So far so good ... pedestrian faced with push button unit to activate signals facing pedestrian and, at right angles, the motorist.
This set up is mirrored from the opposite side, so that pedestrians from either side are faced with only one push button unit for two potential crossings on to a central island. The increased danger comes from the fact that the stop lines for traffic (on either side) are at the crossings not directly adjacent to the ones carrying the units (unless you are at the island).
Such a set-up is confusing for both the pedestrian and the motorist, neither of whom can make eye-contact. The pedestrian needs to be able to tell that the motorist has stopped for him. The motorist needs to be able to tell that nobody is still crossing during the amber flashing phase (yet for sure, there will likely be nobody at the crossing nearest to his stop line).
I have observed both pedestrians and motorists confused by this layout. Unfortunately, there has been a road death here, which is still marked.
