note that OsmAnd doesn't do any time dependent routing, or at it least it<br>
didn't do it for a very long time.<br>

might work to some extent but I see it as important deficit that the directionality <br>
of the road isn't modelled.. sooner or later it will cause disaster. Imagine routers <br>
to issue commands like "turn around and follow the road in opposite direction" when the<br>
diver missed an exit for example.<br>
Also, just one single entry point that someone has forgotten to tag with a barrier<br>
or has the wrong time information and the router will send kamikaze drivers in the wrong <br>
direction into the expressway.<br>
<br>
My thought would be to have a variable time dependent number of lanes in each<br>
direction.<br>
<br>
Or "oneway" with conditional restrictions <br>
