Method for setting crossing self-adapting changeable driveway

Abstract

The invention discloses a method for setting a crossing self-adapting changeable driveway by a computer program, aiming to solve the problem that a single left turning driveway is supersaturated and two left turning driveways are insufficient. The method comprises the following steps: firstly installing a No. 1 triggering detector, a No. 2 triggering detector, a main signal light and a pre-signallight; and utilizing other existing hardware equipment. The method also comprises the following steps: (1) judging the attribute of the changeable driveway, i.e. judging the attribute of the changeable driveway by whether an inequation that N is larger than or equal to N<*> is established or not, wherein N is the continuous periodicity of the time occupancy ratio of the No. 1 triggering detector and the No. 2 triggering detector, which is larger than a critical value, and N<*> is the critical value triggering changeable driveway control; (2) controlling the signal timing scheme optimization ofthe changeable driveway, i.e. (1) controlling the changeable driveway when signal period time is unchangeable, and (2) controlling the changeable driveway when the signal period time is changeable; and (3) setting a pre-signal of the changeable driveway, i.e. (1) changing the attribute of the changeable driveway from straight running to left turning, and (2) changing the changeable driveway fromthe left turning to the straight running.

Description

technical field [0001] The invention relates to a method used in the field of urban intelligent traffic control, more specifically, the invention relates to a method for setting adaptive variable lanes at intersections. Background technique [0002] The left-turn traffic flow at level intersections is an important factor affecting the operation quality of intersections, and the organization of left-turn traffic flow is the difficulty and focus of traffic management. At present, the organization of left-turn traffic flow is mainly to separate it from other traffic flows in time and space. The traditional method is to set up a left-turn special lane, a left-turn special phase, and a left-turn waiting area. At intersections with left-turn special phases and left-turn waiting areas, with the continuous increase of left-turn traffic volume, setting up a left-turn special lane may not be able to meet the needs of left-turn traffic flow, but if Turning to a dedicated lane will ser...
