Hello,

In a paper, it is simulated a 4-leg traffic intersection and a traffic light on it. It is proposed a dynamic traffic light scheduling algorithm and it is considered the presence of emergency vehicles.

It is used SUMO simulator to generate several mobility scenarios and NS-2 to implement the proposed algorithm. In final, it is measured the throughput and delay of vehicles in the intersection when it used the scheduling algorithm.

I am a beginner in traffic simulation and SUMO and NS2. I studied the traci_tls example in SUMO docs tutorials (https://sumo.dlr.de/wiki/Tutorials/TraCI4Traffic_Lights) which used just SUMO to control the traffic light for the emergency vehicles crossing.

Now, why that paper used SUMO and NS2 together? May it control the traffic light in NS2?

Thank you
