Looking for a method to identify paratransit Trips that start and finish within bus route buffers

[PaulStrobis]

Hi Everyone,

I am attempting to only count the number of trips from my table data that start and finish in a 3/4 buffer around my 15 bus routes. 

I have table data with paratransit trips that span my entire county.  Formatted like this.... 

Tripdate    Tripid   Clientid    PromiseTim    PickX    PickY    DropX    DropY

I can display the pickups xy from the data, but not the drop xy's.  what am i missing?  Do they have to be separate tables?
                                        

Then I have my individual 15 bus route shape files. 

Is there a global way to only see the trips in buffer or do I need to repeat the process for each route?

Thanks all
