Using OsmSharp: Calculate a vehicle's range
Along each point in the route the range of the vehicle is recalculated and the points that can be reached are shown using the little black points. A convex hull alorithm is used to display the area polygons. This can be updated to show a more realistic area.
Update: The demo project generating these images/movie can be found here:
