Modifying Simulation Model under Mixed Traffic Condition

Traffic simulation technology is a practical computer simulation technology, and the development of traffic simulation software systems are usually based on the knowledge of computer and traffic. Aiming at the situation of china, an improved approach of the traffic simulation is proposed in this paper. Under the special condition in China, the mixed traffic whose lanes are not divided clearly is chaotic. Without clear state of car-following or lane-changing, and also influenced by the speed of the non-motor vehicles ahead, the gap between vehicles, as well as the angle between the gap and current vehicles, the speed and the angle of the vehicles in motion will change real-timely. Based on the research done before, the mixed traffic advance model is put forward in this paper on the basis of the stimulation-action model. It is demonstrated through example that the traffic state in China under the condition that the traffic lanes are not divided clearly is simulated by using the proposed model more accurately, thereby, it presents a new idea for related research.
