Re: [sumo-user] Possible issue in closingLaneReroute
Hello,
while this behavior is admittedly not intuitive, it is intended. ClosingLaneReroute and closingEdgeReroute are meant for different purposes. The former is meant to allow some vehicles of the fleet to react to potential slow-downs from closed lanes. Detecting the special case "all-lanes-are-closed" and handling it like a closingEdgeReroute would potentially carry a performance penalty during the simulation.
You can get the desired behavior if you equip all vehicles with a reroutingDevice (--device.rerouting.probability 1).
regards,
Jakob

Good afternoon,

 

I’ve trying out the Rerouter (https://sumo.dlr.de/docs/Simulation/Rerouter.html) in SUMO to close a large number of lanes simultaneously within the network for a given period of time. I have then placed rerouters prior to these closures to trigger the vehicles to reroute accordingly. When I have tried the closingLaneReroute method however the vehicles do not reroute. For comparison I’ve tried closing the edges instead of the lanes and in this instance vehicles do reroute. I’ve included an example of my input data below:

 

 

For both scenarios in my additional file I have multiple lines with the following format:

 

<rerouter edges="177728541 177728531" file="R_Zone97.shp.def.xml" id="Zone97.shp" probability="1" />

 

 

Ideally I want to be able to close individual lanes with some edges having all lanes closed. In the lookup file I would have the following when attempting to close lanes:

 

<rerouter id="Zone97.shp">

                <interval begin="25200" end="27000">

                                <closingLaneReroute disallow="all" id="177728531_0" />

<closingLaneReroute disallow="all" id="177728531_1" />

                </interval>

</rerouter>

 

When I run the simulations with the lane closure lookup files none of the vehicles actually reroute.

 

For comparison, instead of closing lanes I tested closing edges and amending the lookup files accordingly:

 

<rerouter id="Zone97.shp">

                <interval begin="25200" end="27000">

                                <closingReroute disallow="all" id="177728531" />

                </interval>

</rerouter>

 

 

When I run the simulation in this instance in my output tripinfo.xml file I now see that vehicles are rerouting.

 

I’m wondering, could there be a bug in the rerouting algorithm when using rerouters which is causing sumo to ignore the rerouters for lane closures even if the all lanes are closed which would be similar to closing an edge?

 

Any insight would be greatly appreciated.

 

Kind regards,

 

Barry
