Identifying Critical Road Segments Affecting Traffic Accidents With Geospatial Analysis in Kocaeli City

Abstract

Since urban road accidents in Kocaeli is a severe problem and it is anticipated that accidents can be interrelated to road infrastructure characteristics. This study aimed to explore risky road segments related to urban road accidents using GIS analysis and conduct field surveys on these areas to define their possibly poor geometric design parameters. The study revealed some possible accident prone locations using spatial density maps for the period of 2015 in Kocaeli city. A risky road segment (i.e. DSİ Junction) was found to have serious deficiencies in terms of driving safety due to the sharp reverse curb.
