Micro-mapping is only appropriate where there IS a separately marked pedestrian
area on the ground. SOME cycleways do have 'no pedestrian' markings, just as
some footpaths have 'no cycles' but the main discussion should be providing a
macro level view of the 'data'. On the whole, a simple single way may well
define the route for cars, bikes, and people. What needs to be clear is where
these routes separate into sections that are specific to each target.
Micro-mapping the physical areas on the ground is the ultimate, but showing
separate pedestrian and cycle crossing points, and linking them to foot and bike
only routes is something of a mess currently?
