Abstract

When making decisions in infrastructure investments the Swedish National Railway Administration (Banverket = BV) perform socio-economic calculations. Input for the calculation consists of forecasts concerning future travel demand and traffic simulation for evaluating different alternative investments. Because of that BV in cooperation with AF-Industriteknik has developed a package of Simulation programs RTF (Running Time Program) and SIMON. RTF is used for train simulation (profits of reduced running time) and SIMON for traffic simulation (profits of extra capacity). The following briefly describes the simulation models and their use in Banverket's planning work. 1. Introduction BV has developed as well as initiated development of several simulation models. The models communicate with the Track
