Why does DirectRoute take me on a route that I do not think is the fastest or shortest?
DirectRoute calculates routes using the “shortest time” or “least cost” routing technique. The program looks at the start and end points. It looks at combinations of road segments between the two points, starting with an area around the start. It mostly considers the length of the possible road “paths” and the posted speed limit data that is stored with each road segment. (There are some additional factors.) It basically chooses the shortest total road path having the highest total speed limit. It doesn’t know about local traffic patterns, road closures, etc. So, you will usually be better than DirectRoute at finding an appropriate route in areas you know well – because you have more info. DirectRoute helps you find a viable route in areas you don’t know well.
