Abstract:

There have been controversial perceptions with respect to the use of marked pedestrian crosswalks at unsignalized intersections over the years. Several agencies tend to prefer marked crosswalks at most locations with the expectation of improving pedestrian mobility and safety. However, several studies conclude that marked crosswalks actually involve higher pedestrian accident rates than unmarked crosswalks. Such controversial claims make it difficult for state and local agencies to develop policies pertaining to pedestrian crosswalks. Existing guidelines for determining marked and unmarked crosswalk types are normally presented as descriptive statements or mostly relying on a single dominate factor like pedestrian volume. One of the major issues lies in the lack of comprehensive consideration and interpretation of all potential variables. A new guideline is presented to help select marked and unmarked crosswalks at unsignalized intersections with no traffic signals or stop signs on the major street approach. The guideline is based on a combination of revised multi-criteria decision analysis methodologies, PROMETHEE and the Analytical Hierarchy Process. A ranking score considering potential factors, including variables such as volume, speed limit, and pedestrian related crash records is produced to represent the likelihood of using a marked or unmarked crosswalk. The proposed guideline was further applied to a case study involving 32 unsignalized intersections in Nevada and the study showed promising results with the guideline.
