this is a wrong route on fastest car mode. its still less hard to fix. http://yournavigation.org/?flat=28.440111&flon=77.03397&tlat=28.455312&tlon=77.045064&v=motorcar&fast=1&layer=mapnik This is totally wrong which i could not fix after many attempts. in this fastest route, it takes the second entry (sec 15) to the express way and not the first (rajiv chowk). express way is motorway (more points) than secondary. i even tried changing service lane to "service", "territary", "residential", etc but gosmore just does not like to take the fastest route. please suggest if there is a way to solve this problem. i understand that gosmore does not consider calming (speed brakers) and traffic signals yet but even then its the wrong route based on scoring road types. then there was once I routed to go to palwal (never gone there before so had no clue on how to go) and reached NH1. that NH1 was inside a sabza mandi and was only wide as 5 metres in a very congested locality (don't know where i was in delhi). gosmore was regard this road as trunk and so it should be too but it should be scored as living_street while routing for speed. there are many such examples i could try but i can't think of good solutions to these. most of my routes circle around cryptic areas like dhual kuan (and properly considering one ways) or airport junctions. such areas are very tasty to find flaws. There other nonsense routes like ( http://yournavigation.org/?flat=28.440111&flon=77.03397&tlat=28.499143&tlon=77.089974&v=motorcar&fast=1&layer=mapnik) which mostly happen for incorrect one way tags or minor error in connecting streets etc. 2009/9/3 Gora Mohanty <[email protected]> > On Wed, 2 Sep 2009 22:17:17 +0530 > ヴィカス ヤダワ (vikas yadav) <[email protected]> wrote: > > > Welcome pal! > > > > Im Vikas from south west gurgaon. > > I have been working along with gosmore and improving quality > > (beside regular surveys). > > But there seems to be a hard hurdle for general routing logic to > > apply on indian streets. > [...] > > Not sure where you feel that the hurdle is.
