What are we? Chopped liver?

A plea for signage for pedestrians not just drivers.

In walking around New Rochelle I have become increasingly aware of street signage and it's perpetual focus on drivers over pedestrians.  Traffic signs do not tell a universal truth, they tell a truth that applies to drivers. Dead End, No Outlet signs are often placed where there is a way through for pedestrians.  Sometimes it is so obvious that it doesn't matter like the Dead End sign below - note the sidewalk that runs all the way to the car park....

....but in some locations the signs can be misleading.  The two below came one after the other and gave no indication of what a pedestrian could expect further along the road.  The 'No Outlet' does not rule out an "In Let' but I have found the use of 'Dead End" and 'No Outlet' to be inconsistent so some additional information would be helpful.

Ignoring the 'Do Not Enter' and the 'No Outlet' brought me out to a main road along a fully paved piece of sidewalk. Would it be too much to ask that we have some pedestrian access signs in the places that it is not obvious? 
And speaking of obvious, why are there so many 'Dead End' signs in places so obvious they can only be considered redundant?

Wayfinding, as distinct from traffic signs, are happily often designed for pedestrians and can include not just directional help but distance in feet, time or number of steps.  I'm looking forward to New Rochelle making strides (sorry couldn't resist) on improving its Wayfinding and while these signs are often put in place for visitors I maintain that locals need them too.  Particularly, as said earlier, if we want to encourage people to get out of their cars and walk then it is important that they know how to get around easily and where there are shortcuts.  Pedestrians have a great advantage over drivers when it comes to cut throughs including through buildings, alleyways, walkways, and informal cut throughs where pedestrians have created their own unofficial walkways aka desire lines. 

And finally, a plea for clear signage.  Here's an excerpt from Artists Walking Home in Vancouver that shows how planner enthusiasm can lead to confusion.
