Is Full-Range Speed Detection Really Full-Range?
1 Answers
The so-called "full-range" means that on a relatively long road section, there are speed monitoring devices at every location without any omissions. Here is some relevant information about vehicle speed detection: 1. Speed detection methods: (1) Loop detection: This is a classic method with good detection results. It is commonly used in southern regions such as Shanghai and Guangdong. The system determines whether a vehicle is speeding based on its speed when passing parallel loops and captures photographic evidence. (2) Video detection: This method analyzes continuous video images to track the behavior of violating vehicles and controls the camera to capture violations. The advantage of this system is that it is not limited by road conditions, does not require road destruction for installation, or the embedding of induction loops underground. Instead, it detects traffic data by setting up cameras above the road, making it a new-generation road vehicle detection method. 2. Precautions: Cameras at intersections can also capture violations, including not only running red lights and speeding but also illegal lane changes on solid lines and crossing lines. The capture efficiency during the day can reach over 95%, and at night, it is still around 90% due to night vision capabilities.
