Crossroads traffic management control system

Abstract

Being connected to controller of signal lamp, U turn control signal lamp is installed above central line of road at rearward 50-200 m of major light of traffic signal. Stop line and parking area for vehicles of left turn and U turn are setup at corresponding position of down road of the U turn control signal lamp. Second stop line and parking area for straight going vehicles are setup at corresponding position of up road of the U turn control signal lamp. The stop line for left turn and second stop line for straight going vehicles are located at two sides of U turn control signal lamp respectively. For four lanes of narrow road with no isolated area in central area, stop line and parking area for left turn are setup at corresponding position of right side of down road adjacent to sideway. Advantages are: vehicles can make left turn as well as U turn; waiting time for traffic signal is reduced so as to release traffic jam at crossroad.

Description

1. Technical field: [0001] The invention relates to a traffic management control system, in particular to a novel crossroad traffic management control system. 2. Background technology: [0002] One of the symbols of the rapid development of the modern economy is the rapid development of urban transportation. With the process of reform and opening up in our country, people's living standards have been continuously improved, and social vehicles have increased sharply. Although road transportation facilities have been continuously improved and perfected, road improvements often Can't keep up with the development of motor vehicles, traffic congestion and congestion in major and medium-sized cities across the country are becoming more and more serious. Traffic congestion is a serious problem that affects urban development and urban image. It affects urban construction and citizens' emotions, and is related to material civilization and spirituality. The construction of civilizatio...

Problems solved by technology

[0003] The traditional intersection traffic control system is composed of red, green and yellow signal lights and a certain signal layout. , the vehicles driving on the road are faced with three travel directions of turning left, going straight, and turning right. When driving to the stop line at the crossing, if the vehicles of various traveling directions randomly enter the crossing randomly, the three directions interfere with each other. cause crossing blockage

In recent years, phase signal lights have been used to decompose the command signals at intersections into left-turn signals, straight-going signals, and right-turn signals. This command signal can greatly reduce conflict points, but because the left-turn signal takes a long time, it usually takes several traffic lights to pass. The traffic capacity of intersections has not been greatly improved. In order to prevent traffic jams, many intersections have set signs prohibiting left-turn vehicles, so that vehicles that need to turn left must detour for a long distance before passing, causing new traffic pressure.

[0004] In order to improve the quality of traffic management and alleviate the phenomenon of urban vehicle congestion, many patent applicants also take this as an entry point, such as Chinese patent CN 1255570A, application number is 98123264.7, and the name is called: "Urban Road Level Crossing Traffic Dispatching and Diverting Method and Its management device "is equipped with crossing stop lines, dispatching lanes, etc. at crossings, and all motor vehicles, bicycles and pedestrians are provided with corresponding command signals for all-round command. This method is expected to alleviate the existing Traffic crossings are blocked, but the dredging of such crossings has not really solved the problem of moving left-turning vehicles

Chinese patent CN 1560365A, the application number is 200410039490.2, the name is: "existing crossroads change the setting and use method of traffic management mode", it adopts the transformation of signal lights, the design of road surface and new crossroad traffic method to adjust motor vehicle flow, Make a left-turn vehicle on the upper lane when the signal in front is red, turn left and enter the down lane and wait at the stop line. When the signal light on the main road at the intersection is red, turn left quickly and drive out of the intersection. Vehicles turning left cannot make a right-angle turn , can not cross the marked slash, otherwise it will cause traffic chaos. Although this method has greatly solved the problem of crossing congestion in existing traffic, it is not satisfactory, especially the left turn of left-turning vehicles. Randomness, it is impossible to drive strictly according to the regulations, this method needs to be further improved and perfected
