Set subtourModeChoice by subpopulation

[jademackay]

Hello, I would like to specify the mode choice behaviour for subpopulations . I have tried this in the config

    <module name="subtourModeChoice">
      <param name="behavior" value="fromAllModesToSpecifiedModes"/>
      <param name="chainBasedModes" value="car"/>
      <param name="considerCarAvailability" value="true"/>
      <param name="modes" value="bus,bike,walk,car,car_passenger"/>
      <!-- <!-\- <param name="modes" value="car"/> -\-> -->
      <parameterset type="subpopulation">
	<param name="subpopulation" value="regular"/>
	<param name="behavior" value="fromAllModesToSpecifiedModes"/>
	<param name="modes" value="car"/>
      </parameterset>
    </module>

however the subpopulation parameterset is ignored. Note that the desired effect is achieved globally if <param name="modes" value="car"/> is uncommented.

Thoughts and suggestions welcomed!

I take it that you want different subtourModeChoice behavior for different subpopulations. I fear that that is not possible, almost certainly not from xml, and possibly not even from Java (in a simple way).

However, from looking at your snippet, it looks like you do not want mode choice at all for one of your subpopulations. This should be possible, by configuring the subtourModeChoice strategy only for the one subpopulation but not for the other. (I think that the config module is now called the "replanning" module.)

Hi @kainagel , thanks for your response.

it looks like you do not want mode choice at all for one of your subpopulations.

I think it looks that way because I over simplified the snippet. I actually want to restrict the mode choice options for the subpopulation like this:

<module name="subtourModeChoice">
      <param name="behavior" value="fromAllModesToSpecifiedModes"/>
      <param name="chainBasedModes" value="car"/>
      <param name="considerCarAvailability" value="true"/>
      <param name="modes" value="bus,bike,walk,car,car_passenger"/>
      <!-- <!-\- <param name="modes" value="car"/> -\-> -->
      <parameterset type="subpopulation">
	<param name="subpopulation" value="regular"/>
	<param name="behavior" value="fromAllModesToSpecifiedModes"/>
	<param name="modes" value="bus,car"/>
      </parameterset>
    </module>

Do you think this might be possible by "configuring the subtourModeChoice strategy only for the one subpopulation but not for the other." ... this is precisely what the example is trying to specify??

... ah I think you mean only to provide the subtourModeChoice strategy for one subpopulation

I am considering making the modes prohibitively expensive for the subpopulation but restricting the subtourmodechoice set would be more direct and efficient.
