Please consider my previous comment on the bus platform as mapping this way causes a duplicated highway edge as seen here:- https://tools.geofabrik.de/osmi/?view=routing&lon=-3.31107&lat=57.65009&zoom=18&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

The correct way is an unjoined platform area with a service road running through it.
