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

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

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!

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
