Dynamic vehicle dispatching and routing strategies are important aspects of Commercial Vehicle Operations (CVO) applications of Intelligent Transportation Systems (ITS) technologies. One of the primary operational benefits of real-time information on vehicle locations and demands is the ability to dynamically assign vehicles to time-sensitive demands, or to efficiently re-route vehicles according to current traffic conditions. This paper aims at developing evaluation framework in which dispatching and routing operations could be tested as individual vehicles in a realistic traffic simulation environment. The simulation-assignment model, DYNASMART, is applied to evaluate dispatching and routing strategies in a traffic network. Numerical experiments are conducted in a Taichung City Network to investigate dynamic vehicle dispatching and routing strategies under real-time information supply strategies, and to assess the effectiveness of such strategies in a dynamic perspective.
