bouchonvm - mean speed computation ( circular road traffic )
Compute the mean speed of n cars confined to a circular road without input or output, where the cars cannot overtake each other.
The cars can take two speeds 0 and v with probabilities (1-l) and l.
In stationnary regime there are k clusters.
In this case it is possible to compute explicitely r :
r(n+1)=l(k+nr(n))/(n+k) with r(0)=1.
