[sumo-user] Problem with TraCI in SUMO 1.6.0

["Schrab, Karl" <karl.schrab@xxxxxxxxxxxxxxxxxxx>]

Hi all,

 

We are currently facing problems with TraCI in SUMO 1.6.0. We are using our own Java client to add vehicles, perform simulation steps, and catch subscriptions via TraCI. With the current version of SUMO, the command to add a vehicle (0x80, 0x85 as well) are executed successfully (no error message is logged or returned), however, no vehicle appears in the simulation. Executing simulation steps and retrieving subscriptions for the just added vehicle returns invalid values for all subscribed parameters (-2^30). Again no error log or message that the vehicle is missing, but only those invalid values. In the GUI the vehicle seems to be in the state “loaded”, but it is not displayed or simulated at all. With previous versions, e.g. 1.5.0 or 1.4.0, everything works fine. Has there anything changed in the way to interact/initialize with the simulation using TraCI?

 

Kind regards,

Karl
