Abstract

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

Highlights

  • Speed is considered as a meaningful factor to road safety issues

  • If considering factors that affect crash occurrence based on Clarke et al.[4], it indicated more than 65% of number of accidents was caused by driving over the speed limit

  • The study applied purposive sampling and selected the study area of rural schools established in adherence to ­two-­lane roads at Rayong Province based on the rationale that when considering accident statistics reports, the Rayong Province showed the greater severity of crashes, in that 148 deaths, 72 serious injuries, and 117 minor injuries from 250 accident cases were recorded in B.E.2554 (2011) [14]

Summary

Introduction

Speed is considered as a meaningful factor to road safety issues. Based on Somchainuek et al.[15], vehicle speed was accounted for 70% of the leading causes of road accidents in Thailand. If considering factors that affect crash occurrence based on Clarke et al.[4], it indicated more than 65% of number of accidents was caused by driving over the speed limit. The study of Richter ED [13] relating to speed limit pointed out if the speed limit is raised by 10 km/h (from 90 km/h to 100 km/h), the number of fatalities on roads will go up to 15% or increase from 46% (90 km/h) to 61%(100 km/h). This study endeavors to deter speed rates of passing cars close to the speed limit
