1, Keep as is. The Q30 runs on HHE by springfield for a reason...
2. That would make the Q12 REALLY long..
3. This is my area of expertise. Well the crosstown isn't needed. That area is pretty dead. The Q84 doesn't do that great on 120 Av, its mostly residential. As for the Baisley segment, most people take buses TO jamaica. This "crosstown" wouldn't preform very well. If one wants to go to JFK, the Q3 is there for a reason. Oh and this route would be super long if it was a segment of the Q27 which is already pretty long itself.
4. Those stops are good if the route was to be made.
5. Nope, nope, nope, those 4 routes are separated for a reason! Doing that would make 2 really long routes for no particular reason.
6. BusTime should come to Queens ! and yes I like the idea of signal priority.. A lot of lights on certain routes don't connect together (one on one block will be green, next block will be red) as I've noticed
