I use role=forward typically on oneway streets where bicycles are not allowed against the direction of the motorised traffic and where the opposite direction bicyle traffic on the bicycle route is using neighbouring streets for the bicycle route in the opposite direction of the route relation, but as long as the bicycle flow is in the direction of the oneway I use role forward. The only case where I would use role=backward (in a bicycle route) is when there is a contra-flow cycle lane tagged on a one-way street. Similarly when a bicycle route include roundabouts (in that case I split the roundabout and use two "role=forward" segments to carry the bicycle route.along the roundabout. I admit that I learned this approach from other mappers, but I am not sure it's documented in the wiki, now that I am thinking about it. Volker
