The Brooklyn Bridge An Example of a Pioneering and Sustained Urban Infrastructure

Enable current and future generations to be resilient to anticipated and unanticipated changes in economic, environmental, political and social systems. This means that infrastructure systems should be adaptable to unforeseen demands and technical capabilities. 

Sustainability is achieved in communities and supported by numerous infrastructure systems, rather than in individual infrastructure systems in isolation. Building sustainable communities requires involvement of stakeholders, users, and producers of the various systems, with new paradigms of collaboration, bold approaches to innovative solutions, and integration of infrastructure systems. 

The technologies and engineering approaches that were reviewed in the workshop exist—at least as prototypes or demonstrations— but can be enhanced substantially for greater sustainability. Discussions focused on  

These topics can be elaborated for any infrastructure system, with substantial commonality among systems. As an illustration, the following case study is presented. 

Advanced, fuel-efficient, and sustainable products will incorporate the following characteristics real-time fuel economy information for drivers sensor fusion and lower cost sensors materials, such as shape memory alloys, with a greater range of activation temperatures engineered nanomaterials and composites advanced batteries and infrastructure for refueling/recharging electric and hydrogen vehicles.
