Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] The realization principle of pre-formation without waiting traffic flow is to perform pre-formation on a section of road 200-500 meters before the intersection to be passed (determine the distance of pre-formation according to the situation of the intersection and traffic flow), and finally make the queue pass the intersection in an orderly manner. The specific implementation method is to install front-end vehicle position, speed, quantity speedometer 2 and video camera 1 (specifically, radar speedometer can be used, from the intersection to the radar speedometer at the front end) The distance is the pre-formation area). Install another set of speedometer 2 and camera 1 200 meters behind the first group of speedometer 2 and camera 1 set in front of the intersection, so that the two radar speedometers can transmit the vehicle's position, number of vehicles and spe...

Abstract

A pre-formation no-wait traffic flow control method. The invention relates to a traffic control device, which belongs to the technical field of traffic control. The method comprises the following steps that: a video camera and a velocimeter are arranged at a crossing, and the acquired data is processed by a computer respectively; signals of number, speed and position of vehicles of the velocimeter are processed to generate ideal pre-formation data, wherein one set of signals are transmitted to a street lamp signal control cabinet and a lamp signal display, and the other set of signals and the data came from the video camera are recombined and processed; real-time picture signals of the video camera and the signals of the velocimeter are processed into simplified pictures, analyzed and compared with the pre-formation data together and are processed and overlapped with actual road condition pictures of the video camera to synthesize control pictures, wherein the one set of signals are transmitted to an crossing display screen, and the other set of signals are transmitted to a signal transmitter arranged at the crossing and are received by a vehicle carrier and a display. A driver adjusts in time to enter a correct formation position to realize the formation, finally a team sequentially passes through the crossing, and thus cars pass through the crossing without stopping.

Description

Technical field [0001] The invention relates to a preformation non-waiting traffic flow control image generation circuit system, which belongs to the technical field of traffic control. Background technique [0002] Current traffic control is realized by the traffic lights at intersections. Stop at a red light and go at a green light. This is the most basic traffic law we follow. With the continuous increase of vehicles, the waiting time at crossings is getting longer and longer, and almost all crossings will wait, wasting time, and the engine will discharge a large amount of exhaust gas at idle speed. Traffic congestion has become one of the most troublesome things in modern society. In order to solve this problem, we are forced to consider dynamic traffic management methods, so that cars can pass through intersections without stopping. Contents of the invention [0003] In order to overcome the problem of existing traffic congestion, the present invention provides a d...
