Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0015] As shown in the figure, a signal control system and method for solving intersection congestion, a signal light 2 is set at the intersection, a signal control machine 1 with a coil detection module is set on the sidewalk of the intersection, and a signal light 2 is set upstream or downstream of the intersection or upstream and downstream , a vehicle detection coil 3 for detecting a vehicle congestion state is arranged downstream of the intersection.

[0016] Both the vehicle detection coil 3 and the signal lamp 2 are connected with the signal control machine 1 and work in linkage under the control of the signal control machine 1 .

[0017] The vehicle detection coil 3 is arranged on each lane downstream of the intersection, and each lane is arranged with 2 front and back. The coil closest to the pedestrian crossing line is about 5 meters away from the pe...

Abstract

The invention discloses a signal control system for solving intersection congestion and a control method thereof. The signal control system for solving the intersection congestion and the control method thereof are characterized in that a detecting coil which obtains a traffic congestion state through detecting vehicle queue length is arranged on down stream of an intersection, and a signal control machine switches phases of a signal light through the traffic congestion state detected by the detecting coil. The signal control system for solving the intersection congestion and the control method thereof have the advantages that under the circumstance that traffic police enforcement does not exist, the intersection congestion under the circumstance of a green light, namely, going through the green light is solved through automatic detecting control of the signal control machine, the intersection through efficiency is improved, the working strength of on-site guidance for a traffic policeman is reduced, and the technical management level is improved.

Description

technical field [0001] The invention relates to the field of road traffic management, in particular to a signal control system and a control method for solving intersection congestion. Background technique [0002] In recent years, with the rapid development of my country's economic construction, the car ownership has shown a double-digit growth trend, while the road traffic construction is far behind the speed of vehicle development, resulting in a serious shortage of traffic resources, making occasional traffic jams become commonplace. Frequent traffic congestion, the entire road network is at a low service level. [0003] Intersection traffic is a turbulent area of ​​two-way traffic, and it is a more prominent contradiction and conflict point in traffic management. Whether the phase setting of intersection signal controller is reasonable or not directly determines the efficiency of intersection traffic. Usually, the signal controller adopts time control (according to the...
