How to provide custom time to travel between the locations?

I have 2D array of distances between geo-locations . see the link Map box time to travel

How do I inject this to build the problem in jsprit .

Solution

  • you can try this : 

    VehicleRoutingTransportCostsMatrix.Builder vrtcMatrix;
VehicleRoutingTransportCostsMatrix costsMatrix;
vrtcMatrix.addTransportDistance(String.valueOf(fromId), String.valueOf(toId),
                                (double) distance.inMeters);
vrtcMatrix.addTransportTime(String.valueOf(fromId), String.valueOf(toId),
                                (double) duration.inSeconds);
costsMatrix = vrtcMatrix.build();

    Then 

    VehicleRoutingProblem.Builder vrpBuilder = VehicleRoutingProblem.Builder.newInstance();
    vrpBuilder = vrpBuilder.setRoutingCost(costsMatrix);

    You have to set it between all of your combinaison of points. Use a distance matrix calculator to get a good distance/time estimation.

    Hope it helps.
