I executed the Veins example with the erlangen map and I put node[*0].veinsmobility.accidentCount = 0, I noticed, during simulation, that there was no exchange of messages between nodes which is logical.
I have generated my .rou.xml, .poly.xml and .net.xml files from SUMO and then I imported the new map in Veins. When I put accidentCount = 0 in the omnetpp.ini file, I noticed that there was exchange of messages between nodes. I want to know which these messages mean please?
