How to get the detector information from the COM interface of VISSIM

Question

How can I get the state of the detector from the COM interface of VISSIM?

Answer 1

Detectors, or as Vissim calls it, Data Collection Measurements can be fetched from COM using the command:

Detector = Vissim.Net.DataCollectionMeasurements.ItemByKey(detector ID) 

Then you can check for the required values, if equipped using this command:

Speed = Detector.AttValue('Speed(Current,Avg,All)')

This will retrieve the current average speed for all the lanes.
