In the current master and RC1 you can specify multiple vehicles even if
CH is turned on (although still only the first vehicle is prepared).
Before you had to disable CH to use multiple vehicles.
In my case CH is turned off and I still get this exception when I issue
a routing request. Do you think is it possible?
Thanks a lot!

Peter,
thanks for the hint, I used the location index to find the closest
edge and it worked. I have a couple of additional questions:
- After having implemented a custom weight, I'm wandering if it's
possible to set a threshold in the length or travel time over which a
tentative path is discarded (e.g., using astarbi)? Note that the
implemented custom weight doesn't use distance nor speed as measure.
- What is the meaning of the method getMinWeight when, for example,
astarbi is used?
- Is it possible to specify more than a value for the property
graph.flagEncoders (e.g., BIKE, FOOT) ? When I tried I got this
exception: java.lang.IllegalStateException: Multiple encoders are
active. cannot return one:bike,foot
What am I doing wrong?
Thanks a lot!

Hi Rossano,
while import you'll have to store the mapping from osm node to internal
node, then you can easily do what you proposed. A more generic solution
would be to use GPS locations instead of OSM nodes to specify the
weighting and then using the location index to lookup the closest edge.
Then you have the edgeId to weight mapping which you could either put
into the edge directly, or just use a double array where the edgeId is
the index. Or use DataAcess which is a storable array for many purposed.

Hi there,
suppose I have an external file with this format
OSM_NODE_ID1 OSM_NODE_ID2 w1
where OSM_NODE_ID1 and OSM_NODE_ID2 are two OSM node ids and w1 is a
double that represents a custom weight. What I'd like to do is:
1) Find the edge gh_edge_id in the GraphHopper internal data structure
that corresponds to the the edge OSM_NODE_ID1->OSM_NODE_ID2
2) Create a data structure that maps the relation
gh_edge_id w1
in a way that at runtime in a custom Weighting class I can retrieve
the value w1 when the corresponding edge is visited.
Which is the best approach to tackle this problem?
Thanks a lot for your support.
