A CONTINUOUS TIME LINK MODEL FOR DYNAMIC NETWORK LOADING BASED ON TRAVEL TIME FUNCTION

Two requirements for a satisfactory dynamic network loading model are identified: a) an allowance for overtaking on a link and b) flow propagation through the network should be consistent with speed. The FIFO rule and its implications are discussed. The two requirements identified are investigated and a link model developed which is based on a travel time formulation rather than the commonly adopted exit function formulations. The model is then applied to small networks to show the ability of the model to explicitly deal with bottlenecks and to represent while-trip re-routing so that it can be used as a tool for the evaluation of control strategies. For the covering abstract see IRRD 886400.
