Issues with calibration. #33
Comments
Dear Lorena, I can't see an obvious problem with your setup (maybe someone else can). What is fairly obvious is that you have indeed by far not enough traffic. On the links where you have counts they are around 3600 veh/hr; at 5% you should have around 180/hr, and not the 0 to 6 you are getting (before multiplying with 20). I would for the time being forget about counts (and even iterations; set lastIteration=0) and try to find out where that missing traffic got lost. Things to check:
If you cannot get it plausible at this level, then the simulation will also not be plausible further downstream. It is also our experience that most of such problems are at this level. Please keep us posted ... PS: Note that the flow/storage factors (in your config file) are 0.2 und 0.3, without the "%". Corresponding to 5% they should rather be 0.05, but that should (at this point) not be the problem you are having. |
Dear, I visualized in the OTFVIS and VIA and what happens is that, at a given moment (peak hours like 06am), all the agents are stopped and remain this way suntil the end of the day. The network is very loaded and the agents stop to transit, I believe that this is why the count is so low. PS: I did what you’ve recomended about the flow/storage factors, thanks! Ps2: In the scenário base, i’m only simulating bus and car as main mode... so Walk needs to be teleported? Thanks in advance https://drive.google.com/drive/folders/1qUVTypRheWwolwyBwEZeXrkR2LxnkkH6 |
Dear Lorena, |
Dear @LorenaBR , I am facing the same problem. Did you solve the problem? |
Sorry for the delay, but the main problem was the geolocalization of my network and of my agent's plans, they weren't in the same coordenate. Once I fixed this, the calibration was possible. |
No, i didn't use the RunCadyts4CarExample.jav to run my scenario, because after i fixed my coordinates, it was possible to calibrate "manually" my simulation. |
Dear all,
When i runned my first scenário (Without calibrate with Cadyts),I was getting results as if there were almost no one cars passing by (Atached my countscompare). I was using a population of 5%, storagecapacityfactor of 0.2%, flowcapaityfactor of 0.3% and CountScaleFactor of 20. (I visualized the simulation with OTFVIS and there was vehicles passing, including some traffic jams)
After I runned with cadyts extension, my countscompare still the same, and the others outputs doesn't seems to change much (Or maybe i was not able to interpret the results very wel, if you have some userguide to help-me it would be usefull).
Follow attached my countscompares , my calibration stats and my config, maybe someine could give-me some help.
Thanks
