What is Section Speed Control?
2 Answers
Section speed control is a monitoring and capture system established by setting up two cameras at two adjacent monitoring points on the same road section. Its principle is based on calculating the average speed of a vehicle on that road section by measuring the time it takes for the vehicle to pass between the two monitoring points. It then determines whether the vehicle has violated the speed limit based on the speed standard set for that section. Section speed control provides effective technical support for public security departments to combat various illegal activities such as speeding violations, hit-and-run incidents, and suspicious vehicles, enabling centralized and efficient management. This information can also be used for automatic analysis and statistics of traffic flow, as well as serving as legal evidence for handling vehicles involved in illegal or non-compliant activities.
I remember encountering average speed check zones several times while driving. These are sections of the highway equipped with two or more pairs of cameras at the start and end points, which record your license plate and passing time to calculate whether your average speed over the entire segment exceeds the limit. This speed monitoring method primarily targets drivers who slam on their brakes just before and after spot speed checks, encouraging everyone to maintain the speed limit throughout the entire journey rather than just braking momentarily to pass inspection. The advantage is that it more fairly controls traffic speed and reduces accidents, but if you stop or change lanes midway, the data might be inaccurate, leading to wrongful penalties. Personally, I think it helps cultivate good driving habits by not just focusing on momentary speeds but emphasizing smooth driving.
