Re: [sumo-user] selected route according to the marouter outputs

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

When starting the simulation, each vehicle will pick a random route from its routeDistribution according to the normalized probabilities. Running the simulation multiple times with different seeds (https://sumo.dlr.de/docs/Simulation/Randomness.html#random_number_generation_rng) will result in different picks.

regards,

Jakob

Hi,

I am simulating a road network using meso-simulation. For doing this, I
firstly used marouter command for assigning the routes to vehicles. the
output of marouter for each vehicle is like following:


<vehicle id="lig358775" depart="0.02" type="passenger" fromTaz="45689"
toTaz="45046" departLane="free" departSpeed="max">
        <routeDistribution>
            <route cost="119970.86" probability="0.00000000"

As it is shown in the subsection of routeDistribution, cost, probability and
edges of different routes for the vehicle are calculated. But finally, it is
not clear that what route will be assigned to this vehicle in the simulation
process, although running meso-simulation using this marouter's output file
works correctly without any error. Briefly, my question is: According to
this marouter output, how can I understand what route is assigned to this
vehicle? I guess the route with the lowest cost and highest probability will
be chosen for every vehicle in the simulation process but I want to be sure.

Thanks in advance for your response.

Sincerely,
Fereshteh
