Abstract
The invention belongs to the traffic light field, in particular a traffic light time automatic switching method. The method is characterized in that the switching method at least contains traffic lights, and a vehicle speed detection device and a processing unit which are arranged on a traffic light control channel, wherein the processing unit continuously detects the vehicle flow and vehicle speed information of the vehicle speed detection device arranged on crossroads, when the number of vehicles in one direction within a certain journey is more than twice of the number of vehicles in the other direction within a certain journey, and the processing unit controls the traffic lights to ensure that the time of the green light in the channel with slower flow exceeds that in the other channel. When traffic jam happens in one direction while the vehicle flow in the other direction is low, the switching method of the invention can be used to automatically adjust the traffic light time.
Description
Technical field
The invention belongs to traffic lights field, particularly traffic light time automatic switching method.
Background technology
All be changeless traffic lights switching time of crossroad, city mostly, traffic hazard appears in the vehicle in the time of many on direction, cause this direction vehicle to stop up, vertical direction then traffic is normal, but the traffic lights of two vertical direction are still identical switching time, the vehicle that is easy to form a direction is quite a lot of, can't move ahead, and a direction is then gone everywhere without any hindrance here.Adopting image recognition to carry out transport information identification, be the feasible scheme of a kind of theory, but the problem that implements is many, because uncertain factor is too many.
Summary of the invention
The purpose of this invention is to provide a kind of traffic light time automatic switching method, so that can stop up at a certain direction vehicle, and the other direction vehicle flowrate realizes adjusting automatically the traffic lights time seldom the time.
The object of the present invention is achieved like this, design a kind of traffic light time automatic switching method, it is characterized in that: which comprises at least traffic lights, vehicle speed pick-up unit and the processing unit arranged on the traffic lights control channel, processing unit constantly detects vehicle flow and the speed information that the vehicle speed pick-up unit arranged on the cross passage provides, vehicle in the vehicle of a direction in the stretch journey surpasses other direction stretch journey is more than 2 times the time, and processing unit control traffic lights make the time of the slow passage green time of flow velocity greater than another passage green light.
Described vehicle speed pick-up unit is to constitute by underground inductive coil and testing circuit that stretch journey before and after passage is provided with, and testing circuit offers processing unit by the vehicles passing in and out number that coil before and after detecting detects.
Described vehicle speed pick-up unit is that stretch journey vehicles passing in and out number offers processing unit before and after detecting by Flame Image Process by the video camera in the stretch journey setting of passage front and back.
Advantage of the present invention is: the present invention is owing to the stretch journey at different directions is provided with the vehicle speed pick-up unit, by the vehicle number in the stretch journey that detects different directions, by the vehicle fleet size in the stretch journey of different directions is compared, vehicle in the vehicle of a direction in the stretch journey surpasses other direction stretch journey is more than 2 times the time, processing unit control traffic lights make the time of the slow passage green time of flow velocity greater than another passage green light, realize adjusting automatically the traffic lights time, alleviate because the traffic jam that miscarriage causes.
Description of drawings
The invention will be further described below in conjunction with embodiment:
Fig. 1 is the embodiment of the invention 1 structural representation.
Among the figure: 1, north and south traffic lights; 2, north and south second inductive coil; 3, thing highway section; 4, thing first inductive coil; 5, north and south first inductive coil; 6, highway section, north and south; 7, thing second inductive coil; 8, thing traffic lights.
Embodiment
As shown in Figure 1, as on the highway section, north and south 6 north and south first inductive coil 5 and north and south second inductive coil 2 being set at the parting of the ways, thing first inductive coil 4 and thing second inductive coil 7 are set on the thing highway section 3 at the parting of the ways.North and south first inductive coil 5 and north and south second inductive coil 2 detect the vehicle fleet size in highway section, north and south 6, thing first inductive coil 4 and thing second inductive coil 7 detect the vehicle fleet size in thing highway section 3, when highway section, north and south 6 when the vehicle fleet size in thing highway section 3 is more than 2 times, processing unit control north and south traffic lights 1 green time is greater than thing traffic lights 8.On the contrary, when highway section, north and south 6 when the vehicle fleet size in thing highway section 3 is more than 2 times, processing unit control north and south traffic lights 1 green time is less than thing traffic lights 8.
As different from Example 1, highway section, north and south 6 and thing highway section 3 respectively are equipped with video camera at the parting of the ways, by camera review processing detection highway section, north and south 6 and thing highway section 3 vehicle numbers are offered processing unit.Same when highway section, north and south 6 when the vehicle fleet size in thing highway section 3 is more than 2 times, processing unit is controlled north and south traffic lights 1 green time greater than thing traffic lights 8.On the contrary, when highway section, north and south 6 when the vehicle fleet size in thing highway section 3 is more than 2 times, processing unit control north and south traffic lights 1 green time is less than thing traffic lights 8.
