I'm in the process of developing a traffic simulation using Discrete Event Simulation approach.
So I have the core stuff working but I need to have some sort of distribution to tell the simulation how many vehicles to be generated for instance per minute. Mathematics isn't exactly my strong side but so far I've figured that I need to implement a negative exponential distribution.
What I want is to have vehicles or let's simply call them events in this case, to be generated with some distribution which I think (correct me if I'm wrong please) I can use the exponential distribution for my needs here.
The problem I'm having (a quite big problem) is that I don't understand how it works. Researching about it seems extremely overwhelming and I end up getting confused. So I obviously need to understand it before I can implement it.
Could someone be so kind and try and explain to me how it works. I understand so far that it tells us for example if we know that there are two cars passing a certain point on a road every minute then we can calculate the probability for how long we have to wait until the next car arrives?
Also any material that you think I should read and lastly whether using the exponential distribution is suitable in this case.
