Our project is on a college campus that is within 0.15 mile of a bus stop. It is served by one bus system. It's a public, not student-only system. However, there are five different bus routes that use this stop: some for campus, some for the greater town, and one that connects to nearby towns. Some of the routes are year-round. Some are business day only and some are late-night.

Does "bus line" mean a service like Trailways or Greyhound or MTA or CTA, etc. Or does "bus line" mean a bus route?
