I think this is going too far into depth for any real navigation purpose, I'd say skip it as the restriction lasts for only seconds at a time, and in most cases, with no fixed timeline. Or if it is on a fixed cycle (such as downtown Portland's 29-second red lights forming a 58-second cycle, which allows most road users to go in the direction of travel at 15 MPH to hit every green, or pedestrians to walk against the flow to hit every walk light), the restriction is short enough to render it neglegable. There's also a slippery-slope angle to this...if we start trying to tag for "on red" restrictions, this becomes stupidly difficult to tag for. Québec (and I believe many other, mostly francophone, regions) for example, prohibits all turns on red in any direction at all intersections. Oregon and presumably a few other states allow turns after stop on red arrows by default, and permit both left and right turn after stop on red when the destination way is 1) the next way entering the intersection immediately left or right, and 2) if it's a left, the destination street is one way. In another words, you can turn left on red or red arrow from a two-way street into a freeway onramp or other one-way side-street (in practice, outside urban centers, we get too many transplants who don't know how to drive in Oregon, who try to apply the rules of the road from wherever backwards place they learned to drive, blocking traffic through legal movement opportunities until the signal literally cannot get any greener, finally pushing normally patient Oregonians to lay down the horn...we really need to treat out of state drivers getting licensed in Oregon as totally new drivers subject to graduated licensing, since it's clear other states are far more lax than we are in terms of licensing standards). _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
