Washington, DC, tops list of gridlocked US cities

The 2015 urban mobility scorecard for the US, published jointly by the Texas A&M Transportation Institute and Inrix, indicates that urban areas of all sizes are experiencing the challenges seen in the early 2000s and population, jobs and therefore congestion are increasing.

The 2015 urban mobility scorecard for the US, published jointly by the Texas A&M Transportation Institute and 163 Inrix, indicates that urban areas of all sizes are experiencing the challenges seen in the early 2000s and population, jobs and therefore congestion are increasing. The US economy has regained nearly all of the nine million jobs lost during the recession and the total congestion problem is larger than the pre-recession levels.

Cities of all sizes are experiencing the challenges last seen before the start of the recession, meaning increased traffic congestion resulting from growing urban populations and lower fuel prices outpacing the nation’s ability to build infrastructure. The result, the average travel delay per commuter nationwide is more than twice what it was in 1982. For cities of less than 500,000 people, the problem is four times greater than in 1982.

With recent data from the 324 US Department of Transportation showing Americans vehicle miles travelled has surpassed the pre-recession peak in the last 12 months, Scorecard report authors say the US needs more investment in infrastructure to meet demands of population growth and economic expansion.  
 
Scorecard report authors state that road building alone can’t solve congestion problems. Solutions must involve a mix of strategies, combining new construction, better operations, and more public transportation options as well as flexible work schedules.

Some other key highlights from the scorecard include:  Washington, DC tops the list of gridlock-plagued cities, with 82 hours of delay per commuter, followed by Los Angeles (80 hours), San Francisco (78 hours), New York (74 hours), and Boston (64 hours).

Drivers on America’s Top 10 worst roads waste on average 84 hours (or 3.5 days a year) in gridlock, twice the national average.   Of these roads, six are in Los Angeles, two are in New York and the remaining two are in Chicago. Nine other cities have roads ranked in the top 50.

The report concludes that states and cities have been addressing the congestion problems they face with a variety of strategies and more detailed data analysis. Some of the solution lies in identifying congestion that is undesirable – that which significantly diminishes the quality of life and economic productivity – and some lies in using the smart data systems and range of technologies, projects and programs to achieve results and communicate the effects to assure the public that their project dollars are being spent wisely.

    New research from the Accessibility Observatory at the University of Minnesota ranks 46 of the 50 largest (by population) metropolitan areas in the US for accessibility to jobs by transit. The new rankings, part of the Access Across America study begun last year, focus on accessibility, a measure that examines both land use and transportation systems. Accessibility measures how many destinations, such as jobs, can be reached in a given time. In the study, rankings were determined by a weighted average

    Moscow is world’s most gridlocked city, says Inrix
    Moscow is the most gridlocked city in the world, according to a survey of snarl-ups by Inrix. The company’s annual Global Traffic Scorecard found that road users in the Russian capital lost 210 hours last year because of congestion. Inrix weights the data for population, and found that the next four cities on the congestion roll-call were Istanbul, Turkey; Bogota, Colombia; Mexico City; and São Paulo, Brazil. Brazil had another entry on this unwanted list, with Rio de Janeiro in seventh place. Russ

    Car traffic in London is down but congestion is up, says new study
    London Congestion Trends, an in-depth study of the causes of traffic congestion in London between 2012 and 2015 published by Inrix, indicates that congestion in London is increasing, with journey times in Central London growing by 12 per cent annually. Inrix says this is consistent with data that shows that the London economy and population are growing, which normally results in an increase in gridlock. Further, unemployment and fuel prices are down, both of which usually mean a rise in traffic. Despite thi
