Wayfinding sign
Portland's bike-route wayfinding signs give destinations, distances and travel times. The text is often too small to read from where bicyclists must decide which way to turn. For good legibility, either a much larger sign would be necessary, or else a simpler one giving a route number, and used in connection with a map.
