GB NATIONAL TRANSPORTATION MODE - DEVELOPING A DETAILED RAIL DEMAND MODELING FRAMEWORK

This paper describes how the National Transport Model (NTM) has played a key role in the formulation of the Government's Ten Year Plan for transport. Since its beginning, it has been undergoing a wide range program of development in order to make it more nitrated and spatially oriented. One important element in this development has been the creation and inclusion within the NTM framework of the National Rail Model (NRM), to enable the impact of various transport policies to be assessed in a truly multi-modal fashion. As such, the emphasis has been on developing a model capable of capturing the strategic interactions between rail and other modes, rather then aiming to model in detail demand on particular rail routes. Nonetheless, the NRM comprises a geographical representation of the entire rail network, covering all station on the rail system and London Underground. This integrates with the core mode-choice model of the NTM known as "Pass 1." This paper has developed a rail modeling framework that integrates with the Pass 1 model is consistent with the Strategic Rail Authority's (SRA) PLANET model. The Pass 1 model generates a multi-modal trip matrix based on model costs and fixed trip generations/attractions. It has been linked to the uni-modal FORGE model of responses to highway congestion, via a highway assignment of disaggregated Pass 1 car driver trips to 10,000 zone network. The FORGE model outputs road generalized costs for input to the Pass 1 process and the whole system operates in an iterative manner until basic convergence is achieved after a small number of iterations. The main deficiency in the system was the omission of a detailed rail model, parallel to the FORGE model, so that the true interaction between public and private transport can be modeled at the required spatial detail within the model structure. The objective of this paper was to develop the rail modeling framework and the necessary interfaces to the Pass 1 model.
