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 activity reduction in a pedestrian-to-vehicle communication network comprising steps of:
-
a) monitoring over a predetermined time period a distance between a particular pedestrian who carries a respective pedestrian communication unit (PU) and a vehicle closest to the particular pedestrian to determine a distance deviation; and b) if the distance deviation is lower than a predetermined threshold, reducing transmission activity by the respective PU. - View Dependent Claims (15, 16)

17. A method for activity reduction in a pedestrian-to-vehicle communication network comprising steps of:
-
a) identifying pedestrians at a given level of risk from accidents with vehicles, each pedestrian having a respective pedestrian communication unit (PU) associated therewith; b) transmitting an activity control message which includes information related to the given level of risk relevant to a particular pedestrian; and c) adjusting the communication activity of a respective PU associated with the particular pedestrian based on the information received in the activity control message. - View Dependent Claims (18)
