Embodiment Construction

[0020] Aiming at the distribution of traffic flow at intersections of typical urban multi-lane two-way traffic, the present invention adopts an optimization control method for dynamic traffic flow, implements the algorithm in the DSP development environment CCS, and transplants the optimization algorithm into the DSP system to realize single The self-adaptive optimization control of the intersection adopts high-performance floating-point DSP as the core processor chip of the system, and designs a main control board based on this chip. The communication interface between each bus communication interface module and the main control board is designed according to a unified standard . Combined with the LonWorks bus communication module, the data communication between the modules of the signal machine and with external devices is realized; the Neuron neuron chip is used as the core, and the field bus topology is used for networking, which enhances the stability and reliability of da...

Abstract

A single-intersection traffic signal optimization control method is characterized in that a traffic signal control system is established which includes a main control board, a vehicle flow detection and processing module, and an output drive and green conflict detection module; the vehicle flow detection and processing module collects in real time vehicle flow and queuing length information of all directions of an intersection and transmits to the main control board; the main control board calculates an appropriate timing plan in real time according to the vehicle flow and queuing length information of all directions of the intersection, and sends to the output drive and green conflict detection module; and the output drive and green conflict detection module controls light color changes of signal lamps according to the timing plan.

Description

technical field [0001] The invention relates to a traffic signal control method at an urban single intersection, which belongs to an optimization control method based on adaptive dynamic programming. Background technique [0002] With the development and popularization of computer technology, the urban traffic signal control system with computer as the core has been developed rapidly and widely used in many cities. Such as SCOOT system, SCATS system, etc. These systems have played a certain role in reducing traffic delays and maintaining traffic safety at intersections. However, in addition to the high cost of these systems, there are still some shortcomings, such as: there is no real-time traffic model, but the signal control parameters are selected from the established scheme, which limits the degree of optimization of the control parameters; when the phase difference scheme is selected, there is no real-time traffic flow information Feedback, low reliability; undetectab...
