Description
Technical field
The utility model relates to the comprehensive managing and control system of traffic control and early warning, particularly a kind of intelligent transportation.
Background technology
Though can realize owing to reasons such as cost, technical maintenances, not being widely used to the control of traffic lights according to the actual make-and-break time of actual vehicle flowrate control traffic lights in some metropolitan main crossroads or zone, highway section.To the control of traffic lights, realize that more is sequential control, centralized control or the centralized management of carrying out according to the difference of time period.
The motor vehicle catastrophic failure is the main cause that causes China's urban traffic blocking at present, in time, handling failure will alleviate the generation of traffic jam significantly effectively.In traditional traffic control system, when traffic hazard or even little accident occurring, often because follow-up vehicle does not obtain reminding, early warning, traffic neither one right judgement to the place ahead, and vehicle is stifled more many more, accident is increasing, the phenomenon that minor accident causes big traffic jam or even traffic paralysis state can occur.At the highway that travels, in the rainy day, in night of dark, vehicle on various highways travels, if can clearly see some prompting and early warning information in suitable location, many accident potential can be destroyed surely about the traffic behavior in zone, highway section, the place ahead.
In addition, in relevant road traffic control and management, also seldom consider the relation of vehicle flowrate and road lighting.
Monitoring to the traffic intersection vehicle flowrate, the method of using both at home and abroad is a lot of at present, ground induction coil, infrared technique, video monitor etc. all are the methods of using always, to the control of the traffic lights of important traffic intersection and hinge, also can realize controlling the actual make-and-break time of this crossing traffic lamp according to actual vehicle flowrate.
To the video monitoring in important traffic intersection and zone, highway section realize also more general, especially, realized concentrated video monitor, for traffic administration provides reference and foundation in places such as traffic control centers in some big cities.
Present traffic information management has by wireless or electrophone, also has by intercom system, can give the driver who is administered with some communications of relevant traffic as taxi company, or the like.
The present prior art of China, there are the following problems:
1) though can provide reference mutually to control, video monitor, the Traffic Announcement three of traffic lights, direct relation not is to have a style of one's own three on the technical measures on it especially, and adheres to different administrative authoritys separately.
2) often because traffic information acquisition system is unsound, and the real-time information that obtains is less, Traffic Announcement often exists that area coverage is excessive, broadcasted content often is not highway section, the place ahead area contents that driving person is concerned about most, and the phenomenon that lags behind of life period; Intercom system is the phenomenon of life period hysteresis also.
3) because the real-time information that traffic information acquisition system obtains is less, the intelligent transportation in city has at present just realized function for monitoring mostly, and is far from bringing into play the effect of control function.
4) seldom have facility real-time, that give warning in advance is set on adjacent intersection or zone, highway section.
5) control separates with management function.
6) in the process that realizes the transport information construction, pay attention to technical research, and lack construction and technological development traffic information acquisition system hardware to the supple-settlement of the information that collects.
