The traffic signal light consists of red light, green light and amber light. The red light indicates no passage, the green light indicates permission, and the amber light indicates warning .  When the green light is on, vehicles are allowed to pass, but turning vehicles shall not hinder the passage of straight vehicles and pedestrians. When the amber light is on, vehicles that have crossed the stop line can continue to pass, which is not regarded as running the amber light.   For the amber light is on when the motor vehicle decelerates through the intersection, the motor vehicle that has crossed the stop line can continue to drive, and the motor vehicle that has not crossed the stop line shall stop. H owever, running the amber light is a violation of the road traffic signal, the driver shall be fined not less than 20 yuan but not more than 200 yuan, and 6 points shall be deducted.   Identification of amber light: the driver should slow down before preparing for the amber light.

Geomagnetic sensors can be used to detect the presence of vehicles and vehicle type recognition. The data acquisition system plays a very important role in the traffic monitoring system. The geomagnetic sensor is a key part of the data acquisition system. The performance of the sensor plays a decisive role in the accuracy of the data acquisition system. Geomagnetic sensors  can be used to detect the existence and model of a vehicle. It uses the influence of the earth's magnetic field when vehicles pass the road to work. And this kind of sensor is very compact and convenient, the sensitivity is also first-class, the construction amount is very small, but its service life is very long, and the damage to the road surface is also very small. 1. The working principle of geomagnetic sensor in parking service The geomagnetic sensor is the front-end sensing device of the ground guidance system, which can accurately lock the stay and departure time of the vehicle. And transfer these data to
