No thru traffic #73

Open mattwigway opened 8 years ago

mattwigway commented 8 years ago

We need this to prevent the router from taking shortcuts through park and rides, and more generally as well.

abyrd commented 8 years ago

Just decided in discussion: we won't have no-thru-traffic per mode, just a single flag. Because in practice no-thru rules don't apply to bikes and pedestrians, and sometimes they even exist specifically to make it pleasant for bikes and pedestrians.

So no-thru flags will be used only for actual no-thru-cars situations, and we will avoid shortcuts through parking lot link edges and such by explicitly checking and forbidding traversal of two link edges in a row.

@abyrd do you recall if this was implemented?

buma commented 6 years ago

It seems it wasn't. We still have 3 flags. And no thru traffic is just set. Flag isn't read anywhere.
