Just a quick follow up: The issue is actually more complicated than it seems and there are different methods to compute the network-wide FD._______________________________________________Am Mo., 15.

In the fundamental diagram calculating process, for a specific interval (for example [0-t] and n edge) are below relationships correct?
Mean density = total number of vehicles/total length of the network
Mean speed= sum (3.6*speed of every edge*number of vehicle of every edge) / total number of vehicles
Flow = sum (3.6*speed*density) for 0 to n.
And then repeat this process for every interval and then draw a plot based on these points and these plot gives me a flow density diagram for the whole network.
Is this process correct?
Thank you.
