Re: [sumo-user] fundamental diagram

Hello,

for density, you need to use the total lane-length of the network rather than the edge length (edges with more lanes have more space).

Other than that, your formulas are okay.

Hello,

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.
