Re: [sumo-user] Use predefined routes in route distribution
Thank you. Then something like this should work (to not have 'route' as an attribute and an element):
<routes> <route id="route0" color="1,1,0" edges="beg middle end rend"/> <vehicle id="0" depart="0" color="1,0,0">
<routeDistribution>
<route refId="route0" /> probability="1" />
</routeDistribution>
</vehicle>
</routes>

Thank you a lot Jakob,

Would this route file also work (this would enable not using route as an element and an attribute of vehicle):
<routes> <route id="route0" color="1,1,0" edges="beg middle end rend"/> <vehicle id="0" depart="0" color="1,0,0">
<route refId="route0" />
</vehicle>
</routes>

You can define routes either with an id and reference them in your vehicle or as a child element of the vehicle.
Likewise you can define routeDistributions with an id and reference them in your vehicle (also with the route attribute) or as a child element of the vehicle.
Note, that not all of these variants are mentioned in the documentation but they are working and part of our nightly tests (https://github.com/eclipse/sumo/tree/master/tests/sumo/spec/distribution)

However, the format proposed in your first question had an issue that I missed on first reading
To reference an already defined route within a routeDistribution the attribute 'refId' must be used:
  <route id="route_0" edges="beg middle end rend" />
   <route id="route_1" edges="beg middle2 end rend" />
  <routeDistribution>
        <route refId="route_0" probability="0.1" />
        <route refId="route_1" probability="0.9" />
      </routeDistribution>

Jakob

Maybe this xml format would be more correct:
"" <routes>
   <route id="route_0" edges="beg middle end rend" />
   <route id="route_1" edges="beg middle2 end rend" />
   <vehicle id="0" type="type1" depart="0">
      <routeDistribution>
        <route route="route_0" probability="0.1" />
        <route route="route_1" probability="0.9" />

work (as Jakob mentioned)?

Restating my question: can I use route distribution using routes that have been already defined in the route file?

In other works, is there a route attribute in the route element to not have to redefine the edges attribute used by the route element everytime I would like to assign a different probability attribute to the given route element?

Thank you a lot for your help!

Hi,

 

no, it is not the same. Your second option is not right. If you already defined a route, then you only need to add the “route” attribute to your vehicle element.

<routes>

    <route id="route0" color="1,1,0" edges="beg middle end rend"/>

    <vehicle id="0" route="route0" depart="0" color="1,0,0"/>

</routes>

 

Your second example would be possible, if you are defining a new route as a child of your vehicle, like this:

<routes>

    <vehicle id="0" depart="0" color="1,0,0">

       <route edges="beg middle end rend"/>

    </vehicle>

</routes>

 

See https://sumo.dlr.de/docs/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#vehicles_and_routes

 

With routeDistribution, the definition of the routes according to the docu would be:

 

<routes>

    <routeDistribution id="routedist1">

         <route id="route_0" edges="beg middle end rend" probability="0.1" />

         <route id="route_1" edges="beg middle2 end rend" probability="0.9" />

    </routeDistribution>

    <vehicle id="0" depart="0" route="routedist1"/>

</routes>

Giuliana

Thank you Giuliana,

However https://sumo.dlr.de/docs/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#route_distributions is a little bit different as the routes in the route distributions in the example is not predefined outside the route distribution itself (i.e. the routes contain the attribute edges).

 

If I can do what I have suggested, then I guess that the two following route files will be understand the same way:

<routes>

    <route id="route0" color="1,1,0" edges="beg middle end rend"/>

    <vehicle id="0" route="route0" depart="0" color="1,0,0"/>

</routes>

 

end

 

<routes>

    <route id="route0" color="1,1,0" edges="beg middle end rend"/>

    <vehicle id="0" depart="0" color="1,0,0">

       <route id="route0" />

    </vehicle>

</routes>

 

Is this correct?

 

Thank you a lot!

Hi Theo,

 

Yes it is possible, see https://sumo.dlr.de/docs/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#route_distributions.

Betreff: [sumo-user] Use predefined routes in route distribution

 

Hi,

I would like to use route distribution using routes that have been already defined in the route file. Is this possible?
I was thinking about writting something like:
 <routes>
   <route id="route_0" edges="beg middle end rend" />
   <route id="route_1" edges="beg middle2 end rend" />
   <vehicle id="0" type="type1" depart="0">
      <routeDistribution>
        <route id="route_0" probability="0.1" />
        <route id="route_1" probability="0.9" />
      </routeDistribution>
</routes>
Would that work?

Thank you a lot!
Theo
