To solve the problem of identifying black spots in intersections, this paper first comprehensively analyzes the current domestic identification methods of black spots. Based on the literature review, the concept of black spots is redefined by considering the actual situation of city roads. Then an identification method of black spots in intersections of city roadways based on a traffic conflict technique is presented and demonstrated. The paper ascertains the Poisson distribution of traffic flow by comparing various models of traffic flow. Finally, this paper constructs the identification model of black spots in intersections, introduces the ratio of traffic conflict and mixed passenger car units (TC/MPCU) as an index, and draws up the identification standards. Thus, the identification method of black spots in intersections of city roadways is proposed based on the traffic conflict technique. Through validation, this method could fairly represent the actual safety conditions of city roads by using the collected data.
