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 <https://sumo.dlr.de/docs/Tools/Sumolib.html> , reference
<https://sumo.dlr.de/pydoc/sumolib.net.html> )
o load the network
o read your detector coordinates from input
o 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
o write the detector additional

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.
