The use of three-dimensionally (3-D) marked crosswalks is an emerging transportation policy practice in the United States. This innovation has ... read moredrawn attention globally initiating discussion across the field of urban planning and other related disciplines. Municipalities, industry experts, and users have shared first-hand experiences in periodicals. These testimonials question the validity, and safety related to the use of 3-D crosswalks. Concerns regarding pedestrian and driver safety have been brought to the forefront probing, the use of 3-D crosswalks as a potentially effective traffic control device. Without a strong body of research on the topic, planners have little to no data or findings to inform professional decision making on the use of the 3-D crosswalk design. Using 3M's Visual Attention Software (VAS) an eye-tracking emulation software, images of 3-D crosswalks were analyzed. The findings produced in this study serve as a strong basis for understanding 3-D crosswalks as a traffic control device.read less - ID:
