Routes for walking to school

This script generates maps to analyze the potential walking routes for students to their school.

• I excluded the addresses of the students from the repository.
• The actual route generation is done with brouter (using the safety profile) and OSRM (for the boundary polygons), those are run locally in docker containers.
• The basemap is pulled from Stadia Maps. The usage of the script is well within the free tier, you'll need an API key from them.

Data sources

• School location data is from: https://data-wi-dpi.opendata.arcgis.com/
• Madison Bike Level of Traffic Stress is from: https://data-cityofmadison.opendata.arcgis.com/datasets/cityofmadison::bike-lts/explore
• Student addresses provided by school.

Example figures

This script will generate a few figures:

A heatmap of student addresses:

A map of all the walking routes within the walk boundary:

A map of those walking routes colored by the level of traffic stress to bike

A map of cycling routes colored by the level of traffic stress to bike (with a 3 mile radius)

Using make

• make osrm-data: downloads the OpenStreetMap data for Wisconsin, and preproccesses it for use with OSRM.
• make osrm-container: starts the OSRM containers (backends and frontends) for walking and biking.
• make brouter-data: clones the repositories for brouter and brouter-web and downloads the segment data. It also builds the docker images for brouter and brouter-web.
• make brouter-container: starts the brouter containers (backend and frontend).
• make walk will run route_analysis.Rmd which calculates the walking routes using OSRM.
• make cycle-osrm will run cycling_route_analysis.Rmd which calculates the biking routes using OSRM.
• make cycle-brouter will run cycling_route_analysis_brouter.Rmd which calculates the biking routes using brouter.

Misc.

• Bike Level of Traffic Stress (LTS)
