Road accident may involve property damage, personal injury or even causalities. Dz The location in a road where highest number of road accidents occurs is called a Black Spotsdz The main objective of this study is to provide safe traffic movement, DzAccident are not Natural but they are causeddz is a common cliché in the area of traffic safety. This case study based on road accident of National Highway-86 which is from Sagar to Shahgarh (76km) of district Sagar (M.P.). A large number of accidents have been occurring over such a section of 76 km length because in this section have some hazardous location or accidental black spots. The accidents are due to human error and road parameters such as improper design of road section, bad shoulder, and design of junction, sharp curves and other factors. In this study attempts to identify the most vulnerable accident black spots using weighted severity index (WSI) methods and also provide suggestion for improvements of spots. The study includes collection of data and prioritizing the accident prone location by using weighted severity index (WSI) methods. WSI method follows a system of assigning scores based on the number and severity of accidents in that particular location in the last few years. So the main objects of this study identify black spots and improvement in it. Key Words: Accidental Black Spot, weighted severity index (WSI). 1. INTRODUCTION The problem of accident is very acute in Highway transport, due to complex flow pattern of vehicular traffic presence of mixed traffic and pedestrian, also due to human error or road parameters. Road accidents are the major cause of property damage, death and injuries worldwide. The basic elements in traffic accidents are road Users, vehicles, Road condition road geometry and environmental factor. Road accidents cannot totally prevent/stop, but by using suitable traffic engineering, management measure and better safety plan, so road accident rate can be decrease. According to The Ministry of Road Transport & Highway {MORTH}-2015, Road accident are now globally recognized as a serious public health problem, the problem much more serious in our country where dose to 5,00,000 road accident caused nearly 1,46,000 deaths and left more than thrice that number injured, during 2015. The numbers of vehicle are increase due to the growth of population and growth of Technology/Automobile, which cause road accident increase, the economic losses due to Road accidents in India are over Rs 100 billion per year. DzThe location in a road where the Traffic accidents often occur is called a Black spotdz. The Identification of location, analysis and treatment of Road accident black spots are widely regarded as one of the most effective approaches to road accident prevention. Black spots become a place on road that is considered to be dangerous because several accidents have happened there, Road accident happened their because of many reasons such as a sharp curves in a straight road, so oncoming traffic is concealed, if designs of junction are not proper on a fast road. Poor warning signs board at a road junction. Accident black spots can be improved by speed restrictions, Proper sign board and improving sightlines straightening bends etc. In Madhya Pradesh in last year 54947 accidents occur in which 9314 persons died and 55815 Persons injured in 2015. Road accident on National Highways has gone up by 3.2 per cent from 1, 37,903 in 2014 to 1, 42,268 in 2015, Persons killed on National Highways has also gone up by 7.5 per cent from 47,649 in 2014 to 51,204 in 2015. The major causes of road accidents are road condition and its parameter design are not good and also drunken drive careless/rush driving over speeding etc. The present study aims to identify accidental black spots on a section (sagar to shahgarh) of NH-86 by studying the accidental data provided by Police station during last five years. In this study identification of black spots by using weighted severity index {WSI} and Accident Density method {ADM} and during this study basic causes of accidents were found out and suitable remedial measures were also provided for a particular spots. 1.1 Scope and Objectives The objectives of the study can be given specifically as the following:- I. To collect Accident data regarding NH-86 (Sagar to Shahgarh 76 km) from concerned Police stations last five years (20012, 2013, 2014, 2015 & 2016).
