According to concerning sectional statistic, our country road traffic is relatively prosperous, the length of the highway more than any other country, economy is developing rapidly.

according to concerning sectional statistic, our country road traffic is relatively prosperous, the highway 【 The highway belongs to high grade highway. 】 Length is more than any other country, the rapid economic development. Assume that you look closely, you will find that the freeway monitor is the five step of three steps two step, two step operation, can say that there is no dead Angle, especially the ETC ETC is no stop electronic toll collection system, the ETC lanes are for those with ETC vehicle-mounted device used in vehicles, using electronic toll collection. 】 Since the implementation of comprehensive road gantry has many. In the frame, usually many different types of camera equipment, then what is the function of these cameras and frame? The role of the high speed gantry to identify the vehicle information of equipment in the rack, ETC) by means of the electronic equipment in the vehicle windshield plates, and the ETC lanes gantry microwave antenna 【 Work on wave, centimetric wave and millimeter wave band transmitting or receiving antenna, collectively known as microwave antenna. 】 Two-way microwave communication' Microwave communication ( 微波通信) , is the use of wavelength between 1 mm to 1 m electromagnetic wave - — Microwave communication. 】 And big data processing. Vehicles through the bridge toll station, not parking fees, after the passage of deduction. In other words, the longmen equipment can intelligently identify vehicles travel way, for example, from A to B may have multiple high-speed way on the ground. According to both the shortest interval charging originally, according to longmen practice interval charge now. Rate varies between interval, gantry used for confessed travel distance of the vehicle, and road charging based on practice. In addition, the goal can also record and capture is not according to the travel lanes of vehicles, record the speed of vehicles, and which is good he can fine confessed a vehicle speed information, etc. Violations monitoring is not only the ETC of longmen sensor system, and surveillance camera car situation, such as speed, emergency lane monitoring, safety harness, ETC. Camera is equipped with hd equipment, not only can adopt illegal ACTS, will also be able to clearly flash cars, car number, and even drive member photos, convenient owner sweep illegal behavior. Especially in the big car with speed limit signs, overtaking careful when you drive, to control the speed of a top speed of the following, otherwise will be deducted may. Interval velocity measurement adjustment traffic now many places have electronic speed limit signs, you will find that the electronic speed limit signs of speed limit standard changes often, he was using traffic monitoring system. Gantry portion of camera is traffic flow monitoring system, he was able to accounting period must be here by the number of vehicles and speed, and combined with the traffic conditions before and after the adjustment the maximum speed of vehicles, and then adjust the maximum limit traffic flow of communication power, avoid congestion for a long time. In a certain period of time, through the calculation of the vehicle moving interval, can get the vehicle average speed per hour, and then identifying whether the vehicle suspected of speeding, called interval velocity measuring system.
