Re: [sumo-user] Arbitrary departure time for vehicles controlled via Tra

[Jiachen Yang <jiachen_yang@xxxxxxxxxxxx>]

Hi Jacob,

From line 1202 in _vehicle.py, the add() method multiplies the input by 1000, so it seems that it receives input in seconds. If I use depart=1000, I observe that the car enters at 1000s in simulation time.

Thank you,

Jiachen

Hello,

method traci.vehicle.add expects time in milliseconds.

regards,

Jakob

Hi SUMO developers and users,


I'm trying to set arbitrary departure times for multiple vehicles that I'm controlling via TraCI. For example:


traci.vehicle.add( vehID='car_1', depart=2, ... )

traci.vehicle.add( vehID='car_2', depart=2.5, ... )


where car_1 and car_2 are on the same edge and lane. I observe that car_1 is able to depart at the correct time, but car_2 is delayed by more than 2.5 seconds. My guess is that there is some minimum distance requirement, which prevents car_2 from being emitted too closely after car_1. However, setting "minGap=0" in the vType definition does not help. Does anyone have suggestions?


Thank you,

Jiachen
