Traffic guidance system for improving traffic efficiency of traffic light intersection

Abstract

The invention discloses a traffic guidance system for improving the traffic efficiency of a traffic light intersection, and the system comprises a first module and a second module. The first module isused for performing calculation when the red light of the traffic light is finished or a green light is coming; the second module is used for comprehensively utilizing LED display screen resources; the first module is electrically connected with the second module; the first module is electrically connected with the second module; and the second module is connected with an LED display screen usedfor displaying the corresponding content of the output signal of the first module. The beneficial effects of the invention are that: the problem is solved that at the traffic light intersection with astraight driving waiting area and a left-turn vehicle waiting area, when the vehicle enters the waiting area for waiting for, so that the traffic efficiency is improved, the problem of interference to vehicles in other directions is reduced as much as possible, the influence on pedestrians and vehicles after the traffic signal controller changes the traffic light timing is reduced when the medium-sized intelligent rail tramcar passes through the signal light intersection preferentially, accidents are reduced, and the satisfaction of citizens is improved.

Description

technical field [0001] The invention relates to the field of traffic guidance systems, in particular to a traffic guidance system for improving traffic efficiency at traffic light intersections. Background technique [0002] Traffic guidance system, or traffic flow guidance system, also known as traffic route guidance system or vehicle navigation system, is based on modern technologies such as electronics, computers, networks and communications, and provides road users with the optimal route according to the origin and destination of travelers Guide instructions or help road users find an optimal route from the starting point to the destination by obtaining real-time traffic information. The characteristic of this system is that it takes people, vehicles and roads into consideration, improves the road traffic system by inducing the travel behavior of road users, prevents traffic jams, reduces the time vehicles stay on the road, and finally realizes traffic flow. Reasonable ...

Problems solved by technology

[0003] At the existing intersections with LED board prompts, the LED board will light up synchronously according to the lateral left turn signal light to remind the vehicle to enter the waiting area for straight traffic. Vehicles turning left sideways cause interference and affect traffic efficiency; according to the intersection prompted by the LED board, when the straight signal lights in the same direction turn green, the vehicle enters the waiting area for turning left and waits for passage. At this time, the time to enter the waiting area is too late Early, after the vehicle enters, it will cause interference to the oncoming straight vehicles and affect the traffic efficiency; there is no reminder when the intersection enters the waiting area, and only the driver of the motor vehicle can judge the time to enter the straight waiting area and the left turn waiting area , most motor vehicle drivers dare not enter or enter at will, which does not achieve the traffic effect that the waiting area should have; for the convoy waiting for the signal light at the intersection of signal lights, it will take 5-10 seconds for the convoy to move from completely static to fully moving. The time when the vehicle enters the through-travel waiting zone and the left-turn vehicle waiting zone is too early. The whole convoy just takes 5-10 seconds to move, but because the passing time ahead has not yet arrived, the vehicle will stop at the waiting zone. If the area continues to wait, the entire convoy will stop again. When the green light is on, the convoy will spend another 5-10 seconds to start the convoy. If the plan is changed, vehicles traveling in other directions will turn to red lights directly after a three-second yellow light transition. At this time, the countdown timer will also stop working, vehicles in the same direction will continue to pass, and vehicles in other directions will wait; this will result in the following Two foreign problems: A. The signal lights suddenly terminate the passage of normal vehicles and pedestrians, causing vehicles and pedestrians to run the red light by mistake, which has potential safety hazards; B. Vehicles and pedestrians in other directions do not know the reason for the sudden long-term red light. Complaints remain high; the outdoor LED traffic guidance display screen is installed on the intersection signal light pole, which is only used to display traffic safety and other promotional content, and cannot be used to prompt vehicle guidance information or real-time road conditions ahead, etc. The traffic guidance display screen is not well utilized. achieve expected effect
