is pretty damn clear. Ripple bars to wake cyclists up to the crossing - zebra crossing for pedestrians. I'd be stopping if a pedestrian was walking towards it.
Now we just need good strategies to ensure pedestrians don't walk along the path, as that is illegal.
The pedestrian crossing is part of the strategy to move pedestrians off the bike path. The crossings are located at traffic lights where pedestrians will cross the road; the zebra crossing is a big hint that the pedestrian should keep walking across
the bike path rather than turning immediately to walk between the nice trees.
Now we just need good strategies to encourage cyclists to ride along the path or the road, not weaving through the pedestrians.
