Abstract
The utility model relates to a self-adapting signal control system based on mixed traffic flow, which comprises a video detection subsystem, a communication network, a computer data-processing subsystem and a signaler, wherein the video detection subsystem and the signaler are connected with the computer data-processing subsystem via the communication network. Compared with the prior art, the utility model has the advantages that the traffic control center can obtain real-time video images of traffic flow at intersections to achieve effective monitoring of urban transport; a camera is used to obtain video signals and a virtual coil is used to replace an induction coil, thus avoiding damage to road surfaces; and information about road traffic, etc, is detected via video signals.
Description
Technical field
The utility model relates to adaptive traffic signal control system, relates in particular to the adaptive traffic signal control system based on mixed traffic flow.
Background technology
The presentization level of traffic is one of important symbol of progress of social civilization.Just how to improve the Modern Traffic operation level, administrative authority is no lack of road improvement infrastructure is arranged, improves the traffic participant traffic behavior and realizes, performs measures such as traffic signals control.The continuous development of urban modernization, the motor vehicle volume of holding continues to increase, and mode of transportation is maked rapid progress, and the urban traffic blocking problem becomes the more and more national urgent problem, and the intersection traffic signal control technology is also had higher requirement.
Some traffic control systems of Chinese city road use at present mainly are to quote the system of external exploitation such as SCOOT, SCAT, and these systems also mainly are the passive-type control system that is based upon based on the road traffic condition basis of motor vehicle, in conjunction with the transport development trend and the special national conditions of China, this also is not suitable for Chinese mixed traffic flow situation.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, the adaptive traffic signal control system of a kind of high-efficiency reliable based on mixed traffic flow to be provided.
The purpose of this utility model can be achieved through the following technical solutions: based on the adaptive traffic signal control system of mixed traffic flow, it is characterized in that, this system comprises vehicle detection subsystem, communication network, computer data processing subsystem, teleseme, and described vehicle detection subsystem, teleseme are connected with the computer data processing subsystem by communication network.
Described vehicle detection subsystem comprises virtual coil module, Video Detection module.
Described communication network comprises fibre circuit or wireless network.
Described teleseme comprises pedestrian's street crossing trigger-type teleseme, multi-period timing teleseme, induction type teleseme or point coordination teleseme.
Application based on the adaptive traffic signal control system of mixed traffic flow is characterized in that this application may further comprise the steps:
(1) the vehicle detection subsystem is gathered the mixed traffic flow data;
(2) the vehicle detection subsystem feeds back to the computer data processing subsystem by communication network with the mixed traffic flow data that collects;
(3) the computer data processing subsystem carries out Treatment Analysis to the mixed traffic flow data that collects;
(4) the computer data processing subsystem is adjusted control to teleseme in real time according to result.
Compared with prior art, advantage of the present invention is that traffic police control center can obtain the access connection traffic flow video image in real time, urban transportation is realized effectively monitoring, utilize camera to obtain vision signal, replace inductive coil with virtual coil, need not destroy the road surface, by information such as video signal detection road traffic flows.
