dead-end streets have trails at their ends (or somewhere before the end)
that give pedestrians a route unavailable for vehicular traffic.
These routes usually offer safer routes than the busy streets the pedestrian
gets to bypass by taking them
A simple sign might be installed that calls attention to these safety routes. Such as...
Pedestrian routes in green are on public rights of way.
Solid colored lines indicate hard surface; dotted lines indicate dirt or gravel.
Pedestrian routes in gold are likely private (many are school children's "demand paths").
A few less-traveled routes are shown that are not outlined in color: consider these routes for emergencies.
