Speaker 1: Welcome to Stuff you Should Know from house Stuff Works
Speaker 1: dot com. Hey, and welcome to the podcast. I'm Josh Clark.
Speaker 1: With me is Charles Precious Bryant. How you doing, Precious.
Speaker 1: This is the podcast based on the novel Push by Sapphire. Yeah,
Speaker 1: that is absolutely right, word for word. Right, Jerry just
Speaker 1: got back because you did a spoiler. Yeah, for Precious,
Speaker 1: I've known for spoilers, aren't it? At least two? It
Speaker 1: was home? No, there was a there was um six
Speaker 1: ft under. There was another one I spoiled too, wasn't there? Yeah?
Speaker 1: There was one you spoiled that was a really old
Speaker 1: movie and I was like, come on, that movie is
Speaker 1: like fifteen years old. There's a statue of momentation? Was
Speaker 1: it Buck Ruband's eye? Yeah? I think that was it? Yeah,
Speaker 1: me too, Chuck. Yes, have you ever been in traffic?
Speaker 1: That's the best. I God, how do you set this up? Chuck?
Speaker 1: Do you like Steve Winwood? Yeah? You know I was
Speaker 1: gonna make a traffic a band comment. Have you ever
Speaker 1: seen the low spark of high heeled boys? Yeah? Yeah,
Speaker 1: that's it. I'm seriously I'm like trying to you know,
Speaker 1: he was like fifteen when he first joined traffic because
Speaker 1: he's a Lithario. Yeah, and by that I mean in Prodigy. Yeah. Yeah, traffic.
Speaker 1: I've been in traffic, buddy, you Yes, I have actually
Speaker 1: been in traffic. Um happens a lot because I don't
Speaker 1: ride Marta. You ride are fine, fine, crippled public transit
Speaker 1: system here in Atlanta. I'm never in traffic anymore. It's
Speaker 1: it's really been a huge difference in my life. Yeah. Well,
Speaker 1: I don't ride Marta because, um, I I usually I
Speaker 1: tend to avoid the smell of urine and um, reading
Speaker 1: while moving makes me sick. So I'm you know, plus,
Speaker 1: I value I used to value being able to smoke. Yeah, dude,
Speaker 1: I was just about to say that's why I used
Speaker 1: to drive. Yeah, and now I'm just like, I just
Speaker 1: do it out to have it. But I get caught
Speaker 1: in traffic a lot, and it stinks. I don't see
Speaker 1: you on a public transport. You're not not You're not
Speaker 1: that kind of social No. That's the other thing too,
Speaker 1: it's like, oh, hey, we work together, let's talk the
Speaker 1: whole time. No, I don't. I wear my sunglasses. It
Speaker 1: can be dark and raining, and I've told everyone here
Speaker 1: that if I have my shades on. That means the
Speaker 1: office is closed. Nice, the story is shut down. That's
Speaker 1: very nice stories. It looks super cool. Alright, So I'm
Speaker 1: a jerk that doesn't talk to coworkers. Now, moving on, buddy,
Speaker 1: It's okay, Chuck. Do you remember when we recorded quicksand yes,
Speaker 1: do you remember how we said that there's like a
Speaker 1: finite amount of stuff out there about quick thing, because
Speaker 1: there's a finite amount to know. There's a finite amount
Speaker 1: to know about traffic. But there's tons of information out there. Yeah,
Speaker 1: lots of little side things to know for sure. Yeah,
Speaker 1: Because ultimately, traffic happens in two ways. One is there
Speaker 1: is simply congestion. There's just too many cars on the
Speaker 1: road to carry to carry the flow of traffic quickly right.
Speaker 1: The other way is there is some unpredictable event that
Speaker 1: somebody's pulled over, somebody's broken down, there's a wreck, maybe
Speaker 1: an event that falls under congestion. Police have pulled over
Speaker 1: a traffic a speeder. People always slow down for that,
Speaker 1: and that's it. That's it. Those are pretty much the
Speaker 1: two broad categories that traffic can be created, right, um,
Speaker 1: And what happens in each of those events is somebody
Speaker 1: up front puts on their brakes and that that one
Speaker 1: press of the brakes travels backward all the way through. Right,
Speaker 1: when you have a bunch of different cars and different
Speaker 1: lengthes doing that at the same time, you have traffic
Speaker 1: You know what, that's called traffic wave. Yes, that's true.
Speaker 1: It's a domino effect. It's very easy, it is. And
Speaker 1: I came up with my own idea of describing this.
Speaker 1: You ready, Okay, So what I came up with is
Speaker 1: called the traffic bubble, okay, by Josh Clark. So the
Speaker 1: traffic bubble happens when somebody is driving along and presses
Speaker 1: their brakes for whatever reason. And just imagine that when
Speaker 1: they press that break, the big bubble grows over the
Speaker 1: car and it starts very slowly traveling backwards. And each
Speaker 1: car behind that car that's that created the traffic bubble
Speaker 1: isn't allowed to accelerate again until the traffic bubble is
Speaker 1: passed through them, right. But then the further back the
Speaker 1: traffic bubble goes, the more it dissipates, until eventually the
Speaker 1: people far enough back don't have to go through the
Speaker 1: traffic bubble and they're not affected by it. And does
Speaker 1: the bubble pass through the front cars to where they
Speaker 1: can then again accelerate. Is that how you see it
Speaker 1: as a moving bubble? Yeah? Over the bubble travels backwards
Speaker 1: over the traffic, and then once it passes over you,
Speaker 1: you're allowed to accelerate again. I believe you're just going
Speaker 1: to turn my friends traffic bubble like that or science
Speaker 1: or no breaking bubble. That's what I called it. Okay,
Speaker 1: breaking bubble. Yeah, like a piping effect. I hate that
Speaker 1: guy and he hates you. I don't care so traffic Josh,
Speaker 1: you want wink, might as well thrown a few stats here. Yeah,
Speaker 1: this one's that heavy. It is this this article by
Speaker 1: our colleague Jonathan Strickland at tech Stuff. Yeah, the Baldest
Speaker 1: podcast on staff. Here, Uh, what's a good stat here?
Speaker 1: The estimated traffic costs if you want to talk about
Speaker 1: cost of traffic, and about five years ago they estimated
Speaker 1: about seventy eight billion dollars and that's only fuel and
Speaker 1: waste of time. They don't take into account like pollution,
Speaker 1: environmental damage, health costs due to pollution. I mean it
Speaker 1: would really add up if you got to, you know,
Speaker 1: include those things. Yeah, and um with extra gas that
Speaker 1: was bought in two thousand seven, right, isn't that the
Speaker 1: year that studies connected recovered. Um, we in the US
Speaker 1: bought two point nine billion bill in extra gallons of
Speaker 1: oil because of traffic, and the annual cost for each
Speaker 1: individual motorists in America was like seven bucks just sitting there,
Speaker 1: just from traffic, not from you know, the gas that
Speaker 1: you need to actually get from point A to point B,
Speaker 1: but the extra gas used from idoling. Yeah crazy, yeah,
Speaker 1: And uh, I believe l A tops it out obviously
Speaker 1: at about two weeks a year you potentially spend sitting
Speaker 1: in your car and traffic. Yeah, l A has Um.
Speaker 1: There's this group called the Texas Transportation Institute, and I
Speaker 1: think they're out of A and M. Maybe they're awesome.
Speaker 1: They they they are like the leaders and studying and
Speaker 1: understanding and trying to mitigate traffic, right um. And they
Speaker 1: came up with this thing called the travel time index.
Speaker 1: Right Yeah. So basically you take the amount of time
Speaker 1: it takes and it's specific to each city, and it's
Speaker 1: for each city. It's not compared from city to city.
Speaker 1: It's compared to a certain time in one city to
Speaker 1: another time in the same city. So in an off
Speaker 1: peak time, say you can travel the speed limit, it
Speaker 1: takes you one hour to get from point A to
Speaker 1: point B. In Los Angeles, it would take one point
Speaker 1: nine two hours. Doubles your time basically during yeah, during
Speaker 1: rush hour, So it takes twice as long to get
Speaker 1: from point A to point B during rush hours compared
Speaker 1: to off peak. That's the travel time index. Yeah, and
Speaker 1: you know you have to do this anywhere you live
Speaker 1: where there's heavy traffic. But when I lived in l A.
Speaker 1: I used to have to always think, all right, well,
Speaker 1: this would take me forty five minutes normally. So and
Speaker 1: when you work in the movie business, you you can't
Speaker 1: be late. That's just not one of the things you do.
Speaker 1: You've got to be there on time or early. So
Speaker 1: you're like, well, it's supposed to take me forty five minutes,
Speaker 1: I'm gonna give myself like two hours. I gave myself
Speaker 1: more than double to get anywhere I needed to go.
Speaker 1: That's that's very smart. It's awful, is what it is. Yeah.
Speaker 1: L A's kind of bad, but chuck, we have it
Speaker 1: pretty bad too. Yeah, Land is really bad. Among like
Speaker 1: probably I think the top three or four. I heard
Speaker 1: a year or so ago that Atlanta had toppled l A.
Speaker 1: But I never saw any citation. Well all those It
Speaker 1: depends on how they are rating it. Some they rate
Speaker 1: the differently, like the amount of time you spend in
Speaker 1: your car commuting or the amount of time you sit idoling,
Speaker 1: So it kind of depends. But Atlanta's way up there. Boston, Seattle,
Speaker 1: San Francisco. Actually I think Boston's absent from that. Oh really,
Speaker 1: I think that they have made some moves that have
Speaker 1: kind of mitigated traffic and gotten them off some of
Speaker 1: the I know, the Big Dig was messing everything up.
Speaker 1: The Big Dig was just killing people. Yeah, and d
Speaker 1: C is awful. Have you ever driven around there? Uh No,
Speaker 1: I haven't. You was talking about how especially during the summer,
Speaker 1: during the travel or the tourist season, it's just mind numbing,
Speaker 1: is yeah. I mean way out into the suburbs in
Speaker 1: Virginia and Maryland sitting there. You know what they did
Speaker 1: in l A that I saw one time that had
Speaker 1: never seen was I was going down the highway one
Speaker 1: day and I noticed everyone was slowing down. And I
Speaker 1: looked up ahead on the express Ay and there were
Speaker 1: to California Highway patrol cars doing huge slow ses back
Speaker 1: and forth on the six lanes of expressway, not letting,
Speaker 1: like keeping everyone back like a nask, like a like
Speaker 1: a paste. Yeah, like a pace car. But you know
Speaker 1: they weren't driving straight. They were driving these big s.
Speaker 1: Is like, don't go by me. I've never seen that
Speaker 1: before in my life. What would have made it even
Speaker 1: funnier is if they've been driving those s with their
Speaker 1: hands out their window and their guns just shooting into
Speaker 1: the area while they were doing it. That would really say,
Speaker 1: don't drive past me. Yeah, that would have been great.
Speaker 1: And apparently that was they do that. It's a I
Speaker 1: don't know what they call it, but that's too slow
Speaker 1: everyone down. It's called being a yes. And on that note,
Speaker 1: my friend Derek has a joke about Atlanta traffic, and
Speaker 1: he's right, because Atlanta before their traffic, everyone's driving really
Speaker 1: really what fast. Yeah, that's one of the great characteristics
Speaker 1: about Atlanta. As far as I'm concerned, you go as
Speaker 1: fast as you can. I mean, the the average um
Speaker 1: flow of traffic I would say, is about seventy miles
Speaker 1: an hour around here. And that's with like a lot
Speaker 1: of people all around you. Yeah, everybody's bumper, a bumper
Speaker 1: going at least seventy, and the cops don't pull you
Speaker 1: over unless you're going over seventy and even then, like
Speaker 1: it's usually like you're going eighty or ninety when you
Speaker 1: get pulled over because everybody else is going seventy. Right,
Speaker 1: And that's my buddy Derek's joke is in Atlanta, and
Speaker 1: it's really true. It's not a joke. Everyone drives as
Speaker 1: fast as they can every day until someone and then
Speaker 1: someone wrecks, right, and then traffic backs up every single day.
Speaker 1: That's Atlanta traffic. Are we done? So let's just sit
Speaker 1: here and do traffic stories, just talk about what what
Speaker 1: angers us? So check there's a lot of smart people
Speaker 1: who study traffic because, like you said, there's um, what
Speaker 1: was it, how much money in two seventy eight billion
Speaker 1: just from fuel and wasted time? Yeah, because think about it,
Speaker 1: a person's time is money, right, and if you're sitting
Speaker 1: in traffic and sure one of those jerks like me
Speaker 1: who has an iPhone that emails while he's driving, then
Speaker 1: you're wasting money, right. Um. And actually there was this
Speaker 1: there's a group called the Commute Solutions that are out
Speaker 1: of Santa Cruz and they calculated the actual cost per
Speaker 1: mile of driving, not just traffic, but driving to each
Speaker 1: person is one point nineteen one dollar nineteen cents per mile. Yea,
Speaker 1: and that includes everything. I don't know how they came
Speaker 1: up with that number, but check it out. Well, if
Speaker 1: we're talking about highways and stats, we might as well
Speaker 1: talk about the same. Texas group did a study and
Speaker 1: um they found that traffic over the past years has
Speaker 1: increased a and by they predict it will go up
Speaker 1: another And here's what's remarkable. One only one of all
Speaker 1: our roads are highways, yet they shoulder half the traffic,
Speaker 1: half the car travel. Yeah. Crazy, It is crazy. And
Speaker 1: you don't usually think about when you think about traffic.
Speaker 1: I usually think about the highway myself, although I rarely
Speaker 1: get on the highway anymore. It's all surface streets that
Speaker 1: I take to and from work. Yeah, what do you go?
Speaker 1: Druid Hills Piedmont and I go basically up Piedmont r um.
Speaker 1: But it's it's traffic every day. But I don't think
Speaker 1: of it as traffic. When I think of traffic, I
Speaker 1: think of seventy five at rush hour and just like
Speaker 1: UH exit ramps backed up the the thing is is
Speaker 1: our surface streets are also intended to handle overflow of
Speaker 1: highway traffic. Right, not just people who are backed up
Speaker 1: from the exit ramp back onto the street, but I
Speaker 1: mean people who are making a conscious decision like me
Speaker 1: to find a different way that doesn't have anything to
Speaker 1: do with the highway. Right. And they found that if
Speaker 1: you want to widen a highway, I think we talked
Speaker 1: about this in like the urban planning one, um that
Speaker 1: when you when you widen the highway, Um, there's something
Speaker 1: called latent demand. It's a theory that if you want
Speaker 1: in the highway, people like me are going to be like,
Speaker 1: oh well, now there's a leven lanes instead of five,
Speaker 1: so I'll just hop on the highway. And so the
Speaker 1: demand increases in step with the widening of the lanes.
Speaker 1: So it actually doesn't mitigate anything by adding more lanes
Speaker 1: to a highway, right. I think they said the only
Speaker 1: way that will work is if they outpaced demand with lanes,
Speaker 1: and that just doesn't happen. There's too many cars. But
Speaker 1: that kind of makes sense to throw that money then
Speaker 1: instead into upfront costs for a light rail system. Yeah,
Speaker 1: you know, you hippie, I actually I'm still holding up
Speaker 1: for personal rapid transit. That was a palette in me podcast,
Speaker 1: but it was interesting. It's a good one. Uh, ramp metering,
Speaker 1: if if you're talking about solutions, that's another one. And
Speaker 1: they had these in l A. And they have them
Speaker 1: here in Atlanta now. It's where when you go to
Speaker 1: get on the highway. Now they have stop lights that
Speaker 1: just allow like one car through every few seconds. So
Speaker 1: you know, when you get on at Freedom Parkway, I
Speaker 1: used to fly around that and jump into traffic and
Speaker 1: squeeze in however I could, and um, that's you know,
Speaker 1: I was one of those jerks causing traffic. Well, I
Speaker 1: think anybody entering is that, because again with traffic, especially
Speaker 1: with just straight up congestion, there's just too many cars
Speaker 1: in one place, especially when you have a line of
Speaker 1: traffic and then more people directly adding to that lane. Yeah. Right,
Speaker 1: But ramp metering really really works. They did a study
Speaker 1: in Minnesota. They have four d and thirty rant meters
Speaker 1: and in two thousand they shut them all down for
Speaker 1: seven weeks and during that time traffic accidents increased. And
Speaker 1: then afterward they re reinstituted it and they saw the
Speaker 1: capacity increased by fourteen, and they walked away from that
Speaker 1: project going like with their hands in their pockets. Yeah,
Speaker 1: like we should probably not tell anybody about that. Yeah.
Speaker 1: I was trying to do a Minnesota accent, but that
Speaker 1: was pretty good. I couldn't do it. I said it
Speaker 1: was Oh, I know, it wasn't bad though, that's how
Speaker 1: they say it. H O V lanes is another thing
Speaker 1: that they've done pretty much countrywide, carpool lanes as help.
Speaker 1: I always forget when I have another person in the car, though,
Speaker 1: Uh yeah, I'll get like halfway where I'm going and say,
Speaker 1: oh man, let's get in the carpoal lane. Yeah. I
Speaker 1: have to say though. The h O V lane, to me,
Speaker 1: it's it's an extension of the fast lane. So you
Speaker 1: get the fast ling and then you have the h
Speaker 1: O V lane, And I hate it when it's the
Speaker 1: fast lane is just the fast ling. The HOV lan
Speaker 1: is like, I drive as slow as I want, but
Speaker 1: I have, you know, four people in my car, agreed,
Speaker 1: it makes it difficult. It's it's kind of like the
Speaker 1: h O V lane to me is you have two
Speaker 1: or more people and you're willing to drive ten miles
Speaker 1: faster than anybody else on the highway agreed. And since
Speaker 1: we talked about pet peeves in our last podcast. My
Speaker 1: one of my largest pet peeves is when I'm sitting
Speaker 1: in traffic and I'll see people speeding by me in
Speaker 1: the H O V lane by themselves. Nothing bothers me
Speaker 1: more than people that think the rules don't apply to them.
Speaker 1: I hate that time. I hate those people or people
Speaker 1: who um use the shoulder and just drive along in
Speaker 1: traffic as far as they can to get like fifty
Speaker 1: cars ahead. Yeah. I almost got plowed over in l
Speaker 1: A one time. I was getting out to get in
Speaker 1: the regular exit lane and almost got creamed by a
Speaker 1: truck that was on the shoulder. And I screamed at
Speaker 1: him that he almost killed me, and he says, what
Speaker 1: are you a cop? That's l A for you? It
Speaker 1: was like, he literally almost killed me. What are you
Speaker 1: a cop? If you were a cop, you'd be making
Speaker 1: lazy s's in front of trying firing my gun into
Speaker 1: the air. Exactly what else, Josh, Uh, there's lanes. We
Speaker 1: already talked about that. Whether there's that one, then there's
Speaker 1: um probably the most uh contentious idea congestion pricing, which
Speaker 1: is basically taxing people to drive. And there's a guy
Speaker 1: named Alistair Darling. I don't know if he's still the
Speaker 1: Transportation secretary baby something. You have a rock star in
Speaker 1: the transportation world, because he was a huge proponent of this,
Speaker 1: and he said in England. In England, yeah, he was
Speaker 1: the British Transportation in secretary. He basically said, you know,
Speaker 1: cars exact a toll on the environment and on the road, um,
Speaker 1: just by driving on him, So we should charge people
Speaker 1: to drive on the roads. What he failed to mention
Speaker 1: is that we already do. There are things called taxes
Speaker 1: and those are meant to pay for the roads. Right,
Speaker 1: he's forgetting about, you know, all the other misused money. Um.
Speaker 1: But they did actually have one in Great Britain. Do
Speaker 1: they still chuck, No, I don't think they ever instituted.
Speaker 1: They had a pilot program from two thousand three to
Speaker 1: seven and it worked like a champ for him in
Speaker 1: London at least. Yeah, there was a thirty percent dropping congestion,
Speaker 1: decrease in in fossil fuel consumption, decrease in CEO two emissions,
Speaker 1: So like in London, Singapore, Stockholm, San Francisco, San Francisco,
Speaker 1: did they institute one No, San Francisco is studying a
Speaker 1: New York Bloomberg has proposed it and they've studied it.
Speaker 1: And I just pulled this from this week. Actually, Lord
Speaker 1: Adonis is actually he's the Transport Secretary. Unless it's a
Speaker 1: new guy. What was your guy? His name is Lord Adonis.
Speaker 1: Lord Adonis, the Transport Secretary came up with a new
Speaker 1: hotel student. Yeah, that's where Joshuly staying in New York
Speaker 1: under Lord uh he It says it's ruled out the
Speaker 1: introduction of a national road pricing for the next parliament.
Speaker 1: But they uncovered that civil servants are still involved with
Speaker 1: the project and spending money on research even though they
Speaker 1: supposedly took it off the table. It was kind of
Speaker 1: a secret that they were still like tinkering with ou.
Speaker 1: I thought you were like saying this, these people were
Speaker 1: paying for this research on their own paychecks. No, but
Speaker 1: they've sunk seven point two million pounds that I guess
Speaker 1: the public didn't know. They thought it was off the table.
Speaker 1: So they're kind of under some hot water, in some
Speaker 1: hot water. They're they're in some deep quicksand yeah, they
Speaker 1: said Golden Brown and Alista Dawling had been caught red
Speaker 1: handed planning a spy in the sky sis him nice. Yeah, yeah,
Speaker 1: because I guess we should probably explain congestion pricing. Basically
Speaker 1: every car on the road. I guess when you would
Speaker 1: go get your vehicle tag or something, you also get
Speaker 1: a radio frequency identifier, right, and as you're driving, some
Speaker 1: satellite is tracking you, or you pass through some sector
Speaker 1: or something like that, and all of a sudden you're
Speaker 1: being you're in a toll area and much like say, uh,
Speaker 1: one of those toll passes UM, you are sent a
Speaker 1: bill or there's like you have to set up like
Speaker 1: a credit card or a bank account, attach that to
Speaker 1: your to your tag, and it just draws money from
Speaker 1: it based on however much you drive in there. In Singapore,
Speaker 1: when they first instituted, there's an actually in UM they
Speaker 1: had a flat rate for downtown, which is the most
Speaker 1: congested during peak hours. You had to pay three bucks
Speaker 1: to just drive around downtown. You could drive around all wanted. Uh.
Speaker 1: And as they as as they've gotten better at it,
Speaker 1: they're they're getting a little fancy schmancy with it, you know, like, um, well,
Speaker 1: if you want to drive here, it's a dollar seventy
Speaker 1: d for twenty minutes, but you can back, you know,
Speaker 1: two blocks over and it's just fifty cents and so on. Well,
Speaker 1: that's one of the rubs that um, one of the
Speaker 1: big things is is in England at least in other
Speaker 1: places too. I think they've suggested paying more for peak
Speaker 1: hour so be flexible in your work schedule. But then
Speaker 1: of course people that are a friend of the poor
Speaker 1: say that's progressive taxation because white collar dudes can be
Speaker 1: all flexible and work from home, but the poor have
Speaker 1: to get up and go to work during peak hours.
Speaker 1: So you're they're basically paying for the road that the
Speaker 1: rich man drives on. Exactly, That's exactly right, and that's
Speaker 1: the big problem. I mean, aside from having to pay
Speaker 1: to drive with with a with a congestion tax. Yeah, um,
Speaker 1: what else can you do? Chuck? And also remember we
Speaker 1: were talking it's this isn't just highways surface streets to everybody,
Speaker 1: don't get all anxious, we're talking about surface streets as well. Yes, uh,
Speaker 1: surface streets you get a lot of suburban sprawl, you know,
Speaker 1: like here in Atlanta, you've got like out in Roswell
Speaker 1: twenty years ago, it was it was kind of desolate
Speaker 1: cow patties and now it's all uh, you know, young
Speaker 1: families moving out there who don't want to be around
Speaker 1: urban types. Yeah, and you have a lot of a
Speaker 1: lot more cars. Um you have again that that one
Speaker 1: of two ways that you can cause traffic. Just put
Speaker 1: more cars on a road than it than it's designed
Speaker 1: to hand. And then out in the boonies like that.
Speaker 1: They weren't built for you know, they were built for farmland.
Speaker 1: All of a sudden they got these suburban people moving
Speaker 1: out there, and so traffic lights is something they can do. Yeah,
Speaker 1: this one disturbed me. Um that even the so you
Speaker 1: have a traffic light that is on a timer, right, yeah,
Speaker 1: which is so much, especially when they're poorly timed. Decator
Speaker 1: is awful. Yes, yeah, decator is awful. There's another one
Speaker 1: for the Piedmont Park parking deck and it just does
Speaker 1: whatever it wants, no matter what time and day, and
Speaker 1: if there's a car, they're not and people are just
Speaker 1: stopped in either direction, right, And um, that's a time
Speaker 1: light and time lights are awful. They're awful. Right. Then
Speaker 1: you have um sensored lights, which are awesome, right because
Speaker 1: you just come up in the way to your car
Speaker 1: triggers it, yeah, those are good. Yeah. Or you have
Speaker 1: a mixed system that uses time timing and sensors and
Speaker 1: it changes depending on the kind of day where it is.
Speaker 1: It's like you can set up a citywide comprehensive traffic
Speaker 1: light plan. Some cities have this. Even the best mixed
Speaker 1: citywide comprehensive traffic light plan reduces congestion by one percent.
Speaker 1: Really yeah, yeah, Atlanta is bad about that, at least
Speaker 1: in my area. There's and Jerry can confirm this, she
Speaker 1: kind of lives over near me. But there's all these
Speaker 1: scenarios where you'll you'll stop at a light that's timed
Speaker 1: to not Part of the smart light system is that
Speaker 1: they're all time to work together. So like if you
Speaker 1: sit here at this corner and you take a ride
Speaker 1: on red, there's not another red light waiting on you,
Speaker 1: and then that turns green, and then thirty more feet
Speaker 1: there's another red light. They should be timed out to
Speaker 1: where they were green. In l A. It's like, I mean,
Speaker 1: that's the one thing I will say. There's a lot
Speaker 1: of traffic. It's just because the people they do the
Speaker 1: best they can. You look down, they have these long, long, long,
Speaker 1: straight streets in Hollywood, and late at night you'll be sitting,
Speaker 1: like on Hollywood Boulevard at a red light and you'll
Speaker 1: see wink wink, You'll see like eight lights turn green,
Speaker 1: all that new Balance commercial. Yeah, with that woman running
Speaker 1: and she pushes herself to make all the lights doomed.
Speaker 1: A failure, but still it was a nice effort. I
Speaker 1: would I would go longer in l A just to
Speaker 1: get off the highway, even if it took me longer,
Speaker 1: just to feel like I was moving. And chuck, I'm
Speaker 1: about to spoil it for all of our British, UK, English, Welsh, Irish,
Speaker 1: Scottish friends who are typing an angry corrective email about
Speaker 1: al Stir Darling. He is not a Transportation secretary. He
Speaker 1: was the British Secretary of State for Trade and Industry.
Speaker 1: Lord Adonis is the Transport secretary. That and me name
Speaker 1: We were talking about people um studying this kind of thing.
Speaker 1: There's all sorts of really cool quantifications for traffic. My
Speaker 1: favorite is the passenger car equivalent. Okay, so you have
Speaker 1: a passenger car is say a sitting at an averagity
Speaker 1: and Toyota camera, all right? Or to be fair, Honda accord. Right, Um,
Speaker 1: that is like just an average car that you can
Speaker 1: fit four people into and it drives down the road
Speaker 1: and it's pretty responsive. And um an suv or a
Speaker 1: bus or a van is not as responsive because they're
Speaker 1: larger and because they take up more space, they're slower
Speaker 1: to accelerate, and so they they exact a heavier burden
Speaker 1: on a highway during congest right, So what they've come
Speaker 1: up with our passenger car equivalent. So an suv is
Speaker 1: one point four pc, right, and then a a city
Speaker 1: bus is like four point four pc. It's like four cars, right, Yeah,
Speaker 1: it has the same as far as like accelerating after
Speaker 1: breaking and just the space that's taking up. That's the
Speaker 1: equivalent of a passenger car. So one good solution to
Speaker 1: traffic is everybody driving smaller car, no kidding, and virtual slots, right, yeah,
Speaker 1: what's the deal there. Each car has a certain amount
Speaker 1: of space it takes up, and don't try and fit
Speaker 1: into a slot that's a bit smaller than your car.
Speaker 1: Is that how you know? That's pretty much firstual slots
Speaker 1: like tetris. Yeah, if you just amagement that there is
Speaker 1: a basically a rectangle around your car like bubble a bubble,
Speaker 1: but not a break bubble. Okay, you want to avoid
Speaker 1: the brake bubble um, but this is more of a
Speaker 1: rectangle and it kind of hugs the sides your cars,
Speaker 1: but it's longer on the front and back. And if
Speaker 1: every everybody's car stays in these slots that are on
Speaker 1: the highway, you just kind of pull into them as
Speaker 1: you're driving, and the slots are going like all the
Speaker 1: same rate, then as long as there's not too many
Speaker 1: cars on the road, were more more cars than there
Speaker 1: are slots, there should be no traffic. Yeah, but that
Speaker 1: never happens because all this is pie in the sky still.
Speaker 1: Well yeah, because when invariably you're sitting in the lane
Speaker 1: and you're like that lanes moving now, and then you
Speaker 1: get over in that lane you're like, well, now that
Speaker 1: lanes moving, and you keep going back and forth where
Speaker 1: if you stayed where you are, if everyone stayed where
Speaker 1: they were, you would all get there quicker. Or if
Speaker 1: everybody just stayed at home. Yeah, yes, good point, but
Speaker 1: your jobs stay at home. Right, So that's uh, that's
Speaker 1: our two cents, and uh, if you want to learn
Speaker 1: more about traffic, we we've been killing the articles with
Speaker 1: cool flash animations, haven't we one? It has a flash
Speaker 1: animation about a traffic wave. Cool, no break bubble. I'm
Speaker 1: going to see about having somebody add one of those
Speaker 1: the term my friend. You can type in traffic I
Speaker 1: think it'll bring up a bunch of stuff in the
Speaker 1: handy search part how stuff works dot Com, which means
Speaker 1: it's time for listener questions. It's time for Facebook questions. Yes,
Speaker 1: as we said in that other podcast on quicksand we took,
Speaker 1: we post on Facebook. Hey, give us some questions. We'll
Speaker 1: answer like ten of them really quickly. We got in
Speaker 1: an hour. This comes from Chelsea. What's the most unusual
Speaker 1: thing you've ever eaten? Uh? Tripe for me, which is intestines.
Speaker 1: Go ahead, what's yours? Um. I've had fried chicken hearts,
Speaker 1: I've had beef tongue, tongue. My favorite is um bone
Speaker 1: marrow really highly highly recommend anywhere you can find bone
Speaker 1: marrow it, just eat it. The only place down here
Speaker 1: is rathbutons and it's okay, yeah you good wrath buns.
Speaker 1: You gotta get one of those steaks. No, not not rathbunds, steaks,
Speaker 1: regular wrath buns. Yeah. Strangely, he doesn't have bone marrow there,
Speaker 1: but yes, uh, those weird stuff all right, I got
Speaker 1: you questions right there. You want to read one? Yeah,
Speaker 1: I guess this one's from Jacob. If a tree falls
Speaker 1: in the forest and no one is around to here,
Speaker 1: and Jacob hyphenates no one, which frankly I find like flourish. Nice. Yes,
Speaker 1: except for a tape recorder which absorbs the radiant vibrations
Speaker 1: and can later play them back as audible waves. Did
Speaker 1: the tree really make a sound? The answer is yes, yes. Uh.
Speaker 1: Kristen says, where christ and Candice now? And who does
Speaker 1: the intro for the podcast? Chris Palette is um co
Speaker 1: host of Tech Stuff Now and has been for quite
Speaker 1: a while. He's made it hometown boy made Good. Candice

Speaker 1: out that the Georgia Bar, the Globe, and the Roadhouse
Speaker 1: made up the bar Muda Triangle and you could access
Speaker 1: them all through the alley to get to the next
Speaker 1: so most decided they could. Quite often you would hop
Speaker 1: around into State at Roadhouse. I hope Roadhouse still there.
Speaker 1: It's gotten to be, Yeah, it is. And then of course, um,
Speaker 1: I always liked Wilson Soul Food and Guthrie's, which in

Speaker 1: same thing. Yeah, I was automatic for the people, were you? Yeah?
Speaker 1: I lived right around the corner from there, so remember
Speaker 1: what was the name of that restaurant? I went to
Speaker 1: Weaverdece Automatic for the people. Yes, that was good too.
Speaker 1: I liked Wilson's because the owner walked around and he's
Speaker 1: like four ft tall and he shook hands with everybody. Right,
Speaker 1: nice guy? Um, and of course Harry Bassett's I never
Speaker 1: went there. Oh my god, that was a frat bar.
