Khode Department of Civil Engineering G H Raisoni College of Engineering, Nagpur 440016 Abstract Though comprehensive road safety plans have been formulated which focus on education, enforcement measures and emergency care, there is a lack of sound and rational engineering measures to improve the road safety in our country. This paper aims to analyze, evaluate and identify effective road safety treatment measures for a rural national highway. The study area will be the national highway- 6 connecting Nagpur to Kondhali. Accident data of past 3 to 5 years will be collected for the analysis. Basic aim of this study will be articulate, carry out complete analysis of crash data, and identify the critical stretch in the national highway which would require immediate safety improvements. Critical sketch is identified. This could aid the highway safety audits in country for identifying specific regions in national highways depending upon the geometric element which is aimed to improve as part of safety improvement programs. Similarly a crash prediction model is developed which will be correlating the number of accidents and parameters like lane width, shoulder width, average daily traffic and number of junctions in divided sections. Keywords: Crash causes, data, critical sketch ________________________________________________________________________________________________________ I. INTRODUCTION Crash prevention and control is on the 4 E's, a fifth E is gaining popularity in road safety studies worldwide. This fifth E is evaluation and it broadly aims at assessing the road safety using safety performance indicators. Such indicators are reliable, simple and efficient tools for comprehensive road safety analysis. Though comprehensive road safety plans have been formulated in India that focus on education, enforcement measures and emergency care, there is a lack of sound and rational engineering measures to improve the road safety. II. PROCEDURE The main data requirements for the evaluation purpose will be: 1) Accident data 2) Geometric Features 3) Spot Speed Accident Data: The accident data required for the study is collected from the records of the police which are being collected as a part of a National Highway Authority of India (NHAI) project with the following particulars: - Accident location - Accident date and time - Nature if accident - Classification of accident - Cause of accident - Road features and road condition at the spot - Weather condition at time of accident - Intersection type and control - Number of person affected as per the injury (fatal, major, minor) Geometric Features: The geometric features of the road is collected for the development of correlative analysis. Carriageway width, shoulder type, shoulder width and condition will be needed to be evaluated.
