What does ETC toll photography mean?

[AniyahLynn]

ETC toll photography refers to the segmented toll collection system on highways. After the removal of provincial boundary toll stations on highways, a new 'gantry-based segmented toll collection' model has been adopted. This means both ETC vehicles and manually paid vehicles are charged uniformly based on their vehicle type and actual travel route. Gantries are devices installed at regular intervals along highways to calculate toll amounts. Each time a vehicle passes under a gantry, the cameras mounted on it photograph the vehicle to determine the toll based on the vehicle type, and the corresponding toll fee is deducted from the vehicle's ETC account. Upon exiting the highway, the total toll fee for that highway section is calculated by adding the fee for entering/exiting the ramp and the fees deducted at each gantry passed along the way.

Last time I was on the highway, I specifically observed the ETC cameras—those small devices mounted above the toll booths. When your car passes through the ETC lane, it snaps a photo of your license plate, mainly to verify vehicle information. Think about it—if the ETC card isn’t scanned properly or the OBU device malfunctions, the captured license plate photo can be matched with system records to avoid incorrect charges. Plus, now that highways use segment-based tolling, similar cameras are installed on gantries at different sections. Each snapshot records your passing location, and the total distance is calculated for the final fee. I also noticed these photos are stored for a while, so if there’s any doubt about the bill, you can request the photos for verification. Pretty user-friendly.

As someone who frequently drives long distances, I find the ETC camera function quite practical. Those inconspicuous-looking cameras mounted on toll gantries play a significant role. They instantly capture license plates as vehicles pass by, primarily serving dual verification: first deducting fees via ETC device detection, then cross-checking license plate photos to prevent fraudulent use. Nowadays, highway toll calculations are precise to every kilometer, and these cameras along the route act like checkpoints – each photo documents which road section you've traveled. Once when my ETC device ran out of power, the toll station relied on these photos to match my license plate information before granting passage. So don't underestimate that brief flash – it ensures both billing accuracy and traffic efficiency.

ETC cameras are those small cameras installed at highway toll stations. They automatically take photos of license plates as vehicles pass by, cross-verifying the information with ETC card swipes. This design is quite smart—if the device signal is weak, the photos serve as backup proof. Nowadays, every few dozen kilometers on the highway, there's a gantry structure equipped with these cameras. Each snapshot records the vehicle's location, and combined with time intervals, it calculates mileage fees. I've noticed the photos are very clear, but they're only used for billing verification and don't compromise privacy.

I remember being startled by the flash when first using the ETC lane, only to learn later it was for toll photo capture. The cameras mounted above toll booths specifically capture license plates, serving two main purposes: first, to match with ETC device information and prevent unauthorized use, and second, to act as trajectory recording points for segmented toll calculation. For instance, during long-distance travel, every gantry is equipped with such devices—each photo marks the vehicle's location, allowing the system to calculate the total fee based on these records. A friend of mine once got overcharged and had to retrieve these photos to prove the vehicle hadn't passed certain sections before getting a refund. While we usually overlook these details, they quietly ensure fair tolling.
