Car-Following Behavior of Coach Bus Based on Naturalistic Driving Experiments in Urban Roads

摘要

In order to study the car-following behavior of coach bus in urban roads, naturalistic driving experiments were carried out in urban roads. The data of the vehicle itself and the surrounding traffic environment were obtained during the car-following state. Vehicle speed, lane position, vehicle type, relative speed, relative distance were collected. The variation of the car-following distance was analyzed. For the coach bus in urban road, the car-following distance was lognormal distribution. With the increase of the self-vehicle speed, the car-following distance gradually increased and the distribution range of the car-following distance gradually increased. When the leading vehicle was a coach bus, the average car-following distance was 20.00 meters. When the leading vehicle was a passage car, the average car-following distance was 25.77 meters. As the lane position of the vehicle was different, the car-following distance also showed a certain difference.
