Better integrating environmental considerations into system design represents perhaps the greatest opportunity for transportation which, after all, is really a system of systems. Developing efficient transportation systems that provide effective modal interchange points enables all the modes to operate together as one system enhancing social, environmental, and cost benefits significantly. These transportation systems must take into account the needs of the region and use a lifecycle approach. For example, limiting material use during manufacturing may reduce environmental impacts slightly, but result in heavier aircraft with more significant impacts during the life of their operation.
