How to Use This Calculator

Enter the number of vehicles in the convoy and average vehicle length (meters).
Set vehicle spacing (meters) — typically 50–100m on roads, 25m in urban areas.
Select road condition: Paved Highway, Secondary Road, Improved Dirt, or Unimproved.
Enter route distance to calculate arrival time and convoy column length.
Use column length and speed outputs for route clearance and traffic control point planning.

What each input means

Number of Vehicles: Total number of vehicles in the convoy.

Road Condition: Quality of the route road surface.
Route Distance: Total route distance from SP to RP.
Planned Halts: Number of planned rest or refueling halts.
Halt Duration: Average duration of each planned halt.
