Choosing the Suitable Position for Installing Surveillance Systems

The widespread use of intelligent transportation systems necessitates guidelines for choosing the best position for installing the intelligent transportation subsystems. Among the existing intelligent subsystems, surveillance systems are the most important. In this paper, a guid eline for choosing the best position for installing the surveillance systems in harmony with other intelligent subsystems on a specified road is introdnced. A survey hetween managers and technicians of Ministry of Roads and Transportation of Iran is conducted to determine the main goals of using surveillance systems and suitable measures of performance as well as their importance weights. A worksheet is, then, prepared which shows the important characteristics of surveillance systems and their weights. Level of surveillance for a specific road can be determined using the characteristics of that road. Three level of surveillance are defined. Also, there is a list of important points for each level of surveillance. The important points on the considered road being chosen, their exact position and characteristics of the camera must be determined. The proposed guideline is used for a rural road in Iran and its advantages have been shown.
