Vehicle Safety Monitoring System with Next Generation Satellite Navigation: Part 2 Excessive Acceleration Detection 2015-01-0124

The road accident is major concern around the world, so do Thailand. It is caused by three main factors: man, vehicle and infrastructure. The most important part that accounts the safety of vehicle is human. With experiences and careful driver, the accident could be diminished. So that the vehicle monitoring systems are the vital tools to screen out the inexperience or aggressive driver.
In this paper, we state the problem about the dangerous driving behavior by monitoring lateral and longitudinal acceleration. For this purpose, the inertial measurement unit should be applied but it is inconvenient to install in the vehicle. Consequently, the vehicle monitoring system were developed based on novel consumer grade multi-satellite navigation receivers and were compared to Racelogic Video V-Box system in controlled condition tested track. The incidents were virtually detected and reviewed. The incident detection algorithm were proposed and tested alongside with receivers.
As results, the vehicle lateral and longitudinal acceleration from all receivers were correlated with virtually count. With incident detection algorithm that cut off at 0.25g in both directions were detected and the number of incidents were same as references.
