Source: some data from Living Planet Report, 2006 and Summary result of second Eurostat questionnaire on CFC on public infrastructure, DOC.CFC 15, Eurostat, 2003. The lifespan of a transport asset is the approximate number of years over which it is expected to perform under normal operating conditions while receiving regular

(eds) Inserting Port-Cities in Global Supply Chains, London: Ashgate. Transport service operations and the associated traffic flows do not take place in a vacuum. Transport markets

A common fallacy in understanding and assessing the economic impacts of transport investments is the lack of consideration of the diminishing returns these investments can face. Three main geographical contexts in which similar transport investments can have different multiplying effects are identified: The impacts of transport investments are thus highly influenced

Technological innovation and economic growth are closely related and can be articulated within the concept of cycles or waves. Each wave represents a diffusion phase of

Authors: Dr. Jean-Paul Rodrigue and Dr. Theo Notteboom Transport supply is the capacity of specific transportation infrastructures and modes over a time period. Transport demand is mobility needs for the same time period, even if they are only partially satisfied. 1. The Supply and Demand for Transportation Each transport mode shares

Authors: Dr. Jean-Paul Rodrigue and Dr. Theo Notteboom Transport costs are a monetary measure of what the transport provider must pay to produce transportation services. 1. Transport Costs and Rates Transport systems face requirements to increase their capacity and reduce mobility costs, an objective that has seen continuous improvements in

Author: Dr. Jean-Paul Rodrigue Transport systems support complex economic and social interactions and are thus a component of society. Transportation reflects the aspirations of a society such as accessibility and mobility, which expands its horizon. 1. Mobility and Society Mobility is one of the most fundamental characteristics of human activities.

Authors: Dr. Jean-Paul Rodrigue and Dr. Theo Notteboom The development of transportation systems is embedded within the scale and context in which they take place, from the local to the global and from environmental, historical, technological, and economic perspectives. 1. The Economic Importance of Transportation Development can be defined as

Source: Adapted from Wikipedia. Very few public transit systems worldwide generate enough revenue from fares to cover operating expenses. This is even more challenging if capital costs, such as infrastructure investments, are considered. The profitability of a transit system is usually measured using the farebox recovery ratio, which is the

Issue Challenge Freight volumes Capacity of urban freight transport systems (congestion). Lower driving speeds and frequent disruptions (reliability). Distribution sprawl (space consumption). Nature of freight distribution Smaller volumes and time-sensitive freight (frequency and repetitiveness). Cold chain (shipment integrity). E-commerce (home deliveries). Environmental issues Mitigate environmental externalities (emissions, noise). Growing demand
