Can ETC locate a vehicle?
1 Answers
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.
