Generally what happens in cities with poor transit, is that people stop using them. Then the transit authorities look at their statistic dashboard, see "oh, bus route XYZ is almost empty. Means we can cut it!" and things just get worse.
Happened in my hometown. There was a bus that would get me straight to the subway, and during peek hour it would come every 3 minutes (ie: the buses were often back to back). They were all jam packed, too.
They eventually made changes to the route to "optimize" things. The route was split in 2 somewhat different routes, and came half as often. They forgot that not everyone went to the subway (so going from midpoint to midpoint was no longer possible, as the routes didnt link) and that 6 minutes during peek hour was ok, but it meant 1 HOUR wait off peek time.
During peek hour, since the routes were not longer as useful unless you wanted to hit the subway, half or so of the riders just stopped and used alternatives. Off peek hour you were lucky to see 1 person in either bus.
Eventually they just cut one of the routes and the second one was only running during peek hour at 30 minutes interval for lack of riders. It became totally useless.
