A few years ago the Northern Virginia Transportation Authority approved the so-called Trans-Action 2030, a transportation plan that included the Washington, DC metropolitan area. This plan is worth being analyzed because it reflects the contemporary state of the art, the current beliefs, and unfortunately, also the desperate invincible conservatism. The plan is clearly the output of the most advanced approach to transportation by civil engineering. Social scientists were employed only in marginalized roles and social research was almost completely neglected. As long as the planners have acted in the civil engineering discipline, they have been consistent with their methods and have proven high-level professional skills, no matter how we may have argued their opportunity. When the planners tried to apply social research and to face environmental concerns, they demonstrated a humiliating incompetence and the plan lost credit. The analytic description of the plan and the detailed criticism from social science and environmentalist approach points of view, is carried on in order to introduce the following chapters in which I propose how professionals other than civil engineers can deal with traffic problems and how different solutions can be employed to mobility problems in the future.
