Quick scan methods aim at a fast and transparent analysis of alternative solutions to planning problems in a situation of shortage of information. They generate new knowledge about solutions in early stages of decision making and in 'creative experiments' in scenario analysis. The importance of...

A rail journey is rarely an end in itself but almost always part of a journey 'chain' which include access to and egress from the railway station. The integration of the rail-journey components is essential to achieving a continuous travel, door-to-door, when using the rail and to make the rail...

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...

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...

Freight transportation system is critical to economic activity but it carries significant environmental costs, notably GHG emissions and climate change : energy use and corresponding CO2 emissions is increasing faster in freight transport than in other sectors and this increase is primarily the...
