@Bumber breadman's proposal of one bit for "is directional" would work just fine because he's repurposing the existing two traffic designation bits. Currently each tile stores two bits of traffic information - just enough to store high, normal, low, or restricted. breadman's suggested new bit would override the normal meaning of the two existing bits and use them to store the intended direction of the path. Dwarves going in various directions across it would "see" different traffic restriction levels depending on the N, E, S, W value encoded where the traffic restriction level normally goes.
