Abstract:
The invention relates to a traffic signal mode field, discloses a method for a greenwave mode of traffic signal control that can relieve jammed traffic in 2 cross directions in a roadnet, the control method comprises the following steps: 1) calculating and allocating of RATIO mode with obtaining the jammed vehicle queue start-time of road-segments; 2) calculating and allocating of the 2D-Jam-Relief greenwave time-offset; run RATIO after the 2D-Jam-Relief greenwave time-offset runs out. The present invention shows that 2D-Jam-Relief greenwave signals mode obtains higher efficient by 50% in relieving heavy traffic jam in a roadnet than 1D-Jam-Relief greenwave mode, by 100% than mode RATIO, greatly improve the efficiency of traffic signal control and traffic.

Claim (Index 1):
A method for 2-cross-direction traffic jam-relief greenwave in roadnets includes steps:\n S1: Initialize signal system as mode RATIO with obtaining the feature parameters of a controlled roadnet, such as a rectangle area of M*N intersections, M columns of D-channels, N rows of D-channels, and the start-time of the jam-vehicle-queues of the road-segments of the D-channels of roadnet, denoted by JVQ-start-time, where the JVQ-start-time equals to JVQ-start-coefficient*queue-length, wherein the JVQ-start-coefficient ranges from 0.14 to 0.22, taking median 0.18, unit: sec/meter, can be dynamically adjustable with the control system; S2: calculate and configure 2D-Jam-Relief greenwave time-offset for every intersections: 1) setup an origin source-intersection of 2D-Jam-Relief greenwave, which is an influx point of 2 cross jammed traffic direction ends, that's, an intersection at a corner of the rectangle area, set one of the 2 directions as master controlled direction and the other as slave controlled direction, their respective reverse directions as master traffic Jam-Relief greenwave direction and slave traffic Jam-Relief direction, meanwhile, set all the source-intersections of the Jam-Relief greenwave of master D-channels in the rectangle area as slave Jam-Relief greenwave time-offset D-channel, that's, a D-channel at the edge in the rectangle area, 2) calculate Jam-Relief greenwave time-offset of every intersection of every master D-channel: the sum of the JVQ-start-time of the road-segments between a source-intersection and one of its downstream intersections as so-called intersection jam-relief greenwave-offset of the downstream intersection in every master jam-relief greenwave D-channel in the rectangle, 3) calculate slave Jam-Relief greenwave time-offset of every intersections in the slave jam-relief greenwave time-offset channel: the sum of the JVQ-start-time of the road-segments between the origin source-intersection and one of its downstream intersections, the source-intersections of master greenwave D-channel along the slave Jam-Relief greenwave direction, 4) add respectively corresponding master/slave two time-offset and set up for every intersection: add its master jam-relief greenwave time-offset in its master channel and its slave jam-relief greenwave time-offset at the source-intersection of its master channel referring to the 2D origin source-intersection along the slave direction; S3: run RATIO mode after running out respective 2D-Jam-Relief greenwave-offset of an intersection with red light on or without signals.
