Re: [sumo-user] Randomness at vehicle departure
Hello,
the only built-in distribution you can get with <flow probability="..." .../> is the Bernoulli Distribution with can be used to approximate the Poisson distribution (https://en.wikipedia.org/wiki/Binomial_distribution#Poisson_approximation). For everything else you have to generated your own xml input of individual vehicles or trips with pre-computed departure times that follow the desired distribution.

regards,
Jakob

Hi,


I am new to SUMO and notice from the user document that SUMO can insert vehicles in a equally-spaced or randomized manner. I wonder if it is possible to have user-defined randomness at vehicle insertion? For example, can I by some means regulate that the departure time between consecutive vehicles follows a certain distribution (e.g., Poisson)?


Thank you!

Jie
