Thung Khru District’s Road Safety action and coordination at curve, Soi Pracha Uthit 119

Abstract

This research aims to study road safety action and coordination problems for mitigating road accidents by using accidents at the horizontal curve section near Soi Pracha Uthit 119, Bang Mod, Thung Khru, Bangkok as a case study. At the site, there were two motorcycles departing the curve twice within four months. The first accident occurred on December 2^nd, 2021. Therefore, many officers needed to come together to analyze the cause of the accident in order to find a solution to the problem. Unfortunately, on March 16^th, 2022, a similar accident occurred again before the problem had been fixed. The causes of these two accidents were the motorcyclists themselves, the geometry of the roadway curve, a lack of traffic control devices, and insufficient roadway lighting. We found that there was only basic investigation, and therefore the problem would not be solved urgently. This case study would be used as a guideline for road safety action plan and coordination to other organizations
