Problems solved by technology

For another example, when an emergency or accident occurs in the direction of the "green wave belt" and a congestion point occurs, the entire "green wave belt" will have a phenomenon that the upstream traffic speed of the congestion point is slow, and the traffic flow downstream of the congestion point is small If the signal

Embodiment approach

[0060] The present invention also provides a method for using the system to realize the control of the green wave band of the main road traffic signal based on the Internet of Things. In one embodiment, the method comprises the steps of:

[0061] (1) The signal control center server determines the direction of the traffic signal green wave belt control through the traffic information obtained from the database server, and controls the sequence of intersections according to the signal in this direction, and sets the first group of two consecutive intersections to Set as the current control intersection group;

[0062] (2) The signal control center server obtains the vehicle (C 1 ) pass through the time information of the current control intersection group, and determine the vehicle speed VC of the vehicle passing through the current control intersection group according to the following formula 1 :

[0063] V C 1 = ...

Abstract

The invention relates to system and method for controlling artery green wave traffic signals based on an Internet of Things and belongs to road traffic technical field. The method comprises a signal control central server capable of acquiring vehicle information and flow information of correlative roads in real time from road monitoring systems and database servers which are arranged at various intersections. Thus, by means of the above information, the method may determine speed and time that a current vehicle flow passes two adjacent intersections. Further, the initial time and the duration time of green lights at various intersections in a green wave direction are optimized. Therefore, the setting of the green wave is more real-time and accurate. As a result, various emergent events can be well treated and a road passing efficiency can be greatly increased. The system for controlling artery green wave traffic signals based on an Internet of Things is simple in structure and low in cost. The control method is easy to implement and has a wide application range.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to the technical field of traffic signal control, and specifically refers to an Internet of Things-based main road traffic signal green wave belt control system and control method. Background technique [0002] Traffic problems are an important issue of global concern, and have seriously affected the normal operation of human society and economy. Using the latest scientific and technological achievements to provide various "intelligent transportation systems" that can solve traffic problems are rapidly emerging around the world. For this reason , the signal control method based on agent (agent) and intelligent control technology has become one of the research hotspots. [0003] Ma Yuefeng simulated an agent-based regional traffic signal control system with simulation data, and proposed a multi-agent-based regional traffic signal control system (Ma Yuefeng, Research on a multi-a...
