| Re: [sumo-user] Realistic Simulation with traffic data and calibration |
Thank you. I updated to version 1.5.0
I think I can generate a turn_count.xml based on my traffic count data from
the real world because I have the edge IDs in my network and count data for
the turns. I used the format
<interval id="generated" begin="0.0" end="99.0">
<edgeRelation from="-58.121.42" to="64" count="1"/>
<edgeRelation from="-58.121.42" to="-31" count="3"/>
<edgeRelation from="45" to="-68" count="3"/>
<edgeRelation from="-31.80.00" to="31" count="1"/>
<edgeRelation from="-31.80.00" to="37" count="1"/>
<edgeRelation from="-31.80.00" to="-23" count="13"/>
<edgeRelation from="-92.180.00" to="-60" count="1"/>
</interval>
filled in the edges (from NETEDIT) and the counts, called routeSampler via
command line:
"C:\Python27\python.exe" "C:\Program Files
(x86)\Eclipse\Sumo\tools\routeSampler.py" -r osm.net.xml -t turncount.xml -o
outputRouteSampler.xml
And got this error:
Traceback (most recent call last):
File "C:\Program Files (x86)\Eclipse\Sumo\tools\routeSampler.py", line
199, in <module>
main(get_options())
File "C:\Program Files (x86)\Eclipse\Sumo\tools\routeSampler.py", line
142, in main
countData = (parseTurnCounts(options.turnFile, routes, options.turnAttr)
File "C:\Program Files (x86)\Eclipse\Sumo\tools\routeSampler.py", line 94,
in parseTurnCounts
for fromEdge in interval.fromEdge:
TypeError: 'NoneType' object is not iterable
Can you please explain me what is causing the NoneType error and what I can
do about it?
