Re: [sumo-user] Running simulation and getting vehicle information indep

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

If you want to share a single traci connection between two threads you must handle the locking yourself.

Alternatively, you can connect two clients with seperate processes. See http://sumo.dlr.de/wiki/TraCI#SUMO_startup (--num-clients)

I have the following Traci Client program.

#include <iostream>

#include <stdlib.h>

#include <string>

#include "TraCIAPI.h"

class Client : public TraCIAPI {

public:

    Client() {};

    ~Client() {};

};

int main(int argc, char* argv[]) {

    Client client;

    int order = atoi(argv[1]);

    client.connect("localhost", 47000);

    std::cout << "run 5 steps ...\n";

    TraCIAPI::VehicleScope vehicleScope(client);

    while(true ) {

        client.simulationStep();

        libsumo::TraCIPosition pos = vehicleScope.getPosition(std::to_string(order));

        std::cout << pos.x << ", " << pos.y  << std::endl;

    }

    std::cout << "time in ms: " << client.simulation.getCurrentTime() << "\n";

    client.close();

}

Here in the while() loop I am advancing the simulation and getting vehicle information. My question is, is it possible to advance the simulation in one place (like in another thread) and get vehicle position in another place ?
