Dynamic road traffic signal control system and method

Abstract

The invention discloses a dynamic road traffic signal control system and method. The system comprises a signal receiving and processing circuit and a signal lamp control and energy source circuit; thesignal receiving and processing circuit comprises a filter capacitor C1, a detection module SIP4, a pin extension and relay module and a 52 single chip microcomputer U1; the single lamp control and energy source circuit comprises multiple signal lamp branches, a light-emitting LED in each signal lamp branch is arranged in a buried signal lamp, and multiple buried signal lamps are buried in various lane lines; a light-emitting LED visible for the one-way coming vehicle is arranged at each of a coming side and a going side of each buried signal lamp; and the driving direction change of one lanecan be realized through three stages including an initial state, a conversion state and an end state. The system serves as the extension of the intersection traffic signal lamp at a road section, theprecision and the flexibility of the road resource distribution are obviously improved; the system is more flexible on the mounting distance and like parameters, and the arrangement way is designed and implemented in accordance with the road condition, thereby sufficiently meeting the demand and solving a specific problem.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a dynamic road traffic signal control system and method. Background technique [0002] With the development of the economy, the number of urban car ownership is increasing day by day. However, due to the late construction of most urban infrastructure in our country and the lack of foresight, the contradiction between cars and road space resources is growing day by day. The most obvious one is traffic jams. When the locomotive is in different working states (idling speed, acceleration, constant speed, deceleration), the impact on traffic emissions is different. When the vehicle is frequently in the deceleration or idling state, the emission will increase. Under traffic jams, cars will frequently be in a deceleration or idling state, so long-term traffic jams have caused an extreme waste of oil and natural gas resources and a huge increase in air pollutant emissions...

AI Technical Summary

Problems solved by technology

[0003] At present, traffic signal devices using wireless communication technology have appeared, such as the "Wireless Traffic Signal Light Management System" disclosed in Chinese Patent Application No. 201811560050.X. The management system focuses on the operation and management of traffic signal lights set at intersections , only optimized from the perspective of construction and technology, there is no direct solution to the problem of low utilization of road space

[0004] Another example is "a light control device for tidal lanes" disclosed in Chinese patent application No. 201811579784.2. Although the light control system described in this patent is buried, it adopts the way of raising and lowering the warning parts to realize the opening and closing of tidal lanes. Closed, due to changes in the depth of the mechanism and the ground space, there is a high construction cost, and there is a possibility of increasing the risk of driving due to new ground obstacles, and it is difficult to use on the roads that have been built.

[0005] The road signal systems described in the above two patents are either based on the traditional road signal system, improve the control combined with real-time data, or use a device with low flexibility for tidal lane guidance. lacking
