This is something I wish my local transit authority (or someone with the skills) would do, create a map which included key high frequency bus lines. I'd include basically everything which had 10 minute frequency during the bulk of day, with something indicating which had (less frequent of course ) overnight service. It'd be a bit trickier to pull of well (can't have information overload), but including key corridors which achieved 10 minute headways because of service duplication, even if individual bus routes along the corridor were more infrequent, would be good as well.
For various reasons people are hesitant to ride buses. But they're not so bad! One barrier is route uncertainty, and adding key routes to the main system map is a way to minimize that.
