Skidmark Patterns and Identification of ABS-Equipped Passenger Car

[[abstract]]As Anti-Lock Braking System (ABS) was invented to solve the safety problem of tires’ lock-up caused by car braking in emergency, its control mechanism might causes the tire-marks produced by ABS car can not be distinguished precisely. This dilemma will distort accident investigation especially on marks and their’ identification. To solve this problem, we employ dynamic car-braking test, considering the influential factors on braking under administrable environment, to obtain tire mark observations. The testing results help us to clarify tire marks and develop suitable method to collect investigation data. Furthermore, based on the results, efficient methods on tire marks identification and measurement can be developed and greatly decreases investigation time
