WEBVTT - How Much Does Getting Stuck in Traffic Cost Us?

0:00:02.040 --> 0:00:07.000
<v Speaker 1>Welcome to brain Stuff from How Stuff Works. Pay their

0:00:07.040 --> 0:00:09.520
<v Speaker 1>brain Stuff Lauren vocal Bomb here. If you live in

0:00:09.640 --> 0:00:11.800
<v Speaker 1>or near a major city and drive a car, you

0:00:11.920 --> 0:00:14.720
<v Speaker 1>probably can't do much these days to avoid traffic, not

0:00:14.760 --> 0:00:18.160
<v Speaker 1>short of inventing your own vertical takeoff and landing technology anyways.

0:00:18.560 --> 0:00:21.240
<v Speaker 1>But what makes driving in some cities worse than others,

0:00:21.360 --> 0:00:25.279
<v Speaker 1>or one road more congested than another. Well, according to RICS,

0:00:25.320 --> 0:00:29.080
<v Speaker 1>a company that analyzes traffic and infrastructure data, it's traffic

0:00:29.120 --> 0:00:32.240
<v Speaker 1>hot spots. They define these as traffic jams that occur

0:00:32.320 --> 0:00:35.360
<v Speaker 1>at the same locations along a stretch of road. According

0:00:35.360 --> 0:00:38.000
<v Speaker 1>to Mark Burfield, the director of public relations at RICS,

0:00:38.120 --> 0:00:40.280
<v Speaker 1>key elements that define a traffic hot spot are that

0:00:40.320 --> 0:00:44.120
<v Speaker 1>they are reliable and predictable. If a commuter travels along

0:00:44.120 --> 0:00:46.120
<v Speaker 1>the same route at the same time every day and

0:00:46.200 --> 0:00:48.720
<v Speaker 1>it's always backed up at the same intersection or merge point,

0:00:49.080 --> 0:00:52.400
<v Speaker 1>that is a traffic hot spot. A recent study by Enrics,

0:00:52.440 --> 0:00:55.520
<v Speaker 1>released in September of seventeen, named and ranked the worst

0:00:55.560 --> 0:00:58.600
<v Speaker 1>traffic hot spots in the United States, one hundred and

0:00:58.640 --> 0:01:01.320
<v Speaker 1>eight thousand of them in the twenty five most congested

0:01:01.400 --> 0:01:05.479
<v Speaker 1>US cities l A, New York, Washington, d c Atlanta,

0:01:05.560 --> 0:01:09.319
<v Speaker 1>and Dallas were the top five containing the most ENRICS

0:01:09.360 --> 0:01:11.480
<v Speaker 1>conducted the study to learn more about the u S

0:01:11.480 --> 0:01:13.959
<v Speaker 1>transportation network. Is sort of a check up on the

0:01:13.959 --> 0:01:16.479
<v Speaker 1>well being of our roadways. The results will be used

0:01:16.480 --> 0:01:18.760
<v Speaker 1>to help determine the best and most efficient ways to

0:01:18.800 --> 0:01:22.840
<v Speaker 1>allocate money towards the country's transportation infrastructure. In other words,

0:01:22.920 --> 0:01:25.760
<v Speaker 1>by identifying the worst traffic hot spots and how they work,

0:01:26.000 --> 0:01:28.039
<v Speaker 1>public officials can make the upgrades that will have the

0:01:28.080 --> 0:01:30.839
<v Speaker 1>most benefit to drivers. For the purposes of the study,

0:01:30.959 --> 0:01:34.440
<v Speaker 1>ENRICS used its cloud based traffic analysis tool called Roadway

0:01:34.480 --> 0:01:38.119
<v Speaker 1>Analytics to analyze areas with frequent traffic jams and then

0:01:38.160 --> 0:01:40.880
<v Speaker 1>further narrowed those down to spots where speeds were typically

0:01:40.880 --> 0:01:44.920
<v Speaker 1>observed to drop below six of an uncongested reference speed

0:01:45.000 --> 0:01:47.760
<v Speaker 1>for at least two minutes at a time. In other words,

0:01:47.760 --> 0:01:50.000
<v Speaker 1>in a hot spot, traffical slow to less than half

0:01:50.040 --> 0:01:52.960
<v Speaker 1>its usual pace. The study also looked at the economic

0:01:53.000 --> 0:01:56.000
<v Speaker 1>costs in terms of wasted time, lost fuel, and carbon

0:01:56.000 --> 0:01:59.240
<v Speaker 1>emissions over the next decade. Using the data it gathered,

0:01:59.320 --> 0:02:02.920
<v Speaker 1>ENRICS created a global traffic scorecard, which ranks the cities

0:02:02.920 --> 0:02:05.640
<v Speaker 1>with the worst traffic and identifies the time and money

0:02:05.680 --> 0:02:09.720
<v Speaker 1>wasted in traffic congestion. The Global Traffic Scorecard rate cities

0:02:09.720 --> 0:02:12.400
<v Speaker 1>on a metric called the impact factor, which is calculated

0:02:12.440 --> 0:02:15.760
<v Speaker 1>by duration times distance times the number of traffic jams.

0:02:16.040 --> 0:02:18.560
<v Speaker 1>Here are some of the insights from the study. Though

0:02:18.600 --> 0:02:20.960
<v Speaker 1>New York has more traffic hot spots than any other

0:02:21.000 --> 0:02:23.679
<v Speaker 1>city in the study, drivers in Los Angeles pay more

0:02:23.840 --> 0:02:26.000
<v Speaker 1>due to hot spots. In l A, there were more

0:02:26.000 --> 0:02:28.680
<v Speaker 1>than one hundred and twenty eight thousand traffic jams just

0:02:28.880 --> 0:02:32.680
<v Speaker 1>during March and April. Of The worst single hot spot

0:02:32.720 --> 0:02:36.160
<v Speaker 1>in the country is near Fredericksburg, Virginia, on south at

0:02:36.200 --> 0:02:39.480
<v Speaker 1>Exit one three A, and the researchers estimate that it

0:02:39.480 --> 0:02:43.440
<v Speaker 1>will cost drivers there two point three billion dollars through

0:02:44.960 --> 0:02:47.239
<v Speaker 1>a jam in this hot spot lasts thirty three minutes

0:02:47.240 --> 0:02:50.200
<v Speaker 1>on average and stretches about six point five miles that's

0:02:50.200 --> 0:02:53.800
<v Speaker 1>about ten point four kilometers. The report concluded that across

0:02:53.840 --> 0:02:56.720
<v Speaker 1>all twenty five cities studied, traffic hot spots will cost

0:02:56.840 --> 0:03:00.200
<v Speaker 1>drivers four hundred and eighty billion dollars during the next

0:03:00.240 --> 0:03:04.240
<v Speaker 1>ten years. That's in lost time, wasted fuel, and carbon emitted.

0:03:04.600 --> 0:03:07.240
<v Speaker 1>When extrapolated across the country as a whole, the cost

0:03:07.280 --> 0:03:09.720
<v Speaker 1>of these hot spots is expected to reach two point

0:03:09.760 --> 0:03:14.880
<v Speaker 1>to trillion dollars that's trillion with a t through. Connected

0:03:14.919 --> 0:03:17.240
<v Speaker 1>cars and mobile devices are the key to this study

0:03:17.360 --> 0:03:20.280
<v Speaker 1>since they can be tracked by GPS. For example, if

0:03:20.280 --> 0:03:23.160
<v Speaker 1>you're using a smartphone to monitor traffic, researchers can tell

0:03:23.200 --> 0:03:25.639
<v Speaker 1>when and where you speed up, slow down, and come

0:03:25.680 --> 0:03:28.679
<v Speaker 1>to a stop. Though the data is anonymous, Intereacs isn't

0:03:28.680 --> 0:03:31.800
<v Speaker 1>the only company that takes advantage of our connectivity. For example,

0:03:31.840 --> 0:03:33.800
<v Speaker 1>if you use Google Maps to calculate a route and

0:03:33.919 --> 0:03:36.960
<v Speaker 1>get travel time estimates, those estimates are also courtesy of

0:03:37.120 --> 0:03:41.000
<v Speaker 1>real time GPS analytics. In addition to the tangible effects,

0:03:41.000 --> 0:03:43.640
<v Speaker 1>hot spots contribute to hard to measure problems, such as

0:03:43.640 --> 0:03:46.920
<v Speaker 1>a city's overall reputation for being a difficult or expensive

0:03:46.920 --> 0:03:49.840
<v Speaker 1>place to live, work, or visit. After all, no one

0:03:49.840 --> 0:03:52.000
<v Speaker 1>wants to go on vacation and wind up spending most

0:03:52.000 --> 0:03:54.640
<v Speaker 1>of their time in bumper to bumper traffic. That means

0:03:54.640 --> 0:03:57.000
<v Speaker 1>this data is extremely useful to cities that are trying

0:03:57.040 --> 0:04:00.320
<v Speaker 1>to improve their roads or their economics. For ex sample,

0:04:00.400 --> 0:04:04.200
<v Speaker 1>Chicago recently implemented strategies to ease congestion along I ninety,

0:04:04.320 --> 0:04:08.360
<v Speaker 1>which improved rush hour travel times by for westbound commuters.

0:04:08.760 --> 0:04:11.120
<v Speaker 1>A new lane was added on each side of the expressway.

0:04:11.320 --> 0:04:14.000
<v Speaker 1>Buses and emergency vehicles are now authorized to use the

0:04:14.040 --> 0:04:17.280
<v Speaker 1>shoulder lane, and real time traffic data, again gathered from

0:04:17.320 --> 0:04:21.840
<v Speaker 1>GPS enabled cars and mobile devices, is provided to commuters. California,

0:04:21.920 --> 0:04:24.480
<v Speaker 1>New Jersey, and Washington are among states that have recently

0:04:24.520 --> 0:04:28.560
<v Speaker 1>passed legislation to authorize funding for infrastructure upgrades. The goal,

0:04:28.720 --> 0:04:31.520
<v Speaker 1>presumably is to pave the way for smoother traffic when

0:04:31.720 --> 0:04:34.520
<v Speaker 1>or if autonomous cars become the norm, but there's no

0:04:34.600 --> 0:04:37.400
<v Speaker 1>reason that American drivers shouldn't benefit from this technology now.
