[sumo-user] Error: Invalid linkIndex -- no sidewalk connections connections exported

[Joerg S. <joe...@un...>]

Dear SUMO team,

when building a net.xml file with netconvert from edge.xml, nod.xml 
con.xml and tll.xml I obtained this error when opening with sumo-gui:

Error: Invalid linkIndex '16' in connection controlled by '1/1'

I looked into the xml files to see what happened:
netconvert does not export connections between sidewalk, neither to the 
con.xml nor to the tll.xml file.

Clearly, such connections of the net.xml file

<connection from=":1/1_w0" to=":1/1_c3" fromLane="0" toLane="0" tl="1/1" 
linkIndex="19" dir="s" state="m"/>

do not show up in the con.xml or tll.xml file.

But (I do not know exactly since when), the traffic light signal state
in the tll.xml does also include the signal states for the pedestrian 
crossings. Thus the signal state contains more signals than there are 
connections, because the connections for crossings are missing.

Now, when re converting such a ttl file to a net file with netconvert, 
sumo complains about this inconsistency and refuses to run the simulation.

Attached is a simple ttl.xml file with such an inconsistency using 
version dev-SVN-r24885

Any suggestions how to deal with it? Would it be possible to export the 
pedestrian connections too?

Best wishes,
Joerg
