That is a very complex question. You may add bicycle to the vehicles 
too. Animals and humans .. too?

Soft surfaces may not support the vehicle weight (given a tyre size and 

Slippery surfaces may no provide enough traction.

Rough surfaces may though a vehicle off the require path.

Very rough surfaces may require lots of ground clearance. This might be 
combined with the above 'rough surface'?

So that would be 3 measures .. they all have objective measures that 
give numbers.. very few people would be able to measure and map them 
though. And, as you say, they all change with weather and traffic. The 
first vehicle to cross sand has a hard crust .. the next has a softer 
surface.. after quite a few vehicles you get to a compacted surface... 
with a covering of soft sand that has fallen back in to the grove. 
Quantifying it is very difficult.
