Abstract Transportation planning methods and practices have helped the automobile-dependent city to evolve. They have been based on what has been derogatorily termed a “predict and provide” computer-modeling approach, which treats traffic analogously to a liquid, something that retains its original volume regardless of the container into which it is placed—in this case, the capacity of the road infrastructure that accommodates it. This chapter will show how traffic is more like a gas that can be either compressed or allowed to expand, depending on the capacity provided for it. Historically, technical and computer-model-based approaches to transportation have fallen far short in providing the policy direction and vision required in developing well-functioning transportation systems in cities. As the age of the automobile diminishes, a more human-focused, holistic approach is needed. The global knowledge economy is focused in cities, and the jobs that now increasingly underpin urban economies are not dependent on the further extension of the automobile city fabric that traffic models are so adept at providing. These new jobs, as well as the many other benefits from reduced automobile dependence, will require the protection and extension of walking city and transit city fabric. This means an entirely new focus for the transportation planning profession and how computer models are used for future urban and transportation planning.
