There are six requests with three different response schema. 
 
        Two departure requests, GetTimePointDepartures and GetDepartures, return NexTrip departure information. 
        GetTimePointDepartures requires Route, Direction and Stop as part of the URL. GetDepartures requires stopID 
 
        The GetTimePointDepartures and GetDepartures requests respond with NexTrip departure information formatted in these fields: 
        Actual:                    Transit vehicle departure prediction is using Actual(real-time) or scheduled information 
        BlockNumber:          Relates to 'block_id' in the Google transit feed data. 
        DepartureText:       Departure time if 'Actual' field is false, Countdown in minutes if Actual is true 
        DepartureTime:       Predicted departure time 
        Description:             Text describing transit vehicle destination as well as vehicle scroll (above front windshield) 
        Gate:                       Gate of predicted departure if applicable 
        Route:                     Route number for current departure 
        RouteDirection:       Direction of route 
        Terminal:                 Terminal letter of route - indicates variant of route 
        VehicleHeading:       Not currently in use 
        VehicleLatitude:       location coordinate field - decimal degrees latitude 
        VehicleLongitude:    location coordinate field - decimal degrees longitude 
 
        Route requests returns a list of routes with description and providerID. 
         
        The Route Directional (North, South, East or West), Providers (Metro Transit, MVTA, etc...) and Stop requests return lists of directionals by route, providers, or nodes by route and directional respectively.  The response schema is the same for all three request types: 
        Text:    String content - depending on request either Routes, Directionals, Providers or Nodes 
        Value:    String content - depending on request either Routes, Directionals, Providers or Nodes 
 
        Direction values: 
        1 = Southbound 
        2 = Eastbound 
        3 = Westbound 
        4 = Northbound 
 
        The value field in the response from the above requests can be used to compose the GetTimepointDepartures request URL 
 
        For example, to get a list of routes: 
         http://svc.metrotransit.org/NexTrip/Routes 
 
        To get a list of directionals on a route (21, in this case):
