Re: [sumo-user] Routes from counting data

Dear Mirko, dear Fereshteh,

there is a tool for that: https://sumo.dlr.de/docs/Tools/Detector.html#mapdetectorspy

You'll have to do this in a few steps:

• import your geo-referenced network
  
• convert your detector coordinates in Python using sumolib.net (see docs, reference)
  
  • load the network
    
  • read your detector coordinates from input
    
  • for each detector coordinate:
    
    • get point in XY space: sumolib.net.convertLonLat2XY
      
    • store obtained lane and position of the detector from sumolib.net.lane.getClosestLanePosAndDist
      
  • write the detector additional
    

Best regards

Hello!

 

I have a question regarding the detector file.

As it is mentioned in https://sumo.dlr.de/docs/Demand/Routes_from_Observation_Points.html, SUMO requires the position of the detector on the lane to be expressed in meters. Specifically, the position should fall within the range of -1*lane's length to the lane's length. What I have in my database of detectors is the "latitude" and "longitude" of detectors. I wanted to know whether SUMO can read the "latitude" and "longitude" of detectors and locate the detectors on the network or not. If yes, could you please guide me on how to insert this information in the detector file?

 

Thanks in advance.
