Accessibility - Proximity To Stops

The images below illustrate all active stop locations (overlayed on all routes). Active stops are those that actually serve one or more routes. There are stops defined in the databases that do not currently serve any routes.

Stop/Route Locations

  • 2017 (i.e., June 2018 and earlier) -1466 Active Stops
  • 2018 (i.e., July 2018 and later - 1444 Active Stops
  • BRT - 768 Active Stops

The following three images show the routes and stops for 2017, 2018, and BRT. Note that not all stops for the BRT system have been assigned.

Accessibility Heatmaps

The following three images illustrate the simplest possible heatmaps. These are just proximity to stops. For example, if an area is within 400 m of one active stop, it has a score of 1. If it is proximate to 2 active stops, it has a score of 2, etc. The plots are normalized by maximum score (i.e., scoren = score / max_score ) such that the max score in each plot is 1.0. This must be considered when visually comparing the plots.

Mode 1

  • buffer: 400m circle
  • stop pruning: no
  • distance decay: no
  • stop demand: 1.0
  • Added BRT stops: No

Accessibility Changes

Keep in mind that the accessibility heatmaps on this page consider only proximity to stops, and not the frequency of service at those stops. Also keep in mind that it appears that the BRT data does not have all stops assigned yet.

Red indicates an increase in accessibility, Blue indicates a decrease in accessibility.
