"Uniformly distributed" : the number of passengers is the same for every time of day

"Normally distributed": number of passengers versus time of day roughly looks like a bell-shaped curve, a Gaussian.

I hesitated writing this, pushing the pedantry up a notch, but then considered spacecraft crashing into Mars due to failure in technical communication, and recalled colleagues with college degrees in computer "science" who rejected the paradigm of Evolution of species as "only a theory", so here I am writing it down to remind myself of the difference between normal and uniform distributions.

Also, I worked briefly with some Ph.D. Queuing Theory people that one time.

Maybe there should be an academic discipline of "Commuter Science".
