I’ve developed GTFS routing application using GraphHopper (Open Source Routing Engine) but I’ve got a problem. According to departure time I’ve got different best routes but I can’t get alternative routes in some cases.
For example when I request routes for all vehicle types then I receive only 2 result routes (subway and walk) but all alternative routes (with bus, tram, trolley legs) have lost. If I execute this request for all vehicle types excluding subway then result contains another 2 routes.

For configuring request vehicle type I use Request.setBlockedRouteTypes(). I noticed that GraphHopper finds all possible routes but hides alternatives in some cases.
So I need to:

• configure GraphHopperGtfs (may be Request) to get all the results in 1 response (including all alternatives)
• find PMap keys description (source code or docs) for configuring request (e.g. maximum result count, minimum / maximum transfer time).

Thanks!
