Re: [sumo-user] [SPAM] duaiterate.py problems

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

at least we're getting something out of the discussion:

1) Yes.

2) You are correct in your assessment that duaIterate in it's current form is not suited for computing a user assignment together with dynamic road closures.

In the past we always used dynamic closures together with routing within the simulation (https://sumo.dlr.de/docs/Demand/Automatic_Routing.html) and I didn't fully grasp the problem earlier.

There aren't currently any plans to make duarouter understand rerouters (closing stuff). As a workaround you could model the closures with a variable speed sign that sets the speed to 0.01 on the lanes that should be closed instead of using rerouters. The reduced speeds in the simulation will be fed back into duarouter and vehicles will then avoid the slow parts of the network in the next iteration.

regards,

Jakob

Hi Jakob,

Thanks for your patience and kind responses. I am so sorry for this long
chain of emails but I have two more questions:

1) I moved those options to the last of the list and now I think that I
should update my sumo version because of this message
"--time-to-teleport.disconnected" is not a valid option for "C:\Program
Files (x86)\Eclipse\sumo-git\bin\sumo"

My sumo version is 1-7-0 while the option --time-to-teleport.disconnect
started to support value 0 for teleporting without waiting from version
1-9-1. Am I right?

2) According to what you said before (duaIterate runs both duarouter and
sumo on your inputs.
However, only sumo supports loading closingReroute and closingLaneReroute.
Such definitions will be ignored when passed to duarouter with option
duarouter--additional-files) and using these two options
("sumo--ignore-route-errors"  and "sumo--time-to-teleport.disconnected 0"),
duaIterate assigns the traffic to the network without considering the closed
links and then in the next step (traffic simulation) those trips which
include closed links in their routes will be easily ignored and considered
as cancelled trips. Please correct me if I am wrong. Otherwise, I believe
duaIterate is very far from reality and could not be used in case of some
links closures.

Many thanks,
Fereshteh
