SAMRAT ASHOK TECHNOLOGICAL INSTITUTE Department of Civil Engineering S.A.T.I. Vidisha, M.P. TOPIC – Literature Review on Road Safety Audit During Night. By- Ritik Tiwari ROAD SAFETY AUDIT ON EXISTING ROAD REPORT NO. 1 MOHAMED RAMIS N [DR MGR UNIVERSITY, CHENNAI] • SCOPE – 1. To reduce the risk of injuries 2. To reduce the Fatal & Severity 3. Road Accident Analysis of Projects Roads of Past 3 Years based on First Information Report (FIRs) 4. To growth consciousness about safe design practices among all those involved within the planning, design, creation and Maintenance of roads. • Site Location – The site starts from 11km to 54km in NH-16 [Old NH-5] in the state of Tamil Nadu. • Year of Study- June 2020. • CASE STUDY - 1. Data Collection and Formatting- The accident data which were collected and reported for the Project stretch i.e. Chennai to Tada section of NH-05. Accident Data was collected for the period January 2013 to December 2013. 2. Crash Analysis- The main purpose of crash analysis is to improve safety for the road users by identifying crash patterns, mitigating crash severity, analyzing the causes for the accidents and to recommend suitable safety measures to eliminate accidents and to provide a safe, comfortable journey within a reasonable time. • Methodology for Identification of Black Spots * The location where the expected number of accidents are higher than at other similar locations as a result of local risk factors. * The accidents will be grouped into 4 main types based on their Severity. The Four Types are: 1.Fatal Accidents 2. Grievous Injury 3. Minor-Injury 4. Non Injury. • Summary of Findings: 1. Three Hundred and Sixty-Two (362 Accidents) has occurred in the project corridor between Chennai to Tada (CH 11.000 to CH 54.400) during the period January 2013 to December 2013. 2. 6.9 % of total accidents are Fatal Accidents,33.7% of total accidents are Grievous Injury Accidents,30.4 % of total accidents are Minor Injury Accidents and 29.1% of total accidents are Non-Injury Accidents. 3. No barricade over the median in this portion. Pedestrians are crossing at this location. 4. Poor visibility and insufficient turning radius for vehicles coming from minor road. 5. Poor visibility for the vehicles coming from the Service Road of the flyover. No Hazard marker. • CONCLUSION - o Almost all the accidents have occurred in the Straight stretches of the Road, where the drivers are tempted to go at high speed. Hence necessary sign boards have to be provided to regulate the speed and the same should be enforced. o Provide rumble strips, groove pavement etc., to regulate the speed at intersections / median openings as majority of accidents have occurred due to Drivers negligence. REPORT NO .2- ROAD SAFETY AUDIT: A CASE STUDY ON NH-65 [TUMMALA BHARAT KUMAR] Objectives- To assess Road Safety of National Highway [NH-65, previously NH-9] of India. Identify designing imperfections and recommend intercessions. Identification of accident prone regions on the highway. • Site Location- The site is from 247km to 270km I.e. from Donabanda to Vijayawada, A.P. • Year of Study – 2018 • Accident data - The accident data is collected from the national highway authorities from stretch Vijayawada to Nandigam. The data collected is for the period 2008-2017[October]. • Salient features of the highway- • Design aspects and general observations -: 1. Crash Barriers Location- The crash barriers are to be provided on banks whose height difference is greater than 3.0m. There shouldn’t be space between metallic crash barrier and rigid concrete crash barrier. 2. Road marking- Road markings are to be properly laid on the carriage way for controlling, warning, guiding and informing the road users. 3. Median and islands - The median and islands are to be raised at least to a height of 300mm by using kerb stones and the gap has to be filled by the locally available material for the plantation along the median. 4. Service roads- Service Roads has to be developed in the areas which have high urban area such that local traffic can be separated from highway traffic. 5. Truck lay bay and Bus bay- Informatory sign boards should be kept in front of truck lay and bus bay. Proper lane marking need to be carried out. Raised pedestrian footpath has to be constructed for safety of passengers. • ConclusionBased on this case study on the four-lane national highway-65 [previously NH-9] the following conclusions have been drawn: 1. It is found that road markings, condition of shoulder, condition of carriageway and median opening are the factors for causing accidents on the NH65. 2. It also observed that the moderately moving vehicular traffic is generating traffic problems for the fast moving vehicular traffic as it generally occupies innermost lane of national highway. 3. Along this four lane national highway, service roads need to be provided so as to isolate slow moving vehicular traffic from fast moving vehicular traffic. 4. All the unauthorized gap-in-median should be closed and necessary provisions like foot-over bridges to be provided for the local neighborhood to cross the national highway on the priority basis. REPORT NO. 3 ROAD SAFETY AUDIT ON URBAN ROADS OF BENGALURU BEERANNA , PRAMODH A [ GOVT. SKSJTI, BENGALURU, KARNATAKA] OBJECTIVES o Identify the blackspots for which RSA has to be done using checklist as per IRC-SP:88-2010. o Inventory of road geometrics and traffic condition. o Collect accident data from FIR copies provided by traffic police stations in the city for past 3 years (2017-2019) that helps in statistical accident analysis. SITE LOCATION – From Madiwala to Kempegowda International Airport, Bengaluru, Karnataka.[Dec.2020] PROJECT METHODOLOGY o From the statistical analysis of collected data, blackspots that connects NH around the city are selected. o Odometer survey is done to check length and confirm chainage of respective stretches of roads. o Examine the existing features and conditions of roads in the selected blackspots at day and night using IRCSP:88-2010 (Road Safety Audit manual) checklist. o Carryout questionnaire survey - road users ,traffic police officers opinion might be helpful for analysis. o Suggest required measures that needs to be done at the respective blackspots to reduce the number of accidents. CONCLUSIONS o Most of the black spots are present near NAMMA METRO- Bengaluru construction sites, because of which road geometry is altered form its original features turning them as blackspots. o These black spots connects to NH so the vehicle speed is more along with increasing vehicle density and median openings is the cause for most of the cases resulted in accidents. o Intelligent Transport System has to be implemented in Bengaluru city for efficient management of traffic. o Awareness and accountability has to improve among the road users because most of the accidents were occurred due to negligence of driver, traffic violations by road users. HILL AREA ROAD SAFETY AUDIT CASE STUDY ON NH-34 UTTARAKHAND (INDIA) REPORT NO. 4 ANOOP KUMAR , DR. A.K. MISHRA [M.M.M.
