A Simple and Pragmatic Representation of Traffic Flow

This paper concentrates on a particular approach to understanding the mechanics of traffic flow that grew out of the development of a model to simulate travel times on long routes. This model, which has both deterministic and stochastic components, is used by the National Roads Authority to simulate the mean and variance of journey times on Ireland's primary road network, and in particular to assess the impact of road improvements. Obviously, this model is on a completely different scale, and can have a cruder representation of road infrastructure characteristics than is envisaged here. Nonetheless, it is thought that the basic approach, and especially the macroscopic and deterministic component of the model, has interesting features that would appear to be applicable outside its immediate practical use in simulating travel times for long routes.
