What you’ll learn

Build the service planDefine headway and explain why running and dwell time must reflect operating conditions.Schedules turn a service promise into target spacing and credible running times.
Protect and control serviceDescribe terminal buffers and compare controls that restore spacing under disruption.Recovery, layover, holding, and route interventions trade punctuality, coverage, and regularity.
Understand and measure reliabilityTrace bus bunching and connect headway measures to the rider experience.Delays can amplify through passenger loading; waits, crowding, and spacing reveal delivery.

Questions this course answers

What is recovery time intended to do?

Recovery time gives a vehicle and operator a planned buffer so small delays do not automatically carry into the next trip.

Put the basic bunching feedback loop in order.

A delay creates a larger waiting crowd; longer boarding adds delay, allowing the following vehicle to close the gap.

Why can a frequent route meet its timetable but still feel unreliable?

Passengers on frequent routes often depend on spacing rather than one published departure time. Headway adherence and actual waits reveal irregular service that a timepoint measure can miss.
