RSUs placement using overlap based greedy method for urban and rural roads

The deployment of efficient roadside networks is a necessity for ITS deployment. The main challenge for the roadside deployment is to find a satisfying or best distribution of RSUs on the roads network according to the given conditions in order to meet the requested requirements of the roads operator. Additionally, various factors affect this process such as traffic, infrastructure and topological characteristics of the roads. This paper introduces an Overlap based Greedy Method (OGM) as a basis for RSUs placement and can be applied on urban and rural roads. This method in its current development mainly considers the RSU coverage radius and the overlap rate into the RSUs distribution process. Moreover, a wide range of influencing factors is considered through the prioritization of Sites of Interest (SoIs). The OGM method is developed within the recently started PRONET project and is integrated into its software platform. The tests conducted on selected roads environment in the city of Rostock (Germany) ensure: (1) decrease in number of chosen SoIs for placement compared to the original scanned number of SoIs, and (2) full (continuous) coverage cannot be guaranteed for a roads network using only the available junctions.
