Abstract
The objectives of the study are to model driver's reactive behavior for the information services and mutual behavioral decision processes between vehicles at merging section of urban expressway, to construct integrated evaluation system of traffic flow at merging section by the combination of behavior model and microscopic traffic flow simulation model, and to analyze the effect of information services on the improvement of traffic flow at merging section. Through the simulation, the relation among composition of AHS vehicles, driver's degree of confidence for information contents, and improvement of traffic flow is analyzed.
