[sumo-user] moveToXY change position

[謝昀宸]

Dear Sumo team,
I want to park the vehicle on the side of the edge.
When the vehicle is parked in the middle of the road, use moveToXY to
fine-tune the position of the vehicle to the far right side of the road.

But when the vehicle touches the edge of the road, it will automatically
adjust its position,  just like the attached gif.

I tried various parameters of Keeproute, but it still does not improve

[sumo-user] edge or lane MeanData output

[Sasan Amini]

Dear SUMO team,

when I set the excludeEmpty to false in meanData definition, empty edges
(or lanes) have only a few attributes from the full set (for example,
speed, density, occupancy etc. are not included). In case the first line is
an empty edge (or lane) the sumolib.output.parsing() function cannot parse
these attributes for the remaining edges. Also, when converting the xml to
csv without specifying the schema those columns won't be created which
means setting the option excludeEmpty to False has no effect. Would it be
possible to generate the full list of attributes even for empty edges
(lanes)?

Best,
Sasan

[sumo-user] Why does vehicle start to use fuel when it is still standing on the lane?

[nohtyp]

I created simulation with tls intersection.
scenario.zip
  
In scenario.zip you can find sumo config files + plots + output generated by
sumo-gui
(simple.out.xml)

See tls_vehicle_1_motion.png and tls_vehicle_1_moment_fuel.png. Vehicle 1
stops moving at 20 s and starts again at 45s.
But this vehicle starts to use fuel at 30s. If it uses fuel when idling, why
it doesnt use fuel from 20s to 30s? Could you explain this behaviour?

Best regards,
Piotr

Re: [sumo-user] geo-position of stops

[Michael Behrisch]

Hi Max,
in which way are the x,y coordinates wrong? Can you send your input files?
When converting from x,y to lon lat you need to leave out the last
parameter (True) which is only needed when converting raw UTM coordinates.

Best regards,
Michael

Dear Andras and Lokesh,

Thanks for your reply! Unfortunately, even with seed and random my
simulation is generating the same flow in different simulation runs. I
tested this in v1_7_0 tag and in master branch with all current changes. Is
this working for you? If so, it's probably a problem in my build...

Re: [sumo-user] Unable to see vehicle (Hello World)

[Michael Behrisch]

Hi,
concerning the missing vehicle, please check the log for any error
messages / warnings.
Concerning the netedit version, I would also assume that you have some
hidden second version or that the uninstall did not finish properly.
Does netedit show the right version when you start it from the start
menu or the command line?

Re: [sumo-user] Cannot run state saved from previous version

[Michael Behrisch]

Hi Abdullah,
states are not meant for long term saving, so you cannot use a 1.3.1
state with sumo 1.7.0. Depending on the size there is a small chance you
might be able to convert it by hand but it is not something which is
easily done.
Usually new states contain more values which you will not be able to
recreate without rerunning the simulation.

Best regards,
Michael

Re: [sumo-user] Different probability flows between simulations

Maybe initializing the simulation with a different random seed would solve your

Tárgy: [sumo-user] Different probability flows between simulations

hello,

I'm generating a flow of vehicles with probability='0.3' as seen in the code 
below:

 
  


It works correctly and generates the random flows I need during the simulation. 
However, I noticed that if I execute the simulation again it will generate the 
same random flow as the previous execution. Can you tell me if this is the 
expected behavior of random flow? I need to generate different flows in each 
simulation execution. Is there any way to do this?

Thanks in advance!

Hi Tiago,

>From the heading, it seems that you want to change the vehicle injection
probability in every simulation run. If it is, you can do it in two ways:
i) manually- every time change probability value in route file or ii)
dynamically- change it using TraCI API. However, if you want with the same
probability every simulation should have given you a different flow, just
change the default seed value (23423; see
https://sumo.dlr.de/docs/Simulation/Randomness.html). You can do it using
 in *.sumocfg file. It simply uses the system
current time as a seed value.

Re: [sumo-user] geo-position of stops

[Maximilian Socher]

Hi Giuliana,

thanks for your reply. I am currently working on a script based on your
input, however the coordinates I'm getting are way off.

I'm extracting the laneID and lanePos from my ptstops.add.xml. These are
correct. The x and y-coordinates I recieve from
/sumolib.geomhelper.positionAtShapeOffset(net.getLane(laneID).getShape(),
lanePos)/ however are way off. 
So are the lon and lat (obviously /net.convertXY2LonLat(x, y, True)/ already
calculates on wrong x and y, but even with hardcoded correct coordinates the
lon, lat I recieve are just off the coast of Ghana whereas my network is a
city in northern Germany).

Any idea where I might have went wrong?

Regards,
Max
