How to Measure Travel Distance?
Is there any situation where travel distance is not measured using right angles and travel parallel/orthogonal to walls? Also, how close must travel distance be measured from adjacent walls?

Is the travel distance for the purpose of developing life safety egress plans, fire hose coverage, or something else?

This question came in as travel distance for the development of life safety plans (means of egress).

NFPA 101 gives guidance on measuring travel distance for means of egress:

Let me answer from the perspective of a commercial plans examiner that reviewed to the 2012 IBC.

One typical example of measuring travel distance (TD) in a diagonal approach is in a mall structure. Since mall concourse/corridor is wide and normally open for occupants to stroll, angular measurement of TD is possible. Also on a driveway of a parking area it is typical to do a TD diagonally and very much acceptable with the authorities having jurisdiction (AHJ).

I'm working on an exercise studio with one big open room and dealing with a plan examiner who insists travel distance is measured along walls leading to an exit, rather than diagonally across the space. To me this is absurd. Thoughts?

You probably have the answer by now. It's about life safety, you should always measure the maximum possible path. Occupants may be using the wall to find their way in a dark or smoke filled building.
