Who Has The Nation's Worst Traffic?
"The annual Urban Mobility Report, published by the Texas Transportation Institute, this year measures the effect of five congestion remedies in the cities where they are being used. Specifically, the study illustrates the effect of public transportation service and bus and carpool lanes, and three types of roadway operating efficiencies -- traffic signal coordination, freeway incident management (clearing crashes and disabled vehicles) and the use of freeway entrance ramp meters (signals that regulate traffic flow onto the freeway)... Using the national average 25-minute one-way commute trip to work as an example, the researchers found that a combination of all five remedies reduced the total amount of annual congestion delay per commuter from 58 hours to 50.5 hours.... Complete use of the five remedies in all 75 study cities would cut that commute trip delay to 45 hours... Even with widespread use of cost-effective solutions, we need to add more capacity, manage the demand and seek improvements in land development patterns as well."
