  • Abstract:
    The purpose of this research was to develop warrants for pedestrian over and underpasses or grade separated pedestrian crossings (GSPCs). Currently there are no established nationally acceptable warrants to serve as standards in deciding whether or not to build a GSPC. This research was conducted by first performing a literature review of existing practices and assessment of the state-of-the-practice to identify general types of warrants and existing warrants. A panel of advisers was formed to evaluate the practicality of the existing and candidate warrants. A behavioral study was conducted to ascertain pedestrians' perceptions of risks and inconvenience associated with use of sample GSPCs. Candidate warrants were developed and validated by contingency table and chi-square analyses of site characteristics of sample GSPCs. Proposed warrants, were developed from the candidate warrants consisting of threshold warrants for pedestrian volume, vehicle volume, and distance to nearest "safe" alternative crossing. In addition, requirements for at-grade roadway crossing barriers, artificial lighting, site topography to minimize elevation changes. nearby pedestrian-generating land use(s), and available funding were included. Seattle's priority ranking system (warrant) was proposed as a tool to prioritize potential GSPC sites for planning purposes based on pedestrian and vehicle volume, accidents, and other site characteristics.
