More road traffic due to a recovering economy

Posted on by

The Texas A&M Transportation Institute suggests traffic has increased due to an improved economy:

America’s traffic congestion recession is over. Just as the U.S. economy has regained nearly all of the 9 million jobs lost during the downturn, a new report produced by INRIX and the Texas A&M Transportation Institute (TTI) shows that traffic congestion has returned to pre-recession levels.

According to the 2015 Urban Mobility Scorecard, travel delays due to traffic congestion caused drivers to waste more than 3 billion gallons of fuel and kept travelers stuck in their cars for nearly 7 billion extra hours – 42 hours per rush-hour commuter. The total nationwide price tag: $160 billion, or $960 per commuter…

Recent data from the U.S. Department of Transportation shows that Americans have driven more than 3 trillion miles in the last 12 months. That’s a new record, surpassing the 2007 peak just before the global financial crisis. Report authors say the U.S. needs more roadway and transit investment to meet the demands of population growth and economic expansion, but added capacity alone can’t solve congestion problems. Solutions must involve a mix of strategies, combining new construction, better operations, and more transportation options as well as flexible work schedules.

I’d love to know whether the average driver would prefer a depressed economy or more traffic. This could be an example of competing interests: a depressed economy could have ramifications for jobs and retirement savings but many people may not have to think about it if they have a job. Yet, if you have a job, an increasingly lengthy commute makes few happy. This might lead to people wanting the economy to be better but not wanting those people to drive. (If only all the new jobs could be telecommuting workers!)

Is the real story about the economy or is it about (a) an increasing population (though the population growth rate may be quite low, the US still added over 2 million people in 2013) and (b) cheaper gas over the last year?

We don’t want automated cars driving the current speed limits

Posted on by

Should automated vehicles follow all the current traffic laws or will they need to be changed?

When Delphi took its prototype Audi robocar from San Francisco to New York in April, the car obeyed every traffic law, hewing to the speed limit even if that meant impeding the flow of traffic.

“You can imagine the reaction of the drivers around us,” Michael Pozsar, director of electronic controls at Delphi, said at a conference in Michigan last week, according to Automotive News.  “Oh, boy. It’s a good thing engineers have thick skin. All kinds of indecent hand gestures were made to our drivers.”

And that indicates that a problem is brewing, argues Prof Alain Kornhauser, who directs the transportation program at Princeton University. “The shame of the driving laws is that they all sort of have a ‘wink’ associated with them,” he says. “It says 55 miles per hour, but everyone knows that you can do 9 over. If that’s the situation, why isn’t it written that way—with a speed limit at 64?”…

In fact, if all cars were autonomous and connected to each other wirelessly, they wouldn’t need stop signs even at the intersections of multilane highways…

I imagine following the speed limit in the Chicago area would lead to some very unhappy drivers. Theoretically, we might not even need speed limits with driverless vehicles as it would all be dependent on the conditions. This might mean that vehicles would go slower at times than drivers might like (perhaps in inclement conditions) but could go a lot faster and more safely even with a good number of drivers nearby.

But, if traffic laws need to be changed, when exactly would this happen? Presumably, it will take some time to introduce these vehicles onto the road and some time for them to grab a large part of the market. Of course, the government could push all new cars in this direction – particularly since they could be so much safer – but older models would still be on the road for some time. To change the laws, all the cars need to switch over at once, an unlikely event. Until all cars are driverless, traffic laws would have to be more conservative to account for drivers but that probably wouldn’t make the new owners happy.

Overall, I haven’t seen much discussion of how automated cars and cars with drivers will mix even as we creep closer and closer to this eventuality.

AP gives five solutions to nation’s growing traffic problems

Posted on by

The Associated Press discusses five ways to reduce traffic in America. Here are the quick summaries of each:

PUBLIC TRANSIT RENAISSANCE…

TOLLS ARE ‘HOT’…

DUMB CARS, MEET SMART CARS…

SELF-DRIVING CARS…

IN TECHNOLOGY WE TRUST

Perhaps we will have a situation where each of these options will be tried out in different places. For example, some cities will pursue mass transit – which can be quite expensive in already expensive areas – while others will simply add tolls to existing highways.

But, if I had to guess which options will prevail, I would guess numbers three through five which do not require people to give up their cars or the distance they commute to work and other places. (Some will voluntarily go for denser housing in more urbanized areas but others will interpret this as the government trying to force people out of suburban or rural living.) The first two require a lot of political will, either to spend the money for mass transit or to get people to pay new money for things they didn’t pay for before. Of course, the new technology won’t come cheap – it will be built into car costs in the future – but still appears to give the individual owners more options. Plus, American society tends to have quite a bit of faith in science and progress to solve problems.

Waze app ruins tranquil Los Angeles streets near major highways

Posted on by

Drivers have flooded a number of residential streets near major LA highways thanks to apps that reroute drivers around congestion:

When the people whose houses hug the narrow warren of streets paralleling the busiest urban freeway in America began to see bumper-to-bumper traffic crawling by their homes a year or so ago, they were baffled.

When word spread that the explosively popular new smartphone app Waze was sending many of those cars through their neighborhood in a quest to shave five minutes off a daily rush-hour commute, they were angry and ready to fight back.

They would outsmart the app, some said, by using it to report phony car crashes and traffic jams on their streets that would keep the shortcut-seekers away…

There are some things that can be done to mitigate the situation, said Los Angeles Department of Transportation spokesman Bruce Gillman, like placing speed bumps and four-way stop signs on streets. Lanes could even be taken out to discourage shortcut seekers, but a neighborhood traffic study would have to be done first.

A fascinating confluence of driving culture and new technology. Now, no street near the major highways are safe from traffic!

It will be fascinating to see how the city responds to complaints from local residents. Having rush hour congestion on your residential road can make for quite a different experience. It is a quality of life issue – who wants to have bumper to bumper cars in front – and I suspect the residents are also worried about their property values. Yet, what about the concerns of drivers on highways like the 405 that handle over 375,000 cars a day? This is a classic stand-off between individual drivers and individual property owners – who should win between the prized American driver and property-owner?

The real solution here is to keep looking for ways to reduce the number of vehicles on the highways in the first place. However, such plans at this point in LA’s development require a long-term perspective and lots of money.

Does posting the number of highway deaths in Illinois lead to safer driving?

Posted on by

A columnist discusses the effects of signs on Illinois Tollways that post the number of automobile fatalities on area highways:

The first time I saw one of those grim Illinois expressway signs was in 2012. I was merrily driving to the family farm in Indiana to visit my mom when I spotted a roadside sign dishing a little shock and awe to commuters and vacationers. There was something cold about the little electric bulbs in the sign above my expressway lane letting me know: “679 TRAFFIC DEATHS THIS YEAR.”

It made me think…

That’s precisely what the sign was meant to do. While many states were seeing fewer traffic fatalities during the summer of 2012, Illinois was seeing a substantial increase in the number of people killed on Illinois roads in the first half of that year. After the Illinois Department of Transportation started posting a running total of the dead in July, the last half of 2012 saw fewer fatalities than the last half of sign-free 2011.

Still, the number of fatalities went up in 2012, from 918 to 957. Last year, with those same signs updating our death toll daily and urging us to drive more safely, our fatalities inched higher again, to 973.

This evidence suggests the signs had little effect. This would line up with research that suggests drivers don’t pay all that much attention to road signs; hence, the suggestion that perhaps no signs might even be better. Indeed, the Illinois Department of Transportation has moved on to other strategies to reduce traffic deaths:

Michael Rooker, the actor who played Merle Dixon on TV’s “The Walking Dead,” stars in the latest IDOT safety campaign, a series of videos at thedrivingdeadseries.com and Facebook posts titled “The Driving Dead.” The postings don’t have anything close to the power of watching a young mother of two die while pinned in her car, but perhaps they will prove more effective than the road signs. The catchphrase of “The Driving Dead” gives those behind the wheel a new way of thinking about driving.

I would be curious to know whether IDOT is pursuing these strategies based on evidence that suggest they work or the agency is mounting what they think might work and/or what is publicly visible. Driving is a dangerous activity – one of the most dangerous the average person will partake in each day – and you would want solutions that work rather than guesses.

More protesters taking to the highways

Posted on by

Protesters around the world have moved to highways where they very visibly stop traffic:

In L.A., some of those demonstrators were arrested after shutting down traffic in both directions on the 101 Freeway. Another group of protesters flummoxed traffic downtown by laying down in the intersection of Cesar Chavez Boulevard and Grand Avenue.

They were not alone. Protesters took to I-95 in Providence. Highway 55 in Minneapolis. I-75 in Cincinnati. I-980 in Oakland. I-44 in St. Louis. I-35 in Dallas. And the Lincoln Tunnel and the West Side Highway in New York.

Across the nation, many of the protests that continue to simmer have moved from parks, plazas and civic centers to freeways and highways. The ongoing protests reflect national outrage following a grand jury decision that has vexed critics, to say nothing of the many black lives cut short in police shootings. Yet the move to the highways is something else: an evolution in the language and strategy of civil disobedience.

This isn’t just an American phenomenon:

It was late in September that protesters first took a major freeway in Hong Kong’s financial district. The protests gained critical mass more than a month after Brown’s death in Ferguson. When Hong Kong demonstrators clashed with police, they appeared to adopt the “Hands Up, Don’t Shoot” posture made familiar after weeks of protests in Ferguson.

This updates a post from a month ago about protestors blocking traffic in Atlanta. As noted before, this raises some interesting questions about public spaces and traffic safety. American drivers tend to like wide roads with more lanes because they think this will help them get places faster. (This is not the case on highly congested highways where simply adding lanes tend to increase the number of cars on the roads. Width does seem to matter on more normal streets where width tends to give drivers the impression they have some margin of error to go faster.) Highways tend to be some of the most empty places we have: no pedestrians, no bicycles, almost no one out of their car unless something has gone wrong. Yet, protesters blocking traffic can draw the attention of a lot of people at once both on the roads and from aerial shots that show the power even a relatively small number of people can have.

Is protesting on a highway as symbolic as some of the protests in shopping malls in the St. Louis areas? Does cutting off America’s transportation “arteries” make the same point as protesting in temples of capitalism? I’m not sure but it certainly is more unusual given the typical functions of highways.

LA to have the worst traffic on Thanksgiving getaway day

Posted on by

Add in more drivers this Thanksgiving and one firm says Los Angeles will have the worst getaway traffic on Wednesday:

Trips on Wednesday—deceptively nicknamed “getaway day”—are expected to take 36 percent longer on average, with peak times from 3 to 5 in the afternoon. Perhaps it would be more efficient for everyone to just Skype their family members while eating meals at home.

A rep for Inrix tells the LA Times that leaving either before or after the late afternoon peak times might spare drivers a little road pain, but that leaving the morning of Thanksgiving would be even better. The unfortunate folks picking up at LAX on Wednesday and traveling on the 110 south can expect the worst delays on their trip between 7 and 8 a.m., with delays of up to 15 minutes, which actually just sounds like regular holiday traffic at the airport.

Some interesting info – the data we have these days is pretty amazing – but this is such a limited issue. The two hour window in Los Angeles between 3 and 5 PM is expected to be worse and some of the other cities on the list have only one hour windows. If this is the case, then people should take note and try to leave at other times. Many people may not be able to help it given plane or work schedules but the traffic doesn’t have be as bad as suggested if people use the information well.

What it takes to approach a rate of zero traffic fatalities

Posted on by

An expert discusses Sweden’s efforts to get to zero traffic fatalities:

But in Vision Zero, the accident is not the major problem. The problem is that people get killed or seriously injured. And the reason that people get serious injuries is mainly because people have a certain threshold where we can tolerate external violence, kinetic energy. And we know quite well now how much violence we can tolerate.One of the major things with Vision Zero now is to put that more explicitly on the table. It’s like if we’re talking about the environment, and you know you have a certain threshold when it comes to poison, or whatever. You can tolerate up to a certain level. So it’s not just to stop the traffic. You can actually allow traffic. But if you have places in your system where you have unprotected road users and protected road users, according to Vision Zero you can’t allow a higher speed than 30 kilometers per hour [18.6 mph]…

I will say that enforcement plays of course a role in Sweden, but not so much. We are going much more for engineering than enforcement. If you have a very dedicated police staff and they think it’s the most important thing, then you can be quite effective working with police. But I don’t think you will get a safe system. You will reduce risk, but you will not achieve a safe system.

What about camera enforcement?

We are doing it, but in a different way. First of all, it is a national policy. We have both rural and urban areas, and we work with both. And when it comes to safety cameras, which is what we call them, we have put them on most rural roads. We have one of the largest safety camera systems in the world, per population.

But they are not catching people — it’s nudging people. So we put up the cameras on a stretch, and we tell everyone, OK, now you’re going in this area, and in a friendly but firm way we say you have to keep the speed in this area because we have a history of crashes.

It sounds like this would create some interesting discussions in the United States: do we really want to nudge drivers in such directions or do we truly think cars and vehicles should the rulers of the road? Right now, many of our roads are geared toward helping drivers get from Point A to Point B as fast as they can. But, safety is an important issue and one that concerns a lot of people given the number of vehicle deaths.

Predicting more Thanksgiving traffic due to a closed car-to-plane gap?

Posted on by

One way to predict traffic on the roads at Thanksgiving is to look at the car-to-plane travel gap:

Drivers will make up about 89.5 percent of holiday travelers this year, a gain of 0.1 percentage point from 2013, while air passengers will drop by the same amount to 7.5, forecasts prepared by Englewood, Colorado-based IHS Inc. show. A 0.1 point increase may not seem like a lot, but based on last year’s estimate that 39.6 million people traveled by car for Thanksgiving, that would roughly equate to at least another 40,000 people piling onto America’s highways.

The car-over-plane travel choice is made easier by the fact that airfares aren’t coming down like gasoline pump prices are. While the plunge in oil has driven down wholesale jet fuel prices 17 percent since August, almost matching the 18 percent drop in retail gasoline, airfares have risen 3.4 percent over that time, data compiled by industry groups show…

“Right now the airlines aren’t in the sharing mood,” Rick Seaney, chief executive officer of the Dallas-based travel website FareCompare.com, said. “They just went through six years of multi-megamergers and dividing the country up by city with little or no competition, so they’ll pocket whatever difference they may get for a while.”

Gasoline’s drop will save the average U.S. driver about $500 annually, helping boost consumer spending, according to IHS. U.S. auto sales have risen 5.5 percent to 13.7 million in the first 10 months of 2014, on pace to be the strongest in eight years, Woodcliff Lake, New Jersey-based data provider Autodata Corp. said.

A few thoughts:

1. Having 40,000 more people on the roads at Thanksgiving is going to complicate traffic all across the United States? Spread these people cross hundreds of metropolitan areas and assume they aren’t all leaving at the same time (Wednesday after work) and adding that kind of volume may not matter much at all.

2. The prediction of future traffic is interesting to me. This reminds me of Carmageddon fears, first in Los Angeles (twice) and then in Chicago earlier this year. This seems like the creation of news: get prepared for more Thanksgiving traffic now! It is the kind of fear-based reporting done by many local news outlets about things like weather or traffic, fairly mundane events that occasionally turn out to be horrible.

3. The Carmageddon cases hint at another piece of this prediction: making such claims could change future behavior. If Americans hear that there will be more drivers at Thanksgiving, even just a few of them changing their plans (not driving or changing their departure times) might go a long ways toward relieving the predicted traffic. Perhaps this forecast is all part of some plan to actually reduce Thanksgiving traffic?

4. Just from personal observation: plane tickets appear to be really high during Thanksgiving, Christmas, and New Year’s this year. As the article notes, airlines are looking to make money and haven’t budged much in their prices even with the recent gas price drops.

 

 

When American protestors take to the highway

Posted on by

Americans like their highways free of obstructions. So, what happened recently when a group of protestors blocked one of Atlanta’s main highways at rush hour?

That was what made the images of last week’s protest on the road known as the Atlanta Downtown Connector so jarring. A few dozen individuals, including members of the group Southerners on New Ground, walked out onto that roadway and laid down a banner reading “#BlackLivesMatter.” This was one of several actions around the country protesting police violence and mass incarceration, and expressing solidarity with those who have been demonstrating in Ferguson, Missouri, over the killing of black teenager Michael Brown by white policeman Darren Wilson…

The protesters blocked traffic on I-75/85, one of Atlanta’s major commuter routes, for only a short time, but they managed to get the attention of the drivers who rely on that route before the police cleared them from the roadway without making any arrests…

Reaction to the protest was decidedly mixed among Atlantans, with some people going on Twitter to criticize the action with comments such as, “I support the protests in #Ferguson, but why are they shutting down a highway in Atlanta so that BLACK folks can’t get home from work?” and “Look, I get standing in solidarity w/ #Ferguson, but #Atlanta traffic is already bad. So yeah, if you’re stuck in that, I’m POd w/ you.”

Blocking city streets has been an urban protest tactic since there were urban protests…

Blocking major roads in the United States, however, is much more rare. Most notably, the Selma to Montgomery marches that were pivotal in the Civil Rights movement of the 1960s used U.S. Route 80, a move that was upheld in a ruling by Federal District Court Judge Frank M. Johnson, Jr. His opinion was deeply controversial at the time: “The law is clear that the right to petition one’s government for the redress of grievances may be exercised in large groups,” said the judge, “and these rights may be exercised by marching, even along public highways.”

While this summary doesn’t give many details, I would be really interested to hear how the police handled this. Any pedestrian activity, let alone an intentional protest, on a major highway would often be viewed as a concern. At the same time, this is a good way to get the attention of a lot of people for the unusual location of the protest.

The article ends on a note that such protests help make highways less removed from normal life. This is due to a long American history of generally wanting their roads to be for automobile travel. This means bicycling, walking on nearby sidewalks, slow vehicles, and any other impediments (including natural ones) are often scorned. Such thoughts and policies helped lawmakers and politicians ram highways through major cities and urban neighborhoods in the mid-1900s. In contrast, our cities don’t have as many public pedestrian spaces like many European or other global cities which are full of plazas, parks, and wide sidewalks.
