Lot of missing travel times - TimeService

[kofronpi]

Around 10 to 20 % of my requested travel times are missing a duration (-1 response from the TimeService server), even when I greatly enhance the max_routing_time ( up to twice what I know is as a correct threshold to reach the POI !).

Can you give me pointers to how to reduce the miss % rate to an acceptable threshold such as 3-4% ?

Is it possible to be because of the location of target POI ? (too far from a road, network, etc.)

I'm using the "/westcentraleurope/v1/time" endpoint.

Thank you.

Could you provide sample CURL requests? What I see so far is that maxRoutingTime is written wrong. But in general this should not happen.

@gerbsen oh, you are right, I messed up with the key maxRoutingTime. The behavior is weird though because the results without routing duration are consistent request after request.

gives me none :)

I'm closing this for now as I will investigate the %miss rate on a large number of results, and I'll come back to you if necessary.

Thanks !
