Embodiment Construction

[0014] Step 1 When the vehicle is driving, the vehicle-mounted radio frequency module fixedly installed in the vehicle transmits wireless signals in the form of broadcasting according to the current driving intention of the vehicle.

[0015] Step2 is attached figure 2 As shown here, taking the intersection as an example, several roadside RF receiving module devices are installed on each side of the road, and the interval between adjacent devices is 8 meters.

[0016] Step3 The roadside radio frequency receiving module receives the wireless signal sent by the vehicle radio frequency module.

[0017] Step4 is attached image 3 As shown, when a certain vehicle is driving towards the traffic light, two adjacent roadside RF receiving modules on the right side of the vehicle successively receive the signals sent by the vehicle-mounted RF module (received in the order of k1, k2, k3, etc.), that is, to judge For a vehicle is entering the traffic light area; when the vehicle passes ...

Abstract

The invention discloses a control system and a control method for dynamic adjusting of traffic light time. The control system comprises a vehicle radio frequency module, a roadside radiofrequency receiving module, a roadside communication module and a traffic light control module. The control method comprises steps that: under a real traffic condition at a specific crossing, a wireless signal is transmitted by the vehicle radio frequency module in a broadcast mode according to driving intention of a vehicle; specific crossing information is increased after the wireless signal is received by the roadside radiofrequency receiving module, and is transmitted to the roadside communication module in a data frame mode; after the number of vehicles at the specific crossing in all directions is collected by the roadside communication module, vehicle flow information is transmitted to the traffic light control module; whether traffic light time duration needs dynamic adjustment is determined by the traffic light control module according to set control strategies, and thereby dynamic adjustment of the traffic light time is realized, and a traffic obstruction state under a abnormal traffic flow state is alleviated.

Description

technical field [0001] The invention relates to the field of traffic signal control, in particular to a control system and a control method for dynamically adjusting the time of traffic lights. Background technique [0002] In recent years, with the rapid development of my country's economy, the number of domestic automobiles has continued to increase, and urban traffic congestion has become increasingly serious. However, the existing traffic light time is basically a fixed setting, which cannot be intelligently adjusted according to actual road conditions, and cannot effectively alleviate traffic congestion. [0003] In order to solve the above problems, various traffic light control devices or systems have appeared. For example, the Chinese patent "A Novel Intelligent Traffic Light Control System" whose patent application number is 200610022581.4 is mainly composed of a camera module, an identifier, a server and a traffic light controller connected in series. The recogni...
