Hi Hector,


has the "pathtofile" an space or a strange character like ñ, ä or similar?

Betreff: [sumo-user] Changing rail to be bidirectional using netconvert

Sumo team,

I am trying to convert all of my rail network to be bidirectional using 
netconvert without affecting my roadway network. This is for 
commodity/container movement, not people movement. I am using a file I 
generated using OSM wizard.

I used this script:
netconvert --railway.topology.all-bidi.input-file 
C:\pathtofile\test_osm_in.net.xml.gz

This is the error I get.

Error: No nodes loaded.
Quitting (on error).

I recognize that the network file is a .gz file but both netedit and sumo open 
the network file as is and it has everything to include the nodes. Netedit 
crashes on me all the time while I am making changes to the file so I need to 
do this rail changes quicker using netconvert. I welcome any advice that will 
point me in the right direction.  Thanks,

--Hector

Hi Hector, you can try to process your network with netconvert using the 
PlainXML format: convert your network to PlainXML analyse your network with a 
script and write the missing edges in a new file in PlainXML format convert 
back to the normal

Hi Hector,



you can try to process your network with netconvert using the PlainXML 
format:

  *   convert your network 
to PlainXML
  *   analyse your network with a script and write the missing edges in a new 
file in PlainXML format
  *   convert back to the normal SUMO format with netconvert by supplying the 
PlainXML files using the respective input options (-n,-e,-x,-i)

Please write to the mailing list next time, so that everybody can answer the 
question (or at least learn from it).



Best regards

Mirko

Re: [sumo-user] Brake light flickering

[Matthew Jones via sumo-user]

Hello Mirko,

Thanks for the explanation.
We typically run at 1KHz and I think SUMO at 100Hz so that would explain it.
We will need to add a simple filter at our end.

Matthew.

Hi Matthew,



AFAIK brake light visualisation is pretty basic. Every time step it is decided 
whether to draw it or not. Now if you use very short time steps, you may 
encounter the mentioned pattern because in some situations SUMO vehicles do not 
come to a complete stop but travel at very low speeds (somehting like 0.01m/s).



Best regards

Mirko

Sorry if this has been asked before. It is very hard to google because of real 
car models like Tata Sumo!

In large traffic queues we see brake lights flickering much faster than real 
life.

I have found

https://sumo.dlr.de/docs/TraCI/Vehicle_Signalling.html
and
https://sumo.dlr.de/docs/Netedit/attribute_help.html
but these do not say how to configure the brake deceleration threshold.

Is this possible?

Thank you,
