Good news about Chicago traffic and congestion – but due to new criteria

Posted on by

A new report from a group named CEOs for Cities claims that Chicagoans spend the least amount of time in rush-hour traffic compared to other major cities:

The report’s ranking of mobility in 51 cities found that Chicago-area residents spend the least time in rush-hour travel. In Chicago and some of the other best-performing cities — including New Orleans, New York, Portland, Ore., and Sacramento, Calif. — commuters typically spend 40 fewer hours a year in peak-hour travel than the average American, the report said.

In metro areas with the worst urban sprawl — including Nashville, Detroit, Indianapolis and Raleigh, N.C. — residents spend as much as 240 hours per year in rush-period travel on average because commuting distances are much longer, said the report, which was produced with the support of the Rockefeller Foundation.

This seems to be contrary to other studies I’ve seen that suggest Chicago is quite congested. One reason this study might have different results is a new criteria in the methodology.

The report’s author criticized other mobility studies that focus on the amount of traffic congestion in a region without factoring in travel distance.

The Urban Mobility Report, issued every two years by the Texas Transportation Institute, is regarded by many experts as the authoritative voice on traffic congestion issues. The report consistently ranks the Chicago region as the second or third most-congested area of the nation. It does not account for travel distance.

I am left wondering whether travel distance an important factor to include…

Comparing male and female drivers

A recent study by New York City shed some light on gender differences in driving and traffic behavior:

80 percent of all crashes in a five-year period in which pedestrians were seriously injured or killed involved men who were driving. The imbalance is far too great to be explained away by the predominance of men among bus, livery, taxi and delivery drivers, said Seth Solomonow, a spokesman for the city’s Transportation Department…

The males of the species are not only more dangerous as drivers, they are more likely to be hurt while walking, the city’s study found. More men than women were killed or injured as pedestrians in every age group except among those over 64 (perhaps because women live longer and were overrepresented). Boys 5 to 17 years old ranked first in the absolute number of pedestrian deaths and serious injuries, with 785, more than twice the number of girls in that age range, though elderly people were more vulnerable as a share of the population.

The article suggests that boys and girls learn these behaviors at a young age: boys think it is okay to be more aggressive around the street.

So where exactly do boys pick up this information? From their fathers/role models, the media, watching people drive or walk around? This socialization process would an intriguing one to delve into.

Minneapolis and Seattle fight congestion

USA Today reports on successful efforts in Minneapolis and Seattle to cut down on congestion on local highways. Some of the efforts include: building more bus lanes, building more light rail, encouraging employers to have flexible schedules, variable speed limits depending on traffic, high-occupancy vehicle lanes, and more.

And you thought your commute was bad

Wired writes about a report released by IBM Research regarding traffic in large cities. Using a web-based survey, IBM  included 8,192 drivers in 20 cities. IBM developed a “Commuter Pain Index” that is comprised of ten criteria.

The worst cities, starting with the worst and then declining on the index: Beijing, Mexico City, Johannesburg, Moscow, and New Delhi. The first US city, Los Angeles, shows up at #14 with New York and Houston at #17 and #18, respectively.

If you were curious, IBM recommends as a solution new technologies to “empower transportation officials to better understand and proactively manage the flow of traffic.”

Combining stop and yield signs

Posted on by

A venture capitalist is seeking a new road sign: a combination of the stop and yield signs. His reasoning: there are times when no one else is at the intersection and a driver should not have to completely stop. These combination signs would save much time and money and would function best when a minor road intersects a major road. Read about it here (and also get a lesson in when stop and yield signs were developed in America).
