Network Transmission Model: a Dynamic Traffic Model at Network Level
The Macroscopic or Network Fundamental Diagram (NFD) describes the traffic flow in an area as function of the number of vehicles in that area. In recent years, the NFD has been experimentally validated. Gating has been mentioned as most promising as the main application of the NFD. However, a state description in only a few parameters also gives advantages for setting up a dynamic traffic simulation program.This paper uses this advantage and proposes the Network Transmission Model, a dynamic simulation program based on the NFD. The network is split up into subnetworks (cells), for all of which an NFD is defined. Based on the accumulation, the flows between the cells are determined. Contrary to earlier approaches, the method is applicable to a many-subnetwork system and accounts for the limited capacity from one subnetwork to the next. The model is applied to a network showing the calculations of various control schemes, including routing and gating.
