1. Introduction
The importance of effective infrastructure management is becoming a focus worldwide as resources and budgets are being impacted by the global financial crises. One important aspect of infrastructure management lies in governance and coordination of stakeholders and investors. Governance within this context provides the strategic direction for the development and maintenance of complex infrastructure between sectors, industries, public utilities and government ([20] Keast et al. , 2010). This challenge is highlighted in the nexus of infrastructure connections between the urban core and the airport. The modern airport is a global connection for the social and economic interaction of cities, which requires well-connected infrastructure links to the urban and regional centres to service this international interface. Thus, the airport has evolved as a critical element in the infrastructure network - connecting local, regional and global markets. The sustainable development and management of infrastructure that connects airports to markets is increasingly becoming an issue around the world as cities and countries compete at a global scale.
The role, scale and meaning of major urban airports worldwide have changed over the past decade as a result of corporate and economic transformation. Modern airports are very different from the traditional view of airports, and our current knowledge is insufficient for understanding the complex roles and relationships now associated with airports ([14] Freestone et al. , 2006; [29] Stevens et al. , 2010). The airport can no longer be considered in isolation from the metropolis that it serves. Large international airports in Europe, North America and Asia have varied functions beyond airport traffic and operate as metropolitan hubs with a diverse range of land uses. Most large international airports have developed land on the airport for commercial and light industrial purposes that are often not associated with aviation-related uses.
The change in land use around the airport, coupled with the increasing use of the airport for international travel, has often placed demands on the transportation infrastructure that services the airport area. Included in this demand is a wide range of stakeholders, users and infrastructure providers that have differing goals, objectives, models and interests. The "simple road" to the airport is now a very complex infrastructure linkage that services a multi-nodal transportation hub surrounded by diverse land uses....
