TSC Resources (drawn from all subsections listed above)
Crosswalks Project resources
"Marked Crosswalk Dilemma: Uncovering Some Missing Links in a 35-Year Debate," Meghan Fehlig Mitman, David R. Ragland, Charles V. Zegeer. Presentation at the 2008 TRB Annual Meeting.
"Driver/Pedestrian Understanding and Behavior at Marked and Unmarked Crosswalks:" an extensive study of pedestrian and driver knowledge of right-of-way laws. Several statistically significant differences in marked versus unmarked crosswalks were identified. Includes research and recommendations and analyses of countermeasures to improve pedestrian crosswalk safety. (July 2007).
