GIS Based Site Selection of Traffic Sensor Based on MCDM Methods (TOPSIS, PROMETHEE and VIKOR)

Smart traffic monitoring is a new method of traffic data acquisition. Traffic sensors are the core of such system in consequence optimum allocation of them increases efficiency of monitoring and decrease cost of installation. Although multi criteria decision making (MDCM) idea is a common method for this purpose, the big challenges is selection of the best MCDM method. Thus this paper tries to discuss advantages and disadvantages of different MCDM methods to determine proper mythology for optimum allocation of traffic sensors. To do the analysis a pilot junction in north of Washington was selected. In next step multi criteria decision making concepts were studied to compare urban links rank a long selected junction, respecting final calculated weight based on AHP method .To do this step some multi criteria decision making method such as PROMETHEE and TOPSIS and VIKOR were compared for determination of optimum link for traffic sensor site selection.
