Methods for lowering the power consumption of a battery-operated pedestrian V2X device, comprising: determining a location of the pedestrian relative to a road using a physical map, determining whether a movement of the pedestrian is consistent using a heatmap, and based on the location of the pedestrian relative to the road and on the consistency of the pedestrian movement, powering down a V2X functionality inside the pedestrian V2X device by setting a V2X receiver operation cycle, a V2X transmitter activation state and a Global Navigation Satellite System (GNSS) sampling rate, thereby enabling low power operation of the pedestrian V2X device.
