Accidentseverity is increasing in increasing order due toincreasing in vehicle population.Accident leadsto disablement,death,damage to health andproperty,social suffering and generaldegradation of environment.The main cause ofaccidents are the driver,vehicle and roadenvironment.Generally accidents occurs atintersection where low volume traffic mixeswith high speed traffic.The location in aroadway where the traffic accident often occuris called a blackspot.A case study was taken onNH-55 of angul district in Orissa state.The mainproblems on this road are obstructionvisibility,badshoulder,trees and poles on theshoulder.Thedefiencies were analysed toimprove black spotKEY WORD-Accident Severity,NH-55,BlackSpotA.INTRODUCTIONTo minimize the no of crashes by any kindand severity expected to occur on the entity duringa specific period is known as road safety.Accidentsandthefatalitiesonroadaretheresultofinter-playofanumber offactors.Road usersinIndiaare heterogeneousinnature,rangingfrompedestrians,animal-drivencarts,bi-cycles,rickshaws,handcartsandtractor trolleys, tovariouscategories oftwo/threewheelers,motorcars,buses,trucks,and multi-axlecommercialvehiclesetc., The vehiclepopulation has been steadily increasing becauseofchangeinthestyleofliving ofpeople. Increaseinvehiclepopulationwithlimitedroadspaceusedbyalargevarietyofvehicleshasheightened theneedandurgencyforawellthought-out policyontheissueofroad safety. InIndiatherate ofaccidentisdirectly proportionaltogrowthofvehiclepopulation.B.IDENTIFICATION OF BLACKSPOTSItistheproceduretolocatethosespotsintheroadnetwork thatareparticularlydangerous.Thisstudydealswiththeprocedureforidentificationofhazardouslocationsorblackspotsastheyareoftencalled.Theproceduredescribedisbasedonrecordedaccidents,dataaboutaccidents,trafficvolumesandvehicle-kilometers. Othermethodsusedarefieldinvestigations,conflictstudies,questionnairesandinterviews,etc.Identification is a first step inimproving road safety at a black spot. It has tobe followed by diagnosis of the selected spots,finding countermeasures, estimating effects andcosts, prioritizing, implementation and at lastfollow-up and evaluation.In India 5 lacs road accidents occurs every year and1.5 lacspepole are killed. This is a great problemfor our country as 3% GDP are lost financialy andmany precious lives are lost.Accidents are notnatural but human tragedy.Hence road safety is amajor concern.In Orissa angul and keonjhargarhhas the highest no of accident due to industriesbased on coal and iron respectively.Study stretchwas taken from Angul to Bhushan steel plant asit is surrounded by no of heavy industries like-Jindal,Nalco,Brg,Monnet,GaneshSponge,Navbharat Ferro alloys,Gmretc.Accidentdatas werecollected from police stations and analysed tostudy black spots.C.OBJECTIVE AND SCOPE OF THEWORKThe whole stretch was divided in to fourstretches.The accident data collected for the lastten years and to derive improvementmeasures.The study objectives include,1.Identification of suitable black spot2.Ranking of the identified black spots3.Detailed analysis of top ranked spots andsuggestion of possible improvementBLACK SPOT IDENTIFICATION ANDANALYSISStudy StretchNH-55 passing through angul city was selectedfor this study as shown in fig 1.

Speed limit should bebrought down by providing humps near accidentspots. Sight distance near curves should beobstruction free.(2)Stretch I has the second highest no of accidentsaccounts for 32.5% of total accident. The accidentrate can be reduced by providing signalizedjunction, junction improvement, shoulderclearance, 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 beminimized by clearing-off shoulders, reducingspeed limit, junction improvement, providingsignals on the median, removing structures on theshoulder.(4)Stretch III has minimum no of accidentsaccounts for 3.7% of total accidents. speed limitreduction near junction should be reduced toprevent accidents.REFERENCES1.Hiselius(2004)Estimatingtherelationshipbetweenaccidentfrequencyandhomogeneousandinhomogeneoustrafficflows,AccidentAnalysisandPreventionvol.36pp.985–9922.
