Abstract

A computer implemented method for generating traffic pathways that includes recording images from a transportation site with a fixed position camera. The method further includes extracting vehicle point data from the images, and calculating projected vehicle characteristics from the extracted point data to provide an extracted vehicle continuous data set. The method may further include generating a simulated traffic flow and simulated vehicle motion from the extracted vehicle continuous data set. A traffic pathway can be calculated using simulated vehicle motion and simulated traffic flow. The traffic pathway can be used for directing a guided vehicle on the transportation site.
