Transit Headway Capacity Calculator
Convert round-trip cycle and vehicles into even headway and planning passenger capacity.
What would you like to do next?
Connect fleet count with a simple service interval
Enter round-trip cycle minutes, vehicles in service, planning capacity per vehicle and a working maximum load factor. The calculator divides the cycle evenly across vehicles, converts headway to departures per hour and applies the selected load factor to directional capacity.
Test the schedule against real operating variation
Layover, terminal constraints, operator rules, deadheading, bunching, traffic, breakdowns and uneven direction demand can change achievable service. Capacity definitions must also preserve accessibility and operating policy. Use observed running-time distributions and the approved timetable process before changing a route.
Frequently asked questions
How is headway calculated?
Round-trip cycle time is divided by vehicles in service.
Is every vehicle assumed evenly spaced?
Yes. The result is a nominal even-spacing scenario.
Does capacity equal actual ridership?
No. It is a supply scenario using entered assumptions.
