For years now, The Urban Mobility Report, issued every two years by the Texas Transportation Institute, has been regarded by many transportation and urban planning experts as the ‘bible’ on traffic congestion issues. The report has been used to justify large road improvement projects throughout the country in an attempt to solve major metropolitan traffic congestion problems.
However, a new report from CEOs for Cities offers a dramatic critique of the 25 year old industry standard created by the Texas Transportation Institute’s Urban Mobility Report (UMR). The report provides a new look at traffic congestion and suggests there are additional reasons why Americans spend so much time in traffic. The report
The new report titled Driven Apart: How sprawl is lengthening our commutes and why misleading mobility measures are making things worse says the solution to the congestion problem has much more to do with how we build our cities than how we build our roads. The report says that we need new metrics like 'total trip distance’ and ‘total travel time’, metrics that are not currently in the The Urban Mobility Report.
The report ranks how long residents in the nation’s largest 51 metropolitan areas spend in peak hour traffic, and in some cases the rankings are almost the opposite of those listed in the 2009
Urban Mobility Report. Here’s a list from the report of the 10 cities (out of the 51 studied) where commuters spend the most time getting to work every day.
|Cities||Avg. hours per year in traffic|
|Detroit – Warren – Livonia||179|
|Indianapolis – Carmel||166|
|Louisville / Jefferson County||165|
|Raleigh – Cary||161|
|Birmingham – Hoover||159|
The report says that compact cities are the real answer to reducing traffic delays. The key is to have land use patterns and transportation systems that enable their residents to take
shorter trips and minimize the burden of peak hour travel. These conclusions are very different than those of the UMR, which has long been used to measure traffic congestion and has been used to justify road improvement projects costing millions of dollars.
It’s nice to have a fresh look at the traffic congestion issue. Thanks CEO for Cities!
