Abstract
Aiming at improving the ancillary facilities of China’s highways, balancing the content and location of traffic sign setting, and decreasing the traffic accident rate, based on the Analytic Hierarchy Process, an evaluation system of highway traffic signs is established. Through site visits and speed measurement on China’s highways, the feasibility of the evaluation model is validated. It was found that this evaluation method not only can reflect the problem of highway traffic sign setting objectively before reconstruction and expansion projects but also can prevent the problems of the design and setting of highway traffic signs and prevent highway operation problems after reconstruction and expansion.
