The new york state department of transportation (nysdot) is tasked with spending approximately $3 billion over the next three years for improvements to new york's transportation system. To carry out these responsibilities, nysdot must have good, reliable travel data on which to base its forecasts and, ultimately, its project and design decisions. Metropolitan area planners have expressed concern aboutthe continued use of travel data gathered in the 1960s as the basisof travel simulation modeling in the 1990s. Because of the high costs, it is unlikely that comprehensive land use, transportation system, and travel surveys will be done in new york state in the 1990s. However, there are valid alternatives which meet regional data needs at lower costs. Nysdot has begun to identify and collect the data necessary for travel forecasting, in addition to its regular monitoring and special data collection activities. New york's approach is to carefully coordinate any new travel survey activities to maximize their utility and to rely on the appropriate sharing and reuse of existing data when and where possible. Indications are that this approach will supply the required planning data to enable nysdot to formulate its capital program for the 1990s and shape the state's long-range transportation plans for the twenty-first century.
