In this paper an advanced macroscopic traffic model is presented that is capable of a seamless simulation of individual traffic streams. The approach is based on the knowledge about the distribution of flows on paths through the network. With these flows, all key and computation intensive calculations can still be performed only in one layer. The other path-layers are only used for storing the detailed data per path. This helps to keep the additional computation and organizational overhead at a minimum. Important fields of application of a path based simulation model are traffic control systems, rerouting and traffic assigment algorithms. The following presentation is for simplification reasons based on the equations for freeway street sections, nevertheless it can be applied to complex road networks in urban or interurban scenarios.
