Maybe I'm not understanding what you mean but isn't this just... a shared calendar? You have a work calendar which is public and other people can open to view your availability, and propose meeting times. And vice-versa you can see their calendar. Modulo your problem with travel times (but calendars have location info, so hacking something where the travel time between two consecutive locations is accounted for should not be too difficult). So I don't quite understand where "AI" fits into this.
