Investing in transport infrastructure

Investment in infrastructure can be divided into two major categories, namely investing in &s;infrastructure as a business&s; and investing in &s;infrastructure as an asset class&s;. This chapter considers the use of the transport infrastructure resilience indicator (TIRESI) and its rating system from the point of view of different stakeholders involved in transport infrastructure projects. It provides a more in-depth discussion on the overall-TIRESI (O-TIRESI). This version of the TIRESI may be useful to less knowledgeable stakeholders as it aims to summarise information coming from the static-TIRESI (S-TIRESI) and/or the dynamic-TIRESI (D-TIRESI). The O-TIRESI may guide project-related decisions and its computation methodology is sufficiently flexible to accommodate different stakeholder value systems. The concept of sustainable development is usually taken to encompass the need for finding an acceptable balance between the priorities of economic development, social progress and environmental protection.
