If there are 3 places a transit system should stop at, it's airports, universities and downtowns.
This is because these are 3 hubs of jobs and places that people want to be but are also unlikely to have cars at because students are broke, people in downtowns don't need cars, and travellers by plane lack cars as well fod obvious reasons.
This is why transit systems like the Cincinnati Streetcar fail as while it meets the downtowns needs, it f ails to provide real connections, if it were to be extended to UC then it would be a much more functional transport system as it would give mobility to people instead of acting as a people mover
