What does interval speed measurement mean?

[HenryRose]

Interval speed measurement involves setting up two adjacent monitoring points on the same road section. The average speed of a vehicle on that road section is calculated based on the time it takes for the vehicle to pass between these two monitoring points. The system then determines whether the vehicle has exceeded the speed limit according to the road's speed regulations. Simultaneously, the information of traffic violators is displayed in real-time on LED screens to notify and warn more vehicles. The interval speed measurement system conducts real-time monitoring and captures images of vehicles passing through the monitored area of the road checkpoint. It collects data such as the vehicle's speed, traffic flow, license plate number, color, approximate physical dimensions, and driver characteristics. This information is then transmitted via a network to the database of the public security traffic command center and the traffic control sub-center for data storage, querying, comparison, and other processing.
