The Transportation Equity Act for the 21st Century (TEA-21) created the Value-Pricing Pilot Program, which replaced the Congestion-Pricing Pilot Program in the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). In reauthorizing the program, Congress recognized that value pricing is a new and innovative approach to congestion relief and that much remains to be learned about its effectiveness in different urban settings. Using price to allocate space on congested roads involves charging relatively higher prices for travel during periods of peak demand than in other periods. Faced with these premium charges, travelers would be encouraged to eliminate lower-valued trips, or take them at a different time, or to choose alternative routes or modes. A critically important aspect of value pricing is that while it is reducing the economic waste associated with congestion, it is also generating revenues that can be used to provide benefits to a broad spectrum of road users. Possibilities include funding necessary improvements to the transportation infrastructure, providing improved transportation alternatives, or reducing (or not increasing) other transportation user charges or other local taxes. Three operating pilot projects were launched under the auspices of ISTEA: San Diego, California; Houston, Texas; and Lee County, Florida. In 1995, the first variable-priced and fully automated highway in the United States began operation in Orange County, California. Feasibility studies have been undertaken in several areas, including Los Angeles, San Francisco, and Sonoma County, California; Westchester and Rockingham counties, New York; Boulder, Colorado; Minneapolis, Minnesota; and Portland, Oregon. Pricing projects in Singapore, Norway, France, and Canada illustrate the progress being made in other countries. |
