Re: [sumo-user] How to calculate the Vehicle Number and waiting duration at red phsae of Traffic lights

Using traci, you have to monitor the traffic light state continuously to determine phase duration.
Using the aforementioned XML outputs may be easier since they automate this.

Thanks, Jakob, how could  I know the red phase duration if the traffic type is actuated one?

Yes. You can use traci to check the number of vehicles that are waiting in front of a red light. Depending on your network, you may have to search along multiple lanes until you have covered the relevant distance (e.g. queue length).

2) for historical reasons the summary output refers to vehicles that are waiting for insertion (due to lack of road space) as "waiting". Vehicles that are slowed to a halt are counted as "halting"

Dear all,
I want to get the waiting number  and waiting time of vehicles at intersections (junction) when traffic lights at red phase. What's the best way for me to do that? 
If my simulation time is 10800s (3hours), and the traffic lights are actuated ones. How could I know the waiting number and the red phase duration in each circle of traffic lights??


More question, what's the  difference between the meaning of "halting" and the meaning of "waiting"?



Any kind response would be appreciated!

Best regards!

Jane
