I am attempting to simulate highway traffic in SUMO. I have a set of historical highway data measured using detectors. I have created a detector file and measure files using data from the highway that I would like to simulate. Using dfrouter, I created an emitter file, routes file, and validation file. The routes file contains the desired routes and the emitter file contains approximately the desired amount of vehicles at the desired departure speeds. But when I generate an FCD file, the simulated speeds do not match my measured speeds. I am trying to simulate dense traffic with speeds at ~4.5 m/s, but the simulated speeds are around 25m/s.
The only step that does not make sense to me is when I generate the FCD file. I don't see how the speeds could match the measured data because the measured data is not an input at that step. It is only an input to dfrouter when the emitter file is created.
Below are the commands that I am using. Any ideas are appreciated!
dfrouter -n map.net.xml -d DetectorFile.xml
--measure-files MainlineFlows.txt,RampFlows.txt --routes-output Routes_Output.xml --emitters-output Emitters_Output.xml --validation-output
Validation_Output.xml --detector-output Detector_Output.xml -v true --time-step 300
-Just a note here, the ramp data does not have speeds so I had to create two files for measured data.
sumo -n map.net.xml --additional-files Routes_Output.xm
