Chapter 30: Frequency-Based Transit-Assignment Models

This chapter focuses on the problem of predicting passenger flows and levels of service on a given transit network that consists of a set of fixed lines, normally known as the transit assignment problem (TAP). This is an important topic of public-transport system analysis. Transit assignment models are widely used as planning tools at strategic and operational levels, both in developed and developing countries. As such they are a critical block of multimodal network models of urban transportation systems. Important decisions concerning investments in public-transport infrastructure or services are normally supported by evaluation methodologies based on this sort of model.
