Abstract
Methods for pedestrian unit (PU) communication activity reduction in pedestrian-to-vehicle communication networks include obtaining safety risk information for a pedestrian at risk for involvement in an accident and using the risk information to adjust a PU communication activity. In some embodiments, the activity reduction is achieved without implementing understanding of surroundings. In other embodiments, the activity reduction is based on risk assessment provided by vehicles. In some embodiments, the activity reduction includes PU transmission reduction. In some embodiments the transmission activity reduction may be followed by reception activity reduction for overall power consumption reduction.

14. A method for communication activity reduction in a pedestrian-to-vehicle communication network (PVCN) comprising steps of:
-
a) determining whether a particular person is located inside a vehicle by obtaining a pedestrian speed based on global positioning system (GPS) data, by establishing, that the pedestrian speed is higher than a predetermined speed value, and by detecting a vehicle closest to the particular person and monitoring a distance deviation between the particular person and the closest vehicle over a predetermined time period; and b) if the particular person is determined to be located inside a vehicle, disabling personal communication unit (PU) associated with the particular person, thereby reducing communication activity in the PVCN. - View Dependent Claims (15, 16, 17)
