Abstract
The present invention is an infrared traffic sensor with feature curve generation to derive empirical information for determining traffic patterns. A real-time IR image camera is positioned over an automobile and truck traffic thoroughfare for collecting video image data of the traffic thoroughfare. Data in the form of a video signal taken by the infrared video camera is received by a signal processing unit for processing the data. The processed data is used to generate statistical feature curves from which the empirical traffic information such as the number of vehicles, the speed of the vehicles, and the classification of the vehicles are determined.
