[sumo-user] Modelling Public Transport Line (or fixed Route)

[Tripplanner Mumbai]

Hello,

I am confused about the implementation of public transport route inside
SUMO.

As per standards, a public transport route (sometimes known as a line) has
a fixed sequence of stops which it has to cover, and a frequency which
means the number of times that route must be served at these stops.

In SUMO, we have a  tag, but I think it is used for deciding a path
not a public transport route (or line). On the other hand, a route is
modelled through  tag using an attribute "line". Well, such
modelling is discouraging as each time we have to repeat the sequence of
stops and related edges, as given below of two instances repeating the same
information unnecessarily.

Instance 1:









Instance 2:









Furthermore, I would like to know about implementing frequency assignment
to a public transport route (or line). Could anyone clarify my doubts or
redirect me to a correct thread.

thanks and regards,
Dillip Rout

Re: [sumo-user] Modelling Public Transport Line (or fixed Route)

[Tripplanner Mumbai]

@Mirko @Jakob: Thank you so much for coming to my rescue. Please clarify if
I have interpreted it the flows correctly.



Does it indicate that a public transport line (or route) with id named
"bus" whose sequence of stops are defined by route named "busRoute".
The frequency of this line is 300 seconds or 5 minutes per hour, that
is in every 5 minutes there will be one vehicle for this line.
However, the service stops at 801 seconds from the simulation time, it
means that there will be only two vehicles started for this line.

@Mirko: osmWebWizard is indeed a great tool, thanks.

Re: [sumo-user] Generate ticket data while simulating public transit line (route)

[Tripplanner Mumbai]

As per the discussion, I tried to extract the stage information using TraCI
and combine the log files to generate the ticket data. However, for some of
the cases, I get fatal errors as follows.

File "/home/dhrien/Documents/sumos/Bologna/acosta_persontrips/demo.py",
line 86, in run  prevStage = traci.person.getStage(peopleIDs[i],-1)
File "/usr/share/sumo/tools/traci/_person.py", line 192, in getStage
tc.VAR_STAGE, personID))
File "/usr/share/sumo/tools/traci/connection.py", line 158, in _checkResult
result = self._sendExact()
File "/usr/share/sumo/tools/traci/connection.py", line 101, in _sendExact
raise FatalTraCIError("connection closed by SUMO")
FatalTraCIError: connection closed by SUMO

The above error is due the following code segment written inside run method
of TraCI program.
currStage = traci.person.getStage(peopleIDs[i])
if currStage.type == 3: #record only if driving or riding

try:
prevStage = traci.person.getStage(peopleIDs[i],-1)
except FatalTraCIError:
print("Previous Stage Error for Person",peopleIDs[i])
continue

Note that previous stage is retrieved only if a person is boarded into a
vehicle. Also, l am trying handle the exception but the program stops.
Further, I do check if previous stage is null (None) and then operate but
unfortunately nothing works at this moment.

Please suggest.

thanks and regards,
Dillip Rout

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

[Tripplanner Mumbai]

Hello Jakob,
I tried the version was updated on August 16 and found the same errors.
Then, as per your instructions, I ran "make clean" followed by "make
VERBOSE=1" inside cmake-build folder. Again, the ended in errors.
The output of "make VERBOSE=1" instruction is attached herewith. Note that
I am using Ubuntu 18.04 as operating system.

Yes, the latest version works fine for retrieving the previous stage. It is
especially helpful when two consecutive rides are there.

Re: [sumo-user] Generate ticket data while simulating public transit line (route)

[Tripplanner Mumbai]

Hi Jackob,
I want to point out to your comments at github link- "*when calling
traci.person.getNextStage(personID, nextStageIndex) with a negative index,
if the vehicle has already left the simulation, traci crashes when trying
access the vehicle type*".

You may be right that it happened due to the fact the vehicle has left.
However, the error is due to accessing the previous stage and the
properties of previous stage (not the vehicle type or ID of the current
stage).

I am attaching a modified TraCI file for your reference. It raises
exception on line 66, and a customized error is as follows:
Error in Previous Stage retrieval, so, skip this personID: 2229
Interestingly, when I followed the person in persontrip.rou.xml, I found
the following information.
   








It means that the error occurred when 2229 waiting for his second ride
(lines="89"), and I am trying to get the previous stage information, his
first ride (lines="14"), possibly, the corresponding vehicle of his first
ride has left the simulation. Hence, we are unable to fetch the previous
stage information.

Roughly, I guess that this situation might arise whenever there is a
consecutive ride (public transit lines) for a passengers, in his plan.

thanks and regards,
Dillip Rout

[sumo-user] Computing distance and travel time from a bus stop to another bus stop

[Tripplanner Mumbai]

Hello,
I have a network and all its properties are defined. I am getting all
needed output such as stop information, trip information, person
information, etc.

However, I would like to know how to calculate or find out the distance and
travel time (as per definition). For example, I have a transit line (or
public transport route) as follows.





Now, if I wanted to find out the distance and travel time from busStop#35
to busStop#36. TraCI code is preferable to obtain these requirements.

thanks and regards,

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

[Tripplanner Mumbai]

Finally, I installed SUMO through the command line (sudo apt install SUMO)
and tried to get the previous stage data through TraCI but again the same
issues persist here, i.e., it goes for exception and the program stops.
It is a prolonged question which is yet to be answered by anyone, will I
get an answer for it?

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

[Tripplanner Mumbai]

Hello Jakob,
Thank you for taking so much of effort to correct the null pointer.

I downloaded the latest version of August 5 and followed the following
steps for installing SUMO on my Ubuntu 18.04 machine.

   1.

   sudo apt-get install cmake python g++ libxerces-c-dev libfox-1.6-dev
   libgdal-dev libproj-dev libgl2ps-dev swig
   2.

   export SUMO_HOME="$PWD/sumo"
   3.

   sudo mkdir sumo/build/cmake-build && cd sumo/build/cmake-build
   4.

   sudo cmake ../..
   5.

   sudo make -j$(grep -c ^processor /proc/cpuinfo)
   6.

   sudo make install


However,Step-5 resulted in the following error while installation:
[  2%] Linking CXX static library libutils_xml.a
[  2%] Built target utils_xml
Makefile:140: recipe for target 'all' failed
make: *** [all] Error 2

Kindly look into the issue.

with best regards,
Dillip Rout

Re: [sumo-user] stop output and trip output do not match

[Tripplanner Mumbai]

Hello,
I ran it again using the TraCI program and the log says the following.
   Persons: [Inserted: 9000, Running: 28, Jammed: 167]
Possibly, you are pointing out to Running: 28 which is the discrepancy.

Furthermore, I share the following counts of rides got from the execution:
  2334 trip-output
  2341 stop-output
  2341 TraCI program log

Clearly, the ride statistics from the simulation matches the trip-output
count:
  Ride Statistics (avg of 2334 rides): [WaitingTime: 205.01,
RouteLength: 505.21, Duration: 100.75, Bus: 2334]

However, the ride count is note balanced as per your recommendation,
i.e., *trip-output
== stop-output - running*. On the other hand, stop-output == TraCI count,
which is only about the completed rides (not the entire trips).
Looks like I have to extract some more information from TraCI to get the
desired result. Meanwhile, if you have some more clarification and
suggestions, please let me know.

thanks and regards,
Dillip Rout

Re: [sumo-user] stop output and trip output do not match

[Tripplanner Mumbai]

Hello Jakob,
My apologies for misinterpreting your statements, thanks for your
clarification. Yes, the analysis is true there are multiple persons with
single or double riding.

Now, I am trying to extract the trip information using TraCI, but not
successful right now. In Particular, I was trying to extract the following
information from the previous stage.

* print("previous
stage","type",prevStage.type,"dest",prevStage.destStop,"travel time",
prevStage.travelTime, "distance",prevStage.length,"depart  time",
prevStage.depart)*

Unfortunately, the output does not contain all the required information, as
shown below.
 *previous stage type 3 dest busStop#12 travel time -1.0 distance
672.437702712895 depart time -0.001*
As seen, travel time and depart time are negative, it is hard to interpret.
I guess the distance shown is the distance of the ride covered in previous
stage of the person. Further, depart time is a must field for my objective.

Could you please provide some insights so that I can get the values of all
fields of previous stage?

thanks and regards,
Dillip Rout

Re: [sumo-user] Uninstalling SUMO

[Tripplanner Mumbai]

Hello,
I tried to execute the first command for uninstalling as per given
instructions in
https://sumo.dlr.de/docs/Installing/Linux_Build.html#uninstalling

   sudo xargs rm < install_manifest.txt

However, I failed to find  install_manifest.txt file. I searched the
entire $SUMO_HOME directory but it does not exist. Mention that I had
installed
the latest development version which was updated on June 25.

Kinldy, recheck the development version if it carries install_manifest.txt file.

thanks and regards,

Re: [sumo-user] Uninstalling SUMO

[Tripplanner Mumbai]

Hello Herald,

I just installed the latest development version which was updated on
July 5 (205 MB file) for Ubuntu 18.04.

I followed your instructions, also searched it manually, yet this
install_manifest.txt files not exists in my installation. I guess that
it may for particular

type of installation. The developer may have some insights.

thanks and regards,

Re: [sumo-user] Uninstalling SUMO

[Tripplanner Mumbai]

Hi Herald,

Thanks for reverting back.

I downloaded the latest development version, updated on July 5 which is
available at
https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version.
Then. I followed the below instructions to install SUMO into my system
(while at my /home/dillip directory on my Ubuntu 18.04 system).

   1.

   sudo apt-get install cmake python g++ libxerces-c-dev libfox-1.6-dev
   libgdal-dev libproj-dev libgl2ps-dev swig
   2.

   export SUMO_HOME="$PWD/sumo"
   3.

   sudo mkdir sumo/build/cmake-build && cd sumo/build/cmake-build
   4.

   sudo cmake ../..
   5.

   sudo make -j$(grep -c ^processor /proc/cpuinfo)

After installation I checked all directories and also followed your
instructions to find install_manifest.txt file, however, I did not find it.
Now, could you please point out where the issue is.

thanks and regards,
Dillip Rout

Re: [sumo-user] Uninstalling SUMO

[Tripplanner Mumbai]

Hi Harald,
Thank you so much for pointing out that I was missing "make install" step.
Yesterday, I added this step and installed the new version updated on July
25. Also, i have changed the SUMO_HOME as instructed and updated this in my
.bash_profile. The sumo and TraCI are working from the command line.
However, when I am trying to run the TraCI program from Spyder3 (python
IDE), it throws an error that it is unable to connect to TraCI through X
port, where X refers to various port numbers. Could you please suggest, how
to resolve this issue? I would always prefer to run TraCI from Spyder3 as
it suppresses the SUMO warnings and outputs the program related prints and
errors.
thanks and regards,
Dillip Rout

Hello Harald,
I resolved the below issue by uninstalling and reinstalling Spyder3.

*when I am trying to run the TraCI program from Spyder3 (python IDE), it
throws an error that it is unable to connect to TraCI through X port, where
X refers to various port numbers. *
Thanks for your help.

Hello,
@Harald, thanks for your tips to improve exceptions and dumping.

@Jakob,  it is suspected that the newer version (updated on July 25) is
having issues in retrieving the previous stage attributes, kindly look into
it and fix it.

Re: [sumo-user] Traffic simulation for a month

[Tripplanner Mumbai]

Hello,
Let us assume that a machine with sufficient computing power is available.

Now, there are two bare minimum input files for the simulation (1)
city.net.xml - contains the structure of the underlying network  (2)
city.rou.xml - contains the vehicles and respective routes (paths) and
possibly schedule.

Do you mean that we should have separate files of (1) and (2) for each day
of the month?

thanks and regards,
Dillip Rout

[sumo-user] Modeling of speed, congestion and flow in SUMO

[Tripplanner Mumbai]

Hello,
I am curious to know how SUMO models the speed of a road segment at a given
period. Furthermore, the congestion computation is critical, so, what is
the default model to calculate the congestion rate in SUMO?
It will be really useful if some links to documentation and articles are
provided.

[sumo-user] Traffic simulation for a month

[Tripplanner Mumbai]

Hello,

SUMO is pretty nice in simulating traffic and getting the relevant
parameters given a scenario including traffic and network. However, these
simulations are only for a short period of time or a day.
What more is required to simulate the traffic movement for a month? Note
that the traffic pattern differs from day to day, e.g., weekends will have
less traffic as compared to weekdays. Hence, we will get different kinds of
simulations on weekends. Mostly, I am looking to extract a network from OSM
through the interface provided by SUMO.

[sumo-user] Defining depot in a SUMO network

[Tripplanner Mumbai]

Hello,

I need to define a bus depot so that the buses can rest at the depot and
not create congestion on the road if those are parked on the bus stops.
Nonetheless, I could not find a tag/field indicating depot.

Is the depot defined through a parking area? If yes then how to define the
capacity of that parking space? Say, I would like to have a parking area
which can accommodate 10 buses.

thanks and regards,
Dillip Rout

Re: [sumo-user] repeating public transit routes

[Tripplanner Mumbai]

Hello,
I think there must be a simpler way of re-routing using the attribute *line*
of  tag. As per definition, we can set a new line attribute on the
vehicles at this particular stop, it will be triggered automatically.
Also, I observe that there is a *tripId* attribute for  tag. Can it
be used to count or record various trips of a particular vehicle?
thanks and regards,
Dillip Rout

Re: [sumo-user] Some ideas and proposals for repeated routes

[Tripplanner Mumbai]

Hello Jakob,

I understand your concern regarding the change or addition of new classes.
It is absolutely fine till things are working, especially with backward
compatibility. A splendid work has been done by you and your team, no
doubts. We are lucky to have your advice, time to time, majority of the
queries are sorted out within a day.

It is pretty nice to see renaming of the period attribute of route to
cycleTime (also known as round trip time). It will be adopted and
appreciated soon by the users. Just a query regarding the coexistence of
*end* and *number* attributes in flow (see below). As per the current
verion, both cannot be used simultaneously, is it contradictory?


Kudos to your team again for such evolving development of SUMO.

thanks and regards,
Dillip Rout

Re: [sumo-user] repeating public transit routes

[Tripplanner Mumbai]

Hello Jakob,
"A  defines a place and direction for stopping, (because it is on
a specific lane and lanes are directional)".

Yes, I missed the direction aspect of a bus stop. In my example, my up and
down stops are the same, so I devised the route with a relevant set of
edges for having a cyclic (upstream and downstream).
As you pointed out, I have to learn a lot about the network file and its
properties. Also, I need to define depots so that layover time can be
defined at depots not at bus stops.
Thanks a lot, I am moving ahead with these inputs, really helpful.

with best regards,
Dillip Rout

Re: [sumo-user] repeating public transit routes

[Tripplanner Mumbai]

@Jakob,
*Rerouting:* Yes, I am interested in having two routes for a single public
transit line. Any vehicle assigned to this line will swap between the
routes once it reaches the end point at one direction or a depot. I will
make an attempt soo, will inform about the progress, and troubles if any.

*TripId:* I just added tripId information to  of a route. Yes, it is
getting printed in stop-output by default. However, it is not changed if a
vehicle is having multiple trips according to route definition: repeat,
cycleTime, period, number, etc. If this is what the tripId actually does
then it is doing the job of trip direction not tripId. It is due to the
fact that tripId supposed to be incremented after each trip ends and new
trip begins for a vehicle.

Hello,
Again, I tried this with the latest development version of SUMO which was
updated on June 25, 2020. However, the same issue continues, *i.e.*, the
number of boarded and alighted persons in stop output is more than the
number of records in trip output.
Kindly, look into it at earliest.

[sumo-user] Uninstalling SUMO

[Tripplanner Mumbai]

Hello,

Recently, I installed a sumo (v1_6_0+0676-d20520c106) by the instructions
(cloning and installing) given in the page (on my Ubuntu 18.04)
https://sumo.dlr.de/docs/Installing/Linux_Build.html.

Now, I want to uninstall it and install the latest development.
However, when I tried the command: *sudo apt remove --purge sumo*
It shows that no SUMO is installed. Nonetheless, when I typed the
command: *sumo
--version*, it shows me the version of the SUMO.

Can anyone suggest how to uninstall my current version, which was build
through cmake and all?

thanks and regards,

Re: [sumo-user] repeating public transit routes

[Tripplanner Mumbai]

Hello Jakob,
I tried something similar to your example:






It is observed that vehicles assigned to such a line (public transit route)
are indeed taking multiple trips as per the definition and the relative
time values are maintained. Each of these assigned vehicles always run from
start to end terminal, in this example, stop lane="SC_0" is always the
start and one direction. However, none of the assigned vehicles are
restarting from the end terminal to the start terminal, in this example,
stop lane="CN_0" is never a start.

All I am trying to point out is that an assigned vehicle of a line starts
at one terminal and goes to the other terminal (upstream journey). Then,
the vehicle starts from the other terminal and comes back to start
(downstream journey). Nevertheless, the simulation in SUMO always logs only
the upstream journey although the vehicle is actually making the downstream
journey as well.

I extended your example (bold) to force the vehicle of the line to halt at
downstream journey too:



**


However, it did not produce the desired result.

I request you to suggest something by which both upstream and downstream
journey of each vehicle of the route will be captured.

thanks and regards,
Dillip Rout

Re: [sumo-user] Defining depot in a SUMO network

[Tripplanner Mumbai]

Hello,
If I set  attribute parking=true, then is it going to be recorded in
stop-output? What if I implement a parking area for the depot, is it going
to be included in stop-output?

Re: [sumo-user] Uninstalling SUMO

@Michael,
I noticed that the uninstalling instruction is updated.
I am currently using the latest development version (updated on June 15,
2020). I fell to find manifest.txt in my installed sumo directory. Is
manifest.txt added recently to the build files?

Re: [sumo-user] Some ideas and proposals for repeated routes

[Tripplanner Mumbai]

Hello Herald,
Thanks for coming up with a proposal.
In my opinion, the word route is ambiguous since it is used for defining a
path as well as a public transit line (or route). Hence,  a new class named
line or ptLine should be formed. This class will contain all the properties
of a public transit line (or route), may be some of those will be optional.
Broadly, this class should combine route, flow, trip, etc.
I would be happy to share the thoughts.
thanks and regards,
Dillip Rout

Re: [sumo-user] repeating public transit routes

[Tripplanner Mumbai]

Hello Jakob,
Thank you for your example, I tried to imitate it and it worked.
Actually, my intuition was right, but I struggled in understanding the
network properties. For instance, a connection from an edge to the same
edge is not trivial, look at the below example. Just notice the bold edges
which are extra, my actual route ends at 22.







If I remove the edges in bold, then the simulation throws an error that
there is no connection from 22 to 22. Then, I tried to insert one
artificial connection in my network file but it was not accepted and the
simulation stopped due to an error in the network.

The issue in defining such a route is that the travel time or round trip
time of a public transit line (or route) is not maintained well, some void
time is unnecessarily used. It may result in additional waiting time,
and/or unsatisfied demand.
Kindly, suggest if you have any sort of remedy for it.

Thank you again for your support and examples.

with best regards,
Dillip Rout

[sumo-user] Extracting bus stops from a set of edges or path

[Tripplanner Mumbai]

Hello,
I have a path (route) which is defined as a sequence of edges. For example,
a set of edges is - edges="133 31 115 110 185 92 90 m91 88 187 190 77[0]
53[1][0] 53[1][1][0] 77[1][0] 77[1][1]". Now, how can I derive the set of
bus stops corresponding to this path. I mean all the bus stops which are on
this path, i.e., linked to any of the edges.
Assume that the scenario exists and working correctly.

Re: [sumo-user] Computing distance and travel time from a bus stop to another bus stop

[Tripplanner Mumbai]

Hello,
I am using the latest development version of SUMO (
https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version).
However, I found the documentation part (
https://sumo.dlr.de/daily/pydoc/traci._simulation.html) that the signature
of findRoute is this:

*findRoute*(self, fromEdge, toEdge, vType=''", depart=-1.0, routingMode=0)

The same signature I got in my local machine where I have installed the
latest development version. Note that there is no input
for the lanes as you mentioned. Please clarify.

Hello,

traci.busstop.getLaneID("busStop#35") did not work since there is no class
in "busstop" in my installed version, you may verify it from the attachment
which is the list of classes available in my local machine. Note that I am
using the latest development version of SUMO (
https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version).

However, class "busstop" is available in online documentation (

and let me know.

then I could have unable to find anything. Please see the attachment of

Hello,

I just checked the current version which is updated on June 8. I found that
the class "busstop" is available in it. Looks like I have to uninstall mine
(updated from May) and again reinstall the new one.

Re: [sumo-user] repeating public transit routes

[Tripplanner Mumbai]

Hello Jajob,
As I believe, the following line of code is responsible for dispatching or
starting vehicles. For example, the first vehicle starts at 1 sec and the
second starts at 201. There could be at most two vehicles since the flow
ends at 211 sec.


If my above assumption is correct, then what is the need of adding period
inside route again, it is confusing. Also, note that the period is
mentioned as 100 in this case.
 
Please clarify.
thanks and regards,
Dillip Rout

Re: [sumo-user] repeating public transit routes

[Tripplanner Mumbai]

Hello,
As per the documentation (
https://sumo.dlr.de/docs/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#repeated_routes),
repeat is similar to frequency, am I correct?.
Or, the frequency is similar to vehsPerHour defined in flow (
https://sumo.dlr.de/docs/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#repeated_vehicles_flows
)
For any public transit route or line, the fleet size is fixed, those
vehicles make to and fro motion through the designated stops in various
trips.
Please let me know,
thank you,

Re: [sumo-user] repeating public transit routes

[Tripplanner Mumbai]

Hello,
I have the same issue, that is, tried to simulate bus service. For a line
(or public transit route), several vehicles (fleet) repeatedly make many
trips according to headway (period in SUMO) or frequency. As per the
suggestions @Jackob, I tried the following.
















 


However, it resulted in (i) infinite loop, simulated did not end (ii) no
lines or vehicles are repeated as per the output files.
I am also waiting to see a solution to it.

[sumo-user] Loading the scenario or simulation using TraCI

[Tripplanner Mumbai]

Hello,
I was trying to only load (not start the simulation) the simulation network
or scenario using TraCI, particularly the following code (ref-
https://sumo.dlr.de/daily/pydoc/traci.main.html).

try:
traci.load(['-c', 'run.sumo.cfg']) #only loads the simulation or
scenario, not starts
print("TraCI program loads the network successfully")
except:
print("TraCI program is unable to load the network")

Unfortunately, it always prints the exception part, that is, the program
fails to load the network.

Can anyone let me know how to only load the network, not start is through
TraCI?

Dillip Rout

Re: [sumo-user] Loading the scenario or simulation using TraCI

[Tripplanner Mumbai]

With respect to TraCI, I thought that the following line of code loads and
starts the simulation:
   traci.start([sumoBinary, "-c", "run.sumo.cfg"])
However, now I realize that this loads and starts the basic (or zeroth)
step. The actual step by step simulation is executed by the following line
of code:
  stepCount=traci.simulationStep() #capture the steps of
simulation, one step at a time

Please correct me if I am wrong, further comment please.

Re: [sumo-user] Traffic simulation for a month

Hello,
Yes, segregating the routes data as per suggestion will be helpful.
However, I am clueless about the underlying theory of simulation in SUMO.
That is, how it simulates each day differently (given the network file and
separate routes files). What are the attributes it takes into account to
imitate the real-time scenario?
Thanks and regards,

Hello Harald,
As per your definitions, speed limit of highway = 180 km/h, and vehicle's
speedFactor=0.9 which means that the vehicle can run upto 160km/h on the
highway (of course speedDev and sigma will affect it). Please clarify
and/or rectify my views.

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

[Tripplanner Mumbai]

The message "Makefile:140: recipe for target 'all' failed" is a summary
message.

> a) post the output of the make-run to the list

Ended in following error:
Makefile:140: recipe for target 'all' failed
make: *** [all] Error 2

Ended in Error:
Makefile:140: recipe for target 'all' failed
make: *** [all] Error 2

All the above errors are respect to August 15 version.

d) Someone else in this user group has an idea
