The fares charged for the same trip often vary widely according to age of riders, method of payment and deals negotiated by groups that buy passes — plus surcharges may kick in when the price of fuel surpasses certain levels.
"It's confusing to the public and our operators, and we really want to streamline and simplify," Benson said.
"What we are talking about now is really a clean sheet, and coming up with a system that is simple, fair," he said.
Benson said the agency decided it needs to review its overall fare program after it recently studied, then discarded, a proposal to move to "distance-based fares," where people who travel farther would pay more instead of charging passengers one fare for trips of any length.
Benson said the study found that was technically possible for UTA, but the public opposed it because it would have made fares more expensive and complicated for many.
"So we decided to pause, take stock of everything and try to move forward with a comprehensive fare system" review, he said.
Bourdeaux said the agency is looking for ideas by studying fare systems used by similar-size agencies in Dallas; Portland, Ore.; Denver; Minneapolis, Austin, Texas; Cleveland; Houston; and Seattle.
She said the agency is studying different components of fares, including ease of use, promoting ridership, affordability, covering costs, what groups may deserve reduced fares, special fare zones and more.
Bourdeaux said a variety of options will likely be developed to allow for a discussion about the trade-offs that each offer.
She said focus groups and a public hearing process are also planned for potential changes.
