What is a “buffer time” in transit scheduling?

Buffer time in transit scheduling refers to the extra time that is intentionally added to schedules to accommodate potential delays. This is a crucial element in transit planning as it helps maintain service reliability and ensure that schedules can be adhered to, even in the face of unexpected occurrences such as traffic congestion, mechanical failures, or passenger loading times. By including buffer time, transit authorities can improve the punctuality of services and enhance the overall travel experience for passengers.

Using buffer time effectively allows for a more realistic schedule that takes into account variables that may not always be predictable. This way, even if a delay occurs, the service remains on track, and passengers can have a better expectation of arrival times.
