What HCM says?
Source: HCM 2000, Chapter 18.Slide3
Pedestrians have to cross more than one stage and wait for a WALK in each stage.
But, what if…
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.

‘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
