Hello, what is the purpose of these new nodes you propose? What is your reason for violating the first normal-form of database-design? How do you suppose to generate them? If you want to have a simplified data-set for your and other's routing-applications, you are free to render it regularly and provide access to it for everyone who may find it usefull. They should not, however be a part of OSM. | <rtnode id="757312" lat="51.3450785" lon="-0.4606170" | timestamp="2006-04-17T08:57:53Z"> | <rtnode ref="251490798" distance="2km" traveltime="10minutes" | maxspeed="60kmh" /> We already have maxspeed and similar in the ways. Travel-Times depend heavily on the type of vehicle you are using and external factors and need to by calculated by the routing-application. Also the selection of osm-ways that are relevant for routing depends on your vehicle. Bicycles and motor- scooters cannot use motorways. Heavy trucks cannot use certain bridges...
