Re: [sumo-user] Manual setup between phase state character and lane character and of connection in traffic light
|
Hi Andrea
for me the tests in SUMO are pretty helpful. If you downloaded
the complete SUMO you can issue under Linux a command like
find tests
-name '*.xml' -print0|xargs -0 grep -l connection.*link|grep
-v net.xml
This prints
the names of all xml files containing connection and link and
not ending with net.xml
You find for
example this test
tests/netconvert/function/tls_extended_attributes/
See also https://sumo.dlr.de/docs/Tools/Misc.html#extracttestpy
for extracting a test
You can specify the linkIndex
in a tll.xml file, which can be passed to
nextconvert via --tllogic-files
As far as I
understood link indices, every connection in a node must have
a unique linkIndex.
So if two
connection are controlled by one traffic light, you have to
give the appropriate letter twice in the phase definition.
Best regards,
Harald

Hi sumo community,
We are building a 3d visualizer that can create road networks
and export them to sumo using netconvert with the plain xml
files.
We are trying to insert traffic lights at desired junctions.
At the moment we are using the automatic generation using
netconvert with the “--tls.group-signals”
option by marking the type of the junction.
However is it possible to still have the
netconvert automatic generation but for each junction specify
which lane connection is associated with which character in
phase state string?
I have read previously that “linkindex” property might be
helpful for this, but I have the following questions:
- In which
file to I need to specify this parameter?
- Let s say
for a given lane I have side turns and going straight but I
want to use only 1 signal for all of these possibility
(basically instructing the group signal). Do I need just to
assign the same linkindex to all of the connections from the
given lane?
- Is there any
example of the plain xml file with the traffic light
information that should be given to netconvert to help the
program generation?
I would really appreciate any help,
Best regards,
Andrea
