Re: [sumo-user] Flow Edge data

Good afternoon!

Thank you!

Regarding the tool: instantOutToEdgeCounts.py, what was my mistake in using it?

In a new version of SUMO, is it possible to include the timeLoss/veic output in the edge data?

Regards,

Pedro Oliveira

Thank you very much for your careful observation and the examples. It was indeed a bug in the flow computation which is now fixed in the development version:

Good morning!

Attached file.

https://we.tl/t-Wh48CM66YT

I managed to run the command: instantOutToEdgeCounts.py, I included the following parameters:
"%SUMO_HOME%/tools/output/instantOutToEdgeCounts.py" -d contadors.add.xml -i result_cont.xml -o detector_data.xml -b 0 -e 3600

However, the file remained empty.

Indeed, in my own simulations, the 'flow' attribute is always lower than the 'intermediate' value and this is what I would expect due to discounting of partial distances on departure and arrival.
Please provide a minimal example simulation where the flow is higher.

PS: the new tool is called in instantOutToEdgeCounts.py and resides in tools/output (the name given in the changelog was wrong and has now been corrected).

Good evening!

I'm analyzing the "flow" output data that was added to "Edge data".

I installed version 1.25 with all the extras to run the new tool: instantOutToEdgeData.py, but the command was invalid (not recognized). I couldn't find the new command in the SUMO folder.

For a more realistic comparison, I would like to present a comparison of the flows from our detectors, but since I couldn't run the new tool, I'm presenting the comparison from the CountEdgeUsage tool (the detectors showed lower values).

The following figures show the comparison between countedgeusage and the flow output (edge data) from the new version of SUMO. I expected to see that flow would always be less than or equal to the count of the edges/detectors. I would like to understand the values that are higher.

Thank you in advance for your attention.
