Wireless Communications Vehicle-to-Vehicle and Vehicle-to-Infrastructure
Rapport, 2008

This state-of-the-art survey addresses wireless communication vehicle-to-vehicle and vehicle to-infrastructure. With infrastructure is here meant roadside equipment. Today, wireless links are used for e.g. collecting tolls, telephony, traffic congestion warnings (TCM), positioning (GPS). Wireless communication can also be used within safety, efficiency and infotainment areas. The purpose of this report is to make a survey of the available open project related information and summarize it. The considered projects were located in Europe, USA and Japan. Finally a total of 79 projects were considered significant. The approach for getting an overview of these projects was to combine project descriptions (i.e. project explicit views) with project classification metrics (i.e. project implicit views). It is believed that this approach results in a representative state-of-the-art overview of wireless communication vehicle-to-vehicle and vehicle-to-infrastructure projects. In this report links are also given to a number of related organisations (about a hundred). Apart from the projects as such it is possible to see differences in Europe, USA and Japan using the surveyed projects. There is a strong governmental support in USA and Japan. In Europe governmental support is indirect via the European Commission and the picture is more heterogeneous with many different countries involved. As it seems this is reflected in * The higher number of projects in Europe compared to USA and Japan. * More overlapping projects in Europe compared to USA and Japan. Several projects seem to address the same issues. In Europe, maybe the projects Coopers, Safespot and CVIS will become the central projects since all three are large projects with many important participants and addressing many application areas.
