Evaluating Sidewalk Infrastructure and Durability

Abstract

USDOT 69A3551947137National Transportation Library (NTL) Curation Note: As this dataset is preserved in a repository outside U.S. DOT control, as allowed by the U.S. DOT\u2019s Public Access Plan (https://doi.org/10.21949/1503647) Section 7.4.2 Data, the NTL staff has performed NO additional curation actions on this dataset. The current level of dataset documentation is the responsibility of the dataset creator. NTL staff last accessed this dataset at its repository URL on 2023-08-16. If, in the future, you have trouble accessing this dataset at the host repository, please email [email protected] describing your problem. NTL staff will do its best to assist you at that time.This project leverages advances in technology and increasing access to high-resolution remote sensing and spatial data to develop methods for inventorying sidewalk characteristics and static obstructions across an entire major city. In part 1 of this effort, the authors analyze city-scale sidewalk availability, width, and land coverage calculated from spatial data from aerial imagery (planimetrics). The authors then determine how much of a difference accounting for static obstructions makes when measuring the clear width of sidewalks in one city. Part 2 then combines planimetric sidewalk data with vehicle and pedestrian trip big data to develop a methodology to prioritize city areas in need of pedestrian infrastructure attention. The results show an overall deficiency of sidewalks and indicate that deriving sidewalk availability, average width, and minimum clear width are feasible at the city scale. This zip file is approximately 80.71 MB. The following file types are standard for GIS mapping software: SHP, DBF, PRJ, CPG, SBN, SBX, and SHX. Because the files pertain to map layers and images, they are best viewed using the software that the team used or with any open source 2D and 3D mapping software. XML files are a markup language file that holds data. They can be opened using open-source programs such as Notepad or any text editor
