The core of the simulation functionality which orchestrates the workflow of the simulation is fully implemented in DIVAs. The implementation of the “TrafficSimulation” class creates a “TrafficEnvironment” and binds it to the “TrafficSimulation”.

Implementation Steps

1. Inside the package “edu.utdallas.mavs.traffic.simulation.sim” create a class named “TrafficSimulation” that extends the abstract class “Simulation” defined in the package “edu.utdallas.mavs.divas.core.sim”.
2. The “TrafficSimulation” provides concrete implementations for the following abstract methods:
   1. “createEnvironment”: This method is responsible for creating the “TrafficEnvironment” at the simulation initialization and associating it to the “TrafficSimulation”.
   2. “tick”: This method is responsible for triggering the start of the simulation cycle. The full implementation of the class “TrafficSimulation” is provided in the following code.

   
package edu.utdallas.mavs.traffic.simulation.sim;

import java.io.Serializable;

import edu.utdallas.mavs.divas.core.msg.TickMsg;
import edu.utdallas.mavs.divas.core.sim.Simulation;
import edu.utdallas.mavs.divas.mts.MTSClient;
import edu.utdallas.mavs.traffic.simulation.sim.env.TrafficEnvironment;

    public TrafficSimulation(MTSClient client)
    {
        super(client);
    }

    @Override

    {
        environment = new TrafficEnvironment(client);
    }

    }
