Traffic signal management is one of the most cost-effective ways to keep traffic moving smoothly and to make streets safer. Efficient traffic signal control systems improve air quality and reduce fuel consumption, reduce traffic congestion, reduce the number of crashes, reduce red-light running, and postpone or eliminate the need to construct additional road capacity.

Studying all relevant information, including the lessons learned from previous Olympic Games, the Utah Department of Transportation (UDOT) created and implemented an effective travel demand program to handle the anticipated increase in traffic during the Winter Olympics in February 2002. UDOT's goals are to get the athletes and spectators to Olympic venues in an efficient and timely manner and to reduce background traffic by 20 percent.

The collection of Carl Rakeman's 109 original paintings documenting the history of highway transportation in America finds a new home at the Texas Transportation Institute. From 1921 to 1952, Rakeman painted this extraordinary pictorial record of the development of travel in this nation. These paintings cover American travel from frontier Indian trails and pre-colonial times to modern highways.

It may be surprising to some, but even Nevada with its desert climate has wetlands. The Federal Highway Administration (FHWA) and the Nevada Department of Transportation created a large wetlands area adjacent to the scenic Washoe Lake to offset the unavoidable loss of wetlands areas as a result of highway construction and maintenance projects in and around Reno and Carson City.

The Maricopa County (Ariz.) Department of Transportation in Phoenix has put in place a program that makes contractors on roadway paving projects put their money where the ride is. Contractors, under this incentive program, can earn as much as an additional 10 percent of total paving costs in incentive bonuses by exceeding the preset standard for smoothness. Conversely, contractors are hit in the pocketbook if they don't meet the standard.
