Gantry realizes segmented charging through ETC. Equipment for identifying vehicle information is installed on ETC gantry. Through the electronic license plate installed on the windshield of the vehicle, it carries out two-way microwave communication with the microwave antenna on the ETC gantry of the toll station, and then uses big data processing. Vehicles can pay tolls without stopping when passing through Luqiao toll station, and then deduct them.

In other words, the gantry device can intelligently identify the driving trajectory of the vehicle. For example, there may be multiple high-speed routes from the same location A to the same location B. In the past, it was charged according to the shortest route between the two places, and now Longmen is charged according to the actual route. Different distances, different charges. The role of the gantry is to identify the path of the vehicle and then charge according to the actual route.

The biggest advantage of high-speed gantry is that it can realize non-stop charging, and the vehicle will automatically deduct the high-speed fee through the gantry, which makes the charging more accurate. In the past, according to the rounding rule of "37 is 5 and 28 is 0", the charge amount was a multiple of 5. Now round to the nearest yuan, and round to the nearest minute if the ETC card is 15% off.

For example, in the previous charging standards, car expressways were generally charged at 0.4 yuan/km, and the minimum charging amount started in 5 yuan, and was calculated at within 12 yuan 10 yuan, 13 yuan to 17 yuan 15 yuan, which exceeded 18 yuan by 20 yuan.

Generally speaking, the gantry mounted on high-speed is beneficial to car owners, which can realize non-stop charging and alleviate traffic congestion. The way of "walking more and charging more" is more reasonable.
