Hi Jakob,
Thanks for your reply. I am trying to run the dfrouter examples provided by
SUMO source code to understand how to use dfrouter to generate needed outputs
as following:
dfrouter -n input_tri.net.xml -d input_tri.det.xml --measure-files
input_tri_flows.txt --routes-output routes.rou.xml --emitters-output
emitters.rou.xml --validation-output validation.xml
There are total 40 routes in emitters.rou.xml. However, in the
input_tri_flows.txt, there are total 40+10+10+..=180 cars at time = 0. When I
check the validation files, there are still many sensors with 0 values. Did I
make mistake somewhere?
Morover, the flow file that I provided miss some flow values at some time slot.
Will that still be allowed for dfrouter?
Thank you,
Best regards,
Tran

Check the total number of vehicles that were generated (in the output file of
option --emitters-output) against your expectations.
The warnings could indicate why not all of the desired routes (and thus
vehicles) have been generated. They are typical for networks that have
insufficient sink detectors declared.
See the options documented at
http://sumo.dlr.de/wiki/Demand/Routes_from_Observation_Points#Computing_Routes
for working around these warnings.

Hi All,
I figured it out that I can use the validation.xml as an additional file while
I run the simulation to generate validation_dets.xml. However, most of the
sensors have 0 counts, which is very different from the real information
(failed validation). When I use dfrouter, I still got a lot of warnings like
"Quitting checking for being a source for detector ... due to seen edge limit."
and "Could not close route for...". Did these warning cause the problems? And
how should I get rid of these warnings?
Thank you very much.
Best,
Tran

Hello All,
I performed dfrouter to import sensor information and want to validate the
simulation. I put detectors at those locations and retrieve the vehicle counts
and speed for validation but most of the sensors read 0. Could I do this for
validation? Is there anything wrong with this?
Moreover, I also saw that we can perform validation by --validation-output
validation.xml, but when I ran the simulation, I got an xml file with some
information like:
<e1Detector id="validation_10113" lane="-121939397#30_0" pos="104.24" freq="60"
friendlyPos="1" file="validation_dets.xml"/>
There is no validation_dets.xml created, and I do not how to use this file for
validation.
Could you please explain more clearly how I should validate my simulation using
dfrouter..
Thank you very much.
Best regards,
Tran
