regarding Chapter 17: Urban Street Segments

I am trying to use Equation 17-2 to calculate Base Free-Flow Speed. I would like to know the exact definition of "access point approaches" used in the calculation of the adjustment factor for access points. E.g. If you have an off-ramp in your segment, would that be considered an access point approach?

Thanks.
