This paper presents a multi-purpose tool to assess transport investments in congestible facilities. The model can handle any combination of passenger and freight transport modes in a simplified network. Within each mode, there can be competing operators. It is calibrated to a given traffic...

This paper studies maintenance and tolling decisions by two competing private operators of roads that experience depreciation and congestion. Duopoly generally results in higher social costs not only than in the first-best optimum but also the second-best optimum in which roads can be maintained...

This paper discusses the formulation of crowding in public transport and its implications for pricing, seating capacity and optimal scheduling. An analytical model is used to describe the user equilibrium and the optimal equilibrium for different stylized conditions. For the one OD pair case...

This paper examines the problems of peak period traffic congestion and the analysis of alternative congestion relief methods. It presents a dynamic model of the queues and delays at a single point of traffic congestion because there is ample evidence to suggest that the major delays to users...

Mode choice under stochastically varying demand is studied via a dynamic mathematical model which describes the behavioural interactions between population groups. The model is developed by assuming competing attractivity functions for automobile and public transit which motivate their use...
