Re: [sumo-user] Problem while importing shape file and creating TAZ
Hello,
for some reason the option --shapefile.guess-projection was not successful.
You can import the shapefile using the following options:
polyconvert --net-file osm.net.xml --shapefile-prefixes Example_Shape_Files/Export_Output_3 --shapefile.id-column FID_MD_SMZ ---proj.utm

note:
- option --proj.utm sets the correct projection
- osm.net.xml contains UTM coordinates which are shifted towards 0,0 to improve numerical stability. By passing the net.xml to polyconvert, the same shift is applied to the polygons.
- to improve visibility in the gui it is helpful to also add the polyconvert option "--shapefile.fill false" (this will generate only the outlines instead of  filled shapes)

regards,
Jakob

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
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

Hello,
the tool edgesInDistricts (
http://sumo.dlr.de/wiki/Tools/District#edgesInDistricts.py) can be used to
edgesInDistricts.py. Parsing a number of networks and taz (district) files with shapes this script writes a taz file with all the edges which are inside the relevant taz.


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.
regards,
Jakob

NETCONVERT is able to directly read binary ArcView databases ("shapefiles"). To convert such databases, at least three files are needed: a file with the extension ...

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
