When facing a growth in demand, airlines tend to respond more by means of increasing frequencies than by increasing aircraft size. At many of the world's largest airports there are fewer than 100 passengers per air transport movement, although congestion and delays are growing. Furthermore,...

Purpose – This chapter provides a critical discussion of air to rail mode substitution. Environmental impacts, intermodal competition and integration are considered, examining advantages and disadvantages as well as opportunities and constraints.Originality – Both operation and life-cycle...

To date, relatively little is known about the nature of the demand for high-speed rail (HSR) soon after inauguration of the services, despite close to 50-year experience of HSR operation and 17 166 km of HSR network around the world. This is a real lacuna given the scale of HSR construction...

The article introduces a design process for policy packaging, combining a heuristic approach with a real world example of European policymaking. The policy packaging process is divided into six stages, starting with (1) the definition of goals and objectives, (2) the creation of an inventory of...

In addressing various policy problems, deciding ‘which policy measure to start with’ given the range of measures available is challenging and essentially involves a process of ranking the alternatives, commonly done using multi-criteria decision analysis (MCDA) techniques. In this paper, a...

The interdependence and complexity of socio-technical systems and availability of a wide variety of policy measures to address policy problems make the process of policy formulation difficult. In order to formulate sustainable and efficient transport policies, development of new tools and...

To keep load factors high while offering high frequency service, airlines tend to reduce the size of the aircraft they use. At many of the world’s largest airports there are fewer than 100 passengers per air transport movement, although congestion and delays are growing. Furthermore, demand...
