c technology is in place as a platform, subsequent applications can be developed. Cooperative ITS can greatly increase the quality and reliability of information available about vehicles, their location and the driving environment. In the future, cars will know the location of road works and the switching phases of traffic lights ahead, and they will be able to react accord- ingly. This will make travel safer and more convenient. On-board driver assistance, cou- pled with two-way communication between vehicles and between cars and road infrastructure, can help drivers to better control their vehicle and hence have positive effects in terms of safety and traffic efficiency. RSUs play an important role in this RSU is a communication/computing device located on the roadside that provides connectivity support to passing vehicles. Ixxiv Introduction and Background technology. Vehicles can also function as sensors reporting weather and road conditions including incidents. In this case, cars can be used as information sources for high- quality information services. RSUs are connected to the traffic control center (TCC) for management and control purposes. The traffic light information and the traffic informa- tion obtained from the TCC can be broadcast via the RSUs to the vehicles and the RSUs can further collect vehicle probe data for the TCC. For reliable distribution of data, low-latency and high-capacity connections between RSUs and the TCC are required. This type of application is made possible by setting stringent end-to-end latency requirements for the communication service between RSU and TCC since relayed data needs to be processed in the TCC and the results need to be forwarded to the neighboring RSUs. It must be noted that the availability of the communication ser- vice has to be very high in order to compete with existing wired technology and in order to justify the costly deployment and maintenance of RSUs.
