[sumo-user] mesoscopic highway simulation questions

[Chao Zhang <chaozhng@xxxxxxxxxx>]

Hi SUMO users,

I have two questions regarding mesoscopic simulations for highways in SUMO:

1. Highway traffic bottlenecks: My mesoscopic model with default queueing model parameters isn't showing expected congestions at merges, even with increased demand. I am adjusting the mu-queue model's tau parameters and other two parameters: jam threshold and minor penalty. Is this the correct approach? 

2. Priority at merge: Unlike microscopic models (e.g., 'priority', 'zipper' in junction type), the mesoscopic model lacks explicit merge priority controls. Since it solely relies on headways and penalties, have any of you implemented any mechanism for mesoscopic to handle pre-defined priorities? If so, how?

Any insights or advice would be greatly appreciated. Thanks!
