Re: [sumo-user] Reducing delay at priority right/left turns
Sanjay,
I had what sounds like a similar issue, and bumping the "impatience" parameter (https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#impatience) of the vType from 0.5 to 0.6 for most vehicles in the model made the network flow much more believably.  I can't say what the right value should be for you or how this might interact with your other parameters, but it made intuitive sense for the region of the US that I'm modeling where drivers are more likely to make risky turns and cut off oncoming traffic if they wait too long.

Hi,

We find that vehicles seem to wait an unrealistic amount of time while making a right or left turn from a lower priority to higher priority road. As a result, this results in large congestions and spill-back at intersections with slightly higher demand. Based on visualizing this in sumo-gui this amount of waiting doesn't seem realistic. What parameters can we use to reduce the delay of vehicles waiting to make such turns?

Thanks
Sanjay
