1. A multiple-object speed tracking apparatus comprising: a camera configured to capture a set of images of a monitored area, wherein a longitudinal axis of the camera may be positioned at any viewing angle in relation to a longitudinal axis of a roadway as long the viewing angle allows images of at least two moving objects moving simultaneously within the monitored area to be included in one of either a set of low resolution images or a set of high resolution images; a computer system configured to analyze the set of images to detect the at least two moving objects and substantially simultaneously determine a calculated rate of speed of at least one of the two moving objects, wherein the computer system provides an on-site speed calibration process configured to transform locations in an image from the set of images into real-world coordinates by considering, in a single step, both perspective and scale of the image; and an apparatus mount upon which at least one of either the camera or the computer system is positioned, wherein the apparatus mount is one of either a fixed mount or a mobile mount.
