Hi, hope all of you are having a good time. 

I'm new in Arena (extremely new), and 'cause I'm planning to simulate a roundabout, I have no idea how to start. 

For example, I don't know if use a kind of "pair" for each route like, Create and Dispose and put a Process Module in the center, then connect the Create modules and Dispose ones. 

UPDATE #1: Well, the roundabout problem is quite simple.

I have 4 intersections with thier own flow properties, like time arrival, time in the queue, types of vehicules. and we have off course the Server wich is the roundabout trying to attend the four ways (paths or intersections).

My doubt is, how can I model it in rockwell?.  For example I was thinking about to represent each way as a pair of Create and Dispose.

My doubts are:

• What kind of elements appart of Create and Dispose elements, can I use to represent the flow showed in the pic?
• How can I verify if a vehicle can get inside into the roundabout or have to wait?
• How can I show a report of the results and get the Poisson distribution?
• How can I animate it?

I already have the queue parameters for each ways, as I mentioned.  Sorry for have too many doubts, I just found this site a good way to learn and improve my knowledge between other teachers and students.

PS. Sorry for my english.

Thanks for reply
