Embodiment Construction

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

[0031] Such as figure 1 As shown, a method for judging delays at intersections, the workflow includes 4 parts from front to back: classification and sampling survey of intersections, classification and turning statistics of intersection turning delays, turning recognition of all road intersections in the analysis software, setting intersections Deferred function call index.

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

[0033] Intersection of trunk road and trunk road, intersection of trunk road and secondary trunk road, intersection of secondary trunk road and secondary trunk road, intersection of trunk road and branch road, intersection of secondary trunk road and branch road, intersection of branch r...

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.

Description

technical field [0001] The invention relates to a method for judging delay at an intersection. Background technique [0002] Intersection delay is an important constraint for travel route selection. In current traffic analysis, traffic surveys are generally carried out on important intersections in the urban road network, and the average delay time of vehicles at the intersections is counted, and entered into the analysis software to participate in relevant calculations . Due to the cumbersome manual setting process of intersection delays and limited data information in the database, the accuracy of traffic modeling is low and the modeling efficiency is low. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a method for judging delay at an intersection, which can be closely combined with traffic analysis software, and improves the calculation accuracy of delay at an intersection. [0004] In order to achieve the above...
