Other Analyses

Network analysis configurations

There are a number of other accessibility analyses defined within

./network_routing/accessibility/cli.py

These can be run in a one-off fashion using the access command. For example, to execute the analysis for the PART project you can run:

access part-sidewalk
access part-osm

Each of these configurations defines the network edge table, the Point-of-Interest table, and other analysis parameters like search distance, snap tolerance, and output schema and table names.

Draw missing sidewalk segments

To draw the missing sidewalks (i.e. "gaps") run the following command:

improvements draw-missing-network-links COUNTYNAME

Replace COUNTYNAME with the name of the county you want to analyze, like "Montgomery", "Camden", etc.

Note: this command can only be run after first running gaps classify-osm-sw-coverage

The result of this script is a set of lines that overshoots what's needed. To clean this dataset up, run the following command:

improvements feature-engineering --erase

After running this script, the outputs can be exported with:

db export-geojson regional_gaps
