comment Database design: road topology in GIS
@Mapperz - Even in Canada, in Quebec, Right on Red is not allowed, and in some jurisdictions, they implement a 15 second all white rule (meaning, pedestrians on all approaches get white)

comment Provide 3 colors to a polygon
On top of the comments above. by different colors, do you mean a gradient or distinct colors based on some data. I'm assuming you have polygon_a with variables A, B, C. and you want to show them all.

Fabien, Thanks for the amazing info, I wasn't aware of the major differences between Arc and pgRouting. Currently, I haven't purchased a network analyst license, I'm considering using pgRouting/postgis for this application. any suggestions on how to mode3l and represent center lanes?
