alt Hacker NewsPeople always think that 'dynamic' is some magical solution. The reality is where people live and go doesn't change that fast. And once a bus route exist and people use it, you need a very good reason to remove it. And stations almost never move.
Re-planning your network once a year is plenty.
More importantly, if the routes do not change often you can plan around them. If the routes change all the time you never know if you can use them today and so you soon give up even checking.
