Pedestrian facilities at interchanges

Interchanges are designed to improve the efficiency of vehicular traffic operations on roadways. Pedestrian facilities at such locations have not been of primary consideration. The objective of this dissertation was to develop design guidelines for pedestrian facilities at interchanges. The development of the guidelines was based on a review of the literature and a survey of state departments of highways to determine the state-of-the-art in current practice.; Both the literature review and the survey of the state departments of highway were synthesized. Based on the synthesis, a framework for design guidelines were developed. A number of field studies of pedestrian behavior at interchanges were also conducted to support the development of the design guidelines.; The guidelines address the design and use of sidewalks, crossings, traffic control devices, and illumination for pedestrian facilities at interchanges.
