Shuttle Bus Requirement Calculator

Work out shuttle bus requirement instantly with clear inputs, formula shown and shareable results.

About Shuttle Bus Requirement Calculator

Trips needed divides passengers by bus capacity, trips per bus divides the time window by the round trip, and the fleet size is the ratio of the two. Round trip time including loading is what drives the fleet, which is why shortening the route or speeding up boarding beats hiring larger buses.

Formula

Fleet size

buses = ceiling(total trips / floor(window / round trip time))

Worked example

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Shuttle Bus Requirement figure worked out?

buses = ceiling(total trips / floor(window / round trip time)). Trips needed divides passengers by bus capacity, trips per bus divides the time window by the round trip, and the fleet size is the ratio of the two.

Why does this matter?

Round trip time including loading is what drives the fleet, which is why shortening the route or speeding up boarding beats hiring larger buses.
