The invention relates to a traffic control system, in particular relating to an intelligent urban traffic control system which consists of a vehicle navigator user terminal and a navigation center control end, wherein the navigation center control end comprises an intersection capturing recognition device, an optical transceiver, an optical transceiver cabinet, a control terminal and a display interrupt device; the vehicle navigator user terminal comprises a GPS (global positioning system) positioning device, a navigation control device, a downloading storage and a user terminal; the navigation control device is connected with the GPS positioning device, the user terminal and the downloading storage respectively; and the vehicle navigator user terminal is connected with the navigation center control end by a data transmission device. Compared with the prior art, the intelligent urban traffic control system has the following characteristics: all vehicles can know the speed and congestion conditions of all roads in real time, a vehicle-mounted GPS navigation system can select an optimal path according to the congestion conditions.
Description
Technical field
The present invention relates to a kind of traffic control system, particularly a kind of intellectual urban traffic control system.
Background technology
Along with the development of modern society, people more and more pay attention to urban transportation, public safety and environmental protection, have proposed the notion of City Green traffic aisle.So-called City Green traffic aisle, claim green wave band again, be meant by improving the integrated management ability of the urban transportation overall situation, increase substantially urban transportation efficient, avoid occurring the urban transportation bottleneck, realize the traffic safety accident free, reduce city vehicle exhaust emissions amount and noise, thereby reduce environmental pollution and the consumption of earth resources.Present urban traffic control system generally comprises control management system and is arranged on the actuating unit of traffic intersection, as junction machine, traffic signaling equipment etc., employing be to concentrate or the method for collecting and distributing control, when traffic zone increases, also need the configuring area controller.Its course of work is: control management system is passed through the reckoning to judgement, signal period, split and the relevant crossing signal phase difference of each highway section day part traffic flow information, adjust the solution of each crossing signal timing dial, carry out the control of the oral sex ventilating signal lamp that satisfies the need then by junction machine.But, because existing urban traffic control system is the method that adopts centralized control or collecting and distributing control, its adjustment process level to the control and management scheme at each crossing is many, efficient is low, deviation is big, the coordination ability deficiency of crossing local traffic and city overall situation traffic, and the crossing is adjusted successively by serial mode one by one, can not realize parallel processing, therefore, the efficiency of management and managerial ability are lower, be unfavorable for the traffic administration in the big regional extent, can not adapt to complicated traffic, often need the traffic police to come to the operation of a plurality of highway section manual intervention urban traffic signal management systems personally, can't satisfy the requirement that realizes the City Green traffic aisle.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of intellectual urban traffic control system.This intellectual urban traffic control system can send to vehicle user to the congestion of road, when the driver after being provided with the destination in the GPS navigation system, navigational system also can be according to the jam situation of road, selects best enforcement route intelligently.
For solving the problems of the technologies described above, described intellectual urban traffic control system, be made up of automobile navigation device user side and navigation center's control end, it is characterized in that: described navigation center control end comprises each crossing candid photograph recognition device that is installed in urban traffic network, capture the fiber optic that recognition device is connected and is responsible for opto-electronic conversion and light emission and light-receiving with described crossing, collect the fiber optic cabinet of the photosignal of above-mentioned all fiber optics, and be used for capturing recognition device to described crossing during by the crossing and send the control terminal of capturing instruction and reading the data of capturing identification equipment and show and interrupt at vehicle; Described automobile navigation device user side is made up of GPS locating device, Navigation Control Unit, download memory and user terminal, and described Navigation Control Unit is connected with described GPS locating device, user terminal, download memory respectively; Described automobile navigation device user side is connected by data link with the navigation center control end.
Described automobile navigation device user side also is provided with a voice operation demonstrator, and this voice operation demonstrator is connected with described Navigation Control Unit.
Described navigation center control end also comprises a urban traffic network topological structure module, and this module is used for setting up the road network topology structure according to each crossing of urban traffic network and annexation thereof, sets the formation between the interconnective crossing.
Described navigation center control end also comprises flow rate calculation module and graph inquiring module.
Compared with prior art, the intellectual urban traffic control system of the present invention has following characteristics:
1, all vehicle can both be understood the speed of a motor vehicle and the congestion of all roads in real time.
Whether 2, vehicle mounted GPS guidance system can be selected best path according to the congestion of road, rather than can only travel according to pre-determined route as present GPS navigation system, and no matter whether this route is unimpeded at present, repairing the roads or traffic jam.
