1. A method for monitoring headway to an object, the method performable in a computerized system including a camera mounted in a moving vehicle, wherein a processor acquires in real time a plurality of image frames including respectively a plurality of images of the object within a field of view of the camera, the method comprising the steps of: tracking over time thereby detecting in at least two image frames at least one edge in the respective images of the object; based on said detecting, computing a smoothed dimension of the object by smoothing in time a measurement of said at least one edge over the respective images of the object; and calculating range to the object in real time by comparing an instantaneous measured dimension of the object to said smoothed measurement of the object.
