Hi Martin,
depending on the purpose of the simulation, you could also
consider modelling the pedestrians with regular edges and links.
If the purpose, as far as the pedestrians are concerned, is solely
to have someone cross the intersection every now and then (that
is, you are not interested in modelling the pedestrians in detail,
or measuring throughput etc.), that should do just fine.
You could model the pedestrians as vehicles, which means they will
queue in line for the traffic lights, and SUMO will complain.
However, it also means that pedestrians will be able to activate
E2 detectors (which I believe they cannot as actual pedestrians),
and it makes building the network somewhat easier.
Below is a screenshot of a network in which I followed this
approach. Note that there is a single traffic light that controls
multiple junctions.
Personally I have found no other way to model pedestrians that
allows me easily place the crossing correctly, and also allows a
destination for pedestrians where there is no other edge.

Dear
Jacob,
I don’t know if you pay attention to my
problem? The problem is that when I add sidewalks to the
incoming edges of an intersection, the pedestrian crossings
are valid, but the connections on the incoming edges are
messed up. What is the solution for this? Or maybe someone
else has dealt with this problem?
Best

Thank you for your answer Jacob,
I did the changes according to your advices.
That worked fine. The warnings have disappeared. But this
change has a nasty side-effect. All the connections with
edges that have sidewalks seems to be messed up. This is
also visible in Netedit:
How can I get the connections fixed according
the .con.xml without changing manually in Netedit or in the
.net.xml? My goal is to make a SUMO network automatically
from an an existing standard intersection topology.
I included my files again.
Kind

Onderwerp: Re: [sumo-user] invalid pedestrian crossings
netconvert rejects
crossings that do not have a sidewalk or another
crossing on each side.
Invalid crossings
are not written to the .net.xml files and therefore you
cannot find them.
To better understand
the problem, it helps if you load the input files
directly into netedit (use the same command with netedit
instead of netconvert).
Netedit will color
invalid crossings in red (requires pressing F5 once).
Also, the latest
development version of netconvert and netedit give
additional information in the warning message.

Dear SUMO-users,
I get warnings using netconvert that
says:
Warning: Invalid pedestrian topology:
crossing ‘:KR27_c3’ has no target.
Warning: Invalid pedestrian topology:
crossing ‘:KR27_c5’ has no target.
In .net.xml the edges don’t exist.
The strange thing is that all the
other pedestrian crossings are converted into
.net.xml correctly. The input-files seems logical,
so I don’t know what I’m doing wrong here.
Does anyone have suggestions?
I added all the files. The call is:
netconvert
--node-files=Output/KR27.nod.xml
--edge-files=Output/KR27.edg.xml
--connection-files=Output/KR27.con.xml
--type-files=Output/all.typ.xml
--tllogic-files=Output/KR27.tll.xml
--output-file=Output/KR27.net.xml
Met
vriendelijke groet,
