[sumo-user] Import from OpenstreetMap

[<mic...@fr...>]

Hello
On a first step, I imported a city (#122525) from OpenStreetMap and "netconverted" the osm file on SUMO. Everything was correct on the SUMO GUI map.
On a second step, I made a slight modification on the given OpenstreetMap map of the city (with JOSM), which give no error when validating it. By the way, I uninattentionaly fusionned a pretty long chain of nodes (274 nodes)on a single lane, but without any error or even warning on validate.
On the resulting "netconverted", the corresponding  lane on SUMO GUI was missing with some other resulting isolated chains....
On a third step, I merely cut the suspected chain with JOSM on OpenstreetMap, carried out a new import of the osm file, convert it and everything is correct.
Am I wrong in saying that there is a maximum size of a chain of nodes for a lane or is there another hint ?
Anyway, having found a "solution" at least, I hope my mail will be useful, even from my poor experience.
Sincerely
Michel Souweine

[sumo-user] how to use an E2 type detector

[Khaled <khs...@gm...>]

Hi,

I was trying to include an E2 type detector in one of my simulations and I
included it in an additional file "*input_additional.add.xml*" and the
description in the file is as follows "*<laneAreaDetector id="D1"
lane="c21_0" pos="0" length="233" freq="1" file="detector.output.xml"
cont="false"/>*" for some reason the output file doesn't show in my folder
and I am not sure if the detector is working or not.

I am not sure if my configuration right or not, also is there any example
that can help understand how it works properly??

Thanks

[sumo-user] Defining a route for simulation.

[Oancea D. <do...@gm...>]

Hello everybody,

Walking through the SUMO documentation I have been able to build the
network (roads). The map was obtained from OpenStreatMap and converted
using the netconvert tool. I would like to define a route, and to run
simulator.  I have the following questions:
- how I can define a route for a give map?
- how can I know the length of the route?

Thanks

[sumo-user] Can SUMO record the time each vehicle passing different intersections?

[海. <183...@qq...>]

Dear:
  
        When veh3 passes the node5(the id of intersetion), the edge id is ":node5_16".
  
 I want to ask why come out "16"? The node5 have no neighbor node such as node16. 
  
 When a vehicle passes a intersection, how does the sumo get the edge id ?
  
      The part of netstate.xml file is listed as following:
  
         <timestep time="28.00">
        <edge id=":node5_16">

Re: [sumo-user] not support to Traffic Light

I had a first look at it and it seems like a SUMO bug. I will open a
ticket soon. The detector does not notice the vehicle entered because
it crosses the entry and leaves the edge in the same time step. So
moving the entry point a little bit upstream might help.

Re: [sumo-user] TLS Control state, response and foes - the net.xml file

[Daniel K. <d.k...@go...>]

Hello Bryan,

yes, "foes" indicates which streams can not pass the intersection at the
same time. "response" gives whether the stream defined by "index" has to
give way to one of the other streams. In your examples, stream at index=0
does not have to give way to other streams, and stream at index 3 has to
give way to stream at indices 4 and 5.

sincerely,
Daniel

[sumo-user] TLS Control state, response and foes - the net.xml file

[Bryan N. <k0...@db...>]

Hello,

I am working on my own TLS control I'm trying to decipher the net.xml file.  (The one that is the output of NETCONVERT.) 

I understand that in the tllogic section the state="rrrGGGGGg" refers to the lights controlling the internal lanes in the junction?

I can pick up which bit corresponds to which lane by looking at:
<junction id="JunctionRKLN" type="traffic_light" x="166.00" y="0.00" incLanes="RKL~SB_0 RKL~SB_1 Pell~WB_0 Pell~WB_1 BAve~EB_0 BAve~EB_1" intLanes=":JunctionRKLN_0_0 :JunctionRKLN_1_0 :JunctionRKLN_9_0 :JunctionRKLN_3_0 :JunctionRKLN_4_0 :JunctionRKLN_5_0 :JunctionRKLN_6_0 :JunctionRKLN_7_0 :JunctionRKLN_10_0" shape="159.45,8.05 172.55,8.05 174.05,6.55 174.05,-6.55 157.95,-6.55 157.95,6.55">

    <request index="0" response="000000000" foes="000110000" cont="0"/>
    <request index="1" response="000000000" foes="000110000" cont="0"/>
    <request index="2" response="000110000" foes="111110000" cont="1"/>
    <request index="3" response="000000000" foes="100000000" cont="0"/>
    <request index="4" response="000000011" foes="100000111" cont="0"/>
    <request index="5" response="000000011" foes="100000111" cont="0"/>
    <request index="6" response="000000100" foes="000000100" cont="0"/>
    <request index="7" response="000000100" foes="000000100" cont="0"/>
    <request index="8" response="000111100" foes="000111100" cont="1"/>
    </junction>

So I would understand that :JunctionRKLN_0_0 :JunctionRKLN_1_0 
both have the same foes :JunctionRKLN_3_0 :JunctionRKLN_4_0 ?

*** What is the response attribute telling us?

To figure out the mapping for :JunctionRKLN_0_0 I can look in the net.xml file and find the:
    <connection from="RKL~SB" to="BAve~WB" fromLane="0" toLane="0" via=":JunctionRKLN_0_0" tl="JunctionRKLN" linkIndex="0" dir="r" state="o"/>


Thanks,

Re: [sumo-user] Edge definition without function attribute

[Michael B. <beh...@us...>]

Hi,
the default value is "normal" and "connector" is probably just missing
from the schema since it is only used by the VISUM importer and we
don't have enough VISUM example networks. "normal" is not in the
schema because the schema tries to focus on what netconvert really
creates and "normal" is usually left out.
Anyway, I added them both to the schema.

Thanks for pointing this out,
Michael

Re: [sumo-user] Multiple Agents through TraCI

[Bryan N. <k0...@db...>]

I am taking the approach of a central Communications/Liaison agent that interacts with TraCI.
Other agents then interact with the Liaison via RabbitMQ.  http://www.rabbitmq.com/

For a graphic representation, you may want to check out the System Context diagram among others in this document:
http://people.cis.ksu.edu/~bnehl/nehl_implementation_architecture_design.pdf 


Links to associated (in progress) code/git repo and other documents are available at my website: http://people.cis.ksu.edu/~bnehl/

Re: [sumo-user] Multiple Agents through TraCI

[Gregory J. B. <gj...@cm...>]

I have written an interface like this in Python, though it might not be 
exactly what you're describing. We've been developing a distributed 
adaptive traffic signal system that we'll be field testing starting next 
week. To be able to test everything in the lab, we can substitute SUMO 
for the real detectors and controller using this interface. The 
interface I've written has a very limited set of functions, but there is 
no reason one couldn't write something that opened all of TraCI to every 
client. One of the difficulties is deciding how fast simulation steps 
can occur. We typically run at a constant rate, often at real time (1 
second in simulation takes 1 second).

The interface I've written is very specific to our application, so it 
would be difficult to share, but I'd be happy to collaborate on a more 
general system that allows multiple clients to work with TraCI. I'm 
curious if there are others out there who would be interested.

[sumo-user] Multiple Agents through TraCI

[Guilherme A. <gg...@in...>]

Hello all,

I've been working with some colleagues on agent-controlled
traffic lights and vehicles separately, using the TraCI API
for python.

We'd like to integrate them, however we had some
difficulty doing it since the TraCI clients are monolithic.

Is there any tool that centralizes communication with
SUMO, allowing more clients to work at once?

I understand there are some difficulties with synchronizing
them all (e.g. don't let the traffic lights module request a
simulation step until the vehicle router is done for this step),
but there should be some way to handle it.

Thanks in advance!

What makes you think it fails, any error messages appearing?
Anyway this is the wrong approach, see below.

First of all, this is the right way to do it.
Second, what does it do instead? Errors/warnings any output at all?

Re: [sumo-user] DFRouter problem

[SEBASTIAN R. <17...@st...>]

Hi Matthew,

I figured it out by myself. A *.sumo.cfg has to look like this:

<input>
        <net-file value="grid.net.xml"/>
        <gui-settings-file value="grid.gui-settings.cfg" />
        <additional-files value="grid.rou.xml grid_detectors.det.xml
grid.emi.xml" />
    </input>

I would add that to the Wiki, if I could get some rights to write into
it. There is also a mistake here:
http://sourceforge.net/apps/mediawiki/sumo/index.php?title=Demand/Routes_from_Observation_Points#Computing_Flows

-detector-files <STRING> should be --measure-files <STRING>

I would change this as well :)

[sumo-user] Edge definition without function attribute

[Simon S. <sim...@ar...>]

Dear all,

if netconvert creates an XML edge element without a function attribute,
what is the value of function then? The wiki page Network/SUMO Road
Network does not mention that function is an optional attribute.

Following the XML Schema, it seems function may only have the value
“internal” any more. “Normal” and “connector” are not allowed.

Here is a sample definition


<net version="0.13"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://sumo.sf.net/xsd/net_file.xsd">

...

    <edge id="-46201679#0" from="42447428" to="42451593" priority="9"
type="highway.primary">
        <lane id="-46201679#0_0" index="0" speed="27.78" length="67.71"
shape="1804.35,1930.74 1741.06,1954.80"/>
        <lane id="-46201679#0_1" index="1" speed="27.78" length="67.71"
shape="1803.18,1927.66 1739.89,1951.71"/>
    </edge>
 

Thanks for your help

Betreff: Re: [sumo-user] DFRouter problem
 
Hi Everyone,

I struggle with the same problem you describe above. Was the solution
to this problem only to change the 2 lines in the *.sumo.cfg?
<route-files>routes.rou.xml</route-files>
<additional-files value="emi.emi.xml" />
to
<additional-files value="emi.emi.xml routes.rou.xml" /> ?
I also delete the routes-files line...

Because it does not work in my case. I always get errors like:
Error: Invalid reference to route '25452783#0_to_50635948' in route
distribution 'I1-1'.
Error: The route '25452783#0_to_-28664469#0' for vehicle
'emitter_I1-1_900000' is not known.
Loading of additional-files failed

The dfrouter generates all necessary files and the content seems
correct to me, like you describe above. I tried it with sumo-0.13.1
and sumo-0.14.0.

Best regards,
Sebastian

Re: [sumo-user] about ActivityGen

[Simon S. <sim...@ar...>]

Hi Ion,

in the population description file, most fields must be given as we do
not know reasonable defaults for them. It might be though that
ActivityGen is a bit too critical for historical reasons. You could send
me your SUMO network and your population file, so I can test it and
maybe adjust the ActivityGen code a bit to contain more defaults.

The way I do create the population file is using eWorld. I wrote a
plug-in that lets you input all values of the population file. It
considers more defaults, even defaults for the street properties. The
plug-in addresses your second question, too. It knows all streets and
puts out a population file that contains all of them.

Downlaod eWorld 0.9.3 and start it. Then import the SUMO network (not
the OpenStreetMap file, because that has other edge ids). For a simple
first test, immediately export the population file. This should put out
a file only from defaults. Then you can use the population dock and the
settings menus in eWorld to adjust all the parameters you know. Finally
export a population file again. It should contain all your settings.

Best regards

Simon

[sumo-user] How to use Netconvert ?

[drahte1905 <dra...@gm...>]

Hi;

I coudn't run the netconvert, I have placed my

nod.xml
edg.xml
typ.xml
con.xml
and config file under the same directory
[C:\Users\drahte\Desktop\sumo-0.15.0\bin] with the netconvert.

When ever I double click the netconvert under this directory it crashes, I
run it "as administer" but again it fails.

I also opened another CMD window and change my directory
to [C:\Users\drahte\Desktop\sumo-0.15.0\bin] and than used the command
"netconvert
–c quickstart.netccfg" but again it do not create NET.XML file.

Thanks so much I appreciate your help.

[sumo-user] about ActivityGen

[florie <ion...@gm...>]

Hi,

I am new to SUMO, and am wondering if every parameter from the tutorial has
to be set (as I do not have some of the statistics for the study area).
Right now, supplying minimum information I am getting the error "Quitting
on unknown error". Also, is there an automatic way of generating all the
edges and nodes name as
it is hard to distinguish which one is which from the SUMO-GUI.

Thanks so much I appreciate your help.

Re: [sumo-user] SUMO Queue Estimation Algorithms

[Michael B. <beh...@us...>]

Hi,

SUMO uses a microscopic simulation, that means every vehicle is
simulated individually and we don't need queue estimation. There are
different models concerning car following (e.g. IDM, Krauss, Kerner)
you may choose from (in the XML input files) when using SUMO.

Please provide the exact steps which took you here. Somehow the
vehicle type "car" must have been come into the route file, so
probably you told duarouter to add it. Just leave out this option or
define a vehicle type car and load it as an extra route file (it is
not hard, see the docs).
