 Pedestrians have to cross more than one stage and wait for a WALK in each stage.  Diagonal crossing.  Which way? A-B-C or A-D-C ?  Bikes making two-stage (pedestrian-style) left turns are sometimes allowed to follow one direction only.  There is more than one WALK interval per signal cycle. Crossing Boylston Charlesgate West, Boston

‘Diagonal Crossing’ accounts for the situation where pedestrians or bikes need to cross the intersection diagonally, and therefore make a two-stage crossing, with path choice. ‘Multi-stage Crossing’ accounts for the crossing where pedestrians or bikes have to cross many stages and wait for WALK interval during each stage.
