The emphasis on low-cost, short-range transportation system management actions implies the need for more detailed data to support decision making at a smaller scale. Ideally, such data would be developed efficiently and in a manner conducive to identification of problems and opportunities and, ultimately, formulation and programming of improvements. At the same time, such data must permit planners to perform the necessary trade-offs of traditional mobility objectives against the increasingly important objectives of improved air quality, reduced energy consumption, and responsible fiscal management. This paper describes the development and case-study application of a diagnostic framework for subarea-level identification of problems and delineation of improvements. The necessary level of detail is provided by use of the thoroughfare planning system, a subarea focusing methodology. A framework is set forth for using such a tool to develop diagnostic measures pertaining to environmental as well as mobility objectives. The diagnostic measures obtained in a case-study application are described. Further, the use of these measures to formulate an improvements program within the case-study setting is reviewed, with particular attention to the packaging of individual candidate projects into distinct alternatives for evaluation and selection. /Author/
