Re: [sumo-user] Simulation Duration

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

it's hard to tell from the given numbers how long the simulation should run because it also depends on the average time a vehicle spends in the network. (see https://sumo.dlr.de/docs/FAQ.html#how_fast_can_sumo_run).

However, when a simulation is running surprisingly long, this is often caused by unexpected jamming/deadlocks. I recommend writing summary output (option --summary-output).

While the simulation is still running you can use this output to detect jamming by looking at the number of vehicles that are present in the simulation, the average speeds and the number of halting vehicles.

The next step is then to observe the simulation visually and determine what is causing the jamming.

regards,

Jakob

Dear all,

My simulation is running for more than five hours and I would like to ask you if it is expected (due to large demand) or I have to do something to change it. I am refering to you some characteristics: 18,733 vehicles (warmup route file), 79,267 vehicles (main route file). Also, I have imported public transport. When I run randomtrips.py, I had defined as an attribute -p 0.032 for more vehicles. For calibration, I used routeSampler.py tool and then the attribute --optimize full.

Thank you for your time.

Fay
