Back-up turning templates

[vmirat]

I use TURN.lsp in Autocad for vehicle turning templates. However, these only figure the forward movement templates. I need to know what the vehicle path would be for a WB67 backing up in a 90 degree turn.

2 researchers at Villanova put together a study entitled
"Tractor-trailer reverse movement path". They created a template for the rearing manuever.
