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

Three land use dimensions are impacted by public transit, namely transit access points. These are influenced by the level of transit use: Accessibility. The sole purpose of a transit stop is to provide accessibility to the transit system, such as stops along a bus route or subway station. Land use

Urban areas, as economic units, are influenced by globalization in the scale and scope of their development. Since globalization was relying on different technological and economic drivers through time, this temporal

Rigamonti (2002) “Urban Mobility and Urban Form: the Social and Environmental Costs of Different Patterns of Urban Expansion”, Ecological Economics, Vol. 40, pp. 199–216. The urban expansion of land uses can take place in five general forms: Infilling. New developments are

Urban activities such as retail or manufacturing have spatial locations from which a land use pattern is derived and influenced by the existing urban form and spatial structure. This form is strongly related to the types of activities that can roughly be divided into three major classes: Routine activities occur

Author: Dr. Jean-Paul Rodrigue The most important transport challenges occur when urban transport systems cannot adequately satisfy the requirements of urban mobility. 1. Urban Transportation at the Crossroads Cities are locations having a high level of accumulation and concentration of economic activities. They are complex spatial structures supported by infrastructures,

Author: Dr. Jean-Paul Rodrigue Urban mobility involves three broad categories of collective, individual, and freight transportation. While the mobility of passengers is the outcome of individual decisions based on different rationales, freight mobility is decided in tandem between the cargo owners and transportation service providers. 1. Urban Mobility and its
