Road traffic accidents are the tragic artificial disease which more than thousands of people injured and dead each year. The Thai government has alert and implemented 5-E strategy to tackle the problems. However, owing to the inaccurate road accident statistics and the inefficient data collection method on causation and collision particularly, on potential and existing black spots, these are major obstacles to improve road safety. This paper investigates the possibility to introduce Hiyari-Hatto method to identify and collect data on existing and potential black spot locations. 200 local peoples who live in Soi Chokchai 4 and Soi Ladprao 39 communities in Bangkok were participated in the interview survey. The findings indicated Hiyari-Hatto method is a significant alternative method for public participatory enhancement to develop black spot database nationwide.
