Abstract

A linearly distributed dynamic traffic signal system. A series of linearly distributed dynamic signal points are arranged along roads. When the signal at each point is coordinated with a traffic light signal at the intersection, a dynamic signal is provided for drivers between intersections, so that vehicle streams and streams of people, as the participants in traffic, are guided in real time to choose to drive with an appropriate speed and on a road dynamic position and rapidly pass the intersection at a green light signal.

Description

Linear distributed dynamic traffic signal system

Technical field

The invention relates to a linear distributed dynamic traffic signal system

Background technique

At present, in order to solve the problem of urban traffic congestion, some cities use the "green wave band" technology to coordinate the traffic lights at the intersections, so that the cars encounter green light signals when passing through the intersections to increase the speed. The "Green Wave Belt" technology requires the car to travel at a preset speed, but as the traffic increases, each person participates in the traffic, the location, the driving habits and the skills. When various accidental factors increase, part of the traffic flow It does not pass through the intersection as quickly as expected.

The "Green Wave Belt" technology requires a certain speed to pass, so that it can just meet the green light signal. If it is too fast and too slow, it will stop at the next signal cycle such as the intersection, and it will also affect the car driving fast behind. When more cars are parked at the intersection, the advantage of the "green wave belt" technology to increase the speed of the car will not work. When a plurality of "green wave bands" are intertwined with each other, since the distances of the respective sections are different, it is impossible to accurately match the same speed.

The speed of the intersection traffic determines whether the city is unblocked or not. But nowadays, when passing through the intersection, many cars have to stop and wait for it to go. It has become a normal state, so how to make the traffic flow just meet the green light signal when passing through the intersection. It is the focus of the present invention to pass through the intersection without being fast or slow.

Summary of the invention

The system is to set up a series of linear dynamic signal points along the road. By coordinating the signal of each point with the intersection traffic light signal, the driver is provided with a dynamic signal between the intersections to guide the participating traffic in real time. The traffic flow and the flow of people select the appropriate speed and dynamic position of the road to drive and quickly pass the green light signal at the intersection.

In this system, after each signal point starts to run, a moving ribbon (similar to neon) composed of different colors will be formed. In the ribbon: (color 1) The position of the region can be set to go straight through the green light signal at the intersection. The dynamic position, (color 2) The position of the area movement can be set to the left and right turn of the traffic flow through the dynamic position of the green light signal at the intersection, and the dynamic position of the red light signal at the intersection of the (color 3) area is moved. During the driving process, the driver can adjust the speed and dynamic position of the different color dynamic signals to keep up with the (color 1 and color 2) areas, and smoothly pass the green light signal at the intersection to improve the green letter ratio.

The system creates moving traffic signals along each road. It guides the traffic flow in all directions and travels smoothly through the green light signal at the intersection. The characteristic is that even if some accidental factors affect the speed during driving, the driver can refer to the setting at any time. Dynamic signals along the line adjust their speed and dynamic position to smoothly pass the green light signal.

The existing traffic light signal only guides and controls the traffic flow near the intersection. Most of the cars stop and start again to pass through the intersection. This is orderly, but the speed is very slow, and the intersection has a slow speed. Order state. The system is real-time dynamic guidance and control when the traffic has not reached the intersection, creating conditions for more vehicles to quickly pass through the intersection, so that the intersection presents a fast and orderly state of passage, thereby improving the city. Overall speed.

The system can also set different vehicle flow guiding speeds for various road sections, providing the possibility for multiple "green wave bands" to interweave and coordinate. DRAWINGS
