N2 - This paper presents an integrated dynamic simulation-assignment model, DynaTAIWAN, for Advanced Traffic Management Systems as well as Advanced Traveller Information Systems. The model is composed of two layers, namely simulation-layer and real-time control layer. The simulation is designed to simulate traffic flow patterns according to assumed tripmaker characteristics and/or under a set of given conditions; the real-time control layer receives real-time vehicle information and forecast short-term traffic flow patterns. Four different vehicle types are explicitly considered and modeled in DynaTAIWAN, including car, bus, motorcycle, and truck. Car, trucks, and bus are represented by passenger-car equivalent (PCE) in DynaTAIWAN. Motorcycles are moving along the link through macroscopic flow relationships, and the speed of motorcycles are adjusted to reflect motorcycle characteristics. At intersections, motorcycles are moved according to the sequence of left-turn-waiting section, waiting section, and normal traffic lane. Numerical experiments are conducted in a 50-node test network and a Taichung City Network to explore the dynamic model under real-time information supply strategies.
