PBOT R3992 Obsolete Road Sign T-Shirt: Design Overview
This design recreates the now-obsolete PBOT Road Sign R3992 and its variants, a piece of Portland, Oregon's transportation history. The artwork focuses solely on the visual elements of the regulatory sign, as specified by the Portland Bureau of Transportation (PBOT).
Symbolism and Meaning
The core of the design is a symbolic representation of the original sign's purpose: to alert drivers to yield to cyclists. The artwork features a simple, yet impactful, black and white design within a rectangular format.
The sign’s primary visual element is a graphic of a bicycle lane, crossed by a diagonal arrow. This symbolizes the intersection of the vehicular traffic path with the dedicated bike lane. The presence of the arrow visually communicates the driver's obligation: to yield to any bicyclists present when entering or crossing the bike lane.
The black and white color scheme mirrors the original sign's specifications, per PBOT’s guidelines. The design's intent is to instantly convey the need to yield to cyclists when drivers cross or enter a bike lane, making it universally recognizable.
