Reversible-lane-based intersection signal control method

Abstract

The invention discloses a reversible-lane-based intersection signal control method. The method comprises the following steps of, firstly, at eligible intersections, mounting detectors, and laying annunciators, main signal lights, pre-signal lights, reversible lane dynamic signs, wherein the annunciators are provided with computer programs, and the main signal lights, the pre-signal lights and the reversible lane dynamic signs are associated with reversible lanes; secondly, according to historical data, determining approaches where the reversible lanes can be arranged, and starting reversible lane control schemes; thirdly, according to the left turn and straight traffic flow of the approaches and the relation between the number of lanes and the saturation flow, judging the operating directions of the reversible lanes; lastly, according to the directions of the reversible lanes, determining appropriate signal matching schemes. The reversible-lane-based intersection signal control method can improve the traffic capacity of the intersections, reduce delay at the intersections and guarantee vehicle driving safety of the intersections.

Description

technical field [0001] The invention relates to an urban road intersection control method, in particular to an intersection signal control method based on variable lanes. Background technique [0002] The variable lane signal control method is to flexibly control the flow direction based on the information collected by the vehicle detectors installed on the intersection entrance road at different time periods, change the driving direction of the lane, and adjust the original traffic flow according to the variable lane running direction. The signal timing parameters can fully improve the road utilization rate, relieve the traffic pressure at the intersection to the greatest extent and improve the road traffic capacity. [0003] The research on variable lanes in foreign countries started early and is relatively mature. Variable lanes have been listed as a common means of lane management. At present, they have been tried in some cities and achieved good results. However, with ...

Problems solved by technology

But at present, the existing variable lane control is static, and cannot timely and accurately change the direction of the lane through changes in traffic flow, that is, it cannot actively adapt to the current situation of the intersection.
