[sumo-user] cannot get right routes file from dfrouter

[kathy <k.li@xxxxxxxx>]

Dear SUMO-community,

I am working on how to generate a simulation with vehicle flow data in sumo.
The area is a region of a city in Germany, 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. I thought it could be
simulated through DFROUTER, but I cannot get through. I have already run
through the dfrouter example in "Sumo\doc\examples\dfrouter", it works. What
I have done is:
1. define detectors and flow as the example does
2. write a dfrouter cfg file to generate route file and emitter file
3. run the sumo-gui 
The simulation ends at time 0.00, so I checked the emitter file and found
the vehicles don't exist. And during dfrouter runs, a lot of errors poped
out showing "Waring: could not close routes for *"(* means detecor id)", it
was very slow but at end it can success. Then I tried to:
1.narrow down the size of the network and reduce the number of detectors to
simplify the problem, to simulate as much as possible to the dfrouter
example.
2.modify the parameters in flow file definition, flow data of streets,
quantity of PKW, velocity etc.
3.add -detector-output in dfrouter.
4.add detector Type in definition
>From detector output I found most of the detectors that I defined were
discarded. It still didn't work and poped out warning like before. I
uploaded the files and one diagram for the detectors. Could anyone help me
to get through this please?  Sumo_dfrouter_Kathy.7z
