Problems solved by technology
The increase of private vehicles is undoubtedly a root cause of traffic congestion, but the unreasonable setting of traffic lights is also another factor that artificially leads to traffic congestion
There are not many vehicles in one direction at many intersections, but relatively long signal lights are also set up, resulting in a long queue of vehicles in the other direction, which greatly wastes intersection resources

The invention discloses a traffic light vehicle flow control system, which comprises a central processor, a counting system and a display system, wherein the counting system comprises a pressure sensor pre-buried in the center of a road, a unit controller, a video acquisition terminal and an A / D converter, the display system comprises a traffic signal lamp and a digital display, the pressure sensor transmits a signal to the unit controller, the unit controller is connected with the video acquisition terminal, the video acquisition terminal is connected with the central processor by means of the A / D converter, and the central processor is in control connection with the traffic signal lamp and the digital display. The traffic light vehicle flow control system can effectively adjust the length of the signal lamp according to the road condition, and improves the humanized passing performance of the road.
Description
technical field [0001] The invention relates to the technical field of traffic control, in particular to a traffic light vehicle flow control system. Background technique [0002] At present, many large and medium-sized cities in China are facing a chronic urban disease that needs to be solved urgently - traffic congestion. With the development of our country's economy, the average annual household income continues to increase, and the number of private cars soars, causing many cities to be overwhelmed by traffic. The increase of private vehicles is undoubtedly a root cause of traffic congestion, but the irrational setting of traffic lights is also another factor that causes traffic congestion artificially. There are not many vehicles in a certain direction at many intersections, but relatively long signal lights are also set up, resulting in a long queue of vehicles in the other direction, which greatly wastes intersection resources. This intelligent command system judges...
