Simulation of newly added example "7_platooning"

[bargisou]

Why is it that the simulation is only shown in the OMNET++ but no message transfer in OMNeT++ and only the net file is generated showing routes and edges but no vehicles running for the entire simulation.

[bargisou]

Is there any way to solve the below mentioned problem?

[ManiAm]

That is a generic problem. You need to check the Eclipse IDE console output to understand what is going on.

[ManiAm]

I have added the 7_platooning scenario to show the example in section '3.7 Adding Vehicle Platoon' of the manual.

[ManiAm]

Probably the addNode.xml file is empty. and the simulation terminates at time 0s, because there is no nodes in the simulation. Follow the manual ...

[bargisou]

Actually I have added a "add_0" node and made changes in the edge,node and route files accordingly.

[ManiAm]

The configuration should look like this:

include ../omnetpp_general.ini
[Config tutorial1]
description = "This config shows you how to add nodes into simulation"
Network.TraCI.active = true
Network.TraCI.SUMOapplication = "sumo-guiD"
Network.TraCI.SUMOconfig = "07_platooning/example.sumocfg"
Network.TraCI.terminateTime = 600s
Network.addNode.id = "add_0"

And the addNode.xml can have this content:

<?xml version="1.0" encoding="UTF-8"?>

<addNode id="add_0">
<vehicle_platoon id="plt1" type="passenger" size="5" route="route0" depart="0" departLane="1" departPos="40" platoonMaxSpeed="20" color="red" />
</addNode>

[bargisou]

Yes.It is the same

[bargisou]

The error still persists .But the files seem to be the same as you mentioned above.

[bargisou]

The console window says the following: <!> std::runtime_error: cannot open file addNode.xml -- in module (VENTOS::TraCI_Start) Network.TraCI (id=2), during network initialization Is there any command to simulate the addnode.xml file? Are we supposed to change tutorial.cc according to section 8 or section 9?

[ManiAm]

The error message is strange! VENTOS cannot find the addNode.xml file! Can you run your simulation in debug mode and tell me the line that throws this run-time error?

P.S: In the edge file, you created a 1 lane street, but in the addNode file you want to insert the platoon in lane 1? I think lanes starts with 0 index.

[bargisou]

Even if I change the depart lane to 0 index as you said the error still persists which says "SIMULATION ENDED AT TIME 0 & TCPIP Socket error" and in the console window "Cannot open file addnode.xml"

[bargisou]

I am not able to run the simulation in debug mode.

[bargisou]

Does the addnode.xml file need to be compiled when changes are made using command line before run configuration?

[bargisou]

Is there any way out through this to find out where exactly the problem lies?

[ManiAm]

Unfortunately I do not have any more hints for you!

The last option is to send your example as a file to me and I would have a look at it later on. Also send me an screenshot of your run configuration in eclipse.

The required files are attached below:

Can I merge and leave different platoon
