The Research Of Urban Vehicles Based On Simulation With AIMSUN

When we study on the simulation research of flows which to the transportation, the model is the foundation of simulation and the simulation is the realization. The modeling and the simulation which to the transportation flows are the main content in this article, the main works as the follows:First of all, the structure of the microscopic transportation simulation model system is established, which is based on analyzing the actual situation and the character of intersection. This structure is constructed from some model parts, such as the generation of vehicles,the layout of inter section,the description and travel paths of vehicles,the delays of vehicle in the signal intersection,the control and management of transportation.Second, the programming of software is given in the article which is based the simulation system, for the more bringing forward the control measures of urban intersection.Finally, the models based on AIMSUN (advanced interactive microscopic simulator for urban and non-urban networks) are established .The first experiment: the vehicles of intersection are simulated which are based on the model of microscopic simulation and the control management of transportation. The control plans are optimized through designing the control managements of intersection,modeling geometry characteristic of the path,establishing parameters of vehicle,devising the function of traffic lane. The second experiment: emphases the driving process which is based on the O-D matrix and path selected. When there is a traffic accident happened on path A, we choose the path B instead of path A contritely to arrive the destination.
