The invention discloses a regional intersection group safe operation evaluation method based on a complexity theory, and relates to the technical field of traffic safety evaluation. The method comprises the following steps: constructing a regional intersection group comprehensive evaluation index set, and determining a weight coefficient of each index by using an efficacy coefficient method and a multiple linear regression method; and based on the regional intersection group comprehensive evaluation index set and the weight coefficient of each index, calculating a regional intersection group multi-index comprehensive safety intensity value and an intersection area-based accident intensity value, and based on the regional intersection group multi-index comprehensive safety intensity value and the intersection area-based accident intensity value, calculating a regional intersection group multi-index comprehensive safety intensity value. And a five-dimensional evaluation index system is constructed, and the safety level of the intersection is quantized by using quartile. According to the method, the static and dynamic indexes of the intersection are fully considered, so that the influence degree of different indexes on the safety of the intersection is objectively and accurately quantified, and the evaluation is more comprehensive and comprehensive.
