This is the documentation for
network_routing, a Python package developed by DVRPC to produce the datasets shown in the Sidewalk Gap Analysis Explorer.
This work was conducted using DVRPC’s pedestrian facilities inventory, a GIS dataset that inventories sidewalks, curb ramps, and crosswalks across the nine-county Greater Philadelphia region. Explore the data and help plan for a pedestrian-friendly future at walk.dvrpc.org.
This codebase facilitates the creation and analysis of routable networks, using any topological network dataset including:
- DVRPC's sidewalk network
- DVRPC's Level of Traffic Stress network
The codebase is broken up into four primary modules, each with its own command-line-interface (CLI):
dbcontrols all data I/O
accessmanages all accessibility/routing analyses
gapshandles analysis processes that don't use network routing
improvementsgenerates tables showing the missing gaps in the sidewalk network
It builds on top of a variety of libraries, including
This codebase requires the following software:
