In this paper, the features of the present traffic safety evaluation methods at signalized intersection at home and abroad are analyzed and the weaknesses of the traditional methods based on accident statistics are revealed. Then, the paper describes a non-accident statistical safety evaluation method, the Traffic Conflict Technique (TCT). Meanwhile, the paper puts forward a safety evaluation method based on Traffic Conflict Technology and gray clustering, which takes three (TC/MPCC) values into consideration, namely that of morning climax, common and evening climax. Finally, the method is applied to five intersections in Beijing as an example and tests the accuracy and feasibility of the model, indicating that it has a better utility value.
