a good good thing. I mean, I remember when when 355 00:19:24,760 --> 00:19:27,760 Speaker 1: I first started getting into the working world and I 356 00:19:27,800 --> 00:19:31,080 Speaker 1: was looking at at traffic reports things like that. Really 357 00:19:31,119 --> 00:19:34,680 Speaker 1: the only the only information you had where it came 358 00:19:34,720 --> 00:19:38,679 Speaker 1: from cameras that were placed along certain highways and you 359 00:19:38,680 --> 00:19:41,160 Speaker 1: can get a live look at what the traffic was like, 360 00:19:41,240 --> 00:19:43,440 Speaker 1: and you would get an approximation of the traffic. It 361 00:19:43,440 --> 00:19:46,119 Speaker 1: would you know, show up green, yellow or red. It 362 00:19:46,240 --> 00:19:48,560 Speaker 1: was all like the main highways. It was none of 363 00:19:48,560 --> 00:19:51,959 Speaker 1: the service streets and uh. And this is this is 364 00:19:52,440 --> 00:19:55,359 Speaker 1: much more useful for most people, I would think, because 365 00:19:55,400 --> 00:19:59,119 Speaker 1: it gives you a better glimpse of what traffics light 366 00:19:59,160 --> 00:20:02,720 Speaker 1: throughout the entire neighborhood. Yeah, or you know, then then 367 00:20:02,760 --> 00:20:05,119 Speaker 1: you got the other option, which is the traditional, uh 368 00:20:05,600 --> 00:20:09,920 Speaker 1: traffic copter five over the main thoroughfare. Yeah. Was that 369 00:20:10,040 --> 00:20:14,960 Speaker 1: an episode of w k RP. Anyway, he started pounding 370 00:20:14,960 --> 00:20:19,000 Speaker 1: his own chest because the cop chopper was was on 371 00:20:19,040 --> 00:20:23,239 Speaker 1: the Fritzi. I'm sorry, I had a traffic copter was 372 00:20:24,440 --> 00:20:27,600 Speaker 1: I had had the Flight of val Cree playing and 373 00:20:27,760 --> 00:20:34,240 Speaker 1: the Charlie don't surf there's another one for you. Um, 374 00:20:34,280 --> 00:20:36,680 Speaker 1: but yeah, well, the I think that I mean that 375 00:20:36,720 --> 00:20:38,720 Speaker 1: pretty much wraps up all the information I have because 376 00:20:38,720 --> 00:20:41,800 Speaker 1: this this topic is fairly cut and dry, especially for 377 00:20:41,840 --> 00:20:44,240 Speaker 1: a stuff topic it is. But um, but it was 378 00:20:44,280 --> 00:20:46,280 Speaker 1: kind of fascinating to me once I started looking at 379 00:20:46,320 --> 00:20:48,480 Speaker 1: the other ways that they measured traffic and explained some 380 00:20:48,520 --> 00:20:50,960 Speaker 1: of those weird beige boxes that they have on the 381 00:20:51,800 --> 00:20:54,240 Speaker 1: polls along the side of the road, right, you know, 382 00:20:54,280 --> 00:20:56,000 Speaker 1: I'd always wondered what some of those are. And I 383 00:20:56,000 --> 00:20:57,879 Speaker 1: know that there are other things too that they use, uh, 384 00:20:58,040 --> 00:21:00,600 Speaker 1: you know, like air pollution detect ors and things like 385 00:21:00,640 --> 00:21:02,760 Speaker 1: that that that that you'll see you on there. But um, 386 00:21:02,880 --> 00:21:04,840 Speaker 1: some of the boxes, uh, the next time you go 387 00:21:04,920 --> 00:21:06,520 Speaker 1: for a drive, some of the boxes that you see 388 00:21:06,520 --> 00:21:09,200 Speaker 1: with a little solar collector next to him maybe using 389 00:21:09,240 --> 00:21:13,400 Speaker 1: microwaves to uh check your car's speed and position out 390 00:21:13,440 --> 00:21:17,560 Speaker 1: to help the traffic people identify whether the roads are 391 00:21:17,600 --> 00:21:21,040 Speaker 1: clear or not. Yeah. Yeah, it's an it's neat stuff. 392 00:21:21,080 --> 00:21:24,000 Speaker 1: And I really do like the idea of crowdsourcing your 393 00:21:24,000 --> 00:21:26,639 Speaker 1: traffic information because I mean, when you think about it, 394 00:21:26,680 --> 00:21:29,320 Speaker 1: that's gonna, assuming the enough people are using it, that's 395 00:21:29,320 --> 00:21:33,720 Speaker 1: gonna give you probably the most accurate, big, big picture 396 00:21:33,800 --> 00:21:36,120 Speaker 1: view of what traffics like going you know how it's 397 00:21:36,119 --> 00:21:39,440 Speaker 1: going in the city, and um, I mean again, it 398 00:21:39,520 --> 00:21:44,960 Speaker 1: will depend entirely on whether people feel comfortable participating or not. Well, 399 00:21:45,280 --> 00:21:47,680 Speaker 1: I totally get that. I guess that that pretty much 400 00:21:47,680 --> 00:21:50,600 Speaker 1: wraps that up. Will go on to our second round 401 00:21:50,640 --> 00:21:58,480 Speaker 1: of listener mail. This listener mail comes from Jaden, and 402 00:21:58,560 --> 00:22:01,560 Speaker 1: Jaden says, Hey, Chris John, I just listened to your 403 00:22:01,560 --> 00:22:04,240 Speaker 1: Cyborg episode and wanted to tell you about something I read. 404 00:22:04,560 --> 00:22:06,760 Speaker 1: I read about a girl with some sort of degenerative 405 00:22:06,760 --> 00:22:09,560 Speaker 1: eye condition. She got a mechanical eye implanted where a 406 00:22:09,560 --> 00:22:12,520 Speaker 1: normal I would go. It had a camera and connected 407 00:22:12,520 --> 00:22:14,600 Speaker 1: to her optic nerve. It was pretty cool. I just 408 00:22:14,640 --> 00:22:16,639 Speaker 1: wanted to say that I love the podcast and to 409 00:22:16,760 --> 00:22:19,480 Speaker 1: keep them coming. I hope you could maybe tell me 410 00:22:19,560 --> 00:22:21,800 Speaker 1: about space shuttle tech or do a podcast on it. 411 00:22:21,800 --> 00:22:23,560 Speaker 1: And I'm only thirteen and love tech, so I want 412 00:22:23,600 --> 00:22:27,280 Speaker 1: to know everything about it. Please let me know. Thanks again, Jaden, Well, Jane. 413 00:22:27,359 --> 00:22:29,960 Speaker 1: We do have the space shuttle technology on our list 414 00:22:30,000 --> 00:22:32,359 Speaker 1: o topics, so it is on the list for us 415 00:22:32,400 --> 00:22:35,600 Speaker 1: to tackle, along with about a hundred and fifty other topics, 416 00:22:35,600 --> 00:22:40,760 Speaker 1: but we are determined to hit them all eventually. And 417 00:22:40,760 --> 00:22:44,640 Speaker 1: as for the the cyber cybernetic eye, I've heard of 418 00:22:44,920 --> 00:22:49,119 Speaker 1: an artist who wanted to have a camera implanted in 419 00:22:49,320 --> 00:22:52,679 Speaker 1: a prosthetic eye. She is missing an eye, and she 420 00:22:52,760 --> 00:22:55,520 Speaker 1: thought it would be an interesting way to capture images 421 00:22:55,800 --> 00:22:59,080 Speaker 1: from her point of view about as literally as as possible, 422 00:22:59,680 --> 00:23:03,080 Speaker 1: and even programming it in such a way where she 423 00:23:03,119 --> 00:23:07,480 Speaker 1: could control the method of capturing images by certain blinks. 424 00:23:08,200 --> 00:23:10,840 Speaker 1: If you blink twice and then something, it's it's capturing 425 00:23:10,880 --> 00:23:14,080 Speaker 1: still images instead of video, that kind of thing. She 426 00:23:14,119 --> 00:23:16,560 Speaker 1: had put out a call for engineers to try and 427 00:23:16,600 --> 00:23:20,000 Speaker 1: help her with this, but from the last I had checked, 428 00:23:20,520 --> 00:23:24,520 Speaker 1: it still has not become a completed project. And also 429 00:23:24,600 --> 00:23:26,680 Speaker 1: this was not connecting to her optic nerve at all. 430 00:23:27,040 --> 00:23:30,680 Speaker 1: It was merely to capture images and then you would 431 00:23:31,200 --> 00:23:34,640 Speaker 1: then upload the images to a computer. And there's also 432 00:23:34,680 --> 00:23:37,600 Speaker 1: a filmmaker who's trying to do something similar where he 433 00:23:37,640 --> 00:23:41,640 Speaker 1: wants to have a camera implanted in his eye socket 434 00:23:42,080 --> 00:23:45,600 Speaker 1: so that he could shoot a film um from his 435 00:23:46,119 --> 00:23:48,920 Speaker 1: own point of view, the same sort of thing, though 436 00:23:48,960 --> 00:23:52,479 Speaker 1: again not connecting to his brain in any way, just 437 00:23:52,600 --> 00:23:56,000 Speaker 1: connecting to an outside source or an outside a recording 438 00:23:56,000 --> 00:23:59,160 Speaker 1: device and then um his brain would eventually get around 439 00:23:59,160 --> 00:24:03,840 Speaker 1: to seeing it when you watch the playback. So interesting ideas. 440 00:24:04,160 --> 00:24:08,040 Speaker 1: Not not really cybernetic in the sense that it's not 441 00:24:08,880 --> 00:24:12,479 Speaker 1: enhancing their own abilities. It's really it's really just a 442 00:24:12,520 --> 00:24:14,600 Speaker 1: new way to hold a camera. If you really want 443 00:24:14,600 --> 00:24:16,880 Speaker 1: to think about it. Yeah, that's true. That's still kind 444 00:24:16,880 --> 00:24:21,679 Speaker 1: of cool and also scary. Come with me if you 445 00:24:21,720 --> 00:24:24,480 Speaker 1: want to live. All right, Well, that wraps up this 446 00:24:24,560 --> 00:24:28,840 Speaker 1: discussion of text stuff.
