  • Thread-topic: Default of departLane

Dear SUMO team,

 

I am wondering if it would be better to set the default of departLane to “best” instead of “first” for microsimulation.

In a multi-lane condition, if the default is “first”, this means that the maximum flow at the entry can never actually exceed the capacity of one lane. At least this is what I’ve observed. Could you confirm this?

It is going to cause trouble when expecting the inflow demand to be larger than the capacity of one-lane. For OD calibration, this can be problematic.

 

Thanks in advance for answering.

 

Kind regards,

Ying-Chuan Ni
