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
