Re: [sumo-user] WG: AW: multi-lane area detector (e2) value retrieval bug

[Michael Behrisch via sumo-user]

Hi,
can you please post the output of traci.getVersion() / 
libsumo.getVersion() on both systems?

Thanks!

Best regards,
Michael

Hi Mirko,

sorry for the delayed feedback. Working with sumo version 1.19, it seems 
that the problem persists only in Windows 11 not in Linux (Ubuntu).


Best regards,

Hi Manos,

on my side it looks fine. Are you sure you use the fresh libsumo
version? The change in source code is not related to libsumo/TraCI
itself but to data storage of detectors, so there shouldn't be any
difference on how you access the data.

Best regards

Mirko

Mirko I found what is the fault. If you set file="NUL" inside
the e2 detector definition, the last interval occupancy does not
work (returns always zero). This is not the case for e1
detectors where last interval occupancy works in both cases (set
"NUL" or give an xml path).  If you still need a sample scenario
let me know.

Hi Manos,

I cannot reproduce the problem. Our TraCI tests regarding
lane area detectors do not show anything similar. Would you
be willing to share a sample scenario and your TraCI script?

Hi all,
I have created a corridor where I have placed a multi-lane
area detector (e2) with a period of 300s and I want to
retrieve last interval occupancy via traci or libsumo. In a
previous project, I have done the same with induction loops
(e1) and it works as follows. If the detector has a period
of 300s for example, the interval occupancy is the running
mean within the period of 300s. When the simulation time
modulo (%) the period (300s) is 0 the interval occupancy
becomes zero and the last interval occupancy value is
updated. Within the period the last interval occupancy
remains constant. It seems that there is some bug in
multi-lane area detectors when it comes to the last interval
occupancy value retrieval because it always remains zero. I
have provided a printed output for 898 seconds (1 - 899s).
The first column is the simulation time, the second is the
last step occupancy, the third is the interval occupancy and
the fourth is the last interval occupancy. The results are
the same for traci and libsumo.
Best regards,
Manos

Re: [sumo-user] libsumo DLL load error

How should I solve this problem?

Thank you so much for your kind response and good insights all the time.

Re: [sumo-user] Multiple environments in reinforcement learning

[Michael Behrisch]

Hi Jordan,
can you give more details on your system? Some systems limit the nummber 
of open sockets or have a large delay on freeing a closed socket 
(especially Windows). If this does not apply here I am afraid you can 
only try to catch the exception and restart the sumo instance possibly 
after some wait.

Re: [sumo-user] Fuel consumption model parameters

Hi,
the parameters have always been for milligrams. Before the change in

would like to know the specific fuel consumption model that is
used and the parameter values of it. I found the model from this
paper (https://elib.dlr.de/89398/1/2ndGenEmissions.pdf

Re: [sumo-user] Emission Class values

Hi,
the answers are inline.

Am 25.09.22 um 14:57 schrieb UTA - Std - Kenny Assunção:
I saw that there is an error percentage 
associated with each type of emission, I would like to know if this 
error percentage is relative to reality or is it relative to the old 
model (HBEFA3).


The error shows how good our (polynomial) fit resembles the original 
HBEFA4 data. This is just an average over all speeds and accelerations
in the range where HBEFA has values, so this does not mean that any 
standardized driving cycle will show this error.


The second question is about the emission class "Energy", the class for 
electric vehicles, the noise values for the electric cars simulated are 
practically the same or even higher than fuel cars, maybe this doesn't 
make sense.


The noise model currently does not take the propulsion method into 
account. It is tailored for combustion engines only. I opened an issue 
here: https://github.com/eclipse/sumo/issues/11767

Re: [sumo-user] Regarding Emissions Class 4

Hi Radha,
there have been major changes to the emission models and the data basis 
for CNG is not that strong but I found that increase also strange. Is 
this straight driving with constant speed or a stop and go scenario?

Hello,

Recently I changed my simulations from emission class 3 ( 
|HBEFA3/PC_G_EU4| ) to 4 (HBEFA4/PC_CNG_petrol_Euro-5_(CNG)), and from 
EU4 to EU5.


I have difficulty understanding the emissions. In class 3, to travel a 
1000meters vehicle, consume 85 to 170ml. When I check class 4, the fuel 
consumption is showing above 40k ml. Is this correct? or is there any 
error in storing the emissions data, for instance interchanging the data 
between CO to fuel and vice versa?


Am I reading this correctly?

Re: [sumo-user] libsumo.libsumo.FatalTraCIError: A network was not yet constructed.

[Michael Behrisch]

Hi,
it may also be that you did call start but the parameters were invalid. 
Do you change the sumo config / the input files between the runs? So you 
may accidentally give an invalid input in the 232nd run.


Best regards,
Michael

Hello,

I have been running SUMO along with a reinforcement learning algorithm 
that reruns a TraCI simulation from scratch each episode. When I was 
placing a static blockage (stopped vehicle) in the same location every 
episode, it was working just fine. But now that I am changing the 
location and size of this blockage every episode, after a certain number 
of 'episodes' (232, to be precise), SUMO throws an error:


File "/.../marlenvironment.py", line 797, in step
     for vh in self.simulation.traci_handler.vehicle.getIDList(): #
Set LC mode from the beginning
*libsumo.libsumo.FatalTraCIError: A network was not yet constructed.*

are the SUMO-relevant lines from the stack trace that causes the system 
to stop functioning.


My understanding of this is that it is telling me that I am calling 
traci.start() before a traci.close() was called on a previous 
traci.start() - But I am unsure how to debug this and cannot see how 
this could have happened with the change I mentioned above, and why it 
happens only after 232 runs of the simulation?


Please advise. Thank you.

Sincerely,
Hriday

Re: [sumo-user] Emission models problem

[Michael Behrisch]

Hi Ali,
thanks for picking it up again. So here is what we currently do:
Whenever the deceleration is small enough and the speed is still above 
some threshold we assume the vehicle is coasting and set all emissions 
to 0. We essentially copied this behavior from the PHEMlight model but 
now that I think of it again I am not really sure why this is a good 
idea (i.e. why we do not use the idling emissions for a standing vehicle 
here). I just double checked and the behavior is still there in the 
newest PHEMlight so at least it is consistent. I opened a ticket here:

https://github.com/eclipse/sumo/issues/11198

Michael

Re: [sumo-user] Motorbike emissions

[Michael Behrisch]

Hi,
the way Jakob described it works here as well. I renamed now the folder 
to PHEMlight5 to have a better correspondence between model name and 
folder name. Please try again with the nightly build of tomorrow.
Also please make double sure that you are using the latest nightly build 
and have no typos in your input files (maybe also send your input files).


Best regards,

Also, after running some tests, I've become with another issue.
If I define the following emission class, using the naming of the 
PHEMlight5 files: PHEMlight5/RT_EUIII_D_I, I get the same "emissionClass 
not found" error. However, when I use the naming from the documentation 
(i.e.: PHEMlight5/HDV_RT_I_D_EU3 ), documentation I get no error. This

Although your previous message was useful to correct the

with the latest development version:

I'm a bit confused about why SUMO isn't finding these emission
classes neither when all the files are in the folder 
data/emissions/PHEMlight/V5/ nor in the

folder data/emissions/PHEMlight. However, for passenger cars and
LCV vehicles it works fine.

Thanks Jakob. So the following remarks appearing on the

*motorcycles - 4 stroke (not included)

Motor cycles are only available for the old data set

do not indicate the impossibility of using motorcycles
data sets, right?
And can you confirm the following is the correct
nomenclature to call the motorcycles emission classes?

MR_G_EU0_2T MR_G_EU0_4T

This is the nomenclature that is shown in the
documentation but it raises the error

/Error: emissionClass with name 'PHEMlight/MR_G_EU1_2T'

For any other vehicle types (passenger, light and heavy

The two warnings are unrelated:

- "No mapping library found"  can be ignored. There is an option that 
permits using a proprietary map matching engine but the 'tracemapper' 
default should work fine.
- "No net resources\gtfs\bus.net.xml" indicates that the filtered 
mapping networks (i.e. one for bus, one for tram) could not be created. 
The filtering currently assumes an OSM-derived base network with edge 
types such as "highway.primary" or "railway.tram"). If your network 
comes from a different source, this process will fail.

Re: [sumo-user] Typing with Pylance with parallelized simulations

Hi Patrick,
currently the traci library dynamically inserts the domains into the 
connection using setattr. This confuses most autocompletion tools which 
only do static analysis. Maybe this thread helps:

https://stackoverflow.com/questions/63436496/is-it-possible-to-have-python-ides-offer-autocompletion-for-dynamically-generate

Hello,

I run multiple parallelized sumo simulations using traci. This works out 
quite fine.


To mitigate the need to use always the traci switch command, I store for 
each simulation a traci.Connection object using traci_object: 
traci.Connection = traci.getConnection(id). This works fine.


But my issue with that way is, that in VS Code where I write my python 
code to interface SUMO using traci gives nice code completion when I use 
traci.vehicle.getSpeed(id) but not with 
traci_object.vehicle.getSpeed(id). There it does not offer 
vehicle.getSpeed(id) and marks it as "Cannot access member vehicle for 
type Connection". What would be the right way to write the code?

Hi Rob,
thanks for the feedback. I think the best way to install the python

The difference - as I found out: On the notebook, miniconda3 is

~/miniconda3/bin/. And the path is already okay.


I'd suggest to advice the users (on the download page) to use sudo in 
order to simplify things.
Hi 
When I install miniconda3 on the desktop, the install without sudo (a 
necessary condition to keep a package manager based install upright) 
goes without warning - which confirms that the finding is correct.


ANOTHER FINDING:
When the package manager based install is removed, after starting 
sumo-gui fom python install, a load error occurs on loading an

[sumo-user] SUMO 1.11.0 update released (log4j vulnerability)

[Michael Behrisch]

Dear friends and users,
although only a small part of the SUMO universe is running with Java,
we are not entirely unaffected by the most recent events. Good news
first: If you are not using lisum-gui
(https://sumo.dlr.de/docs/Tools/LiSuM.html) or not even know what it is
you can stop reading now.

For all the others:
Please note that due to the log4j vulnerability
(https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44228) the
lisum-gui.jar in the distribution 1.11.0 has been replaced. Until today
it contained a vulnerable version of the library. All other files are as
in the original release. So if you are a lisum-gui user please download
and install the release again. You can also download an updated
lisum-gui.jar directly: https://sumo.dlr.de/daily/lisum-gui.jar. Please
note that no other part of SUMO (not even lisum-core.jar) is affected
and also our web server https://sumo.dlr.de is not running Java code.

(Older releases however still contain the vulnerable code in
lisum-gui.jar and will not be replaced.)

So now enjoy your holidays if there are any ahead of you and keep
simulating!

Best regards,
Michael (for the SUMO team)

Hi,
the fastest way is to use command line sumo without any external control
but libsumo should be right next.

Hi,
Libsumo ist picky about types. So you need to convert everything to a string 
before calling setParameter.

[sumo-user] Upcoming SUMO 1.11.0

[Michael Behrisch]

Dear SUMO friends, users and developers,
we recently promised to inform earlier about upcoming releases, so this
is to announce that we are planning to release SUMO 1.11.0 on 23.11.2021.
So please do heavy testing of your scenarios and code with a nightly
build _now_ to let us repair all the glitches and have a shiny release.

Please note that the Linux repositories on the open build service have
changed and we are now residing on
https://build.opensuse.org/project/show/science:dlr. The links on the
download page https://sumo.dlr.de/docs/Downloads.php are already updated.

The easiest way to check out a nightly build without messing up your
existing SUMO installation is probably to use a python virtual
environment. Here are the commands to do so:

python -m venv sumo_test
cd sumo_test
. bin/activate (or activate.bat on Windows)
pip install -i https://test.pypi.org/simple/ eclipse-sumo

We are looking forward to yur feedback!

Best regards,
Michael (for the SUMO team)

Re: [sumo-user] Assert Error in traci method

[Michael Behrisch]

Hi,
I suppose you are using this input:
https://github.com/LucasAlegre/sumo-rl ? If I start a similar script
here it works just fine.
Here is my code:

#!/usr/bin/env python
from __future__ import print_function
from __future__ import absolute_import
import os
import sys

sys.path.append(os.path.join(os.environ.get("SUMO_HOME", SUMO_HOME),
"tools"))
import traci  # noqa
import sumolib  # noqa

traci.start([sumolib.checkBinary('sumo'), '-n', '4x4.net.xml'])
ts_ids = traci.trafficlight.getIDList()
print(ts_ids)
traci.trafficlight.getRedYellowGreenState(ts_ids[0])
programs = traci.trafficlight.getAllProgramLogics(ts_ids[0])
traci.close()

Can you try this one with your setup?
Can you report your platform and your sumo version?

Best regards,
Michael

Re: [sumo-user] Feeding SUMO with Time Series data

Hi,
if your network is properly connected (meaning there are indeed more

more random trips as input.

Re: [sumo-user] Mapping of GTFS data to network error

[Michael Behrisch]

Hi,
the first warning about the tracemapper can be ignored but the second is
strange, it basically says that it either could not find data for busses
in the GTFS or no edges alllowing busses in the network and thus
generated no bus network. Since the GTFS import is quite new and all
data providers implement the standard a little bit differently, can you
share your inputs?

Re: [sumo-user] TracI fails randomly after running for quite a while

[Michael Behrisch]

Hi,
please try to isolate the error by finding the sources of randomness.
Usually SUMO delivers repeatable results even with multiple clients if
it is not set to random behavior (i.e. the option --random is not used)
and if the client scripts themselves do not use randomness.

Re: [sumo-user] Assorted errors when using threads (1 new simulation per thread)

[Michael Behrisch]

Hi,
I added now another parameter to traci.start which can prevent switching
to the new connection. It works here with your example. Please try with
a nightly build (or git pull) whether it now solves your problem if you
set switch=False in traci.start.

Best regards,
Michael

Re: [sumo-user] Assorted errors when using threads (1 new simulation per thread)

[Michael Behrisch]

Hi,
I just ran it from the command line not in an IDE. I probably won't be 
able to reproduce it if it just occurs in an IDE. Does it occur at all 
if you run from the command line (or without breakpoints)?


Best regards,
Michael

Hi Michael

Thank you for your reply

I tested again with the daily version and the errors still happen when 
putting a breakpoint (e.g., sumo_env.py l. 111)


The errors occur more frequently when using Pycharm (2020.1.5 community) 
than using vscode (1.56.0). I'm not sure why. I'm using Python 3.6 on 
Linux (Ubuntu 20.04).


Did you test with breakpoints too?

Thank you

Hi everyone

I'm having trouble using multiple simulations in different threads

The difference can be perceived by changing max_workers to 1 and 2.
"        with ThreadPoolExecutor(max_workers=len(possible_actions)) as 
executor:" (planning_only_agent.py, line 100)


[See attached example (a very simplified version of what I'm actually 
using)]


With max_workers=1, it works just fine.

With 2, it gives all sort of errors:

"bad char in struct format"
"unpack requires a buffer of [x] bytes"
A lot of times it just hangs
"Received answer 0 for command 211."


The easiest way I found to reproduce is to add a breakpoint into a 
subscribe call and hit continue several times. It is likely to crash 
when threads stop at the same command, although it occurs eventually 
without breaking points.


Tested in version 1.9.0 (specifically v1_9_0+0210-fa53508669)

Thank you in advance

Hi,
thanks for your PRs! I implemented a slightly different solution. It
would be great if you and of course all other LiSuM users could check
whether the nightly build works as expected, since I do not have the
"real thing" here.

Re: [sumo-user] randomTrips.py creates trips for invalid routes

[Michael Behrisch]

Hi,
you cannot. You either need to check your network beforehand (you can
try to use https://sumo.dlr.de/docs/Tools/Net.html#netcheckpy for that)
or increase the number of vehicles (decrease the period) and then remove
some of the generated trips auntil you reach your desired number.

Best regards,
Michael

Re: [sumo-user] there is an error in the building of sumo-1.8.0

[Michael Behrisch]

Hi,
swig4 cannot handle very long file names. So you either need to 
downgrade your swig by checking out SUMOLibraries at 
d470317335c91a9c8964e9ad828c896c3d6324d8 or disable Java bindings if you 
don't need them by setting ENABLE_JAVA_BINDINGS=OFF in the cmake call 
(or directly in the cache file). It is also fixed in the nightly build.


Best regards,
Michael

Re: [sumo-user] NETCONVERT freezes on very large networks

[Michael Behrisch]

Hi,
if it occurs only with the latest nightly build but not with 1.8 it
might as well be https://github.com/eclipse/sumo/issues/8270. It does
not freeze it just takes very long, I also noticed that with the Berlin
network.

Re: [sumo-user] [Installation] Obsolete SUMO on Debian

Hi,
I think the build should work even with gcc 4.8, so please try to find 
which package provides the missing headers. StackOverflow mentions 
build-essential as a good candidate.

Re: [sumo-user] Address already in use: Race condition between isolated executions

[Michael Behrisch]

Hi,
that looks different indeed. Such buffer problems usually indicate that
your client uses a different traci version than the server. Please check
that they are on the same version and you do not have any old versions
in your PATH/PYTHONPATH.

Re: [sumo-user] Version UNKNOWN

[Michael Behrisch]

Hi Jose,
no it is not, but usually it should be set automatically. Please check
whether tools/build/version.py can be executed and look into the build
log for something like

Generating version.h
generating /home/delphi/gcc/sumo/build/gcc4_64/src/version.h from
revision in /home/delphi/gcc/sumo/.git/index

Are you using a download or a git clone?

Hi,
it depends a little on the system you are on and which way of "direct"
installation you choose. For Linux the functionality and licensing
prerequisites of the different packages (rpm/deb) differ slightly
depending of the available packages, see here:
https://sumo.dlr.de/docs/Downloads.php#note_on_licensing
The python package contains the plain SUMO (without extras) but it comes
with its own libraries, so you will not benefit from updates of
libraries on your system but also do not have the risk of breaking
things by updating other libraries. Furthermore the python package is
easier to be installed as a normal user and by using virtual
environments it is easy to have several parallel versions of sumo
installed. On the other hand it is not as well integrated into the
system, e.g. the binaries are in a different location than usual, which
makes it less suited for multi-user installations. The libraries and
sumo can also not benefit from optimizations the compiling process
applies during packaging.

So in short: If you have admin rights, you don't need multiple parallel
SUMO versions, and there is a package for your system use that one.

For Windows the contents of the SUMO installer and the python package
are identical, it is just the system integration that differs. The
python package does not set SUMO_HOME or adapt the PATH (although this
may be taken care of by pip or your python installation) and you don't
can double click sumocfg files to start. Concerning user installation
and virtual environments the Linux remarks apply here as well.

Best regards,
Michael

Re: [sumo-user] SUMO 1.8.0 released

[Michael Behrisch]

Hi Karl,
Lisum needs Java11 now and we do not want to use different Java versions
for our components. But if you recompile yourself this should not be a
problem and it maybe even possible to use it with Java8 as is.

Concerning the interface: We did not do all the type conversions we did
for Python for Java yet because we do not have a project or active user
which/who uses them and not even a good test suite. Patches are welcome :-)

Best regards,
Michael

Re: [sumo-user] Creating a highway exit/entry scenario

[Michael Behrisch]

Hi Branka,
the generated plain file contains only one edge which has three lanes so
everything is fine.
Your definition of the third node is fine, you just need to split your
edge and let one part run from gneJ1 to gneJ3 and one from gneJ3 to
gneJ2. (You can achieve this in netedit as well by doing a right click
on the edge and select "split here".) Then add another node J4 and an
edge from gneJ3 to gneJ4.

Best regards,
Michael

Hi Jose,
the easiest way is probably to edit the CMakeCache.txt and adapt the

Re: [sumo-user] Why does vehicle start to use fuel when it is still standing on the lane?

[Michael Behrisch]

No, currently the model assumes zero emissions for coasting (negative
acceleration) but not for standing. But this is of course a model
assumption which is questionable for modern vehicles which switch off
the engine at every junction. So it basically depends on your
assumptions about the vehicle (fleet) you want to model.

Best regards,
Michael

Re: [sumo-user] [EXTERNAL] Re: Edge-based Traffic Measures (meandata) fail to detect left vehicle

[Michael Behrisch]

Hi,
there are some problems with the scenario but I think the most obviuos
is that there are very short edges around the junctions which have a
length which is larger than the visible length. I did not verify this in
detail yet but this could lead to vehicles being visually on the edge
when they are in fact not.

Re: [sumo-user] Error compiling sumo master

[Michael Behrisch]

Hi,
I think your version of gl2ps may be too old. The function it complains
about has been introduced in 1.3.8 (7 years ago).
If you don't need vector graphic screenshots, then you can just disable
it (for instance by uninstalling the gl2ps-devel package and running
cmake again).

Michael

Re: [sumo-user] Why does vehicle start to use fuel when it is still standing on the lane?

[Michael Behrisch]

Hi Piotr,
thanks for the scenario. The behavior has two different reasons, which
are tracked in the tickets https://github.com/eclipse/sumo/issues/7733
and https://github.com/eclipse/sumo/issues/7734
The main thing is that the internal acceleration value is still less
than 0 even if the printed velocity is already 0 (due to rounding) for
the first ten seconds of the stop. This makes the emission model assume
the vehicle is coasting.

Best regards and thanks for reporting,
Michael

Re: [sumo-user] Edge-based Traffic Measures (meandata) fail to detect left vehicle

Hi Xun,
is this an off by one error (i.e. the vehicle is detected in the next

the interval. If not, please try to send your scenario for further
inspection.

Re: [sumo-user] Creating a highway exit/entry scenario

Hi Branka,
please do not modify the net directly. If you want to take your net as a

Hi Max,
in which way are the x,y coordinates wrong? Can you send your input files?
When converting from x,y to lon lat you need to leave out the last

Hi,
concerning the missing vehicle, please check the log for any error

Concerning the netedit version, I would also assume that you have some

Does netedit show the right version when you start it from the start

Re: [sumo-user] Cannot run state saved from previous version

[Michael Behrisch]

Hi Abdullah,
states are not meant for long term saving, so you cannot use a 1.3.1
state with sumo 1.7.0. Depending on the size there is a small chance you
might be able to convert it by hand but it is not something which is
easily done.
Usually new states contain more values which you will not be able to
recreate without rerunning the simulation.

Best regards,
Michael

[Michael Behrisch]

Hi Xun,
I do not fully understand wha you are trying to achieve. The sources and
destinations are given and you want to assign them randomly to each
other? Or do you want random volumes between fixed pairs? The routes
should be shortest paths or the vehicles should turn randomly (according
to given probabilities) in the network but eventually reach a given
destination?

Re: [sumo-user] How to make car following less safe?

[Michael Behrisch]

Hi Jan,
the behavior you see is an artifact of conservative estimates in the
sumo code, see the comments here:
https://github.com/eclipse/sumo/blob/master/src/microsim/cfmodels/MSCFModel.cpp#L855
On the other hand there is https://github.com/eclipse/sumo/issues/4134
which seems to point in the opposite direction.

You could try the DriverState https://sumo.dlr.de/docs/Driver_State.html
to modify driver perception. This sdoes not apply to the accelerations
so it should not be affected by this estimation.

Best regards,
Michael

Re: [sumo-user] Different vehicle's distance results for different step-lenght

[Michael Behrisch]

Always expect the unexpected ;-)
Seriously, if we knew them, we would fix or at least track them but a 
good overview of known things is maybe: 
https://github.com/eclipse/sumo/issues?q=is%3Aissue+is%3Aopen+ballistic


In general there are places in the code especially in detectors which 
try to interpolate the vehicle position at a fraction of a step from 
speed and step length especially in detectors. Many of them have been 
adapted but not all.

Re: [sumo-user] Different vehicle's distance results for different step-lenght

[Michael Behrisch]

Hi,
unfortunately your assumptions on the calculations are wrong. Unless you 
activate --step-method.ballistic sumo will first calculate the new speed

v = v0 + a*dt and then assume this speed for the whole step
s = s0 + v*dt.

Best regards,
Michael

Hi,

How does distance is calculated for vehicle. I notice that for the same
configuration except step-lenght, I got different results.
I attached sumo xml files. When vehicle is created i set its speed to
maximum.

sumo version 1.7.0
These are the results for my test:

step-length 0.005
[0] speed:0, distance:0
[1] speed:2.6, distance:1.3065
[2] speed:5.2, distance:5.213
[3] speed:7.8, distance:11.7195
[4] speed:10.4, distance:20.826

step-length 0.05
[0] speed:0, distance:0
[1] speed:2.6, distance:1.365
[2] speed:5.2, distance:5.33
[3] speed:7.8, distance:11.895
[4] speed:10.4, distance:21.06

step-length 0.1
[0] speed:0, distance:0
[1] speed:2.6, distance:1.43
[2] speed:5.2, distance:5.46
[3] speed:7.8, distance:12.09
[4] speed:10.4, distance:21.32

I assume that speed and distance are calculated by V = V0 + at and s = s0 +
V0*t + a*t^2/2 equations.
a = 2.6
v(0) = 0, s(0) = 0 s(t) = at^2/2
v(1) = 2.6 (ok), s(1) = 2.6 / 2 = 1.3 (even for step-length = 0.005 the
result is different
v(2) = 5.2 (ok), s(2) = 2.6 * 4 / 2 = 5.2 (not ok)

Re: [sumo-user] SUMO dataset availability of long duration

[Michael Behrisch]

Hi,
if you really need different mobility patterns (more shopping and 
leisure activities on weekends and more commutes on weekdays) you are 
probably out of luck. What we usually do is simple scaling by a constant 
factor for weekends and keeping weekdays identically.

Hello everyone,
   I have been looking for a dataset of an urban area vehicular 
traffic of long duration as well as sufficient time resolution.


I know there are pretty good datasets available such as LuST, MoST, 
Cologne, Bologna, etc. But they are of short duration, mostly 24hrs. I 
want a more extended time where daily and weekly traffic pattern 
repetition (seasonality) is observable. My actual target is to make some 
decisions based on this repetitive pattern.


I also know about the PEMS dataset (California Department of 
Transportation) of such longer duration data. But mostly, they are just 
counts of some metrics (e.g., vehicle count at a fixed point), not of 
high resolution—neither SUMO data.


Is there any dataset available where both can be found? I don't need a 
large area dataset, just a small area with visible seasonality will do. 
Can anyone suggest me what to do?


Thanks.

I cannot explain this behavior. Can you share your scenario?

Thanks, I understand now.

Two more question about fuel used:
1.
motion.png

moment_fuel.png

fuel.png

I created simulation with tls intersection. I draw a charts for one vehicle.
On motion.png chart (see attachment) you can see vehicle's speed in
simulation time. On other two charts you can see moment fuel and sum fuel
used by vehicle from the begining of motion. Why does vehicle start to use
fuel when it is still standing on the lane (speed is equal 0). See 127s of x
axis in all charts.
It is unintuitive for me. Could you explain?

2. The length of gneE0_0 lane is 191m. Vehicle used about 4.5 ml of fuel. It
is about 2.4l / 100 km. It seems to be very small fuel usage for cars. What
do you think about this value?

This release brings you a load of new traci functions and even new 
domains.

There are many more features and fixes in this release and the most
important ones are listed below.
For a full list of changes, as always see 
http://sumo.dlr.de/wiki/ChangeLog


=== Enhancements ===
- Simulation
  - Added option **--person-summary-output** which causes statistics on
person numbers and their travel modes to be written in every simulation
step.
  - Option **--scale** now also applies to persons.
  - Taxi pickup and drop-off location can now be restricted to public
transport stops
  - Added new taxi dispatch algorithm 'routeExtension'.

- netconvert
  - Added new node attribute 'tlLayout' to configure signal plan layout 
per

node.
  - Added new traffic light layout 'alternateOneWay' to model work 
zones

where each direction uses the interior of a joined traffic light
exclusively.
  - Added option --roundabouts.visibility-distance to set the default
visibility distance when entering a roundabout. The new default is 9 
meters

which leads to smoother flow.

- netedit
  - Elements can now be marked as 'front element' (F11) to facilitate
working with overlapped objects in move mode and traffic light mode.
  - Added junction context-menu option 'convert to roundabout'.
  - Vehicles and Flows with their own (unnamed) route can now be 
created

directly.
  - LaneAreaDetectors with multiple lanes can now be created.

- sumo-gui
  - A color legend for vehicle colors can now be enabled via the 
'Legend'

tab.
  - Vehicles can now be stopped and stops can be aborted via context 
menu.


- TraCI
  - Added new function 'simulation.loadState' for quick-loading a saved
simulation state.
  - Added new function 'vehicle.getStops'. This can be used to retrieve 
the

next or last n stops. The method returns a list of stop objects with
extended attributes.
  - The python client now supports the optional argument 'traceFile' in
function traci.start which records all traci commands to the given file
(also works for libsumo.start). The optional boolean argument
'traceGetters' can be used to switch off tracing of data retrieval
functions.
  - Added function 'vehicle.replaceStop' which replaces the upcoming 
stop

with the given index and automatically adapts the route to the new stop
edge.
  - Added function 'vehicle.getFollower' which works like getLeader but
looks backwards.
  - Function 'person.moveToXY' is now officially supported whenever a
person is walking or stopped. It can be used to move a person to an
arbitrary place and will update the route accordingly.
  - Added functionality for retrieving lane, position and stopped 
vehicles

for traci domains 'busstop', 'parkingarea', 'chargingstation' and
'overheadwire'.
  - Added functions 'routeprobe.sampleLastRouteID' and
'traci.routeprobe.sampleCurrentRouteID'.
  - Added function 'gui.track' which can be used to track persons.
  - Added functions 'gui.isSelected' and 'gui.toggleSelection' to 
retrieve

and modify selection status.

- Tools
  - Added new tool computeCoordination.py to compute the fraction of
delayed vehicles along a defined corridor.
  - Added new tool net2geojson for converting a .net.xml file into 
GeoJSON

format.
  - Added new tool addStopDelay.py to add random stop delays to a route
file.

=== Bugfixes ===

- Simulation
  - Fixed invalid amount of charged energy in subsecond simulation when
using battery device.
  - Fixed invalid error when setting vehicle stop.
  - Fixed bugs that were causing vehicle collisions.
  - Fixed deadlock on intersection.
  - Fixed bugs where pedestrians would step onto the road when it 
wasn't

safe.
  - Fixed various sublane model issues
  - CarFollowModel fixes: 'KraussPS' no longer stalls at steep 
inclines,

Multiple fixes to 'W99'
  - Person rides with a specified arrivalPos no longer exit their 
vehicle

prematurely.
  - Various fixes to waypoints
  - Various railway fixes related to collisions and emergency braking
  - Vehicles no longer get stuck when setting 'maxSpeedLatStanding=0'.

- netconvert
  - Fixed missing busStops when importing public transport lines from 
OSM.

  - Fixed invalid error when patching network with netdiff patches.
  - Fixed invalid keepClear state for intersections without 
cross-traffic.


- netedit
  - Fixed bugs that were causing crashes
  - Fixed bug where all passenger lanes changed their permissions when
adding a sidewalk.
  - Fixed bug that caused inconsistent output when modifying the 
traffic

light index of connections.

- TraCI
  - Fixed memory leaks when using

Hi,

successfully,

Then you should probably try to contact the maintainer of that branch.
It seems to be a two year old fork. Maybe it branched at a point where
sumo was not able to handle the new proj API. You could also try to
install an older version of proj.

Michael

Re: [sumo-user] Installation of SUMO-1.6.0 Latest Release on Linux failure

[Michael Behrisch]

Hi,
try to give a fixed number after the -j such as make -j8.
The "make -j$(nproc)" below should limit the number of parallel
processes to the number of processors in your machine. If you just start
"make -j", the process will start as many parallel processes as it can,
resulting in overloading your main memory.

Best regards,
Michael

Re: [sumo-user] Previous stage output not available in TraCI

[Michael Behrisch]

Hi,
I am pretty sure there is some old version of sumolib on your system
which python is finding. Nevertheless I updated version.py now in a way
that it will at least continue in this case. Please retry after a git
pull or with a fresh download of the nightly zip tomorrow.

Best regards,
Michael

Re: [sumo-user] modified the output file of SUMO

[Michael Behrisch]

Hi Jane,
there is no way to do this with sumo alone. Depending on the operating
system you use you could write the data to a socket or a named pipe and
read and filter it from there without an intermediate file. The
xml2csv.py might be an option as well.

Best regards,
Michael

Re: [sumo-user] Emissions for "PC_Alternative"

[Michael Behrisch]

Hi,
PC_Alternative is somehow a collection of everything which is not Diesel 
or Gasoline,
so Biofuels, LPG, Hybrids, Hydrogen Fuel Cells and everything else you 
can think of.
The results here are probably not very transferable, since they were 
calculated with one

special fleet in mind and mix very different things.

Best regards,
Michael

Hello,

I wanted to know what emissions are calculated for the emission class
"PC_Alternative".
How does it differ from the other Diesel or Gasoline emission classes?

Thanks!
