Can ETC locate a vehicle?

ETC cannot locate a vehicle. ETC is an electronic toll collection system that allows vehicles to pass through without stopping. ETC dedicated lanes are designed for vehicles equipped with ETC onboard units, utilizing electronic toll collection methods. It is a radio frequency system without any positioning capabilities. More details are as follows: 1. The ETC system is currently the most advanced toll collection method for roads and bridges worldwide. It uses dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station. This system integrates with computer networking technology to process backend settlements with banks, enabling vehicles to pass through toll stations without stopping while paying the toll. 2. Implementing non-stop toll collection allows vehicles to pass through at high speeds (tens to over a hundred kilometers per hour), significantly improving road traffic capacity. The shift to electronic tolling reduces the cost of toll management and enhances vehicle operational efficiency. It also greatly reduces noise and exhaust emissions at toll booths. With the substantial increase in traffic capacity, the scale of toll stations can be reduced, saving on infrastructure and management costs. 3. Additionally, for cities, the ETC system is not just an advanced tolling technology but also an effective traffic management tool that uses economic leverage to regulate traffic flow. For busy bridges and tunnels, the ETC system overcomes the limitations of monthly passes and manual toll collection, effectively improving the financial recovery capability of these municipal facilities.
I used to drive a truck and often used ETC. It can indeed locate the vehicle, but only works near toll stations. ETC relies on communication between the onboard device and the toll station reader, similar to scanning a barcode at a supermarket, with a range of just a dozen meters. When passing through a toll station, it can record the location and time for charging, but it doesn’t have a GPS antenna, so it can’t continuously track my movements on the road. If someone is concerned about privacy, ETC data is just a record of toll charges and won’t reveal the entire journey. However, if the vehicle is equipped with a car navigation system or a mobile app, that’s what can truly track your location. In short, ETC makes toll collection more convenient, but its positioning function is very limited.
