ms-van3t usage issue

[jamesrenxiangyu]

Thanks so much for developing & sharing this amazing ns3-v2x platform. It helped me a lot for my research on vehicular networks.
While I was exploring ms-van3t, I hoped to measure the traffic flow of a particular vehicle (e.g., how many packets it has received during the simulation time). I wonder if this function has been implemented in ms-van3t or not. If yes, could you please give me some insights on how to obtain these trace files? Thanks so much!
