Methods and apparatus for communicating safety message information

摘要

Various embodiments, relate to a communications system in which communications devices of users and communications devices of vehicular systems communicate safety messages through a cellular communications band or the DSRC (Dedicated short-range communications) vehicular communications band or a combination of both. Various methods and apparatus are directed to communicating safety messages between vehicles and pedestrians/cyclists through the use of a cell phone, thus improving the impact of vehicular communications. In some embodiments, at least some cell phones in a communications system includes both a DSRC communications capability and a cellular communications capability.
