[0029] The present invention connects the traffic running state and driving behavior of the conflicting direction, establishes a generalized linear prediction model of straight-left conflicts for four different traffic running states, and proposes a straight-left conflict number of plane signalized intersections based on the traffic conflict prediction model. method of obtaining . The straight-left conflict prediction model established in the present invention under 4 classification situations is based on a large amount of data, and the data inspection of the test group proves that the straight-left conflict prediction model has high prediction accuracy. Saturation is a common indicator to reflect the operation status of signalized intersections. In actual engineering applications, saturation is easy to calculate. It is used as a classification standard and the occurrence rules of straight-left conflicts are different under different operating conditions.
