[sumo-user] cannot generate right traffic flow output through flowrouter

[kathy <k.li@xxxxxxxx>]

Dear SUMO-community,

I am working on generating a simulation with vehicle flow data in sumo.The
area is a region of a city, and the flow data of main streets in 24h are
given. The road network of this area I have exported from Openstreetmap and
converted to SUMO net file. From the observation data I defined about one
hundred detectors and their flows in detectors.xml and flows.txt, it
includes 7 source detectors and 8 sink detectors. The running of
flowrouter.py has no problem, and I can also run the simulation in SUMO-GUI,
but it seems that the traffic flow is not right, I run the flowFromRoutes.py
to compare the output flow with the input flow, it shows :
det_003;176.0;176.0;0.0
det_003_opp;170.0;170.0;0.0
det_004;36.0;36.0;0.0
#;avgRouteFlow;avgDetFlow;avgDev;RMSE;RMSPE;GEH;GEH%
#;127.33333333333333;127.33333333333333;0.0;0.0;0.0;0.0;100.0

and this is the result of running flowrouter.py:
Reading net
4583 edges read
Reading detectors
Loaded 7 sources and 8 sinks from detector file. Added 0 sources and 0 sinks
from the network
Reading flows
Calculating routes
7 sources, 7 unlimited
8 sinks, 7 unlimited
Writing 248 vehicles from 3 sources between time 0 and 3600
  unused sources: -161678034#0 27920078#0 32923867#0 64464430

I tried to delete the type definition in detectors.xml and use
--revalidate-detectors, the result changed a little bit, but still like
this, very few routes and flows are generted out, and the output flow is too
much different as the input. I uploaded the files and one diagram for the
detectors. Could anyone help me to get through this please? Many thanksin
advance!
