Accident severity is increasing in increasing order due to increasing in vehicle population.Accident leads to disablement,death,damage to health and property,social suffering and general degradation of environment.The main cause of accidents are the driver,vehicle and road environment.Generally accidents occurs at intersection where low volume traffic mixes with high speed traffic.The location in a roadway where the traffic accident often occur is called a blackspot.A case study was taken on NH-55 of angul district in Orissa state.The main problems on this road are obstruction visibility,badshoulder,trees and poles on the shoulder.Thedefiencies were analysed to improve black spot KEY WORD-Accident Severity,NH-55,Black Spot A.INTRODUCTION To minimize the no of crashes by any kind and severity expected to occur on the entity during a specific period is known as road safety. Accidentsandthefatalitiesonroadaretheresult ofinter-playofanumber offactors.Road usersinIndia are heterogeneous innature,rangingfrompedestrians,animal- drivencarts,bi-cycles, rickshaws,handcartsandtractor trolleys, tovarious categories oftwo/threewheelers,motor cars,buses,trucks,and multi- axlecommercialvehiclesetc., The vehicle population has been steadily increasing because ofchangeinthestyleofliving ofpeople. Increase invehiclepopulationwithlimitedroadspaceusedbya largevarietyofvehicleshasheightened theneedand urgencyforawellthought-out policy ontheissueofroad safety. InIndiatherate ofaccident isdirectly proportional togrowthofvehiclepopulation. B.IDENTIFICATION OF BLACK SPOTS It istheproceduretolocatethosespotsintheroadnet work thatareparticularlydangerous. Thisstudydealswiththeprocedureforidentificationof hazardouslocationsorblack spotsastheyareoftencalled.Theproceduredescribedi sbasedonrecordedaccidents,data aboutaccidents,trafficvolumesandvehicle- kilometers. Othermethodsused arefieldinvestigations,conflictstudies,questionnair esandinterviews,etc.Identification is a first step in improving road safety at a black spot. It has to be followed by diagnosis of the selected spots, finding countermeasures, estimating effects and costs, prioritizing, implementation and at last follow-up and evaluation. In India 5 lacs road accidents occurs every year and 1.5 lacspepole are killed. This is a great problem for our country as 3% GDP are lost financialy and many precious lives are lost.Accidents are not natural but human tragedy.Hence road safety is a major concern.In Orissa angul and keonjhargarh has the highest no of accident due to industries based on coal and iron respectively.Study stretch was taken from Angul to Bhushan steel plant as it is surrounded by no of heavy industries like- Jindal,Nalco,Brg,Monnet,GaneshSponge,Navbha rat Ferro alloys,Gmretc.Accidentdatas were collected from police stations and analysed to study black spots. C.OBJECTIVE AND SCOPE OF THE WORK The whole stretch was divided in to four stretches.The accident data collected for the last ten years and to derive improvement measures.The study objectives include, 1.Identification of suitable black spot 2.Ranking of the identified black spots 3.Detailed analysis of top ranked spots and suggestion of possible improvement BLACK SPOT IDENTIFICATION AND ANALYSIS Study Stretch NH-55 passing through angul city was selected for this study as shown in fig 1.

Speed limit should be brought down by providing humps near accident spots. Sight distance near curves should be obstruction free. (2)Stretch I has the second highest no of accidents accounts for 32.5% of total accident. The accident rate can be reduced by providing signalized junction, junction improvement, shoulder clearance, installation of humps, shifting of poles , removal of trees near the edge of pavement etc. (3)No of accidents in stretch II accounts for 29.6% of total accidents. The accident rate can be minimized by clearing-off shoulders, reducing speed limit, junction improvement, providing signals on the median, removing structures on the shoulder. (4)Stretch III has minimum no of accidents accounts for 3.7% of total accidents. speed limit reduction near junction should be reduced to prevent accidents. REFERENCES 1.
