The invention provides an intersection traffic adaptive control optimization decision method and system based on electronic police data, and relates to the field of intersection traffic signal optimization. Firstly, data integration is carried out based on electronic police data to obtain influence factors such as periodic flow, vehicle types, signal periods and driving behaviors; secondly, a multivariate linear regression model is constructed with the adaptive control effect represented by the traffic capacity as a dependent variable and the four traffic influence factors as independent variables for key factor analysis; and finally, giving out decision suggestions according to the formulated decision standards and analysis results. According to the invention, the evaluation method based on data analysis is introduced to evaluate the self-adaptive control effect to support corresponding decisions, and the data analysis and optimization method based on electronic police data can help optimization personnel to make different decisions for intersections with different characteristics, find out key influence factors of intersection congestion, make targeted optimization, and improve the accuracy of intersection congestion. Therefore, the intersection self-adaptive control effect is improved.
