ABSTRACT

An accident is an unforeseen incident that can have inconvenient or undesirable repercussions while also being insignificant. In order to discover the accident black spots, the severity of accidents requires to find out accident severity values. The Weighted Severity Index method (formula) was used. To know the accident locations, secondary data was collected from the Rachakonda Police Commissionerate, which included three years (2016 to 2018) of accident data, as well as primary data collected in the study area to determine traffic volume and speed values of vehicles. Secondary data collected were analyzed using MS Excel software in the form of Day, Month, Year, Time, and Location of accidents, as well as Fatal, Major Injuries, and Minor Injuries. Furthermore, the days that saw the most collisions, the months with the most accidents, the times that saw the most accidents, the years that saw the most accidents, the locations that saw the most accidents, and the types of injuries that were documented have all been identified, further determining the number of accidents that happened on each route section. The months with the most and least accidents were recorded, along with the days and times when the most and least accidents occurred. Using this analyzed data, accident locations were plotted on a map, and the kilometer-wise number of accidents found in the study region was calculated using the map. To assess the severity of the accidents, specific weightages were applied based on the categories of accidents. Using these severity ratings, black spot stretches are discovered and ranked from high to low; this information is particularly beneficial to road users when traveling in the black spot stretches to avoid accidents.
