Special Section on Dynamic Traffic Assignment: A Tool for Evaluating and Assessing Dynamic Traffic Management Schemes

摘要

Intelligent transportation system (ITS) technologies have enabled efficient traffic control. One important issue pertains to extensions of traffic management and data collection schemes over the temporal dimension. For instance, dynamic traffic information extracted from electronic data can improve the spatial concentration of traffic flow, and provide more detailed and accurate origin-destination (OD) information. To discuss the effect of such traffic management measures, we need a model to forecast the time-varying traffic conditions as accurately as possible. Dynamic traffic assignment (DTA) is indispensable for evaluating traffic operations and for planning. In this special issue, we have four articles discussing the use of DTA for implementing and evaluating traffic management schemes, based on ITS technologies.
