Re: [sumo-user] flowrouter.py module 'detector' has no attribute 'DetectorReader'
Hi Giuliana,

Thanks for your help, I tried with the ordered flow file, it worked.
And a few questions with the output files, after I use the command below,
flowrouter.py -n Tokyo.net.xml -d detectors.xml -f flow.txt -o out.add.xml -e out.rou.xml -v --vclass passenger --source-sink-output sourceSink.xml --revalidate-detectors  

the output is:
Reading net
748 edges read
Reading detectors
Warning! Edge '854532682' is simultaneously source and sink.
Loaded 0 sources and 0 sinks from detector file. Added 14 sources and 15 sinks from the network
Reading flows
Calculating routes
14 sources, 13 unlimited
15 sinks, 14 unlimited
Writing 3548548 vehicles from 9 sources between time 0 and 60 (minutes)
  unused sources: 437896359#0 45170906 648167166#0 667868686#0 759377422

1) 13 unlimited and 14 unlimited, what's the meaning of this?
2) The flow data I used is collected by every 5 minutes, and the time range is 0 minute to 1435minutes, 
but the results showed that only data of time range 0 ~ 60 （minutes) has been calucated.
I checked the out.rou.xml file, the definition of each flow is with time range 0~3600s, 1 hour.
<flow id="173954139_45018427.qPKW" departSpeed="max" departPos="last" departLane="best" route="173954139_45018427.qPKW" number="22869" begin="0" end="3600"/>
So, is there a limitation for the time range?   

For your reference, I attached with the refreshed zip file.
Thanks a lot.

Hi,

 

I think you just need to sort the flow file in ascending time. Attached I send you your file in order, try again with that file, I hope it works 😊

 

Regards,

Giuliana

Betreff: [sumo-user] flowrouter.py module 'detector' has no attribute 'DetectorReader'

 

Hi All,

I am working on how to simulate the traffic senario with real traffic data of Tokyo, which is downloaded from UTD 19 dataset.


I searched on the SUMO documentation, and tried DFROUTER first, but there's warning called: "could not close route for ~~~“

So I checked the SUMO user maillist and get a similar case.

 

Following the possible solution, I change to use flowrouter.py. Here is what  I have done.

flowrouter.py -n Tokyo.net.xml -d detectors.xml -f flow.txt -o out.add.xml -e out.rou.xml -v --vclass passenger --source-sink-output sourceSink.xml --revalidate-detectors

 

The output is:

Reading net
748 edges read
Reading detectors
Traceback (most recent call last):
  File "D:\Program Files (x86)\Eclipse\ST\flow\flowrouter.py", line 989, in <module>
    sources, sinks = reader.readDetectors(options.detfile)
  File "D:\Program Files (x86)\Eclipse\ST\flow\flowrouter.py", line 845, in readDetectors
    self._detReader = detector.DetectorReader(detFile, self._lane2edge)
AttributeError: module 'detector' has no attribute 'DetectorReader'


The SUMO version I used is the latest one: 1.8.0, winx64, 

my system is win10 1809, and Python version is also the latest one: 3.9.0

 

I also attached the files in the email. 

What maybe the possible reasons for that error? How to fix it?

Thanks for your help in advance!
