A Node Design for Intelligent Traffic Monitoring Based on Magnetic Sensor

In order to meet the real-time demand of the intelligent traffic system for traffic information, this paper have presented an intelligent traffic monitoring method based on magnetic sensor, and have analyzed the principles of magnetic sensitive detection and wireless node design, and have developed a practical detection node. Based on experimental test, the success rate vehicle detection is over 95%, and can avoid the iteration count of vehicles. We also have carried out on the speed and length measurement. The results show that the designed node can meet the demand of intelligent transportation system of the vehicle flow, vehicle speed and length parameters real-time monitoring needs. The test results show that the intelligent traffic monitoring method based on magnetic sensor has high accuracy, low cost, easy to deploy, and provides a new practical method and solution for intelligent transportation system.
