How does the laser ranging module monitor traffic flow?

Usually, this usage method involves fixing the equipment on a gantry on a highway or core road, with the laser transmitter and receiver facing vertically towards the ground and aligned with the center of the lane. When a vehicle is driving, the distance sensor can output the relative change value of the measured distance value in real time, thus depicting the outline of the motor vehicle.

This testing method usually requires a ranging range of less than 30 meters, and the requirement is that the laser ranging frequency is relatively high, reaching 100 hertz.

Compared to traditional traffic monitoring technology, laser sensor modules have the following advantages:

1. High precision: The laser ranging module can achieve considerable precision, reaching millimeter level measurement accuracy, which can better measure the distance and speed of vehicles, thereby improving the accuracy of traffic flow statistics and management.

2. Strong real-time performance: Distance sensors can achieve very efficient data collection and transmission, and can transmit the measured vehicle data to the traffic monitoring center in a very short time, thereby achieving real-time monitoring and management.

3. Small size of equipment: The Jingruite laser ranging sensor has a relatively small size of 43 * 25mm, which is easy to install and does not take up a lot of space.

4. Good stability: The ranging module adopts laser technology, which has high safety and stability, and can work in complex traffic environments without being affected by natural factors such as weather.

5. Strong programmability: The control program of the distance measurement module can be customized and programmed to process and analyze detection data according to actual needs, thus better meeting the needs of traffic management.

This can achieve good results for monitoring in core road sections, distinguishing various types of vehicles, with a sampling rate of up to 10 centimeters per point for scanning the height of the vehicle body, and real-time discrimination for vehicle height and length limits, motor vehicle classification, etc. It can also quickly output data.

When there are no motor vehicles arriving, the distance sensor measures a constant distance, which is also the distance from the distance sensor to the ground. When a motor vehicle passes under the distance sensor, the distance value changes. When the distance value returns to the constant again, it is considered that a vehicle has passed. According to this method, we can monitor the traffic flow passing through these road sections.

The commonly used method now is to statistically average the traffic flow over a period of time, which has a large estimation component. However, video statistical methods still have many practical difficulties in application. Therefore, laser ranging statistical methods provide a feasible solution for intelligent traffic monitoring of traffic flow.
