Dynamic traffic assignment model considering the effects of traffic management

This paper firstly analyzes the effects of traffic management on dynamic traffic properties. Then focused on signal control and management, the dynamic user optimal (DUO) model considering intersection signal control (ISC) is discussed and proposed in this paper. And aiming at this new model, we also issued the disadvantages of the model such as its unreasonable simplification to intersection signal control mode. So we proposed the improved scheme, which is to transfer the ISC mode into a series of virtual links and to integrate these links into the whole links. This method can solve the question of simulation of ISC well and easily. At last the application foreground of this model such as to discuss the effects of signal control management on the whole traffic network, to analysis traffic capacity and queue length of link at the intersection and assess them with this model is discussed in this paper.
