This makes me think again for my own problem .amazing. as I said explicitly in above post#3 with an example that assuming 4 pedestrian arrive within the time window ##T## which is started by the first one. So, I am looking to find the waiting time distributions of pedestrians who are now going...
Homework Statement
Pedestrians approach to a signal for road crossing in a Poisson manner with arrival rate ##\lambda## per sec. The first pedestrian arriving the signal pushes the button to start time ##T##, and thus we assume his arrival time is ##t=0##, and he always see ##T## wait time. A...
Actually I have not that much idea how to assess the accuracy of approximation, need to explore further, but I just developed a program that runs this process for 1 million time, interesting the empirical cdf of ##W_k## matches cdf of my approximation. would it be enough to verify the...
Hmm, I have been thinking over the night about it, what is your opinion if I say that, consider only a time interval ##0## to ##T##, first pedestrian pushes button to start the process, now forget about this pedestrian. The remaining pedestrians arrive following poisson process with rate...
It is ##C## and since it is not 1. Do I need to multiply ##\frac{1}{C}## with ##\frac d {dw} P(W_k \leq w | W_k \leq T)= \frac{ \frac{ \lambda^k {(T-w)}^{k-1} e^{-\lambda (T-w)} }{(k-1)!} }{(1-e^{-\lambda T)}} ##
Limits should be from ##0## to ##T## for integr.
(What limits do you have to evaluate ##\sum_{m=0}^{k-1} \frac{{(\lambda (T-w))}^m e^{-\lambda (T-w)}}{m!}## at?)
I am a bit confused as I am plotting the pdf of ##W_k## and ##t_k## in MATLAB for the above process. For the time vector ##t## on X-axis, I plot the pdf of ##t_k## using its density function ##f_{t_k} (t)= \frac{ {(\lambda t)}^k e^{-\lambda t}} {k!}## for time vector ##0\leq t \leq T##. Thats...
for plotting pdf of ##t_k## and pdf of ##W_k## against a time vector e.g., ##t=0:0.01:T##(minutes) on x axis, I need to replace ##w## in pdf of ##W_k## with ##t## such that
##f_{W_k} (t)= \frac{ \frac{ \lambda^k {(T-t)}^{k-1} e^{-\lambda (T-t)} }{(k-1)!} }{(1-e^{-\lambda T)}} ##...
