Having seen public transportation in Indianapolis from all sides, I recognize that there are successes and failures in our current system. It is extremely challenging to serve all classes equally. In order to be cost effective, it is necessary to attract all levels of commuters. Incentives for those of means are very different from those motivating the economically challenged. One common necessity use for safety and security. No one wants to ride a bus full of drug dealers and drunks. Those who can afford it will often opt for private transportation such as Lyft and Uber. It's unfair to expect bus drivers to police a full size or articulated city coach. One alternative is to have transit police attend random or selected routes. I think a more effective solution would be to re design hub and routes around a smaller shuttle. Not only good routing service be more effectively extended into currently unserved neighborhoods, but security would be much more easily maintained on a smaller vehicle. In fact, since automation is likely the way of the future, such vehicles might more easily be retrofitted.
These are just a few ideas.
