[sumo-user] Vehicles aware of other vehicles?

["Martinez, Hector A" <hmartinez@xxxxxxxxx>]

Good morning Sumo-users,

 

I would like to understand how vehicles are aware of other vehicles.  For example, how does a vehicle know that he needs to change lane because the vehicle in front is either too slow or it stopped.

 

What information does one vehicle know about the other and how can I retrieve that info using TraCI or TraaS?

 

Thanks,
