A positioning system (10) includes a forward-viewing camera (20), a ranging-sensor (28), and one or more controller-circuits (34). The forward-viewing camera (20) detects lane-markings (22) on a roadway (18) ahead of a host-vehicle (12) traveling in a travel-lane (24). The ranging-sensor (28) detects a position (30) of an other-vehicle (16) traveling on the roadway (18) behind the host-vehicle (12). The one or more controller-circuits (34) are in communication with the forward-viewing camera (20) and the ranging-sensor (28). The one or more controller-circuits (34) determine lane-widths (38) characterized by pairs of opposed control-points (42) at a first-distance (40) ahead of the host-vehicle (12), track relative-positions (44) of the control-points (42) while the host-vehicle (12) is traveling along the roadway (18), determine a rear-side road-model (14) based on a temporal-history (46) of the relative-positions (44) of the control-points (42), determine a lateral-offset (54) of the other-vehicle (16) based on the rear-side road-model (14), and operate the host-vehicle (12) in accordance with the lateral-offset (54).
