SatTrafikk

Vehicle detection in satellite images

The SatTrafikk project is a cooperation between NR and the Norwegian Public Roads Administration (Statens Vegvesen, Vegdirektoratet) where the aim is to develop methods for road traffic statistics by satellite remote sensing. Using high resolution satellite images we are trying to teach the computer how to count the number of vehicles on given roads. The authorities use traffic statstics information when they are planning construction and maintenance of the road network. As seen from 450 kilometres above the surface of the earth, the vehicles are pretty small. Tree shadows and road markings often disturb the view, and make this task a challenging one - especially since Norway is full of curvy, narrow roads!

The image shows the pan-chromatic band of a Quickbird satellite image of a (subset of a) typical scene.
