Driving decision in the car following model is a complex process of reasoning,deciding and executing.There are a lot of vagueness and randomness in knowledge description and reasoning mechanism.Through the analysis of the problem of recent research,the paper has applied cloud model theory to car following model.Based on the description of processing of different decision information and car following pattern,the paper defines the decision variables and concept judging subset and designs experimental methods of model parameter calibration.On the basis of plenty of experimental data,the paper has calculated the membership cloud eigenvalue of related parameters,summarized the reasoning mechanism of car following cloud based on the behavior rules,and finally constructed the car following cloud model(CFCM).
