School Bus Route Planner

Bus route capacity is calculated by adding the total number of students boarding at each stop along the route and comparing that figure against the seating capacity of the assigned bus. The occupancy percentage is derived by dividing total students by bus capacity and multiplying by 100. For example, if 38 students are spread across 6 stops and the bus seats 40, the occupancy is 95%, which sits in the "near capacity" zone. Schools should target 75–85% occupancy to leave buffer for last-minute additions, driver comfort, and safety regulations that may restrict standing passengers on school buses.

Standard school buses in India typically seat 36 to 54 students depending on the body type, mini-buses seat 20–30, while full-size school buses seat 40–66. In the US, a Type C school bus seats 48–78 students depending on seating configuration and student age (smaller children allow three per bench versus two for older students). Most school transport policies recommend operating buses at no more than 90% of rated capacity to allow a safety buffer. For routes with very young children (pre-primary and primary), always check local transport authority guidelines as many jurisdictions mandate seat belts and lower per-bus capacity.

The most effective approach is geographic clustering: group students who live within a 500-metre radius of each other into the same stop, then design routes that form a logical loop or corridor rather than backtracking. Once stops are mapped, assign students starting from the furthest stop from the school (so the first pickup is farthest out, and the bus fills progressively), this ensures early-pickup students are seated while later-pickup students board. Use occupancy analysis to balance loads across parallel routes; a route that is 110% occupied while a neighbouring route runs at 60% indicates redistribution is needed.

When a route is over capacity, you have three options: split the route into two services (same bus makes two trips at different times), reassign borderline stops to an adjacent route with spare capacity, or deploy a larger bus. The fastest fix is a stop-level reassignment, identify the last two or three stops that push the count over capacity and move those students to a nearby route. If no parallel route has spare capacity, a staggered schedule (an early bus and a late bus serving the same corridor at different times) can double the effective capacity without adding vehicles. Always recheck occupancy calculations after any redistribution.

A complete school bus route plan should document: the route name or number, the assigned bus number and driver, each stop in pickup sequence with the stop name and GPS coordinates, the expected number of students at each stop, the cumulative student count after each stop, the estimated arrival time at each stop, and the total route duration. It should also record the bus seating capacity, current occupancy percentage, and a status flag (optimal, near capacity, or over capacity). This information should be reviewed at the start of each academic term and updated whenever student addresses change or new enrolments occur mid-year.
