Thank you for your help. Do you have any web page or related weblog?

Re: [sumo-user] TL Logic validation

[Jakob Erdmann]

Hello,
netconvert returns basically two types of signal plans depending on the
edge priority values at an intersection
1) streams in opposite directions at the same time, seprate phase for
exclusive left turns
2) every incoming edge gets its own phase where all turning directions get
the green light

There are a lot more valid states and signal plans so feel free to design
your own.

- You will receive a warning when loading a signal plan without yellow
phase between the green and red phase.
- When you make your yellow phases to short (relative to road speed), you
will see 'emergency braking" warnings from the simulation
- if you allow incompatible streams at the same time you may see collisions

regards,
Jakob

Re: [sumo-user] How to export the network as a graph

[Jakob Erdmann]

Hello,
you can do this in 2 steps (first convert the network to the so-called
plain format, then convert this to csv):
1) netconvert -s yournet.net.xml --plain-output-prefix plain
2) sumo/tools/xml/xml2csv.py plain.edg.xml

regards,
Jakob

[sumo-user] How to export the network as a graph

[Reza Mortazavi]

How can I use SUMO (or netconvert) to export a *.net.xml file to an
adjacency matrix of a graph (ex:  *.csv format)? I want to plot it in
Matlab as a weighted graph where the edge weights (i.e., the adjacency
matrix entries) are their associated length or 0 if two nodes are not
connected. My best effort was to use  "netconvert --amitran-output", but I
have to process again the output to become a csv file. Is there any more
direct way?
Thanks.
