Rider Injuries of Scooter – Passenger Car on Various Types of Collisions Based On PC-Crash Simulations

Motorcycles (MCs) are a prevalent mode of transportation in Thailand, constituting over 50% of registered vehicles, with the majority being underbone and step-through types. However, MC accidents pose significant road safety challenges, contributing to a high rate of injuries and fatalities. This study evaluates rider injuries in scooter-passenger car collisions through PC-Crash simulations, addressing the urgent need for MC test protocol specific to Thailand. Adhering to the ISO 13232-8:2005 standard for crash conditions, various collision scenarios were simulated to focus on head and chest injuries, evaluated using the Head Injury Criterion (HIC) and chest deceleration measurements, respectively. Results indicate significant variability in rider kinematics and injury patterns across different impact scenarios, highlighting severe head and chest injuries in direct perpendicular impacts. The study underscores the importance of adaptive safety measures tailored to specific collision scenarios and advocates for further research integrating real-world accident data to enhance the effectiveness of safety strategies in reducing motorcycle-related injuries and fatalities in Thailand.
