Re: [sumo-user] Vehicle rate per second
Thanks Jakob!
Regarding to your second point, how would you get those values from the last step?
Is there a method in TraCI? or TraaS?

Best regards,
José

- at runtime you can only retrieve the un-aggregated value for the last step. You will have to perform aggregation yourself.
- an alternative would be to implement a novel switching algorithm within sumo. However, this is more difficult and the main advantage would be execution speed for large scenarios.

Hi Jakob,

When you say "E2 detectors can be coupled to the switching of the traffic light." does this means that the aggregation is made by the traffic phase at each cycle?
What is the option for this?
On the same question, is it possible to retrieve that value in run-time during the simulation?
I want to take actions on this number that is changing at every step of the simulation.
One idea I had was to retrieve this data at each phase, or for the trafficlights to retrieve it and process it, for the edges that is controlling.

Best regards,
José

If the desired direction has a dedicate turning lane you can use any of the detectors or even laneData output.
Otherwise you have to use an E3 detector that covers the relevant incoming and outgoing lane.
All these options allow aggregation by a configuragable interval.
E2 detectors can be coupled to the switching of the traffic light.

Hi Jakob,

Regarding to retrieving the vehicle rate per unit of time(second, minutes) passing through a junction in a certain direction, what would be the best approach, if I need to retrieve it in run time every X unit of time, or under certain event.

Best regards,
José

If you want to separate the directions you can also use E3 detectors but you have to define them manually rather than with the linked scripts.

Another very basic approach is
  grep -c "edge1 edge2"' vehroutes.xml
To count the total number of vehicles taking a particular turn from edge1 to edge2

Jakob

Dear all,

How can I get the vehicle rate per second passing trough a Traffic Light.
And how can I get the number of vehicles going taking different directions in that junction?

Best regards,
José
