Traffic Safety Evaluation of Urban Road Intersection Based on Grey Clustering

For problems on impacting urban road traffic in view of traffic safety conditions of the urban road intersections, the paper evaluated the intersection safety levels by the traffic conflict technique and grey cluster analysis method.The result of the case analysis shows that the evaluation results are close to the actual operating conditions of the intersections.At the same time, it indicates that the method can be more objectively evaluate the safety conditions in the intersections.
