Electronic Tracking Device of Mass Public Transport Vehicle for Evaluating Driving Performance in Thailand

Abstract

Thailand Mass Public Transport has a location tracking device along with a vehicle speed limiter attached to each public transport vehicle combined with Mass Public Transport Policy that aims to prevent dangers caused by improper driving behavior. These actions result in the troubles caused by inappropriate driving behavior decreasing drastically. However, risks from driving have more cases that the vehicle’s position and speed cannot determine and analyze. Thus, this research aims to develop a data-collecting device that collects linear acceleration, angular velocity, and magnetic field while transmitting data to an online database. The collected data enables the creation of a three-dimensional simulation from ten different public transport vehicle routes. The two main goals of developing a data-collecting device are to maximize the data collection frequency and evaluate its effectiveness in a real environment while the public transport vehicle is on duty. From ten vehicle routes, the device was able to collect stable data at a frequency of 50 Hz, with a reliability rate of over 50%. However, the device encounters various problems from external factors and bus layout diversity while testing in real environments on the road, which have been solved and are ready for real usage and statistical data analysis in the future.
