Determination the best locations for installing ITS equipment to reduce accidents (case study: Polezal Roadway, Andimeshk, Iran)

The use of intelligent transportation systems (ITS) has been very effective in traffic safety. In recent years, using ITS systems has received attention in Iran to increase traffic safety and reduce road accidents. However, finding of optimum and suitable locations for installing ITS equipment is very important and essential. Using the Geographic Information Systems (GIS) and location data analysis are a reasonable method that can be used to determine the ITS equipment locations. In this study, the history of accidents occurred along a specific road between 2006 and 2009 were collected and analyzed. After analyzing the causes of accidents, location and type of accidents, the best places to install the equipment is proposed. Andimeshk-Polezal road with 60 km length which is important Asian Highway in Iran is selected as a case study. Analysis of road accidents in Andimesk-Polezal road shows that human factors constitute nearly 97% of all the factors. With considering the impact of ITS in reducing human factors (by warning and notification of road users) that the use of ITS in the appropriate locations along with the highway police control will dramatically reduce the number of accidents in Andimeshk-Polezal roadway.
