An educational planning example with stated assumptions. Results vary with the actual route, schedule and cost.
| Variable | Assumption |
|---|---|
| الركاب / Passengers | 300 |
| المقاعد / Seats | 30 |
| الدورة / Cycle | 30 min |
| النافذة / Window | 60 min |
| رحلات الحافلة / Trips per bus | 2 |
| الحد الحسابي / Calculated minimum | 5 |
A defined window and cycle
Assume 300 guests at one pickup point, ready vehicles and 30 confirmed passenger seats per trip. A 30-minute cycle includes boarding, outbound, unloading, return and waiting, within a 60-minute window. This is not an operating commitment or a record of an OGAS event.
The basic calculation
The window fits two complete cycles. One vehicle moves 30 × 2 = 60 passengers under the assumptions, so 300 ÷ 60 = 5 vehicles. This is a mathematical minimum with no margin for a delayed cycle or higher demand.
What if the cycle becomes 35 minutes?
A conservative count of complete cycles within 60 minutes now allows one trip per vehicle, giving a calculated ten vehicles. A timed real-world schedule may distribute movements differently, but requires actual arrival and departure checks. An average is not a guarantee.
From arithmetic to a site plan
Review boarding-area capacity, guest arrival patterns, walking time, bottlenecks and vehicle staging. Discuss reserve capacity or a wider arrival window based on actual conditions. The calculator lets you vary basic assumptions to start a discussion, not replace a site review or approved plan.
Why seats multiplied by trips is not enough
The equation assumes vehicles can board and depart within the same cycle. If only one bus can load at a time, others may queue and timings change. Uneven guest arrivals can also send trips below full capacity. Review loading-area throughput, arrival patterns and the timetable alongside the arithmetic. Five vehicles alone do not prove 300 guests will arrive within the hour: the result depends on the stated assumptions and a realistic site schedule.
Turn the example into a real event brief
Use one table for passengers, origins and required arrival time, then add the estimated cycle and how it was obtained. State whether it was measured on site or is a broad estimate. Include return demand, session endings and vehicle staging. Ask about reserve capacity or a wider window when the plan leaves no flexibility. The team can then discuss vehicle numbers, classes and timetable rather than only total attendance.
- Passengers by origin and arrival window.
- Actual or required passenger seats, excluding the driver.
- Boarding, outbound, unloading, return and waiting time.
- Boarding-area capacity and staging space.
- Departure, coordination and required flexibility.
