Transit system planning
Terminal recovery time can protect the next bus trip
Recovery time at the end of a route can absorb ordinary delay, support operator needs, and help the next trip begin on schedule.

A bus that reaches the terminal late can carry that delay into every following trip unless the schedule includes room to recover. Terminal recovery time is not simply idle time. When it is planned from real operating data, it gives the service a chance to reset while still protecting useful frequency and connections for riders.
Separate running time from recovery time
Running time covers movement between scheduled points. Recovery is the time at the end of a trip that can absorb routine variation and prepare the vehicle and operator for the next departure.
The Federal Transit Administration's National Transit Database glossary describes layover or recovery time as time scheduled at the end of a trip to allow recovery from delays and preparation for the return trip.

Review actual terminal arrivals by weekday, time of day, direction, and season. A single average can hide a morning bottleneck or a school dismissal period that regularly consumes the scheduled recovery.
Look at the distribution, not just the worst trip. The goal is to understand normal variability and identify persistent causes that should be fixed instead of covered with more schedule time.
Check the terminal conditions
Recovery only works when the terminal has a legal stopping location, enough vehicle space, and reasonable access to operator facilities. Field observations can reveal blocking, circulation conflicts, or a scheduled layover that cannot occur as designed.

- Next-trip departure performance.
- Operator break and relief-point needs.
- Terminal capacity and nearby connections.
Test the network effect before changing the schedule
Adding recovery can improve reliability but may require another vehicle or reduce frequency if cycle time increases. Test the change against fleet needs, operator work, timed transfers, and passenger waiting time.
Cathay Express Transportation can support transit system evaluation and service planning studies that connect field conditions, operating data, and schedule options without assuming that one recovery-time rule fits every route.
