OpenStreetMap

i discovered again routing errors on Espana this morning when i peeked to my garmin's suggested route while waiting for the traffic signal to turn green. The turn restrictions i put at the corners of trabajo and vg cruz are now working but found out there should be another one at the corner of P Noval. found also missing links for morayta plus the crossings for sh loyola. been some time since i passed by cm recto and espana but the road crossings are there for the jeepneys pass by the place.

Nicanor reyes (morayta) should also have a center island, will correct it later.

from araneta avenue, it seems garmin routing algorithm likes straight roads (where road class takes predecedence over distance according to my observation) but two microscopic bends (i discovered after zooming in to reveal the error) made we want to turn right to victory avenue then kitanlad)...routing's ok now basically going to makati via my route and every recalculation is accurate. there's only a minor glitch again at the corner of JP rizal and makati avenue. i noticed a short center island not present on OSM...will also correct later.

I expect all my routing woes to be over next week.

then i'll focus on POIs :P

Do you know about Keep Right?
It will help you find some errors ( like roads not connected) on the map.

It is good that you have been focusing on road routability. I don't have particular interest on this issue because it doesn't affect me on my usual bike commute :). Keep it up!

maning, the former routing engineer in me came alive with OSM :P want to perfect routing so the next time wifey goes astray, she can rely on OSM to save her day...
so far, QC and Makati's doing well, will again check Manila.
