SATURN: A MODEL FOR THE EVALUATION OF TRAFFIC MANAGEMENT SCHEMES

The model Saturn (Simulation and Assignment of Traffic in Urban Road Networks) may be considered as a highly enhanced assignment model, investigating as it does the effects of traffic management on flows in the network. The enhancement arises from the use of a simulation model which, as well as providing information for the assignment on the variation of delay with flow for each turn, can be used to assess the more general impacts of traffic such as noise. Because of the critical nature of the delays at intersections, these are modelled in considerable detail. The purpose of this paper is to describe in detail the structure, the assumptions made, the data requirements and the possible output from the model. After describing the assignment-simulation loop which is the basis of Saturn, it then describes the two stages in detail. The running of the complete model is summarised and details given of the practical experience of its use to date. Finally, some possible future developments are mentioned.(a) (TRRL)
