Problems solved by technology

This method does not capture the difference
[0009] To sum up, the existing expressway vehicle speed monitoring and management system is either complex in structure, high in cost, high in operating cost, troublesome in installation, use and maintenance; or too simple to play a real monitoring role
None of them can realize the real and effective whole-process monitoring of the vehicles running on the expressway, so they cannot meet the general needs of expressway management.

Embodiment

[0089] Implementation example analysis:

[0090] Assume that a certain expressway is 200 kilometers long, has 20 entrances and exits, and each exit has an average of 4 passages. The traffic management authority plans to monitor the speed of vehicles throughout the expressway, so a signal needs to be set up at an average distance of 2 kilometers. At the same time, assuming that the entire expressway has a 160-kilometer road section, the uplink and downlink lanes are not far apart, and the same signal machine can be used. Therefore, about 120 need to be placed on the entire expressway, and the price of each signal is about 200 yuan, including other auxiliary equipment and installation costs in the range of 1,000-1,500 yuan, and a total investment of about 150,000 yuan is required; There are 100 readers, and the cost of each reader is about 300 yuan, which requires an investment of about 30,000 yuan, and the computer only needs to use the existing equipment; the sales price of e...

Abstract

This invention relates to one high speed road traffic speed monitor management, which solves the problem of current high speed road monitor and management system of complex structure and high price and troublesome use and maintaining and discloses one full day high speed road automatic radio frequency car speed monitor system. This invention combines the speed test and car identification to use current high speed road charge system for work.

Description

technical field [0001] The invention relates to vehicle speed measurement, identification and monitoring management. Background technique [0002] The main methods of speed measurement of existing vehicles are: radar speed measurement, laser speed measurement, and ground sense coil speed measurement; identity recognition generally adopts the method of naked eye recognition and video camera combined with image processing; for the management of speeding vehicles, on-site interception punishment and The management method of record keeping. In addition, there are also places at expressway exits, where the time difference between vehicles entering and exiting the expressway is used to calculate the average speed of vehicles to determine whether to speed. [0003] Radar and laser speed measurement methods [0004] Through the radar system installed at a fixed position or on the vehicle, the Doppler effect is directly used to measure the speed of the vehicle. After the speeding i...
