Abstract:
During the last ten years. Accidents of vulnerable road users in Thailand have increased significantly and hit the most severe accident in 2017, especially teenagers between 15-19 year-old. When comparing to Japan in 2017, Japan has reached the lowest accident of all-time since 1960. Considering differences, there are differences in attitudes and behavior toward violation behavior. This study aims to analyze the factor affecting violation behavior between Thai and Japanese to determine the appropriate policies and recommendations. By studying road user's behavior and attitude based on the theory of planned behavior (TPB) in Bangkok, Thailand and Sapporo, Hokkaido, Japan. Questionnaires with road user violation behaviors were designed and developed for each country, and the surveys were conducted and distributed. The 201 samples in Japan and 477 samples in Thailand were collected, which have been valid responses. The validity and reliability of the questionnaire were evaluated. The data were analyzed by using the structural equation model (SEM). It was found that all of the models were significant. In Japan, the bicycle and the pedestrian model were used. Found that the most impactful factors of the bicycle model were notice failure and bicycle stun. Besides, for the pedestrian model were Instrumental attitude and conformity tendency. In Thailand, the motorcycle and the pedestrian model were used. The most impactful factors were traffic error and motorcycle stunt. For the pedestrian model were instrumental attitude, descriptive norm, and conformity tendency. It could be concluded that promoting the awareness of violation and accident by teaching the exact way to ride a motorcycle in detail and realize how they could decrease injuries and violations. However, in the community to prevent accidents, the community has to make the environment safe, build healthy communities and societies, give teenagers importance, and open up opportunities for adjustment. Lastly, the activities and promoting should emphasize parents and companions about the intention to violate the traffic rule. Moreover, cultivate consciousness in their own behavior.
