Implementing a Unified Vehicle Manager Class in Mosaic

[yibork]

I am wondering if it is possible to have a single vehicle class that manages other vehicles. In other words, in Mosaic Mapping, I would declare the vehicle manager as a Vehicle which is a java application, and this manager would create different vehicles, assign positions to them, and also be responsible for controlling them.

Hey @yibork,
without putting too much detail into it, I think it is possible to send VehicleRegistrations from within your application.

            final VehicleRoute vehicleRoute;
            try {
                vehicleRoute = SimulationKernel.SimulationKernel.getCentralNavigationComponent().getRouting().createRouteForRTI(<YourCandidateRoute>);
            } catch (IllegalRouteException e) {
                throw new RuntimeException(e);
            }

            VehicleRouteRegistration routeRegistration = new VehicleRouteRegistration(
                    getOs().getSimulationTime(),
                    vehicleRoute
            );
            getOs().sendInteractionToRti(routeRegistration);

            VehicleRegistration vehicleRegistration = new VehicleRegistration(
                    getOs().getSimulationTime(),
                    UnitNameGenerator.nextVehicleName(),
                    null,
                    Lists.newArrayList(
                            <YourApp>.class.getCanonicalName()
                    ),
                    new VehicleDeparture.Builder(<Your.getId())
                            .departureLane(VehicleDeparture.LaneSelectionMode.FIRST, 0, 0)
                            .departureSpeed(VehicleDeparture.DepartureSpeedMode.MAXIMUM, 0)
                            .create(),
                    <YourVehicleType>
            );
            getOs().sendInteractionToRti(vehicleRegistration);

Furthermore, then you could control the vehicles either by using V2X-Messages or by directly using TraCI-commands using the respective API (see https://github.com/eclipse/mosaic/blob/main/app/tutorials/example-applications/src/main/java/org/eclipse/mosaic/app/tutorial/traci/SumoTraciInteractionApp.java and https://sumo.dlr.de/docs/TraCI/Change_Vehicle_State.html).

I hope this gives you an initial starting point. Feel free to ask ahead if further questions arise!
