TLDR
A novel method of detecting the moving direction of a vehicle using only one sensor unit using a 2-axis magnetic sensor, low cost microcontroller, and signal processing technique is proposed.Abstract:
To improve the efficiency of the intelligent transportation system, the study on the detection of speed and moving direction of a vehicle has been researched recently. Conventional method to detect the moving direction of a vehicle is to use two separate sensor units under vehicle road, which results in expensive cost and long installation time. In this research, a novel method of detecting the moving direction of a vehicle using only one sensor unit is proposed. The newest magnetic sensor is multi-axis detectable and occupies very small space. The proposed detection scheme uses a 2-axis magnetic sensor, low cost microcontroller, and signal processing technique. The designed sensor for detection of the direction of a vehicle is easy to install and less expensive than other type sensor. Experimental results showed that the proposed algorithm sensor was very effective and reliable.read more
