Re: [sumo-user] Flow definition using Poisson
You can find a working example at https://sumo.dlr.de/extractTest.php?path=sumo/spec/flow/poisson_0.1
If it doesn't work for you, then the version of sumo you are calling is not 1.13.0
(a quick way to check is by calling 'sumo' on the command line without arguments)

Hello Jakob, 

Yes I am using the new version of sumo 1.13.0 on Ubuntu Linux. 

Regards
Radha

You need to upgrade to version 1.13.0 to use Poisson flows.

Sorry, but I have the same error with the period

Error: Attribute 'period' in definition of flow 'f1' is not a time value.
Error: flow cannot be created
Loading of additional-files failed.
Quitting (on error).

Many thanks Jakob,

Probably the SUMO website must be updated with the period instead of probability.

period="exp(0.01)" ....

(the period between vehicles comes from an exponential distribution)

Hello Again,

I tried to define the flow using Poisson distribution in the following way.

<flows>
            <interval begin="0" end="4000">
                <flow id="f1" probability="exp(0.01)" type="VehType" route="fromNorth"/>
            </interval>
    </flows>
<flows>
            <interval begin="0" end="4000">
                <flow id="f2" probability="exp(0.01)" type="typedist2" route="fromNorth1"/>
            </interval>
    </flows>

But I end up with an error

Error: Attribute 'probability' in definition of flow 'f1' is not of type float.
Error: flow cannot be created

Am I missing something? Where it went wrong please suggest to me.

Regards
Radha
