Hello,
duarouter with a route or trip file as input will behave in a deterministic
fashion. However, when giving an alternative file ('rou.alt.xml") file as
input, duarouter will select an alternative route for vehicles
stochastically (this is also where the attributes las, cost and probability
are used). This type of usage is done repeatedly by the script
tools/routes/duaIterate.py when computing the dynamic user equilibrium.
(see http://sumo-sim.org/wiki/Demand/Dynamic_User_Assignment)
