Development of road accident prevention Ssystem: a case study of kamsakasang junction, Non-Thai District, Nakhon Ratchasima Province

Abstract

This research aims to develop a road accident prevention system to reduce the risk of accident, a case study of Kamsakasang Junction, Non-Thai District, Nakhon Ratchasima Province. The target audiences are: traffic experts and 15 civil engineers to evaluated the developed system. From the study of traffic problem and risk areas, there are 7 aspects to be improved: 1) Installation of traffic light, 2) Installation of lighting and changing control cabinet, 3) Improvement of the traffic island, 4) Changing lower traffic island to higher one, 5) Painting reflecting colour and reflecting light on the edge of the island, 6) Drawing traffic line, 7) Installation of warning signs. From the development of accident prevention system and evaluated by the experts; the overall evaluation of the system was the best (x = 4.66, SD = 0.41). There were 6 highest rated aspects and 1 very good aspect. The highest rated were installation of Vehicle Actuated traffic light (x = 4.92, SD = 0.15). As result of the development of road accident prevention system in 2014, the accident statistics were reduced by 53.85% compared to the pre-installation period. The statistics are reduced, so it can be concluded that the road accident prevention system can be used effectively and it can be applied to other risk areas.
