If NO ONE left Howard Beach for Jamaica, the two stations have entirely distinct service areas, and the drop in traffic at Howard Beach is that much more dramatic.Agreed. However, you are still not considering the fact that Jamaica added to the pie JUST by being added. I have to keep these even numbers for illustrative purposes, but it works the same way even if the numbers are different as they of course are. And of course, I am just using 25% and 4 ways in as a base as it keeps it simple: Pre-Airtrain: Whole pie: 100% - 4 slices -Howard Beach: 25% come in -Ground transportation: 25% come in -Airport Coach: 25% -Taxi: 25% Post Airtrain, the next day, right away Jamaica skews that as it's a 5th item thrown in: Whole pie: 100% - 5 slices -Jamaica: 20% -Howard Beach 20% -Ground - 20% -Airport Coach - 20% -Taxi: 20% Just by adding Jamaica, and not even cannibalizing passengers from other points, every percentage dropped. |
