ABSTRACT
In order to study the influences of trajectory characteristics of vehicles at night in freeway expansion construction areas, day and night observation experiments are conducted to obtain the trajectory offset characteristics based on natural traffic flow. The trajectory characteristics are studied from three aspects: running speed, near road brightness and visual recognition of delineators. It is found that the vehicle trajectory is shifted to the right side and the change in trajectory offset of the passing lane is significantly higher than the traffic lane. It was found that the visual recognition of the delineators affected the vehicle trajectory, the smaller the visual recognition brightness ratio (right side/left side), the larger the lateral shift change of the vehicle. Based on the above research, this study can provide some reference for the improvement and enhancement of safety in the nighttime freeway expansion construction area.
