And good coverage.
They’re all up there. I’d probably go with
- Safety
- Frequency
- Availability (operating hours)
- Coverage
- Cost
Is that Cost in terms of building the system, or the time cost of using it?
Utility (or Time Cost, basically) seems like it should be up there, and I think that’s what you’re getting at with Frequency and Availability?
I think the time cost of using the system is the most important factor in designing a transit system.
Because every human has a finite amount of time. It’s our most precious resource.
Honestly if you’re willing to count a premature death in terms of a life containing X number of hours, I think that Safety factor can be put into perspective.
Obviously there’s also the enjoyability factor. A five minute trip during which your sunburn gets scratched mercilessly might not be better than a 15 minute trip in a jacuzzi.
But barring huge differences in comfort countering the effect, Time Cost of using should be the main thing, since everyone’s time is valuable.
