Applying GIS Analytics and ADAS with DMS to Assessment Heavy-Duty Vehicles Unsafe Acts and Unsafe Conditions in Thailand

The study by the World Health Organization (WHO) reveals that Thailand has the highest road traffic death rate in Asia. Based on the data obtained during 2019–2021, heavy duty truck vehicles (HDVs) had steadily tended to have an accident, causing more economics losses than others. While the statistics lead to a question whether those accidents were caused by reckless road usage or other possible causes, existing studies cannot accurately explain as they were conducted from interviews with offenders and witnesses. Those studies also did not take topography into account while it is indeed different in Thailand, leading to errors in analyses and incorrect solutions. Hence, this study aims to identify and analyse factors from both the actions of drivers and environment. The researchers use GIS to accurately conduct both spatial analysis and locational analysis while taking the factors of the routes whether they are inbound or outbound, the unsafe environment in each region and the data of driver fatigue obtained by using ADAS with DMS into consideration to supplement the existing studies. The researchers expect the analysis to be fully utilized by related authorities to improve unsafe conditions and form a strategy to manage and reduce accidents.
