Good afternoon, I’m trying to get an optimized route matrix, but when I run the program, I encounter the following error:

Open Source Routing Engine
1

Error: Exception in thread “main” java.lang.IllegalStateException: time value for relation from [x=35.162316961336394][y=-106.51387457531828] to [x=35.11498075724412][y=-106.67752402116778] does not exist

Code:

private static void optimizeRoute(GraphHopper hopper) {
VehicleTypeImpl vehicleType = VehicleTypeImpl.Builder.newInstance(“vehicle_id”)
.build();

    VehicleImpl serviceStart = VehicleImpl.Builder.newInstance("0")
            .setStartLocation(loc(Coordinate.newInstance(35.162316961336394, -106.51387457531828)))
            .setType(vehicleType)
            .setReturnToDepot(false)
            .build();

    Service service1 = Service.Builder.newInstance("1")
            .setLocation(Location.newInstance(35.11498075724412, -106.67752402116778))
            .build();

    Service service2 = Service.Builder.newInstance("2")
            .setLocation(Location.newInstance(35.11526306515924, -106.55295605374026))
            .build();

    Service service3 = Service.Builder.newInstance("3")
            .setLocation(Location.newInstance(35.114527475312386, -106.56020801171813))
            .build();


    VehicleRoutingTransportCostsMatrix.Builder matrixBuilder = VehicleRoutingTransportCostsMatrix.Builder.newInstance(true);

calculateAndAddCosts(matrixBuilder, hopper, serviceStart.getStartLocation(), service1.getLocation(), “0”, “1”);
calculateAndAddCosts(matrixBuilder, hopper, serviceStart.getStartLocation(), service2.getLocation(), “0”, “2”);

    calculateAndAddCosts(matrixBuilder, hopper, service2.getLocation(), serviceStart.getStartLocation(), "2", "0");
    calculateAndAddCosts(matrixBuilder, hopper, service3.getLocation(), serviceStart.getStartLocation(), "3", "0");

    VehicleRoutingTransportCosts matrix = matrixBuilder.build();

    VehicleRoutingProblem.Builder problem = VehicleRoutingProblem.Builder.newInstance();

           problem.setRoutingCost(matrix)
                   .addVehicle(serviceStart)
            .addJob(service1)
            .addJob(service2)
            .addJob(service3);

    VehicleRoutingProblem problem1 = problem.build();

    VehicleRoutingAlgorithm algorithm = new SchrimpfFactory().createAlgorithm(problem1);

    Collection<VehicleRoutingProblemSolution> solutions = algorithm.searchSolutions();

    VehicleRoutingProblemSolution bestSolution = Solutions.bestOf(solutions);

    SolutionPrinter.print(problem1, bestSolution, SolutionPrinter.Print.VERBOSE);
    System.out.println("Optimized points:");
    bestSolution.getRoutes().forEach(route -> route.getActivities().forEach(activity -> {
        System.out.println("Lat: " + activity.getLocation().getCoordinate().getX()
                + " Lon: " + activity.getLocation().getCoordinate().getY());
    }));
    hopper.close();
}

private static void calculateAndAddCosts(VehicleRoutingTransportCostsMatrix.Builder matrixBuilder,
GraphHopper hopper, Location from, Location to, String fromId, String toId) {
double fromLat = from.getCoordinate().getX();
double fromLon = from.getCoordinate().getY();
double toLat = to.getCoordinate().getX();
double toLon = to.getCoordinate().getY();

    GHRequest request = new GHRequest(fromLat, fromLon, toLat, toLon).setProfile("car");
    GHResponse response = hopper.route(request);

    if (response.hasErrors()) {
        System.err.println("Ошибка при расчете маршрута: " + response.getErrors());
    } else {
        double distance = response.getBest().getDistance(); // Расстояние в метрах
        double time = response.getBest().getTime() / 1000.0; // Время в секундах
        matrixBuilder.addTransportDistance(fromId, toId, distance);
        matrixBuilder.addTransportTime(fromId, toId, time);
    }

I’m not entirely sure if this is the problem, but be aware that typically the ‘lat’ value corresponds to the Y(!) coordinate and the ‘lon’ value to the X(!) coordinate.
