Abstract
For analysis of influence on traffic environment change, a traffic simulation model is used. In the study, the carfollowing model that is the important component of the traffic simulation is examined. In the ordinary traffic simulation model, a numerical formula model is used as a car-following model. In the study, the applicability of the fuzzy neural network model is examined. In the existing study, the fuzzy neural network model is developed using the running survey data. In the study, the applicability of the car-following model is examined. As a result, the model using the fuzzy neural network can be estimated in a small error then a conventional non-linear car-following model. As s result of examination using the traffic simulation model, the difference of the result by the model is observed.
