ROAD ACCIDENT ANALYSIS FOR DEHRADUN CITY WITHIN GIS ENVIRONMENT

Abstract

In India, various problems related to road network can be identified as inadequate capacity, congested city roads, safety, lack of wayside amenities, poor riding quality etc. The growth in size, volume, and speed of the automobile industry has led to serious accident hazards on the roads. Therefore traffic management is basically optimizing the use of the existing street system and improves road safety, without impairing environmental quality. GIS applications in transportation engineering, which led to new algorithms for shorted path analysis, routing procedure, solving the transportation problem like identify accidents patterns, risk assessment, site selections, and urban transport managements. GIS packages, provides the technology to solve the transportation integration problem with capability of linking graphic entities to the many attribute databases. This thesis highlights the accident scenario in Dehradun City and creates a database within GIS environment for analyzing the accident data. The data has been classified into four categories namely Fatal accidents, Grievous accidents, Minor accidents and Non-Injury. A database for the accident data has been created according to year-wise in ARC-GIS 8.1, which gives all details related to accident data like type of accident, location, type of vehicle, date etc. Analysis of accident data has been analysed in ARC-GIS 8.1 with respect to Time, Year, Month, Road and type of accident so that a clear picture of the accidents in Dehradun is obtained. The accident-prone locations have been identified with the help of Accident Rate (AR) Method and Accident Severity Index (ASI) Method.
