| Abstract | This study presents the development of the Accident Information System (AIS) in the selected study area, Khon Kaen, Thailand. Unlike other previous studies which utilize the available traffic accident data to achieve their optimal goal, this research, on the other hand, attempts to develop the non-existence database system and then links with the existing system to achieve the optimal results. Additionally, AIS is also designed to incorporate both objective and subjective methods. The former is based on the historical accident data through the integration of police and hospital data. The latter is the extent of experiences shared by road users through the proposed Accident Public Participation Program (APPP). Since each method has its merits and pitfalls, their merits are combined to design the AIS comprehensively, effectively, and efficiently. To achieve these desired objectives, firstly, the computerized traffic accident database for the Khon Kaen Police Station is developed in this study. The three-year police accident recorded data are extracted and transferred into the developed computerized database. Accident situations both for spatial and non-spatial point of views are revealed in the study area. In addition, the development of an advanced tool to facilitate accident datacollection and analysis processes is also addressed. An integration of three advanced technologies including hand-held computers, GPS and GIS is proposed. Under the proposed concept, the hand-held computer plays a major role in recording non-spatial data, while the main function of GPS is a spatial data collector. Lastly, GIS which is a versatile database management tool, is employed to perform several tasks such as data retrieval, data analysis, and information distribution.. On the other hand, the APPP is developed to provide the accessibility for public/road users to inform/report any black spot or potentially dangerous location according to their perception and experience. This approach is the first of its kind in Thailand to involve public participants in identifying black spot locations. Its methodology and validation processes are highlighted through the case study. The feasibility, validity, and effectiveness of the program are evaluated by comparing the findings obtained from the proposed framework and those obtained from the classical approach in this field. The comparison results indicate that there are statistically significant agreements between the public input data and historical accident data. Therefore, it can be concluded that the proposed method can be used as a supplementary tool to identify the black spot location especially for the areas where the accident data is degraded, limited, or not available. This research, finally, reveals three real world applications of the developed AIS. These include the application to determine the extent of under-reporting problem, the application to identify the black spot locations in the study area, and the application for the Emergency Medical Service System (EMS) |
