While much of the transportation systems in Europe and the United States are mature (if not senescent), the rest of the world is still planning, developing, and deploying new systems. The accomplishments and mistakes of places like the United Kingdom and the United States, then, can teach uslessons that may be applied to places where transportation remains nascent or adolescent. The Transportation Experience seeks to understand the genesis of transportation policy in America and the UK, along with the roles that this policy plays as systems are innovated, deployed, and reach maturity,and how policies might be improved. The second edition updates all data that appeared in the first edition (published in 2005), and features significant revision of approximately half of the book. The book has been reorganized for improved presentation, and smoothly integrates all new material. This second edition also includes twonew chapters on safety and security in transportation systems and user interface.
