Full-induction type comprehensive vehicle waiting control method

Abstract

Provided is a full-induction type comprehensive vehicle waiting control method, which is targeted for a cross intersection, entrance lanes and exit lands of which cannot be expanded, and is characterized by carrying out traffic operation organization by utilizing 2 main signal phases, 4 pre-signal phases and 2 pedestrian phases, establishing two kinds of alternative phase display orders, summarizing 6 green light time distribution principles, arranging a near-end detector and a far-end detector for each lane in the upstream of a main signal stop line in each entrance direction, collecting time headway data in real time, managing green light time of the pre-signal phases according to judgment results of five traffic incidents and managing green light time of the main signal phases according to the judgment results of the five traffic incidents. The method can help drivers understand instructions of traffic control facilities correctly, makes full use of pass space resources of a comprehensive vehicle waiting area, and gives a quick response to dynamic changes of pass demands of motor vehicles, thereby facilitating eliminating traffic accident hidden troubles and improving pass efficiency of the intersection.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic control, and relates to a full-sensing comprehensive waiting control method. Background technique [0002] Inside signalized intersections, motor vehicles turning left in any direction of entry form a large number of traffic conflict points with other road users. In order to cope with the traffic volume of left-turn motor vehicles with medium and high loads, it is usually required to widen the entrance and exit lanes of signalized intersections, and set up special left-turn entrance lanes to realize the traffic between the upstream road section and the entrance road, and the entrance road and the exit road Matching service capabilities, adopting the phase display order to protect left turns, safely manage traffic conflicts, and efficiently serve traffic demands. [0003] The road land in urban built-up areas is tight, and some signal-controlled intersections cannot widen the entrance ...

AI Technical Summary

Problems solved by technology

[0012] (1) During the period when the comprehensive waiting control is enabled, it is difficult for the driver to correctly understand the instructions of the traffic control facilities. If the on-site command of the police on duty is not used, it is easy to frequently make wrong driving behaviors and destroy the cooperative working mechanism of the pre-signal lights and the main signal lights. , there are certain hidden dangers of traffic accidents;

[0013] (2) During the period when the integrated waiting area is enabled, the fixed signal timing cannot effectively resolve the contradiction between the fixed length of the integrated waiting area and the dynamically changing traffic demand of motor vehicles. There is a phenomenon of waste or shortage of passing space and time resources, which reduces the efficiency of crossing traffic;

[0014] (3) During the period when the comprehensive waiting control is enabled, the fixed signal timing cannot dynamically adjust the time difference between the green light end of the pre-signal light and the downstream main signal light according to the traffic operating conditions in the comprehensive waiting area. Incompletely clearing vehicles in the comprehensive waiting area or taking too long to clear vehicles, there are certain hidden dangers of traffic accidents, and the efficiency of intersection traffic is reduced
