What is the purpose of the newly installed gantry on the highway?

It is part of the nationwide implementation of a segmented toll collection system using ETC gantries on highways. The ETC gantry is equipped with devices to identify vehicle information. Through two-way microwave communication between the electronic license plate installed on the vehicle's windshield and the microwave antenna on the ETC lane gantry at the toll station, big data processing is utilized. This allows vehicles to pay tolls without stopping when passing through highway toll stations, with payment deducted after passage. Below is the toll collection method via ETC gantries: 1. The biggest advantage of highway gantries is enabling non-stop toll collection. Vehicles are automatically charged when passing under the gantry, ensuring more accurate tolling. 2. Toll amounts are rounded to the nearest multiple of 5, currently using "rounding" to the nearest "yuan." For ETC card users enjoying a 5% discount, amounts are rounded to the nearest "fen."
Having driven on highways for many years, these newly installed gantries have left a deep impression on me. They are the core equipment of the ETC toll collection system. As vehicles pass under them, the overhead antennas automatically scan the onboard ETC tags, completing seamless fee deduction. In the past, toll stations often had long queues, but now direct passage is much faster, saving a lot of time. The gantries are also equipped with high-definition cameras to monitor vehicle speed—speeding will be captured and fined, so I remind everyone to always obey the speed limits and drive safely. They are installed at peak traffic points to help transportation departments analyze real-time flow and reduce congestion. Personally, I recommend checking in advance whether your ETC device is working properly to avoid billing errors. They make travel more efficient and safer, truly a significant improvement in driving life. I’ve passed through them countless times, and the experience has changed dramatically.
As an automotive technology enthusiast, I analyze the working mechanism of high-speed gantry systems. They integrate RFID readers and infrared sensors, specifically designed for automatic toll collection and monitoring. When a vehicle passes through, the system identifies the ETC device within milliseconds, and the backend accurately deducts the fee without manual intervention. Simultaneously, the camera module captures speed data, recording violations if the speed limit is exceeded. Post-installation, it reduces congestion at toll stations and enhances overall traffic efficiency. The data can also be shared via network connectivity, laying the foundation for smart road network construction. Drivers are advised to ensure their ETC tags have sufficient battery power for smooth passage. This technological innovation reflects the trend of intelligent management in modern transportation.
