Initial conceptual matrix on the development of Road Safety Assessment Tool (RSAT) for new road project

Abstract

There is an absence of self-assessment tools to determine the level of safety at the design stage of road projects in Malaysia. This paper is presented with the intention to develop the road safety assessment tool by determining the level of safety for new road design project. For this study, the conceptual matrix was initially constructed by focussing on the geometry design elements, based on various literature and precedent research. To initiate the tool, five (5) elements of road assessment were addressed in the matrix; i) sight distance, ii) design speed, iii) traffic signal, iv) cross section (surface type); and v) horizontal alignment. The initial conceptual will be a pre-basis guidance for the next phase of main survey. Road Safety Assessment Tool (RSAT) will be indicated as guidance towards the design element of the road that contributes greatly to the safety impact. It is expected that RSAT can be used as a complementary tool to assist in the implementation of Road Safety Audit. It is hoped that this study will provide a model for local agencies nationwide to implement road safety audit recommendations more effectively.
