That probably makes sense. If your goal is to increase ridership / reduce emissions, you want to appeal tho those traveling every day. Each person you convert gives you 500+ trips a year. And of course people are most price sensitive to something they do every day.
On the flip side, if I travel a few times a year, on one hand I am "less important" because capturing my business won't lead to that many trips and on the other I am less likely price conscious. If I do something once a year, I might chose to drive regardless of train cost, just cuz I want to drive. Or, I may want to avoid driving so I am happy to pay the higher ticket cost anyway.
