Samenvatting
Car-following behavior is a fundamental factor of capacity bottleneck of ordinary sections such as vertical alignment sag sections. 'Advanced Cruise-Assist Highway System' (AHS) might be calibrated for alleviating the phenomena. Investigation measures of car-following behavior are evaluated: observation from the sky, that from sites, 'test vehicle' measurement and experiment with 'Driver's Surroundings Simulator' (DSS). The reproducibility of car-following behavior by DSS is examined with field test data. Artificial traffic flow, produced by iterative experiments in which an experimental subject follows the leader of the former track of himself with DSS, is investigated. Effects on the flow of car-following behavior are also investigated.
