URBAN TRIP DISTRIBUTION IN PRACTICE .2. QUICK RESPONSE AND SPECIAL TOPICS

The companion paper reviewed the state of the art of conventional analysis of urban passenger trip distribution. This part reviews the status of quick-response analysis and special topics. The quick-response analysis includes the National Cooperative Highway Research Program (NCHRP) simplified techniques, traffic-count-based models, a self-calibrating gravity model, partial matrix techniques, heuristic methods, and facility forecasting techniques. The microcomputer implementation of quick-response techniques is addressed. These quick-response methods may require a partial or no base-year trip matrix and they may be applicable to only base-year analysis or to forecasting too. The special topics include geographic information system (GIS) applications, use of census data, freeway trip distribution, pedestrian trip distribution, other trip-distribution models, and theoretical features. These papers are part of a series being produced by the Planning Committee of the Urban Transportation Division (UTD) of ASCE. By summarizing the current status of trip distribution, the Planning Committee hopes to raise awareness and understanding of available analysis tools and to help their applications and development.
