Abstract (en)
[origin: US6489920B1] From a body located at a distance above the surface of the earth, an image is recorded of a region that is located underneath the body on or above the surface of the earth and that has a diameter of at least one kilometer. The recorded image is fully geocoded and comprises a grid dimension small enough that vehicle densities located in the region can be recognized. The recorded image is evaluated with respect to these vehicle densities and the spatial allocation thereof to the associated roadways. The method is used for acquisition of the state of street traffic over a large area.
