Road safety evaluation in Galle: towards star rating for Sri Lankan roads

Abstract

With the increase in transportation facilities, Sri Lanka has a high demand for the transportation sector. However, the existing road classification in Sri Lanka is challenging for people to judge their efficiency and safety. The standard of road classification needs to be self-explanatory with its infrastructure standard and road safety, in Sri Lanka that can be accomplished by performing a road safety evaluation. This study contributes to the improvements of the prevailing safety assessments regarding roads in Sri Lanka to the required standard. This can be performed through a road star rating system for Sri Lankan roads which may be based on the International Road Assessment Program (iRAP). The road star rating analysis would assist in locating high-risk areas on the Sri Lankan Road network and prioritizing safety measures to enhance the performance of the roads in terms of safety. The methodology entails gathering and evaluating data on the road network for the purpose of assessing the safety performance of roads using a star rating system. The data collection was done through the Google Earth Pro software, for 30 selected road segments in the Galle district. The analysis of the results will provide insight to identify the relationship that exists between the number of road accidents and the other roadside variables.
