Stated Choice: A New Tool for Transportation Demand Forecasting

摘要

Federal and state highway congestion and clean air statutes look to transportation demand management (TDM) for solutions. TDM policies range from mode shift strategies and departure/ arrival time strategies, to strategies that alter the length of the work week and distribute work tasks to sites other than the conventional work location. Most of the strategies are relatively new and untested. Professionally certified look-Up tables and nomographs that show change in car ridership (analogous to ITE's Trip Generation) do not exist. Rough estimates of the effectiveness of parking management or rideshare incentive programs can be derived from case studies. However, many unique conditions surround the individual sites where the original data was taken; consequently transfer of these models to other sites is problematic.
