Investigation of Services and Application Scenarios for Inter-Vehicle Communication

In recent years, the number of vehicles has increased dramatically in Europe, USA and Japan. This causes a high traffic density and makes new security features a crucial point in order to keep the traffic safe. Inter-vehicle communication offers solutions in this field, as cars can communicate with each other. To this date, there is no special technology standardized for inter-vehicle communication. This is the reason why car makers, researchers and academics have invested money and time in different research projects so that in future they may come up with a common solution. Some of the technologies like DSRC, CALM, IEEE 802.11 or Infrared are thought to be more reliable than others according to different authors [9][23]. The technologies described above will help to improve road safety and application scenarios like lane change, blind merge or pre and post crash situations can be addressed. The position of each car is known through a GPS; speed, heading and other dynamic data of a car are known to all cars in the same vicinity. In this thesis, a thorough investigation of services and applications related to inter-vehicular communication technology (i.e. car-to-car and car-to-infrastructure or vice versa) will be carry out. The emphasis will be on requirements on the communication system, sensors and user interface in order to make the technology more useful for future vehicle alert system and to avoid as many of the mentioned scenarios as possible. A rear-end collision can be avoided if the driver is warned within 0 to 5 second of potential accident
