Street Segment Gap Methodology
Every street segment across the 9-county DVRPC region was analyzed to find gaps in the sidewalk network. For each segment, the length of parallel sidewalks was identified and divided by the segments's length. The resulting ratio was classified into one of the three groups shown in the legend.
The walking time to the three nearest public transit stops was calculated for the start and end points of every sidewalk segment across the 9-county DVRPC region. This includes all modes operated by SEPTA, NJ TRANSIT, and PATCO.
The number of minutes to the nearest stop is shown with each point's color. Red points highlight sidewalk segments where it's impossible to walk to any transit stops solely via the sidewalk network.
For every rail station across the 9-county DVRPC region a set of one-mile "walksheds" was calculated, one using the sidewalk network and the other using the vehicular street network. These two areas were compared as a ratio to create a "sidewalk score," highlighting stations where sidewalk accessibility is limited or non-existent.
Clicking on a rail station will zoom in and show the two associated walksheds.
Every sidewalk segment was grouped with all adjacent sidewalk segments. The result of this analysis is a set of "islands," with each one representing a single portion of the network where a person could walk from one end to another entirely on sidewalks (and crosswalks).
Each island is represented with a distinct color. Hovering your mouse over an island will identify the size of the island in linear miles.
