 Dear Users,
 I used the tlsCycleAdaptation.py that based on Webster equation
 followed the command  " tlsCycleAdaptation.py -n net.net.xml -r

 But the result is " *There are no flows at the given intersections. No
 green time optimization is done*" as the picture named " i.png" that I
 attached with this email.
 Even though I created the traffic simulation model for this
 intersection that includes the given traffic light system.
 I will attach my simulation model to this email. Please double-check it
 and give me a suggestion to handle this problem.
 Thank you for your help.

[sumo-user] Car Following parameters - "Tau"

2019-07-24 Thread Soumya Sharma 
Hello,
I am working with the CACC model to determine how it impacts freeway
capacity. I studied in detail the algorithm for the CACC (
https://www.sciencedirect.com/science/article/pii/S0968090X14002447?via%3Dihub
 and
https://www.sciencedirect.com/science/article/pii/S0968090X1830528X?via%3Dihub).
In addition, I looked at the code at (
https://github.com/eclipse/sumo/blob/master/src/microsim/cfmodels/MSCFModel_CACC.cpp
).
However, I was not able to see how the time headway shown in two papers is
implemented in the code. I am particularly interested in decreasing this
parameter. I did try to work with "tau", however, it is still not clear how
"tau" is implemented in the CACC.

Interestingly, when I set "tau = 1" it gives me the maximum flow. Any value
greater (1.5, 2) or lower (0.1, 0.2, 0.3, 0.5) than 1 decreases the flow
rate per hour. Could you let me know how timeHeadway is implemented in the
CACC model and also what parameter should I change if I want lower time
headways (for example I want to have a time headway of 0.5 sec between
vehicles).
I have attached my files for reference.
Thank you in advance.

Re: [sumo-user] Issue trying to create route file using randomtrips and duarouter in Python (via Pycharm)

2019-07-24 Thread Harald Schaefer 
Hi

if I run randomTrips.py manually in a command window, i see

harald> randomTrips.py -v -n net.net.xml --route-file routes_123.xml
calling  /usr/local/share/sumo/bin/duarouter -n net.net.xml -r
trips.trips.xml --ignore-errors --begin 0 --end 3600 --no-step-log
--no-warnings -o routes_123.xml
Success.

This means inside randomTrips.py automatically duarouter is called. You
have nothing to do.
But duarouter is called with options to ignore-errors and not to issue
warnings.

Can you post the output of your randomTrips.py call?

Hi Harald, thanks a lot for the detailed response.

 Can you elaborate what do you mean by 'duarouter is called from
randomTrips with --ignore-errors'? What do I need to add to my code to call
duarouter within randomtrips loop?


Thanks again,

Hi,

your simulation starts at t ~ 28800
you should add the parameter - b28800 to the call of tlsCycleAdaption.py

for me it works in one of the latest development versions like this:

please select one or more lanes in netedit,
Go to additional mode, select „VariableSpeedSign“ and click use selected

Re: [sumo-user] Issue trying to create route file using randomtrips and duarouter in Python (via Pycharm)

2019-07-24 Thread Harald Schaefer 
Hi,

here are some ideas:
1) might be the routes_abc.xml file is locked by the sumo-gui and is not
overwritten (duarouter is called from randomTrips with --ignore-errors)
2) Have you tried your loop without the sumo_gui and checked that there
are new route_files?
3) you can use in each loop a new route file name.
4) does the sumo-gui processes terminate?
5) Have you tried absolute filenames?
6) Some parameter (period, seed) in your call to randomTrips are given
as int not strings

[sumo-user] Fwd: Regarding Variable Speed Signs

2019-07-24 Thread Radha Reddy 
Hello,

I have to place a variable speed sign on an edge.
But I do not understand how to place variable speed sign by using Netedit.
Can you please suggest me, how to place these kind of signs.

Regards
Radha
