The Effectiveness of Temporary Traffic Calming Devices on Reducing Speeds of Traffic Flow in School Zones

Safety issue in school zones is one of the momentous problems in Thailand; in which mostly, the passing vehicles are often negligent to decelerate their speeds when entering to school areas. Chiefly, during the schools opening and closing times in a day, a number of students are usually staying in front of such schools. Henceforth, the effort of this study contributes to seek the efficient form of temporary traffic calming device to substantially decrease speeds of traffic flow. The study carried out the examination of three types of temporary traffic calming devices on assumption that they efficiently moderate speeds of traffic flow through the actual test at school zones in Rayong Province where a greater number of accident statistics were recorded. The findings evidently stated that two types of temporary traffic calming devices were suggested in effectively reducing speeds of traffic flow with statistical significance.
