That makes sense - I've learnt from other threads that some decisions in OsmAnd are about what will typically be found in OSM rather than what would ideally be there. But out of curiosity I did some rough calculations on the junction shown on the right in the original post (it's at 52.90854, 6.00013). If you could instantaneously accelerate from 100 to 130 while crossing the junction between the off- and on- ramps you'd save no more than 3 seconds compared to keeping on the highway. But I think there must be a give-way/yield indication at the junction because the ramps are *crossing* a slower road. This hasn't been added to OSM - if it had been, would that cause a routing penalty big enough to compensate for the 3 seconds? Maybe there is also a penalty for having to merge back onto the highway. -- You received this message because you are subscribed to the Google Groups "OsmAnd" group.
