Shortest versus fastest distance Yournavigation.org

OpenStreetMap Questions and Answers
#1

I am an user of Yournavigation.org’s API. I am interested in the shortest distance and the corresponding time between two points.

However, it seems like the the shortest route in Yournavigation.org is always faster than the fastest route. For instance:

The route (motorcar) from Amsterdam to Rotterdam:

Option: Fastest
Info:
Segments:
0) length = 76.07 km, traveltime = 3602 sec, nodes = 789
Route:
Distance = 76.07 km
Traveltime = 3602 sec
OSM nodes = 789

Option: Shortest
Info:
Segments:
0) length = 66.78 km, traveltime = 2179 sec, nodes = 1442
Route:
Distance = 66.78 km
Traveltime = 2179 sec
OSM nodes = 1442

How is it possible that the shortest route (2179sec) is faster than the fastest route? (3602 sec)?

First: are you aware that the database for yournavigation.org is from September 2014 with NO updates so far??
Or do you have an own instance / server with recent map data for routing?

second:
I cannot answer the core question, but what is the result of shortest / fastest routing when you try other OSM based routing services or APIs listed on https://wiki.openstreetmap.org/wiki/Routing/online_routers ?
