Abstract

With agent technology and in view of car-following behavior under the influence of accidents happening on bidirectional four-carriageway expressway, a car-following model based on agent was established. In the description of vehicle agent properties, the quantitative analysis of its separation-desire was carried out according to the data of West China expressway traffic surveys and statistics, the acceleration of vehicle agent was determined by proportional-derivative control theory, the logic intention queue with different accelerations was set up, which made the acceleration response of the model comply with vehicle dynamic features. The model was tested both under specified condition and in random process according to EAD-simulation system. Test result shows that the model can represent the individuality, self-constraint characteristic and self-adaptability of vehicle agent, control its stability by the similar damped character of proportionalderivative control.
