Abstract: A map matching method (300) for a vehicle safety warning system (12) is provided. The method (300) includes the steps of a) determining (100) if intelligent transportation system (ITS) map data (18) is available, b) determining (112) a vehicle location (30) and a vehicle heading (32), c) determining (108) an envelope area (38) around a road feature (34) defined by the ITS map data (18), d) determining (110) a segment heading (46) for a segment (36) of the road feature (34), e) determining (120) a separation distance (50) between the vehicle location (30) and the segment (36) if (114, 116, 118) the vehicle location (30) is located within the envelope area (38), the segment heading (46) is substantially similar to the vehicle heading (32), and optionally, the segment elevation is substantially similar to the vehicle elevation, and f) map matching (128) the vehicle location (30) to the segment (36) if (126) the separation distance (50) is less than a threshold.
