Abstract
The present invention discloses a crossroad traffic light intelligent control method and system on the basis of vehicle positioning. The method comprises: obtaining vehicle positioning information on two roads which form a crossroad in real time; analyzing the crowded grade of each road in the two roads in real time through the vehicle positioning information; and when the crowded grade of only one road in the two roads is larger than a preset degree, setting the traffic light corresponding to the road to be a red light, and setting the traffic light of the other road to be a green light. According to the invention, firstly, on the basis of the vehicle positioning information, the crowded grade of two roads at the crossroad are analyzed, and when the crowded grade of only one road in the two roads is larger than a preset degree, the traffic light corresponding to the road is set to be a red light, and the traffic light of the other road is set to be a green light, therefore the condition that vehicles on the two roads cannot be dispersed is avoided, the vehicle dispersion effect of roads on the crossroad is improved, and the traffic jam phenomenon is reduced.
Description
Technical field
The present invention relates to traffic control technical field, particularly to a kind of crossroad intelligent traffic light control method based on vehicle location and system。
Background technology
It is known that in order to ensure as far as possible that traffic safety, now a lot of crossroads are equipped with traffic lights, by switching the traffic lights on crossroad, it may be achieved forbid or allow certain road vehicle to move。
It is currently mostly, by exchange-column shift mode, the traffic lights on crossroad is switched over control, when the two road (being set to road A and road B) that this mode goes up at the parting of the ways are unimpeded, effectively vehicle can be dredged, but, once a certain road (if being road A) on crossroad occurs in that traffic congestion phenomenon, so when according to exchange-column shift mode, the traffic lights of road A being switched to green light, when the traffic lights of road B is switched to red light, road A will be caused because being originally at congestion status and vehicle cannot be dredged, road B is then because corresponding traffic lights is red light, also cannot be carried out dredging of vehicle。And, it is also possible to following situation occurs, owing to the vehicle fleet size on direction, road A place is too much, vehicle on road A place at the parting of the ways is occurred in that block up, even if now the traffic lights of road B switches for green light, due to the vehicle on road A now already at crossroad place, thus hindering the normal pass of vehicle on road B。Visible, when a certain road on crossroad occurs in that traffic congestion phenomenon, the mode of exchange-column shift traffic lights cannot be effectively improved vehicle and dredge effect, it could even be possible to aggravation traffic jam。
