Traffic, corruption, and a 40 mile traffic jam in Lagos

Posted on by

A journalist recounts being stuck for 12 hours in a 40 mile traffic jam in Lagos and ties his experience to the level of corruption in Nigeria:

But the biggest problem appears to be the unsavory ties between Nigeria’s political and business elites. Under the military dictatorships of General Ibrahim Babangida and then General Sani Abacha, both from the north, a small group of northerners came to dominate the trucking business. These men have reportedly played a key role in shooting down every effort to improve or privatize the country’s moribund, British-built rail system, ensuring that almost all goods must move by road.

According to Tom Vanderbilt, the author of Traffic: Why We Drive the Way We Do (and What It Says About Us), “Traffic behavior is more or less directly related to levels of government corruption.” Vanderbilt cites a clear correlation between traffic-fatality rates per miles driven and a country’s ranking on Transparency International’s corruption index. (In terms of road safety, the Scandinavian countries fare the best; Nigeria is near the bottom of the list.)

In March, Nigerian authorities made an attempt to unclog the highway, arresting illegally parked truckers and confiscating 120 vehicles. The Nigeria Truck Owners Association retaliated by calling a one-day strike that crippled the ports. The next day, traffic was as calcified as ever. About half a dozen agencies—the Inter-Ministerial Implementation Committee on Port Approach Roads in Lagos, the Lagos State Traffic Management Agency, the Federal Road Safety Commission, the Vehicle Inspection Officers—share responsibility for keeping traffic moving on the highway, but all of them are considered toothless.

Does Vanderbilt’s correlation hold independent of a host of other factors (such as central government spending on highways, etc.)?

I suspect experiences like these would leave Americans much more grateful for their roads and highways which they can tend to complain about. It reminds me of the 2010 story of a “nine day, 100 km” traffic jam outside of Beijing. This sort of stuff simply does not happen in the United States, even in the worst case scenarios such as really bad accidents (like the smoke-caused one earlier this year in Florida) or natural disasters (such as evacuating New Orleans before Hurricane Katrina). Granted, Americans may lose many hours a year in congestion, particularly in big cities, but the traffic does eventually clear and it does have a predictability to it. In other words, well-paved, maintained, and policed roads should not be taken for granted: they aren’t guaranteed in much of the world.

Getting drivers to change their commuting patterns by giving them chances to win money

Posted on by

Scientists have developed a new way to fight the congestion battle: if drivers change their commuting patterns, they would have a better chance of winning money.

Some urban areas, including London, Stockholm, and the capital of Singapore, have tried disincentives to discourage rush-hour driving. These congestion-pricing schemes have achieved some success, but problems persist. And implementing them is politically difficult; New York Mayor Michael Bloomberg abandoned his early effort to pare traffic in the Big Apple through commuter charges. But a growing number of transportation experts believe the same technology that enables cities to track cars and charge a fee when they enter designated congestion areas can be used to implement schemes that people will accept more readily. Rather than punishing old commuting habits, they reward new ones. For participants, opting to avoid rush-hour traffic means both saving time, and boosting their odds of winning a prize.

Instead of buying lotto tickets, participants in the Singapore program shift their commutes to off-peak hours to earn credits, which can be traded for chances to win cash. Participants earn one credit per kilometer traveled by rail, and three credits per kilometer for rail trips made during the hour before or after morning rush hour (7:30 to 8:30 a.m.). They can pick one “boost day” per week, when each kilometer traveled by rail earns five credits.

At Stanford, where the project is supported by a $3 million U.S. Department of Transportation grant, drivers who live off-campus and shift their commutes up to one hour outside the morning and evening rush hours can earn 10 cents per off-peak trip. That’s the boring, sure-fire option. Alternatively, they can use credits to play a simple online social game that randomly doles out cash prizes from $2 to $50. Cars are tracked using a small radio-frequency identification tag mounted to the windshield.

More than 17,500 Singapore commuters have enrolled in the pilot program, while just over 1,825 have enrolled in the Stanford project. And it seems these efforts to change travel behavior using games, or carrots, rather than sticks (such as congestion pricing) are paying off. Balaji Prabhakar, a Stanford engineering professor who developed both projects, said during a recent talk at the university’s campus in Palo Alto, California, that 11-12 percent of users in Singapore have shifted off-peak. Men tend to shift later, he said, while women generally shift earlier.

Is this the “gamification” of driving? Providing positive incentives rather than “punishing” people seems like it would be more effective in the long run. This reminds me of the new programs some insurance companies are rolling out where you get rewarded for driving more safely by having your rates reduced. At the same time, who is paying for these prizes? I assume this is funded by grant money or something like that but is this sustainable in the long run?

I wonder if there would be some unintended consequences of programs like these: instead of having horrible peak driving periods, traffic will simply be congested at more hours. Is it better to compress bad traffic into a certain number of hours a day versus spreading out the more congested hours? What happens if there are too many drivers all the time and incentives (or disincentives) wouldn’t really change much? I suppose we are a ways from this in some places but techniques like this don’t get at larger issues of having too many cars altogether.

Naperville cites traffic concerns and proximity to a residential area in rejecting McDonald’s near downtown

Posted on by

Naperville’s City Council voted Tuesday against a proposal from McDonald’s to build a restaurant just south of downtown. The cited reasons: traffic and proximity to a residential area.

The City Council unanimously turned down the proposed fast-food restaurant at the southeast corner of Washington Street and Hillside Road citing concerns about traffic at an already busy intersection and locating a 24-hour business close to homes…

The proposal was backed by both city staff and the plan commission. However, in a discussion that lasted more than an hour, councilmen focused on the potential for traffic tie-ups…Addressing the myriad of traffic concerns, William Grieve, a traffic engineer hired by McDonald’s, said a traffic study showed travel time through the intersection would only increase by about a second and double drive-through lanes would prevent backups.  Stillwell said the company would be diligent about addressing any problems if they arise…

But traffic wasn’t the only concern. Neighbors said they feared there would be increased noise and lights coming from the restaurant if it was allowed to stay open 24 hours as proposed.

Both Judy Brodhead and Joe McElroywere among the councilmen who agreed and said having a restaurant open 24 hours so close to homes was a deal-breaker regardless of the traffic issues.

I’m not surprised by this result: not too many residents would willingly choose to have a McDonald’s nearby and few people want more traffic. However, this seems a bit strange for a few reasons:

1. Washington is already a fairly busy road.

2. This intersection is near homes but there are already strip mall type establishments at this corner. In fact, I’m not sure there any homes that back up directly to this site as the DuPage River is to the east and all of the corners at the intersection are already occupied. The McDonald’s would replace a Citgo gas station, not exactly a paragon of civic architecture. Across the street is a Brown’s Chicken establishment. The other two corners include a cemetery and another strip mall type establishment.

3. The traffic study from McDonald’s seems to suggest there wouldn’t be any issues.

4. I wondered if this had anything to do with protecting the downtown but it is three blocks south of the downtown so it shouldn’t contribute to congestion problems there.

I wonder if there isn’t more to this story. Indeed, here are a few more details from the Daily Herald:

Council members admitted they were initially thrilled that McDonald’s wanted to open a downtown store on the southeast corner of Hillside and Washington streets. But when it came down to a plan that included five zoning variances, three landscape variances and a sign variance, they just weren’t lovin’ it.

So the McDonald’s required too many deviations from Naperville’s guidelines? While the restaurant might have needed 9 variances, the city could have made it happen if they really wanted to. Just how much did the pressure from the neighborhood matter?

Working on parking issues in Naperville’s downtown: shuttles? Parking garages? Perceptions about available spots?

Posted on by

This is an ongoing issue in Naperville: is there enough parking at peak times and, perhaps more importantly, do people think that there is enough parking? Here is part of the background to a discussion the city recently had about having shuttles to the downtown:

The topic came up again last year during the city’s strategic planning discussions, leading to planners’ latest look at the feasibility. Robles said they found the city’s cost per ride would be about $58, up from $45 in 2006 and the city hasn’t been hearing a demand from residents.

The issue, she said, seems to pop up every few years in part because some people have a perception there isn’t enough downtown parking. Including both public and private spots, there currently are about 3,300 downtown parking spaces.

A 2010 study showed on Friday nights – peak parking time – 77 percent of those spots tended to be full on average. The city will be doing a follow-up study this summer and Robles said she anticipates that occupancy percentage increasing into the lower 80s.

Reaching occupancy rates in the 80s tends to make people feel there isn’t enough parking, she said. But she hopes the city’s parking guidance systems that tell drivers how many spaces are really available in some facilities will help ease that perception.

Several thoughts about this:

1. I don’t think the “parking guidance systems” cited above are accurate all the time. For example, we drove into the Van Buren garage a few Fridays go because the sign said there was 45 spots available. We drove slowly, in a long line of cars, all the way to the top and all the back down again, finally finding a spot near the exit where someone was pulling out.

2. There is always street parking in the residential neighborhoods just north and west of the downtown. However, that would require a 5-10 minute walk for people. Is this the real issue: visitors (resident and non-residents) demand to park within a minute or two of their destination?

3. People perceive there is not enough parking when it occupancy is in the eighties percent range. This is fascinating: this still means that at least 1 of 10 parking spots are available and possibly as high as 1 out of 5. The issue of parking seems to be more about perceptions than actual availability.

4. Is this only an issue on Friday and Saturday nights between roughly early May and early September? In other words, how much parking does one build for 40 nights out of the year when those spaces will go unfilled at other times?

5. Has anyone ever tried to quantify for Naperville (or other places) how much business they might be losing by not having the sort of big box store/shopping mall parking lots?

6. Of course, this is not a new issue in Naperville. A few years ago, the city was considering building a three-level garage that would have replaced the Nichols Library lot but there was some opposition from residents (this parcel borders a residential neighborhood) and the city shelved the plans. Is building more garages really the answer in the long run?

Diamond grinding to reduce highway noise

Posted on by

One Lake County community is paying out of its own pocket to reduce noise on I-294 by diamond grinding the road:

The village [of Green Oak] will pay nearly $338,000 for a process called diamond grinding to hopefully reduce the racket along that stretch of road.

“The idea here was to grind it and produce a quieter pavement and pavement noise in the lower frequency range so it wasn’t so obnoxious,” Village Engineer Bill Rickert said.

That sound also described as “singing” by Rickert spurred several complaints after the tollway widening was completed about three years ago, and sent village leaders on a quest for a solution…

In the simplest terms, the concrete road surface had been tined or grooved perpendicular to the road surface, he said. The diamond grinding changed the grooves to run parallel, evoking “more of a corduroy-type feel,” and theoretically producing lower noise levels in frequencies less noticeable to the human ear.

While diamond grinding emerged as the village’s proposed solution, it isn’t used by the tollway as a noise reducing technique.

It would be interesting to see how this solution compares with building sound barriers – is diamond grinding cheaper or more effective? If this is an effective technique and people agree about this, why doesn’t the Tollway use it?

I have had some more interest in this lately because our neighborhood borders a busy arterial road that is being expanded from 2 to 4 lanes. Because of this, sound barriers have been installed. I don’t think they look too bad with a sort of faux beige brick look. Granted, I don’t live in a house that backs up to these walls and I assume there is a price (in housing value) to pay for backing up to these walls. Going further, at night we can faintly hear the nearby highway that is 1.5 miles away – it is a sort of background noise. But having grown up close to a railroad track which produced more sporadic but louder noise, can’t you simply get used to these things? Perhaps the difference here is that people in these neighborhoods near the Tri-State haven’t had this level of noise until the highway was expanded.

New goal in Chicago: no traffic deaths in ten years

Posted on by

The city of Chicago recently set an ambitious goal: there should be no traffic deaths in ten years.

The city of Chicago’s transportation department, headed by commissioner Gabe Klein, has released a new “action agenda” called “Chicago Forward.” It contains a goal that, as far as I know, has never to date been explicitly embraced by a major United States city:

Eliminate all pedestrian, bicycle, and overall traffic crash fatalities within 10 years…

[T]he city will be taking a multifaceted approach to traffic safety that includes engineering local streets to reduce car speeds; improving pedestrian and bike facilities; education; better data collection and evaluation; and increasing enforcement. Mayor Rahm Emanuel is strongly behind such measures even when they are politically unpopular, as was the case with a controversial speed camera bill that the mayor pushed through the City Council last month…

The idea of aiming for zero traffic deaths may be novel in the United States, but in Sweden, it’s national policy. In 1997, the Swedish Parliament passed the Vision Zero Initiative, with the “ultimate target of no deaths or serious injuries on Sweden’s roads.” Currently, the plan calls for an interim goal of reducing deaths and injuries to 50 percent of 2007 figures by 2020.

Has it worked? Zero is still some ways off – 2050 is the target date now — but the absolute number of traffic fatalities in Sweden continues to fall even as traffic is on the rise. And compared to the United States, their numbers are impressive: In 2009, Sweden had 4.3 traffic deaths per 100,000 population, while the United States had 12.3 (the European Union average was 11 in 2007).

I will be curious to see how this all works. Transforming a major city like Chicago in a short amount of time is difficult. Like most American cities, Chicago has sacrificed much for the automobile and even with higher gas prices and more calls for walkable neighborhoods, making quick changes to the transportation grid will require a lot of work. Additionally, traffic safety has a lot of moving parts, such as safety standards for cars, over which Chicago has little control.

I like the comparison to the efforts in Sweden. However, what happens when the target date approaches and the number has not dropped to zero – does someone get blamed, fired, or what? This is a laudable goal but perhaps this could turn into another public war: the war on traffic deaths!

It is hard to argue with safety. However, I imagine someone will raise a question about the possible costs of these measures…what will this war on traffic deaths cost? I also imagine someone could argue that boosting Chicago’s walkability and general pedestrian friendliness would lead to a better quality of life (as well as higher housing values), possibly making Chicago more appealing to younger and older generations who want to live in more urban neighborhoods.

Economy down, traffic congestion down

Posted on by

A company that tracks traffic congestion suggests that congestion was down in a number of metropolitan areas in 2011 because of the economy:

Of the 100 most populous metro areas, 70 saw declines in traffic congestion while just 30 had increases, says Jim Bak, co-author of the 2011 U.S. Traffic Scorecard for Kirkland, Wash.-based INRIX…

Bak says the data show that the reduction in gridlock on the nation’s roads stems from rising fuel prices, lackluster gains in employment and modest increases in highway capacity because of construction projects completed under the federal stimulus program.

In some cases, the connection between job growth and increased congestion was clear. Cities that outpaced the national average of 1.5% growth in employment experienced some of the biggest increases in traffic congestion: Miami, 2.3% employment growth; Tampa, up 3%; and Houston, up 3.2%.

Cities that had big drops in congestion often were those that saw road construction slow considerably from 2010 to 2011 and those where gasoline prices were well above the national average at the peak in April 2011.

Does this fall into the small category of benefits of the economic crisis of recent years?

I would guess many metropolitan residents would be happy with less congestion but I would also guess they wouldn’t like the tradeoff of fewer jobs and higher gas prices. Of course, there have been discussions for years about how higher gas prices would limit driving. But does higher gas prices necessarily have to align with less growth?

Transit-oriented development in the Boston area

Posted on by

Transit-oriented development has been popular for years now and here is an update on this development strategy in the Boston area:

“We see a huge demand around Greater Boston. We’re working in communities from Winchester to Lawrence that are all working to develop vibrant urban villages around public transportation,” Leroux said. “An overwhelming number of people want to live in these types of places, and communities that don’t create them are less competitive for residents and jobs.”

Filling the need in Somerville, where the residential landscape consists mainly of three-decker homes, is Maxwell’s Green, which will feature 184 rental units with amenities to rival many downtown Boston luxury apartment buildings.

Near completion and ready for occupancy this September, the $52.5 million development sits on 5.5 acres and is located minutes from the Red Line stop at Davis Square and adjacent to the much- anticipated MBTA Green Line Extension’s Lowell Street station…

SouthField, one of the largest transit-oriented developments in Greater Boston, is on track for South Weymouth at the former naval air station.

The first phase of the project is already complete, with residents occupying both apartments and townhouses. The total cost of the project, including the homes already built, is targeted at about $2.5 billion, which includes 2,800 homes and 2 million square feet of commercial space.

The “urban village” concept has been around now for several decades. They are thought to be particularly attractive for young professionals who want to live in the suburbs or further away from the city core (partly because of cheaper prices), don’t yet want to buy a home (condos being easier to maintain), want mass transit access, and also want to be in more lively areas with some cultural and dining options.

These types of development are very popular in the Chicago suburbs are well, particularly along the railroad lines that radiate out from Chicago’s center. Many suburbs have sought to build multi-use developments (condos plus offices or small retail establishments) near their commuter train stations. While this means that the residents can access mass transit, it also provides more pedestrians and hopefully customers for the downtown. A number of suburbs have pursued these developments as part of a downtown revitalization strategy.

I would be interested to see how studies about how much these developments reduce traffic and congestion. Particularly in a suburban setting, a couple might be able to go down to one car (or none?) if both use mass transit a lot. However, while mass transit access to the city center might be great, there is often a lack of mass transit options across between suburbs.

I also wonder how much transit-oriented development succeeds because it is seen as trendy.

Why the Washington Metro doesn’t yet reach Tysons Corner

As part of an argument that seems to really be about the difficulties of large-scale bureaucracies in responding to change, Michael Barone explore why the Washington Metro has had difficulty in reaching suburban destinations like Tysons Corner, the prototypical edge city.
