Convoy Fuel Stop Synchronization Calculator

A convoy should plan around the vehicle with the shortest conservative range, not the fleet average. Subtract detours and a reserve from each vehicle’s estimated range, then choose a common stop interval below the minimum. This calculator models a simplified fleet from shortest and longest ranges; terrain, weather, towing, station availability, communication, and driver needs still matter.

Planning estimate only. Check measurements and real-world constraints before buying materials or making a commitment.

How the calculation works

The calculator applies this relationship to the inputs above. Keep every measurement in the unit shown.

shared stop interval = shortest estimated range × reserve factor − route detour allowance
Shortest vehicle estimated range420 km
Longest vehicle estimated range650 km
Convoy fuel reserve20 %
Route and station detour allowance35 km
Total convoy route1100 km
Planned stop interval300 km

Worked example

Use this example to check the calculator by hand before relying on a result.

1
Reserve 20% of shortest range
The convoy does not plan around an empty tank.
420 × 80% = 336 km
2
Subtract detour allowance
Station access and route variation consume range.
336 − 35 = 301 km
3
Compare planned spacing
The default interval is too close to the planning limit for comfort.
301 − 300 = 1 km margin

Assumptions behind the result

  • • Shortest range reflects trip conditions.
  • • All vehicles start each leg with intended fuel.
  • • Detour allowance is per interval.
  • • Stations can serve all vehicles.
  • • Drivers maintain communication and independent safety.

Mistakes that change the answer

  • • Planning from average fleet range.
  • • Ignoring detours to fuel.
  • • Choosing a station beyond the shortest vehicle’s reserve point.

Questions about convoy fuel stop synchronization calculator

Should the longest-range vehicle always stop?
A shared stop can simplify coordination, but operational needs may support staggered plans with clear communication and rendezvous points.
How should towing vehicles be handled?
Use their real towing consumption and tank range, which can be substantially below normal driving estimates.
Does this include driver rest stops?
No. Rest, meals, pets, charging, and legal driving-hour needs may require more frequent stops.
