This paper aims to assess the possibility to implement low power, short distance standard communications technologies and cheaper technology for dedicated applications, such as data dynamic data collection, data distribution, or messaging, for better information of vehicles (and, in general, traffic participants). The main concern was to determine the already existing communications that are most probable to be found in the field. As Wi-Fi is the most used communication inside the buildings, but is also likely to be found in vehicles (for communication between their equipment of just used by mobile devices inside of them) the authors have considered that this should be the first step in determining characteristics of the wireless communication environment near the road network. Therefore, specific measurements regarding communications interferences and Wi-Fi channel density have been performed in some representative road junctions in Bucharest and along the most crowded public transport routes (buses and trams), with the results being useful in choosing proper ways for employing new communications with little chance of interferences.
