Denver Metropolitan Pedestrian Networks

A series of pedestrian networks in the Denver metropolitan area All files are uploaded in a zip archive file format- they will need to be extracted before opening in ArcGIS, QGIS, or similar programs. In general we recommend using the gdb source rather than shp sources for data due to some data loss and field truncation in the shape file archives. Projected Coordinate System NAD 1983 HARN StatePlane Colorado Central FIPS 0502 (US Feet) WKID: 2877 Sources DRCOG Sidewalk Centerlines 2022 (link) Paved sidewalk centerlines delineated from 2022 aerial imagery, along with network features such as crosswalks and likely missing sidewalks. This has been produced every two years since 2014. It includes a type field that differentiates pedestrian path types: Sidewalk: a paved path for pedestrians; most often on the side of the road Crosswalk: a marked (painted) part of the paved road where pedestrians have right of way to cross. Crosswalks within parking lots are not included. Possible missing sidewalk: an area on the side of a road where a sidewalk appears to be missing. An indication of a missing sidewalk would be existing sidewalks in the surrounding blocks. This feature should not be paved and should not cross the road. Segments with this attribution can be delineated up to 650 feet to maintain connectivity in the layer. Possible missing crosswalk: a crossing of a major street that doesn’t currently have crosswalk paint markings. Major streets are indicated by road surface markings. Segments with this attribution can be delineated up to the width of the street to maintain connectivity in the layer. Other path: is a line segment that doesn’t meet criteria for the other types but needs to be included in the data set to maintain connectivity in the layer. An example would be a sidewalk or possible missing sidewalk that breaks at a parking apron. The section that covers the parking apron would be an “other path.” Segments with this attribution can be delineated up to 650 feet to maintain connectivity in the layer. Best‑fit line: a straight feature drawn through a decorative sidewalk pattern (e.g. on a school campus). It indicates that a sidewalk is there but does not trace all pedestrian possibilities. Harvard Streets (link) A national public street network dataset, clipped to a ½ mile buffered RTD boundary and excluding streets with the type motorway, motorway link (ramps), and motorway & motorway link. Edits from source file performed by Karlyn Russell‑Carlson. Caveats While the sidewalk data is provided by DRCOG, not all areas within the DRCOG boundary had sidewalk data collected. Please reference the sidewalk_extent_2022 feature class for a polygon representing the extent of the sidewalk data. The sidewalk data does “not include private sidewalks (i.e. serving individual residences, contained within campuses, malls, apartment complexes, mobile home parks, or commercial complexes) except where the sidewalk maintains connectivity with the public sidewalk network” (quote from DRCOG documentation). Additionally, it does not include crosswalks in parking lots. Due to this, the below datasets may not have a complete representation of the pedestrian network in large parking lots. For example, below is a screenshot of the ideal network in green surrounding the Target and PetSmart commercial development near Colorado Boulevard and Alameda Ave: While sidewalk data has been produced every two years, a longitudinal study may be difficult. Data in the 2014 and 2016 versions appeared to lack many sidewalks and were primarily public trails upon a brief review.
