Hi Fereshte,
as you may have noticed already, this error is closely related to the
projection. It originates from an external library (PROJ) we use in SUMO
for this purpose. I don't know what is going on here. Does projection
inside SUMO work in other conditions on your device (e.g. reproject a
network with netconvert)? Could you maybe try yourself some other
projections to see whether it is related to the chosen projection
definition?
Best regards
Mirko

Unfortunately, I still could not reach the detectors additional file

Dear Fereshte,
I updated the example in the documentation. The numbers you mentioned are
not used and thus have been removed. I can imagine it was meant as a
search radius which finally was not implemented. Do you have your system
configured to invoke python automatically when typing a python file name
in the console? Otherwise prepend "python" to the command.

Dear Mirko,
I installed the required module following your instructions but my
problem is not solved yet!
When I run the command it does not give me neither error nor output.
Just the "mapDetectors" python file opens up!
The command is:
mapDetectors.py -n "D:\Users\Fereshteh.V6\UK\Traffic
Network\road.network.of.the.NorthEast\mySUMOnetwork.net.xml" -d
"D:\Users\Fereshteh.V6\UK\Traffic counts\Detectors.csv" -o
"D:\Users\Fereshteh.V6\UK\Traffic counts\Detectors.add.xml"
Any ideas?
Another question is about the example of this matter located at
SUMO_HOME/tools/detector/mapDetectors.py. What are the last numbers
(1000, 500)? Are they the number of vehicles that drove over the
detector? What if I want to give the number of passenger and transport
vehicles separately? How should I name them?

Hi Fereshte,
this is a separate python module you have to install. You can make
use of our $SUMO_HOME/tools/requirements.txt file together with pip
utility to get the right version (and other modules needed in python
tools shipped with SUMO). Usage / installation is explained here
<https://docs.python.org/3/installing/index.html> on the official
Python web site.

Dear Fereshte,
Sorry for the bit short-sighted answer last time. A projParameter
value of "!" actually means there is no projection defined. In
order to map detectors with a geographic coordinate one has to know
the target projection, too. Our MATSim importer doesn't read their
projection info yet.
What happens if you change the projParameter to "+proj=tmerc
+lat_0=49 +lon_0=-2 +k=0.9996012717 +x_0=400000 +y_0=-100000
+ellps=airy +nadgrids=OSTN15_NTv2_OSGBtoETRS.gsb +units=m +no_defs
+type=crs" (which corresponds to the EPSG:27700 value from your
MATSim file)?

Dear Mirko,
Now my network file contains a location tag and a projParameter

Dear Fereshte,
the file is very large and as such not easy to share. Probably it
is enough to place the right location tag in it. Mine looks like
this:

Dear Mirko,
Thanks for your response.
I would be thankful if you could share the converted network
including the location tag with projParameter attribute with me.
Then I will see if the script located at
SUMO_HOME/tools/detector/mapDetectors.py works with this network
or not.

did you use the latest SUMO version 1.18.0 or an older one?
If you used an older one, could you please check if the
projParameter attribute is still missing when converting
the MATSim network to SUMO in v. 1.18.0? And if you already
use the latest version, could you provide the MATsim file
together with the netconvert command to let us check?

Dear Mirko,
Thanks for your reply.
Actually, my network was edited by Matsim first but then I
converted it to a SUMO network using the "netconvert"
command.
Yes, there is a "location" tag in my network file. Please
see the image below. But it does not contain the "
projParameter" attribute.

This looks like your network file does not contain a

* Is there a location tag?
* Does it contain a projParameter attribute?
* If not, how did you create the network? Did you
edit it outside of netedit/netconvert?

My network is a very large network with a high number
of detectors. Is it possible to obtain the lane and
position of all detectors at once instead of one by
one?

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.
