Re: [sumo-user] Traffic generation by using Poisson distribution

[Jakob Erdmann]

This runner file generates Vehicles with a Bernoulli process and thereby
achieves a binomial distribution as already recommended. The Poisson
distribution is the asymptotic limit of increasing the number of insertion
attempts (with proportionally reduced probability) which, as already noted
is not achievable due to time discretization.

Dear Jakob,

Many thanks for your kind response, the runner.py file associated with the
TraCI_TLS example.

- SUMO provides multiple runner.py files. Which one exactly do you mean?
- Since SUMO is a time-discrete simulation anyway (In every simulation step
you have to decide whether to insert a vehicle or not), I recommend that
you use the Binomial Distribution which is quite similar to the Poisson
distribution. Traffic flow with Binomial distribution is supported by
defining a  with attribute probability. See
https://sumo.dlr.de/docs/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#repeated_vehicles_flows

Re: [sumo-user] NETEDIT: custom connection shape - confirm/end editing?

[Albert Jeans]

I ran across this problem too recently. The Enter key had no effect. I
think I ended up restarting NetEdit to work around it.

Re: [sumo-user] NETEDIT: custom connection shape - confirm/end editing?

[Jakob Erdmann]

Saving the shape should happen when you hit the 'Enter' key. Also, hitting
Enter should end the shape-editing mode (indicated by the fat green
poly-line).
I am unable to reproduce the problem you describe.
What does happen when you press enter? Is there some output? Can you
confirm connection-editing with the enter-key?

[sumo-user] Traffic generation by using Poisson distribution

[Radha Reddy]

Dear Jakob,

I really appreciate your time for answering a lot of questions.

In the SUMO provided runner.py file, the traffic flow is generated by using
Random and Uniform distribution.

Can we use Poisson distribution instead of Random (may be yes). Can you
please share any example in which Poisson distribution is employed for
routefile generation?

Regards
Radha

[sumo-user] NETEDIT: custom connection shape - confirm/end editing?

[GregorJo]

Hi, i am trying to set a specific connection shape for an internal junction
edge with NETEDIT.
How do I confirm/save the modifications to the green "edit shape" when I am
satisfied with the new trajectory?
As soon as I leave the "move node" mode, the connection reverts to the
default shape.

I have tried both "enter" keys on my keyboard. Also, "Escape" does not seem
to leave this mode.
I am using NETEDIT 1.3.1

Reproduction: Open a network, enter inspection mode, check "show
connections", rightclick internal edge, click "set custom connection shape",
modify the green polyline.

What am I missing? The documentation says "confirm with enter or abort with
escape", but neither key seems to do anything

Regards, Gregor

you need load the type file using option --type-files or -t

Hi,

I’m not sure whether I’m doing something wrong or the feature is broken, but 
I’m trying to convert an OpenDRIVE file to SUMO network file using an edge-type 
file to also convert sidewalks etc. I tried a few different OpenDRIVE files, 
but all with the same result that the edge-type file has no influence. E.g. I 
call “netconvert --opendrive myOpenDRIVE.xodr -e conversion_edge_types.xml 
--output.original-names -o mySUMOnetwork.net.xml

And I use an edge type file like this:







Neither are sidewalks imported nor is the non-standard speed or allowance of 
type driving recognized. In fact it seems as if the file isn’t used at all. 
However, if I corrupt the edge-type file on purpose, errors are thrown as 
expected.
