Synthesis of Information Related to Highway Practices. Topic 50-10. Availability of Pedestrian Infrastructure Data For Routing and Network Analysis

Non-motorized travel is becoming increasingly important for transportation planners and engineers. However, to plan for and encourage non-motorized travel, and particularly walking, data is needed. The question of "Can I walk from here to there?" is largely dependent upon one's personal abilities in relation to the existing infrastructure, topography, and land uses through which one may travel from point A to point B, and thus the relationship between these aspects influence a person's decision to utilize non-motorized travel as well as the route ultimately chosen. While some cities are now collecting data about their sidewalks and paths, pedestrian signals, and other pedestrian-related infrastructure, these data are not stored in consistent formats, may not be accessible to others, contain a wide variety of different attributes, and thus are not typically useable by most of the people who need that information to make routing decisions. Sidewalk data is also needed for a wide variety of planning, research, engineering tasks and asset management. Cities and other government agencies frequently are required to perform sidewalk inventories and assessments, and, indeed, should be maintaining and updating a Transition Plan in compliance with the Americans with Disabilities Act. The objective of this synthesis is to document the state of the art in collecting, managing, delivering, and using sidewalk and other pedestrian infrastructure data. Information to be gathered will include but not be limited to: (1) Summarizing the different mechanisms for obtaining, storing, delivering, and using data on sidewalks, other non-motorized pathways, accessible pedestrian signals, transit stop features, and other pedestrian infrastructure; (2) Summarizing the available tools and methods for collecting those data, and document the advantages and disadvantages of each; (3) Summarizing the types, variables, attributes and formats of data being collected; (4) Documenting how agencies and others currently use these data and what limitations currently exist in data usage; (5) Describing resources for working with communities to collect and vet that data; (6) Documenting how agencies may both share data and maintain sensitive aspects of those data internally; (7) Identifying uniform core data and formats that can be shared with technology developers and mapping systems to provide pedestrian information useful to travelers; (8) Summarizing the availability of tools (and their advantages and challenges or limitations) that can be used to help manage the routine updates to pedestrian infrastructure data that can be provided though public input (e.g., what do you do when the public tells you that your data are wrong?); and (9)Identifying the available research on routing people of differing abilities, including the data required to perform that routing, and the algorithms available to perform that routing. Information will be gathered through a comprehensive literature review, a survey of departments of transportation (DOTs), and interviews summarized into case examples.
