Generating data

Install requirements

• Java
• uv (Python package manager - Install via curl -LsSf https://astral.sh/uv/install.sh | sh)
• R
• renv (Install via Rscript -e "install.packages('renv', repos='https://cloud.r-project.org/')")

Prepare data

> ./download_streets.sh
> ./download_timetables.sh
> ./otp.sh --build # (Caches street graph, use --buildStreet to rebuild)

Munro route starting coordinates were downloaded from walkhighlands (see data_sources/walkhighlands) and checked into this repository, so you should not need to redownload them.

Transit data trimming

The ./download_timetables.sh script automatically trims both bus and rail transit data to the next full week (Monday-Sunday):

• Bus trimming uses a Python script (with uv for dependency management) that filters GTFS with gtfs-kit
• Rail trimming uses UK2GTFS's built-in gtfs_trim_dates() function in R
• Both sources are trimmed to the same week to ensure consistency
• ./otp.sh --build extracts the week start date from the trimmed GTFS and writes it to otp/transit_week.txt
• The analyzer reads this file to determine which Wed/Sat/Sun dates to query

To update to a newer week, re-run from ./download_timetables.sh onwards. The trimmed transit data represents a fixed week and won't change unless you re-run the workflow.

Analyze data

./otp.sh # Run OpenTransitPlanner in one terminal
./analyzer/analyze.sh # This script will take hours. If interrupted run it again to generate the rest.
