Research on Influencing Spreading Model of Road Congestion Based on Traffic Flow and Cellular Automata Approaches

The quantifying model of influences from urban road traffic accidents is built in this paper, in order to research influencing coverage and effects from road traffic accidents; and the reasonable evaluation indexes are adopted based on the model to quantify influencing coverage and effects from road traffic accidents and determine related factors with influencing coverage and effects from road traffic accidents, also the model is contrasted and verified by actual cases; it is shown from the results that the queue length, traffic recovery time and travel time error are in compliance with the requirements, indicating that the simulation results of this model is feasible and effective, with a certain reliability, and provides a theoretical basis for the evaluation of the effectiveness of traffic emergency measures and implementation of traffic control.
