ABSTRACT
We began this book by suggesting that urban areas were at a crossroads. Traffic congestion has existed for centuries and current observations suggest that it will not relent in the foreseeable future; this state of affairs suggests no visible crossroads. Notwithstanding relatively new urban developments (both greenfield and brownfield), cities’ core transportation networks (i.e., roads) and accompanying property lines and buildings have been established for many years. These facilities, legal constructs, and structures have long lives; this, too, suggests no imminent crossroads.
