Embodiment 1

[0026] A traffic control method at a road intersection based on geomagnetic detection in this embodiment mainly includes the following steps:

[0027] Step S101: If it is detected that there is a vehicle in the forward direction of the road and there is no vehicle in the opposite direction of the road, a green light is displayed in the forward direction of the road to allow the vehicle in the forward direction to pass;

[0028] Step S102: If it is detected that there is a car on the opposite side of the road and there is no car on the forward side of the road, a green light will be displayed on the opposite side of the road to allow the vehicle on the opposite side of the road to pass;

[0029] Step S103: If in step S101 the time for which the green light continues to be displayed is greater than the set threshold T, the road is reversed and converted to display a green light to allow the vehicle in the reverse direction to pass; if the time for which the green light is continu...

Embodiment 2

[0033] This embodiment is further optimized on the basis of embodiment 1, such as figure 2 As shown, in the step S101, when it is first detected that there is a vehicle in the forward direction of the road and there is no vehicle in the reverse direction of the road, the green light is displayed for N seconds in the forward direction of the road, and the vehicle in the forward direction and reverse direction of the road is detected again after the green light is on for N seconds. Numerical value; If it is detected again that there is a car in the forward direction of the road and there is no car in the reverse direction of the road, the green light is displayed in the forward direction of the road for N seconds; if it is detected in the step S102 for the first time that there is a car in the reverse direction of the road and there is no car in the forward direction of the road, then the reverse direction of the road is detected. The green light is displayed for N seconds. Afte...

Embodiment 3

[0038] This embodiment is further optimized on the basis of embodiment 1 or 2, T=2 (T 1 +T 2 ), where T 1 is the green light time for the forward traffic of the road when the road is normal traffic, the T 2 The green light time for reverse traffic when the road is normal traffic.

[0039] T 1 , T 2 It is the green light time of the forward direction and the reverse direction of the road set in the original program. When the conditions of vehicles in the forward direction and vehicles in the reverse direction are met, the traffic lights will be executed according to the original program, that is, the traffic lights will follow the set forward direction. Fixed travel time T 1 , Reverse constant travel time T 2 Running; when the conditions of no cars in the forward direction and no cars in the reverse direction are satisfied, the traffic lights will also be executed according to the original procedure, that is, the traffic lights will be executed according to the set forwar...

Abstract

The invention discloses a traffic control method for a road intersection, based on geomagnetic detection. The traffic control method for a road intersection, based on geomagnetic detection includes the steps: judging whether a road is idle in real time by judging the vehicle situation of the forward and the reverse direction of the road, and if the road is idle in the forward direction, guaranteeing the reverse vehicles on the road can quickly pass, and if the road is idle in the reverse direction, guaranteeing that the forward vehicles on the road can quickly pass; and at the same time, setting a threshold T to effectively avoid the error for vehicle detection or the situation that the road is configured to be no passing continuously because of a detection error, so that the traffic control method for a road intersection, based on geomagnetic detection has higher practicality. The traffic control method for a road intersection, based on geomagnetic detection can adjust the transit time in all directions by means of the real-time traffic flow so as to maximally reduce the waiting time of the vehicles. The traffic control method for a road intersection, based on geomagnetic detection is flexible to control, is low in cost and is convenient for maintenance. Besides, the adaptive control method of the traffic control method for a road intersection, based on geomagnetic detection is suitable for all the intersections, especially road intersections with a higher vacancy rate in the suburbs or an open country.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic control, in particular, it is a traffic control method at road intersections based on geomagnetic detection. Background technique [0002] At present, there are still some problems in the field of intelligent traffic control in China: (1) Due to my country's unique ternary mixed traffic environment, foreign traffic control systems cannot well adapt to my country's traffic flow changes, such as the British SCOOT and Australian SCATS systems , the SCOOT system has high requirements for the accuracy of the mathematical model, so the simulation time will be longer, which will cause a contradiction between real-time and reliability. The SCATS system is a real-time scheme selection control system, but because it does not use traffic models, The optimization process of the timing scheme is limited, and the flexibility is not enough, so the control effect will inevitably be unsatisfactory; (2) A...
