Enter the distance traveled along the ramp (in) and the wheelbase of the vehicle (in) into the Ramp Travel Index (RTI) Calculator. The calculator will evaluate the Ramp Travel Index (RTI). 

Ramp Travel Index (RTI) Formula

The following two example problems outline the steps and information needed to calculate the Ramp Travel Index (RTI).

RTI = d / b * 1000

Variables:

  • RTI is the Ramp Travel Index (RTI) ( )
  • d is the distance traveled along the ramp (in) 
  • b is the wheelbase of the vehicle (in) 

How to Calculate Ramp Travel Index (RTI)?

The following steps outline how to calculate the Ramp Travel Index (RTI).


  1. First, determine the distance traveled along the ramp (in). 
  2. Next, determine the wheelbase of the vehicle (in). 
  3. Next, gather the formula from above = RTI = d / b * 1000.
  4. Finally, calculate the Ramp Travel Index (RTI).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

distance traveled along the ramp (in) = 80

wheelbase of the vehicle (in) = 69

RTI = d / b * 1000 = ?
