Signalized intersection analysis in SUMO

[zhengli-hub]

I see that SUMO provides some built-in road capacity analysis capabilities here. However, I'm specifically interested in analyzing signalized intersections using Highway Capacity Manual (HCM) methodologies - particularly calculating metrics like saturation flow, delay, and intersection capacity according to HCM standards. Are there any existing scripts or tools in SUMO that can automatically perform these HCM-specific calculations?

By the way, is there a way to output the phase diagram of signal timing shown as follows in SUMO?

Currently we don't provide scripts which replicate exactly HCM standards. As you could note from the referenced doc page, the saturation flow is influenced by the car-following model settings. Delays are measured and can be queried using several of our output options.

For the second question: There is no tool for this yet neither, but sounds like an interesting idea.

For measuring the progression of headways at the stop line, instantInductLoop should be suitable: https://sumo.dlr.de/docs/Simulation/Output/Instantaneous_Induction_Loops_Detectors.html
