Thank you for your kind response. I had one more doubt. Can we have different values of the user-defined car following model parameters "I", "d" for different edges of a road network?
eg. We have a road network of edges (e1---e2---e3) and say edge 1 has value i = 2, d = 10, and edge 2 has value i = 5, d = 40 in the same road network.
