Neat, there seam to be a lot of good routing method appearing for OSM. All with interesting differences over what the commersial sources produce, (eg Google, Multimap, etc) Not usually wrong but different, Does anyone know of any Routing code thats Open Source. Is there any way to encourage the system to use Dual Carriage Way Primary Roads over Single Carriage Way Primary Roads (or in this case Seconday) eg eg A289 vs B2108 is Strood, Kent. Also people seam to have used Trunk and Primary interchangeable. what is meant to be the difference. Peter.
