[sumo-user] Does the command "traci.vehicle.getContextSubscriptionResult

["Chason" <chenxiang_chason@xxxxxxxx>]

Hello:

I tried to get all vehicles' information in my simulation through "traci.vehicle.getContextSubscriptionResults()" command, but things didn't go well.

When the traffic number is large, the subscription command always returns fewer vehicles than the actual number running in sumo-gui.

My codes like that:

"

traci.vehicle.subscribeContext('ego', traci.constants.CMD_GET_VEHICLE_VARIABLE, 900000, [traci.constants.VAR_POSITION], 0, 2147483647)

...

sumo_vehicles = traci.vehicle.getContextSubscriptionResults('ego')

"

I also tried "traci.junction.getContextSubscriptionResults()", but the result is same.

Please help me to solve this problem.

Many thanks.
