Collisions between pedestrians and city buses are one of the severe casualties in Thailand. This research aims to develop an assessment program and to evaluate the front end of public city buses based on pedestrian injuries and mechanisms in Thailand. Therefore, vehicle preparation and marking, testing conditions, and HIC requirements, assessment criteria, and road map suggestions are studied for the development of the bus assessment. A grid will be marked on the outer surface of front-end of the city buses in terms of vehicle preparation and marking. The determination of grid size and grid location should refer to real-world accidents. Grid locations are defined based on anthropometric data. Testing conditions were identified by the realworld accidents in a preliminary study and also the Head Injury Criterion was adapted in the assessment. Moreover, chest and leg zone test information should be combined to improve the rating scores in future work.
