4.29 (ETC) Automatic Toll Collection System
Leiditech recommends protection devices and solutions for the automatic toll collection system
The automatic toll collection system utilizes digital payment services in restricted areas, parking lots, toll bridges, and other controlled areas (including areas subject to congestion or urban toll restrictions). GNSS enables vehicle positioning, while electronic toll collection and open road toll collection rely on dedicated short range communication 3G/4G modules, WIFI modules, etc. between the vehicles and toll stations, enabling secure identification and payment processes.
At present, the ETC equipment OBU and RSU are based on DSRC communication technology and are only used for information connection and charging. Some areas can realize the path recognition function. With the rapid penetration of OBU equipment and the construction of RSU units, ETC is expected to become an important starting point for building the Vehicle-to-everything and moving towards intelligent transportation. In addition to vehicle to road, it can achieve vehicle to vehicle, vehicle to pedestrian and other communications. At the same time, in terms of function, it is not only charging, but also expanding to safety applications, It is expected that by 2023, the penetration rate of new cars will reach 67%, with a shipment of 75 million. Calculated at a unit price of 200 US dollars, the market size will reach 15 billion US dollars, and it has a deep technological accumulation in the wireless radio frequency communication industry. By entering the smart transportation field through ETC chips, it is expected to benefit from the explosion of the industry in the future.
