There was some outcry about the elimination of service when UTA cut the number of bus lines along North Temple, a couple of years back. A third party was good enough to do an off-the-cuff analysis of service changes, denominated in "buses per day", rather then in bus routes. On that basis, North Temple did rather well when the big service change came.
The number of bus lines in an area a measure of complexity, not of service. More things to (mis-remember), more confusion, more avoidance.
