Re: [sumo-user] Traffic simulation for a month

[Jakob Erdmann]

The differences are up to you. By providing different route files for the
different days (i.e. less traffic on weekends) you have full control over
the variability. SUMO itself will not perform replanning based on past
experiences. Unless you have jams that are not resolved during the night,
each simulated day should be pretty much independent of the previous day
(though you will see different random numbers when running the simulation
for multiple days compared to running these days separately).

Re: [sumo-user] Traffic simulation for a month

[Tripplanner Mumbai]

Hello,
Yes, segregating the routes data as per suggestion will be helpful.
However, I am clueless about the underlying theory of simulation in SUMO.
That is, how it simulates each day differently (given the network file and
separate routes files). What are the attributes it takes into account to
imitate the real-time scenario?
Thanks and regards,
Dillip Rout

Re: [sumo-user] Traffic simulation for a month

[Michael Behrisch]

Hi,
it is entirely up to you how you organize the files. I would expect the
network to be quite stable so there is no need for several network
files. You can also put all routes in one file but if you need fast
access to a specific day or even hour or want to do parallel simulations
of different time periods you should split the route files according to
that requirement. But this is not enforced it is just optimization.

Best regards,
Michael

Re: [sumo-user] Traffic simulation for a month

[Tripplanner Mumbai]

Hello,
Let us assume that a machine with sufficient computing power is available.

Now, there are two bare minimum input files for the simulation (1)
city.net.xml - contains the structure of the underlying network  (2)
city.rou.xml - contains the vehicles and respective routes (paths) and
possibly schedule.

Do you mean that we should have separate files of (1) and (2) for each day
of the month?

thanks and regards,
Dillip Rout

Hi,
if you have the input data it only requires enough computing power (or
patience ;-). Nothing stops you from running sumo for a month or more.

Michael

[sumo-user] Traffic simulation for a month

[Tripplanner Mumbai]

Hello,

SUMO is pretty nice in simulating traffic and getting the relevant
parameters given a scenario including traffic and network. However, these
simulations are only for a short period of time or a day.
What more is required to simulate the traffic movement for a month? Note
that the traffic pattern differs from day to day, e.g., weekends will have
less traffic as compared to weekdays. Hence, we will get different kinds of
simulations on weekends. Mostly, I am looking to extract a network from OSM
through the interface provided by SUMO.

thanks and regards,
Dillip Rout
