What does interval speed measurement mean?
2 Answers
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.
Interval speed measurement is like assigning a math class representative to the highway—it sets up monitoring points at both the start and end of a road section to calculate how long your car takes to traverse the entire stretch. For example, on a 30-kilometer speed-limited section, the minimum required time is 24 minutes. If you finish it in just 20 minutes, that’s definitely speeding! This mechanism specifically targets those 'clever' drivers who slam on the brakes before regular speed cameras. Now, it’s being widely implemented on highways nationwide, and navigation apps will give advance warnings. But the safest approach is still to keep your speed within the limit throughout the entire stretch.
