Use Case: Safety-related services are concerned with real-time safety messages, such as warning messages (e.g., abrupt brake warning message) to reduce the risk of car accidents. Note: Because of privacy concerns, it is possible that the raw data will only be accessible within the vehicle, and that the information between vehicles will be much higher level and may not have as stringent of requirements. However, this analysis is based on the assumption that raw data will be communicated between vehicles. Cooperative awareness: warning and increase of environmental awareness, ability to detect location, speed, and heading of surrounding vehicles. Cooperative ITS safety applications rely on a combination of data from in-vehicle sensors and data shared by surrounding vehicles over a wireless link Examples of Safety related services: ・Forward Collision Warning (FCW) ・Control Loss Warning (CLW) ・Emergency Stop ・Emergency Vehicle Warning ・Queue Warning ・Road Safety Services
