Re: [sumo-user] Calibration Queue

Using 15 minutes traffic instead of hourly probably won't help very much unless you have very unusual traffic patterns (i.e. some 15m intervals with very low traffic).

However:

- straight-traffic could have different spacing (i.e. even spacing would make it harder to turn left compared to having dense platoons and longer gaps) even though the total count is the same in both cases.  If you are generating traffic with even spacing, switch it to poisson-distributed (https://sumo.dlr.de/docs/Simulation/Randomness.html#poisson_distribution)

- multiple parameters besides 'impatience' could be tuned to cause acceptance of shorter gaps (https://www.eclipse.org/lists/sumo-user/msg15120.html)

Good morning!

I'm analyzing a type of intersection where the SUMO results are far from what happens in practice; the queue of movement shown in red at the intersection is much longer in the simulation.

 

We are using impatience to improve the simulation, but it wasn't enough.

One solution I thought of was, instead of generating hourly traffic volume with data over 3600 seconds, to provide hourly volume in 4 intervals of 15 minutes, since we have fractional searches. Could this help?

Sds,

Pedro Oliveira
