The VMS is one of the most effective tools in the field of intelligent transport systems, which in addition to the graphical representation of the traffic situation, can provide an appropriate notification platform for essential messages to users. For this purpose, in this paper, introducing the effective parameters in selecting the optimal placement of news message boards with the aim of maximizing the efficiency of this equipment in the distribution of traffic in urban roads, ARCGIS software has been used for this purpose. In this regard, by simulating the city-wide interurban network of Karaj in the software and defining the parameters involved in location selection, it is suggested that the locations are located, while in the optimal visual position, considering the volume of traffic, the decision-making power of users in choosing Other paths are provided after crossing the board.
