Evaluation of Effectiveness of Traffic Signs and Markings of Expressway Service Area Based on Driving Simulator

摘要

As a supporting facility, expressway service area is of great significance to the rapid development of expressway. In order to evaluate the effectiveness of traffic signs and markings of expressway service area from human factor, this paper adopts driving simulator technology. The traffic signs and markings of Shangdian expressway service area of Beijing Xingyan expressway was the research object and the immersive 3D driving simulation scenario was built. Then, the driving simulation experiment was designed based on the way-finding theory. 31 subjects were recruited to participate in the experiment. Finally, based on driving behavior data, the effectiveness of traffic signs and markings in each zone was evaluated. The result shows that longitudinal and lateral deceleration marking, sign and uncolored pavement word, colored pavement word should be set in the entrance zone, diverging area for large vehicle and light-duty vehicle and gas station respectively.
