Re: [sumo-user] custom attributes in xml definitions with netgenerate

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

the recommended way to add custom information is to use the <param key="KEY" value="VALUE"/> element as child element of junctions, edges and traffic lights. Custom attributes will not be picked up by netconvert.

We recently added capabilities to also support <param> for <connection> but this is currently not handled when importing from .con.xml file (only when reprocessing a .net.xml file).  A work-around would be to encode the information in the lanes or traffic light. (e.g key="LINK_INDEX" value="isTurn"/>. Loading tlLogic params from .tll.xml is supported by netconvert.

Note, that .net.xml already encodes the turning direction for every connection (straight, left, right, turn-around) in the 'dir' attribute.

regards,

Jakob

Hi everyone,

I am currently using the plain xml format to define my sumo networks and
then use netgenerate to generate the net file.

All of that works fine, but I was wondering how I could extend the
format for my own needs while still being able to use netgenerate?
More specifically I need to put some additional information on traffic
signals (like is it a turning signal and some other information). I was
thinking about using the connections xml file to define this and then
basically end up with entries like this:

<connection from="x" to="y" fromLane="1" toLane="1"
connectionType="turning"/>

My problem now is that I will lose this custom attribute
'connectionType' in the net xml file generated by netgenerate.
Is there anyway to achieve this? Can I extend the xml schemas with my
own and still use netgenerate? Or is this there any other way of
encoding my custom information?

Thanks for your help in advance.

Best regards,
Tobias
