Status: - Website: heavily in development - Routing engine: don't know (not maintained by me) Goal: Use OpenStreetMap data to make a routing website utilizing as much other (opensource) services/application as possible. I develop *only* the glue logic; the webinterface. I'm always interested in bug reports, suggestions or code snippets but I don't maintain the routing engine. Regarding your route from Montreal - New Haven, works for me. fastest: <http://www.yournavigation.org/?flat=41.308153&flon=-72.928158&tlat=45.531875&tlon=-73.636881&v=motorcar&fast=1&layer=mapnik> Shortest: <http://www.yournavigation.org/?flat=41.308153&flon=-72.928158&tlat=45.531875&tlon=-73.636881&v=motorcar&fast=0&layer=mapnik> If a route stops somewhere between the start and stop coordinates then the routing engine (Gosmore) wasn't able to calculate a complete route and returns it's best solution (which might be using a lot of small roads even when you chose 'fastest'). In case of Montreal - Buenos Aires this is caused there isn't a continuing connecting road between those cities. Especially in Central America there is a lot of 'here be dragons' land. This effectively prevents routing between North and South America. Although I've put some working long distance examples below there are also situations where Gosmore just seems to 'give up' while a route is possible. Example: just try to route from Berlin to Madrid (type those names to get the coordinates). Gosmore is not able to return a complete route but routes from Madrid to Amsterdam and from Amsterdam to Berlin (or Madrid - Geneve - Berlin and many other in-betweens) are working just fine. Some other examples: Glasgow - London <http://www.yournavigation.org/?flat=55.79274&flon=-4.354897&tlat=51.389725&tlon=-0.114174&v=motorcar&fast=1&layer=mapnik> GB: Northeastern tip - Southwestern tip, 1445km <http://www.yournavigation.org/?flat=58.642109&flon=-3.068728&tlat=50.066191&tlon=-5.700649&v=motorcar&fast=1&layer=mapnik> Europe: Amsterdam - Madrid, 2056km <http://www.yournavigation.org/?flat=52.36227&flon=4.798082&tlat=40.409275&tlon=-3.710699&v=motorcar&fast=1&layer=mapnik> There are also other routing 'problems' (weird route decisions) which are difficult to explain, so I'll create a wiki page for that where they can be gathered which might help to solve common problems. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
