Safety effects of unsignalized superstreets in North Carolina.

Arterials across the United States are experiencing far too many collisions. Agencies tasked with improving these arterials have few available effective solutions. Superstreets, called restricted crossing u-turns by the Federal Highway Administration (FHWA), are part of a menu of unconventional arterial intersection designs that may provide a promising solution.

Nonvisual Cues for Aligning to Cross Streets.

Accurately aligning to the crosswalk is an important component of safe street crossing for pedestrians who are blind. Six alignment cues were evaluated in a simulated crosswalk environment in which crosswalk angle was not always in line with ramp slope. The effectiveness of each cue is reported and implications are discussed.
