what is a route taxi

[Rob]

Booger - that means that you chartered the taxi - essentially changing any "route" taxi into a "charter" taxi....

For anyone not familiar with the difference between route and charter is there a distinguishing mark, sign, color of plate that would identify one from the other?
All I can remember from my trip is they would beep the horn as they approched to ask if you needed a ride.
