This study includes the factors which contribute to road accidents and effective measures to reduce the occurrence of accidents. The traffic engineer makes an important contribution to better design and control of the road system. Bangalore is the city comes in fourth position from the top 10 cities with the highest number of Road Crash Deaths (in India). In this, accident data s are used to identify black spots and traffic studies are used to find the improvements in geometrics of road. The accident data can be obtained from First information Report (FIR). Collected data s are classified in to Location, Fatal/ Grievous injury accident details of three consecutive years, Type of collision, Type of Vehicles Involved, No. of Vehicles Involved. The identified spots can be investigated with traffic volume studies to identify the improvements. 2. REVIEW OF LITERATURE Neha Bhangria et al. (2017) had done a paper on Review on black spot study of highways in India. Indian highways are surged more than 400% from 2001 to 2013, but in case of National Highways it grown only 133%. This is the major cause of accidents and congestion in India. The other important features for the Causes of the accidents are over speeding, unavailability of service roads in built up areas, absence of pedestrian crossing and cyclist paths along the road, absence of lane marking, warning sign boards, speed breakers, the traffic rules and not following. Remedies for the issues are use of intelligent transportation system (ITS), enforcing strict laws against breaking the traffic rules, providing proper road marking. Snehal U Bombade et al. (2015) studied on Identification of accidental black spots on national Highways and Expressways. In this study, the parameters, those are responsible for the accidents are considered followed by a field survey. The field survey will gives the factors which affect the road and hazardous locations. In this paper author considered 10 parameters and it is ranked from 1 to 10 for each chainage. The most important parameter will get minimum rank. From this method black spots are identified, but a separate investigation is necessary for safer sides. Nikhil T R et al. (2013) studied on Identification of Black spots and improvements to junctions in Bangalore city. Goraguntepalya, Jalahalli are the two junctions (Black spots) considered in bangalore city for the analysis. From the classified datas of accidents and traffic volume; remedial measures are suggested. The condition of road, inadequate light in night, negligence of driver, absence of pedestrian crossing, speed brake, road hump are the main issues faced in the study area. Repairing of cracked surface, filling up of pot holes, installation of cat eyes in the junctions, provision of underpass or skywalk for the pedestrian, provision of road humps before the pedestrian signals etc are the remedial measures suggested by the authors. Mehul Hinsu et al. (2015) studied on Black spot identification and Remedial Measure for Accident in Ahmedabad city. In this case study, Black spots are identified based up on the accidents recorded and remedial measures are given for reducing accident at each black spot. From the literature study, Author describes that there are five methods for identifying hazardous locations. They are (1) The accident frequency method, (2) Accident rate method, (3) quality control method, (4) Accident severity method, and (5) combined method. The paper also states that, improving safety on roadway can be achieved through further improvements in vehicle safety, improvements in driver, pedestrian etc. But the results are classified not as per the priority or location editor@iaeme.com

3 Prioritization of Black Spots In East Bangalore & Improvements of Geometrics To Black Spot In Outer Ring Road 3. OBJECTIVE OF STUDY Discussion on methodology to identify Black spots To Identify the Black spots of the Bangalore city ( East Division) To investigate the existing accident patterns at identified Black Spot To suggest Improvements in terms of road geometrics for Black spots identified (Using traffic studies) To simulate existing as well as proposed improvements using PTV Vissim (student) 4. METHODOLOGIES TO IDENTIFY THE BLACK SPOTS Generally four methods are used to identify the Black spots Weighted Severity Index Using Geographic Information System Method of Ranking Based on accident recorded on Police Stations 4.1. Weighted Severity Index WSI = (41* K) + (4*GI) + (1*MI) Where, K is the number of person killed GI is the number of grievous injury MI is the number of minor injury Locations having WSI above 40 are termed as accident black spots. This method can also use to rank the black spot for prioritization Using Geographic Information System Kernel Density Estimation Using Arc GIS It is a Spatial analysis method Used to calculate the density of accidents with a search radius of 50m It divides the entire study area to a pre-determined number of cells and applies a circular neighborhood around each crash Density Estimation measures cell densities in a raster by using a sample of known points Kernel function will centering at a known point and tampering of to 0 over a defined window area The black spot is detected in dark blue color for heavy vehicles and dark red for light vehicles editor@iaeme.com

Afif Salim, Agus B Siswanto, Dhony Priyo Suseno with Purwantini Point Density Estimation Fig output using kernel density method It calculates the density of point features around each output raster cell A neighborhood is defined around each raster cell center, and the number of points that fall within the neighborhood is totaled and divided by the area of neighborhood 4.3. Method of Ranking Fig output using point density method Collect accident data from Police Stations Identify various traffic and road related factors Analysis of black spots by using statistical models Detailed analysis of the top ranked spots editor@iaeme.com

5 Prioritization of Black Spots In East Bangalore & Improvements of Geometrics To Black Spot In Outer Ring Road 4.4. Based on accident recorded on Police Stations The accident data can be obtained from First information Report (FIR) Collected datas are classified in to Location Fatal/ Grievous injury accident details of three consecutive years Type of collision Type of Vehicles Involved No. of Vehicles Involved From the classified data, five road accidents took place during the last three consecutive Calendar years involving fatalities/grievous injuries or Ten fatalities took place during the last three consecutive calendar years (As per Karnataka Govt Order, Dated 4/4/2017) 5. IDENTIFICATION OF BLACK SPOTS From the FIR (first information report) copies of three consecutive years (2016,2017, 2018), Five road accidents took place during the last three consecutive Calendar years involving fatalities/grievous injuries or Ten fatalities took place during the last three consecutive calendar years are considered to identify the black spot. Following are the Black spots in Bangalore East Division.

RESULTS AND DISCUSSION Figure 8. 2 Proposed condition The Black spots in the Bangalore city was identified using traffic accident data. Later, the identified spots are prioritized by WSI method. Most of the prioritized black spots are concentrated nearer to the bus stop From the studies it came to know that, most of the victims of accidents are pedestrians and major accidents are happening due to ignorance of driver Provision of skywalk/underpass to pedestrians, additional lane in case of congested volume, informatory and warning boards aside of road, restriction of parking in the road side, provision of lighting system are major improvements proposed for the black spots PTV Vissim (student) version was used for simulating the real and improved spots. The results proves the necessity of improvement in terms of geometrics Since the PTV vissim (student) version have less features, several improvements are not done for simulation 10. CONCLUSION The identification and analysis of accident black spots help in identifying the stretches were accidents are more and these spots reduce the road safety in general. The spot on the road were traffic accidents frequently occur is termed as black spot The WSI (weighted severity index) method was used to rank the accident locations. The top ranked spot were selected and suggested some possible alternative measures to improve the transportation system The overall methodology was found to be effective for the identification, evaluation and treatment of accident black spots Implementation of the suggested improvement will help to increase the overall road safety and provides convenient travel for the road user editor@iaeme.com
