Example Embodiment

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] like figure 1 As shown in the figure, a method for judging intersection delay, the workflow includes 4 parts from front to back: intersection classification and sampling survey, classification and turn-by-turn statistics for intersection turning delay, analysis software for turning identification of all road intersections, and intersection setting Deferred function call index.

[0032] (1) According to the intersection classification and sampling survey, the intersections are divided into 6 categories according to the grade of intersecting roads and the number of lanes:

[0033] The intersection of the main road and the main road, the intersection of the main road and the secondary road, the intersection of the secondary road and the secondary road, the intersection of the main road and the branch road, the intersection of the secondary road and the

Abstract

The invention discloses a method for determining intersection delay. The method includes classified sampling survey on intersections, classifying the intersections according to road level and lane quantities of the intersecting roads, calculating intersection turning delay according to different classification and different turning directions, calculating the average vehicle delay time of an intersection according to the turning of incoming lanes, establishing intersection turning delay punishment functions calculating turning angles for all identified road intersection turning, calling intersection turning delay punishment functions, assigning according to the road types and intersection identified turning, and determining intersection delay according to the intersection turning delay punishment functions. The method can be combined with traffic analysis software and improves intersection delay calculating precision.
