“…This paper has presented a new approach to the empirical study of the evaluation of traffic safety facilities. The proposed evaluation method provided not only the overall system performance but also the most significant factors which affect the system performance; these basic findings are consistent with the results in previous similar reports [11], [16] and [25].…”

“…Koscianski et al constructed an indicator system based on the comprehensive analysis of problems associated with traffic safety facilities and determined an evaluation method based on the analytic hierarchy process (AHP) [5][6][7][8][9]. Wang and Yao et al used the fuzzy comprehensive evaluation method and set pair analysis to solve some ambiguous problems and applied three major tools of fuzzy theory in the evaluation of complex traffic safety facilities [10][11][12][13].…”

More and more connected and autonomous vehicle (CAV) open test roads reconstructed on the basis of traditional roads have appeared in China. However, the management policies vary, which makes the traffic environment complicated. This paper takes CAV test road safety management as the research aim and investigates the open test condition through the evaluation of the traffic safety facilities. Indicators were rigorously screened, then the game theory model was used to determine the combination weight of the indicators, and the set pair analysis was applied to solve the uncertain problems. A case study for the CAV test road network of a city in central China was implemented and the results show, regarding the traffic safety facilities’ condition, among the 20 sections of the city’s CAV test road network, 15% of which are at an excellent level, 75% of which are at a good level and 10% of which are at a moderate level; road signs, guardrail facilities, isolation facilities and road features are the main limiting factors affecting the level of traffic safety facilities. Based on the results, recommendations have been made for the transport management authorities in the aspects of safety management policy-making and facilities maintenance.
