Recent projections indicate that roadway congestion will increase by perhaps 35% from 1994 to 2013 for the 33 largest metropolitan areas in the U.S. The following options are available to transportation agencies for applications to solve this problem: 1) provide new capacity, 2) induce modal shifts to public transit, and/or 3) improve operational efficiency aspects of transportation infrastructure. Option 3 provides the best opportunity to improve the operational efficiency of U.S. roadways by 'mainstreaming' or allocating funds of regular Federal aid transportation programs for deploying intelligent transport systems (ITSs). The case of Columbus, Ohio, is a good example of a metropolitan area that has been very successful at mainstreaming ITS. Columbus has deployed a computerized traffic signal system covering about 55% of its signals and initiated the first of an 8-phase freeway management system expected to include 100 CCTV cameras, 60 variable message signs, and 330 ramp meters. Other ITS improvements are expected. In order to be included in improvement efforts, the importance of ITS solutions must be made clear at the planning process stage. Enlightenment of the advantages of ITS solutions must be made known to planners and the public alike.
