Post-crash Response Factors for Road Traffic Transport in the Eastern Economic Corridor of Thailand

Road traffic crashes can have severe consequences including death, making it essential to manage post-crash responses effectively. The aim of this study was to identify indicators and main factors that support post-crash response management within Thailand’s Eastern Economic Corridor that includes the provinces of Chachoengsao, Chon buri, and Rayong. Each province faces challenges with a high number of fatal and serious crashes, especially during holiday periods (Chachoengsao); frequent collisions due to heavy tourism and industrial traffic (Chon buri), and a rise in crashes, especially in industrial zones and densely trafficked areas (Rayong). The study was conducted in two phases. The first phase was a content analysis of the academic literature, alongside a review of secondary data from government and international reports related to post-crash responses. The second phase was a survey of professionals involved in road traffic incidents (n=196). Responses were analysed using Exploratory Factor Analysis (EFA) to identify and validate the factors informing post-crash response indicators. The findings identified 25 indicators grouped into two factors: Post-Crash Response Information (PRI) and Post-Crash Injury Care and Legislation Support (PRILS) that were used to create a framework to manage and improve the post-crash response. Post-crash response includes prompt assistance as well as preventing secondary crashes, saving lives, treating injuries, and ultimately reducing road traffic crashes. This approach contributes to improving the efficiency and effectiveness of post-crash response systems in alignment with international standards for road safety management.
