Development of A WebGIS Supported Road Traffic Accident Data Management System: A Case Study Of Nairobi County

Abstract

his research project work seeks to improve road traffic data storage and accessibility through the use of WebGIS by creating a road traffic accident data management system. A case study method was employed with Nairobi County as the study area. An Accident Management System was developed encompassing a database managed by PostgreSQL and a webserver. It has the advantages of having centralized data, readily accessible as opposed to the current status where data access is constricted by office working hours and manual data requisitions that take time to respond to. Simple statistical analyses are afforded by this system for data comparisons, estimations and inferences. The location of accidents usually given in textual formats has been addressed hence viewing of accident locations on maps is possible.
