Embodiment Construction

[0030] The technical solution will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0031] 1. Traffic data collection

[0032] Investigate the lane division of each entrance lane at the level signalized intersection with short right-turn lanes, the signal cycle, and the green time of each phase t i , red light time r i (i is the phase number); the time U to clear the maximum vehicle queuing length in the short lane; the non-motor vehicle flow V on the non-motor vehicle lane 2 vehicles / h; record and measure the saturated flow rate S of bicycles passing the stop line on non-motorized lanes when there is no interference from right-turning motor vehicles 2 . The minimum time h required for non-motor vehicles to pass through the intersection. (Note: The vehicles mentioned in this example are small cars, and non-motorized vehicles are bicycles of the same size)

[0033] 2. Arrangement of various transportation facilities (see ...

Abstract

The invention discloses a method for releasing right-turn vehicles to pass through a signalized intersection on a short lane under mixed traffic and a control system thereof. The control system comprises a traffic sign marked line, detection equipment, a canalization measure and a signal control facility. The system-based releasing method comprises the following steps of: after the short lane is full of the right-turn vehicles, providing green time for the right-turn vehicles to pass, and stopping releasing straight-going non-motor vehicles on the same side; after the vehicles queuing on the short lane are emptied, releasing the straight-going non-motor vehicles, stopping left-turn vehicles in a left-turn waiting area; and when a detector detects that the short lane is full of the right-turn vehicles, releasing the right-turn vehicles again, and prohibiting the straight-going non-motor vehicles from passing. Through the technical scheme, (1) conflict between motor vehicles and the non-motor vehicles is avoided, and the safety of the intersection is improved; (2) the utilization rate of the green time and the short lane is improved; (3) the delay of the right-turn vehicles and the non-motor vehicles is reduced, and the passing capacity of the intersection is improved; and (4) the traffic management of the intersection is more humanized.

Description

technical field [0001] The invention relates to a method for releasing right-turn vehicles at an intersection and a control system thereof in the field of traffic management and control in traffic engineering. Background technique [0002] In general, there are two ways to let the right-turn motor vehicle flow pass through the traditional level signalized intersection. One is that the right-turn vehicle flow is not controlled by the signal and can pass at any time; Higher, but there are conflicts between right-turning vehicles and straight-going non-motorized vehicles on the same side, and there are many unsafe factors. Another method is to give right-turning vehicles special green light signal phases, so that right-turning vehicles and non-motorized vehicles on the same side can drive separately in time, so as to avoid machine-non-conflict, but this method will make the green light time Lower utilization. One of the above two methods attaches importance to safety but igno...
