Re: [sumo-user] Problem about the DUE in simulation

[Jane Cheung]

Yun-Pang,

Thanks for your reply!
In my case, I also want to do other optimization at 3600 s which will also
change the route. In other words, there' are two steps I want  to
1) First, do my specific optimization algorithm that will influence the
traffic flow from 3601s-7200s,
2) then, use duaIterate.py  to get the equilibrium traffic flow based on
the optimized traffic time in step 1).

The problem that confused me is how could I use *duaIterate.py* to generate
the optimized routes in step 2) during the simulation?
What I can do is to use * duaIterate.py* *before* simulation and use the
last step iterated  ROUTE file as the ROUTE file in sumo.cfg (as you reply
in email )and run sumo.exe at my defined simulation start time, like 0s. I
wonder is there some methods I could do * duaIterate.py(* iterations = 50)
at 3600s and then reload  *duaIterate.py(* iterations = 50) generated route
file and let the simulation continue with that route?

Appreciated!

Best regard,

Jane Cheung

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

[Jakob Erdmann]

When I run your simulation (run.sumocfg), I get 2341 loaded/unloaded
persons in stop-output.
I used attributeStats.py -e stopinfo -a loadedPersons stops-out.xml -p 5
and this gives 622 stops with an average of  3.76367 loaded/unloaded

At the end time of 36000 there are still 28 persons in the simulation
according to the log.
You can also check this by comparing the input count (9000 persons) to the
tripinfo output count (8972 persons).

Looking at the simulation reveals that these persons are waiting at a
busStop after all buses have already left. Some of them such as person 6064
have already used a bus by that time which creates a discrepancy between
loadedPersons and ride count in tripinfo-output.

The pedestrian collisions are (among other things) caused by vehicles that
drive on the sidewalks due to being configured with vClass="ignoring".
The pedestrian jamming (which could be caused by mis-dimensioned
sidewalks/crossings) could be responsible for persons missing their buses.

regards,
Jakob

 Hello,
 Recently, I implemented public transit lines in SUMO. I encountered
 that the number of passengers boarded at a stop according to stop output,
 does not  match with the number of passengers making successful trips
 according to trip output. I was assuming that every passenger who boards
 into some bus at any stop has an entry in trip output as well. I tried with
 TraCI as well as a simple command line, but in either case, I found that
 the passenger count varies. Typically, the total number passengers boarded
 (as per stop output) is greater than the total number of passengers in the
 trip output. However, when I extracted additional data through TraCI, then
 I found that the number of passengers at various stops as per stop output
 is the same as the extracted information about each passenger through 
 TraCI.

 I am attaching my network along with TraCI code (demo-i.py) to be
 tested by others. Also, I am attaching a few csv files which I have
 extracted from the xml output files for easier reference.

 Please clarify if the stop output count of passengers has to be the
 same as the number of trips as per trip output or not.

Re: [sumo-user] Problem about the DUE in simulation

[yun-pang.floetteroed]

Dear Jane,

To get an assignment result, which is reached or closed to a DUE state, you can 
use duaIterate.py under the Directory “tool\assign” of your SUMO Directory.  
The duaIterate.py will do the traffic assignment with the DUE-objective 
iteratively until the defined number of iterations is reached. At each 
iteration, the traffic state in the previous iteration will be used for traffic 
assignment.

To facilitate the whole assignment process you can also use SUMO’s rerouting 
options at the same time so that simulation objects can consider the latest 
traffic information for mode/route choice during simulation. In order to do 
that you need to give the following commands in addition to the required inputs 
(as indicated “…” below) when running duaIterate.py, where 1.0 means all 
vehicles have the rerouting devices, and 300 means the traffic information is 
updated every 5 mins for vehicles with rerouting device. Of course, you can 
adjust these values according to your need.

duaIterate.py  sumo--device.rerouting.probability 1.0 
sumo--device.rerouting.period 300

After running the duaIterate.py you can check the route travel times of the 
simulation objects in the last file ‘*.alt.xml’ , which is an alternative route 
file generated by the duarouter at each iteration. If the time difference is 
larger than your threshold, you can increase the number of iterations in the 
duaIterate.py and re-run the script.


I hope, this helps.

Best regards,
Yun-Pang

Betreff: [sumo-user] Problem about the DUE in simulation

Dear all,
Could anyone give me some suggestions on how to reroute routes for vehicles 
that have not finished their journeys with DUE algorithm during simulation?
For example,
After the simulation running 5min( the duration for the simulation is 20min ), 
I would like to refresh the routes for all vehicles moving or going to insert 
in my network. After refresh routes, the traffic flow state is in DUE.
How could I realize it?

Any kind of help would be appreciated!

Re: [sumo-user] Generate the renew route in cousmerized intervals

[Jane Cheung]

Jakob,
Thanks for your reply!

There is one more question.  I will use a more specific way to describe my
problem.

I build the *sumo.cfg, *which contains specific route.xml and other
essential files. The simulation period is 0-7200s.

Then, I start my simulation at 0s. When the simulation time reaches 3600 s,
I would like to let all vehicles moving in the DUE (
https://sumo.dlr.de/docs/Demand/Dynamic_User_Assignment.html#iterative_assignment_dynamic_user_equilibrium
)state(not private optimization state) in the last simulation time (3600 s
- 7200 s).
As described in the document, the command to do that is :
python duaIterate.py -n  -t  -l 
Where the route.xml or trips.xml needs to be the renewed route.xmL instead
of the original route.xml at the 0s.


To use the command above to get the equilibrium traffic flow at the time
point 3600s, how could I get the renewed* route.xml *file when my*
simulation* running at 3600s? After that, the simulation still can run
continuously to reach the predefined end time point in my simulation？

Best regards!

Jane Cheung

Re: [sumo-user] mean speed - traffic measures output

[Jakob Erdmann]

Speed is just the average of all speeds on the edge over the given time.
Each time step the speeds on the edge are sampled and the average of all
samples (over the specified time interval) is used. Slower vehicles spend
more time on an edge and thus contribute more samples and this explains the
difference to a point-average of speeds.

Re: [sumo-user] reading laneData using socket connection and xml2csv.py

Hi Sasan,
those buffers are usually not time triggered but are flushed to the

You may try to add some calls to flush() in the xml2csv script and also

[sumo-user] mean speed - traffic measures output

[Natalia Liora]

Hi,

In the generated output file for the traffic measures for each edge/lane 
(https://sumo.dlr.de/docs/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures.html)
 
the definition of estimated mean speed is given as "This is an average over 
time and space (space-mean-speed), rather than a local average over the 
vehicles (time-mean-speed). Since slow vehicles spend more time on the edge 
they will have a proportionally bigger influence on average speed. “

How the term “space” is defined ? Could you please specify how exactly the mean 
speed has been estimated?

I understand that the generated speed does not take into account the mean speed 
value over all the vehicles per second counted on the edge  and finally 
averaged over the whole simulation period, right ? 

Thank you.

Natalia

Re: [sumo-user] SUMO: Queries

[Jakob Erdmann]

Hello,

1) Yes. You can use fromXY and fromLonLat to define vehicle trips: see
https://sumo.dlr.de/docs/Demand/Shortest_or_Optimal_Path_Routing.html
2) Yes. You can define a route that consists of only two non-consecutive
edges. A new vehicle with such a route will infer that it must find a route
between both edges (i.e. it will be treated like a trip definition).
3) traci._vehicle is the internal module that holds the code (you cannot
use this directly). traci.vehicle is an object constructed at runtime based
on _vehicle which you need to use in order to make traci calls

regards,
Jakob

Re: [sumo-user] Generate the renew route in cousmerized intervals

[Jakob Erdmann]

Duarouter and Sumo use the same code for routing. You can therefore use
TraCI routing commands to accomplish this:
https://sumo.dlr.de/docs/Simulation/Routing.html#traci
Alternatively, you could store the state of the network (in regard to
averaged travel times) using either
-
https://sumo.dlr.de/docs/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures.html
-
https://sumo.dlr.de/docs/Demand/Automatic_Routing.html#investigating_edge_weights
And then load the generated file along with the custom route input file
into duarouter.

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

[Jakob Erdmann]

tripinfo-output only contains persons that have completed their whole
itinerary (all walks and rides). Since your configuration ends the
simulation at step 3600 it will prevent output of all persons still
travelling at that time even though they already rode a bus and thus show
up in the stop-output.

Re: [sumo-user] DFROUTER Detector type is discarded for most of detectors

[Jakob Erdmann]

Hello,
using  only edgeData will work just fine. To make use of the edgeData that
you generated (counts are stored in 'qPKW`), you need to set routeSampler
option
--edgedata-attribute qPKW
If your flowfile contains temporal changes in flow, you need to update
edgeDtataFromFlow.py to the latest development version because the version
released with 1.6.0 does not handle the time-information correctly.
https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version

Jakob

Re: [sumo-user] routeSampler: no routes pass edge error

[Jakob Erdmann]

The error refers to the routes from your input sample. They do not contain
a single route that passes these edges. If your routes come from
randomTrips you could simply increase the sample size by changing the value
of -e from it's default of 3600 to a higher number. Of course, you could
load routes from another hand-crafted file if you have ideas about where
vehicles passing A and B should come from / go to.
