London Underground has experienced major growth in passenger demand since 1981 which has been accompanied by changes in the pattern of demand at some stations. Current congestion requires careful analysis before further construction takes place and demands an improvement in methodology. The paper reviews the modelling procedure which combines the simulation approach of the London Underground SCM (Station Congestion Model) with an adapted SATURN congested assignment model. It describes the development of the programs called the PEDROUTE package to create the network and travel demand files and to control their interaction. The data requirements are discussed both for developing a PEDROUTE model and validating its output. London Underground Limited has appointed Halcrow Fox and Associates to study current pedestrian flows using the PEDROUTE package and assess the effects of planned developments at Waterloo station. Waterloo is a large passenger interchange served by three British Rail routes and two Underground lines. There is also provision for an International Terminal for Channel Tunnel services and the extension of the Jubilee line as a third Underground service. The paper describes the application of the PEDROUTE package at Waterloo and will assess the results and performance of the model.
