Zimmerman (planning and public administration, New York U.) investigates topical confluences between road and rail transport in the United States, environmental concerns, and security from terrorism and other extreme events, utilizing the concept of networks as a framework for integrating the three themes. Eight chapters are presented on the networked nature of transport and how it impacts environmental and security issues, the relationship between transport and climate change, more traditional environmental concerns that potentially influence transport, network-based solutions to environmental problems, natural hazards and accidents that disrupt transport, security threats to transport and federal government responses, and future directions of network thinking about these issues.
