The planning of underground transit systems (subways, metros) has to account for construction, operating and fleet cost as well as the level of service provided to passengers. Subway routes can be planned with few restrictions taking advantage of advanced tunnelling technologies. Consequently, planning of subway networks for a given distribution of station locations can take into account the sum of passenger travel time, transfer costs and subway fleet, operating and construction costs. Two network theory methods are shown to be particularly useful in the subway network planning process. Research is still in progress to address network reliability and subway operational aspects. Modelling frameworks available to analyse merits of incident management methods are being explored with the view of identifying effective traffic management responses to prevent cascading schedule failure.
