[sumo-user] Can not figure out how to get some statistics

[". Abdullah" <ab11@xxxxxxxxxxx>]

Hi,

I was planning to find some statistics but can't figure out how to do it. 

1. How many times a car has stopped at intersections, that is if a car passes through 4 junctions but only stops at 2 red lights then I want to know that. I know getStopState returns (1 * stopped + 2 * parking + 4 * personTriggered + 8 * containerTriggered + 16 * isBusStop + 32 * isContainerStop) but I don't think I need all of these. 

2. How many cars have passed through a junction/intersection? I couldn't find any function in : https://sumo.dlr.de/pydoc/traci._junction.html#JunctionDomain-getIDList that can help

3. Finally, is there a way to find out how many cars are waiting at a junction based on direction? Let's say if we have a 4-way intersection and I want to find out how many cars are waiting at the north traffic light. I tried to use getLastStepVehicleNumber on an edge but I think that returns all cars present on that edge rather than just cars present at the intersection.

Sorry for so many questions, I am just stuck and need a little advice. Thanks in advance.
