| Abstract: | Traffic conflict technique is a new evaluation method based on non-accident statistics in the traffic safety field.The technique was applied in the consideration of the traffic condition on highway.The ratio between the number of traffic conflicts and the traffic volume in certain road section length was chosen as the index.Traffic conflicts were simulated by software VISSIM.Fuzzy evaluation method was used to evaluate safety condition of Zhaoshangang Tunnel and Xiapu Interchange area in Haosifang direction of highway in Ningbo.The case study indicated that the proposed method had certain advantages compared to traditional evaluation method which was based on accident statistics in highway safety evaluation.The achievements provided reference for the safety evaluation of the similar projects. |
