It seems the question in this thread is “Where does a Motorway end and a Trunk begin” where there is a stretch containing at-grade intersections between two segments that could otherwise qualify as motorway. In my neck of the woods, we have Watkins Drive, where by a consent decree, there are intersections and traffic lights. There is a clear demarcation between Motorway and Trunk - the speed limit drops to 45 MPH before the non-Motorway stretch, then goes back to 55 MPH when controlled access continues. Therefore, I would transition from motorway to trunk at the speed limit transition Then I also have K-7 between Olathe and Bonner Springs, where KDOT has incrementally upgraded the road. From Olathe heading north, there are four interchanges (119th, College, K-10, Prairie Star Parkway) an driveway intersection, an interchange at 83rd, an intersection at 75th, interchanges for Shawnee Mission Parkway and Johnson Drive, intersectons at 47th and 43rd, and Interchanges at K-32 and Nettleton. I would mark off as Motorway from the PSP interchange south and from 43rd north to Nettleton, and in the middle section including the Johnson and SMP interchanges. As 83rd is a single interchange between two intersections, it would not be given a Motorway designation. First, I would look for any field-verifiable transition (e.g. pavement or speed limit changesj between an interchange and intersection. If there isn’t one, I’d be inclined to either make the transition at the start of a turn lane or at the end of an acceleration lane. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
