Identification of “Black Spots” without Using Accident Information
Abstract
In the present research, identification of so-called black spots with no use of accident information is investigated along “Iraanshahr-Sarbaaz-Chabahr” road in Baluchistan, Iran. First, by an overview on the road, all factors that could potentially contribute into accidents along the road were determined. Next, the road was divided into 8 sections based on uniformity and homogeneity of each section in terms of geometry and regional conditions. At each section, potential black spots were identified and questionnaires were prepared to collect opinions from 30 experts who were well-familiar with the road. The collected data was analyzed using SPSS Software, leading to the identification of black spots. Finally, the identified black spots were compared against those obtained by traffic police based on accident information.
