Infrastructure encompasses existing transportation, communication and utility networks.
A good infrastructure is vital to economic vitality and often plays a key role in economic development. The need for fast, reliable and cost effective transportation and communications is driven by businesses operating in competitive global markets. Many manufacturers operate a 'just in time' supply and delivery process, which requires a highly efficient transportation infrastructure. Thus, community, regional and national infrastructures are under pressure to improve road, rail, air, and even waterway, transportation. Telecommunications companies and utilities, such as water and electricity, are also upgrading their services to cope with growth in demand.
