Hello Jakob,
I have simulated a traffic scenario and got 2GB route file but it is
not opening in SUMO GUI. Also I want to retrieve some data from route
file. Do you have any python script to retrieve the data from big
size route file. Thank you in advance.

Subject: Re: Problem while importing shape file and creating TAZ
Hello Jakob,
Thank you for your feedback. As suggested, I tried using Polyconvert
to generate poi.xml file. I was able to generate the same. But the
tool edgesInDistricts takes two inputs, one is the network input and
other one is the polygon xml. The network input is extracted from
OpenStreetMap for approximately the same area as shape file .
osm.net.xml and polygon xml were fed as input to the tool
edgesInDistricts. I am attaching xml output from polyconvert. Please
suggest the way further.
Command --
edgesInDistricts.py -n
"C:\Users\Bhushan\Documents\ArcGIS\Example_Prince George\osm.net.xml"
-t "C:\Users\Bhushan\Documents\ArcGIS\Example_Prince
George\shp.poi.xml" -o "C:\Users\Bhushan\Documents\ArcGI
S\Example_Prince George\shp.taz.xml"
I found an assertion error as mentioned below:
Traceback (most recent call last):
File "C:\Program Files (x86)\DLR\Sumo\tools\edgesInDistricts.py",
line 188, in
<module>
reader.computeWithin(polyReader.getPolygons(), options)
File "C:\Program Files (x86)\DLR\Sumo\tools\edgesInDistricts.py",
line 44, in
computeWithin
districtBoxes[district.id] = district.getBoundingBox()
File "C:\Program Files
(x86)\DLR\Sumo\tools\sumolib\shapes\polygon.py", line 4
7, in getBoundingBox
assert(xmin != xmax or ymin != ymax)
AssertionError
Also, regarding item 1 in previous post (mentioned below) , how can we
generate a network using the shape files? I am attaching the required
shapefile for reference.
First problem here is that when I try to use these shape files, I
cannot find any reference to street id, from id (name of the node the
edge starts at) and to id (name of the node the edge ends at) which
are required when using netconvert command with shape files
(http://sumo.dlr.de/wiki/Networks/Import/ArcView). Can you please
guide how to generate a network with given shape files?

Hello All,
I am a new user of this tool and found very useful in my current
graduate research.
I am trying to build below scenario but not able to proceed ahead. I
am using Sumo 0.31.0 version.
1. Import real world shape files (Geometry type: Polygon) with 6
distinct zones.
2. Import corresponding OD Matrices to generate traffic demand
using od2trips.exe.
First problem here is that when I try to use these shape files, I
cannot find any reference to street id, from id (name of the node the
edge starts at) and to id (name of the node the edge ends at) which
are required when using netconvert command with shape files
(http://sumo.dlr.de/wiki/Networks/Import/ArcView). Can you please
guide how to generate a network with given shape files?
Second problem is that for using od2trips.exe, we need to provide
TAZ.XML file with taz_id and corresponding edge id in each zones.
Right now I tried to create this input XML file manually and able to
generate trips. However, this is not possible to generate this file
manually if network is large. Is there any existing tool/script to
generate TAZ XML from given shape file (geometry type: Polygon).
Do let me know if you need to view shape files.
Please guide.
Thanks in advance.

Hello,
in the latest development version, the MSLaneChanger constuctor already
sets a flag for each lane which defines whether changing to the left or
right is possible.
I've outlined a rough implementation draft here:
https://github.com/DLR-TS/sumo/issues/3656
[https://avatars0.githubusercontent.com/u/6240630?s=400&v=4]<https://github.com/DLR-TS/sumo/issues/3656>
allow asymetrical lane-change restrictions · Issue #3656 ·
DLR-TS/sumo<https://github.com/DLR-TS/sumo/issues/3656>
github.com
use lane information to set MSLaneChanger::ChangeElem::mayChangeRight
and mayChangeLeft flags when no neigh (or only opposite neigh) are
defined, all directions are allowed when at least one lane ...
Patches are welcome (-:
regards,
Jakob

Hi Gerald,
the solid line mark case can be solved either by separating into two
separate edges or by introducing a very narrow lane which forbids all
vehicles (the latter is probably better).
For the asymmetric case it is a little harder. We introduced the
concept
of defining neighboring lanes explicitly in a network which we needed
for the opposite direction driving but I am pretty sure, this cannot
be
used yet to limit the lane neighbors for lanes of the same edge. But
if
I wanted to implement something I would follow this path. For an
impression how this looks in the net:

Hello,
the tool edgesInDistricts (

generated the TAZ files automatically from polygons.
The polygons must be in the xml format generated by Polyconvert and
describe the outline of the TAZ.

Hello,
I am trying to use SUMO to control an automated intersection. If I set
the
priorities of a node that two lanes pass through to be equal, one of
the
lanes yields to the other. If I set the mode to be "unregulated" the
cars
wind up passing through each other. Does anyone know what mode might be
best for this purpose or do I need to write my own code to detect
crashes?
Thank you,
Eugene Vinitsky
