NEEDS FOR DEVELOPPING NEW CAR-FOLLOWINGMODEL FOR EVALUATING CRUISE-ASSISTHIGWAY SYSTEMS

摘要

With implementation of a newly developed 'Cruise-Assist Highway System', one majorimpact would be replacement of normal (no-assistance) vehicle with vehicle instrumentedwith assistance-device. Secondly, the influence of behaviour of vehicle instrumented ondriving behaviours of normal vehicles around the one should also be examined. To evaluatethese two kinds of impact, driving behaviour models for normal vehicles, used in trafficsimulation, must be established. There are many existing car-following models, but theycannot describe real traffic such as capacity bottleneck phenomena occurred at sag sectionsand/or tunnel entrances. This study reveals the model structure that could describe such trafficphenomena, and the method to evaluate the parameters of the model.
