INTEGRATING TSM INTO THE OVERALL TRANSPORTATION/PLANNING PROCESS

This paper will briefly sketch an approach that is strategic, tactical, and integrated within an overall process that unifies regional versus subregional demands, long-range versus short-range needs, and capital-intensive versus low-cost improvements, actions, policies, and combinations of such. Although this may seem overly ambitious, such an approach is overdue if we are to survive the babel of current requirements, funding conditions, and methodologies. Moreover, the North Central Texas Council of Governments (NCTCOG) in the Dallas-Ft Worth area is well on its way to implementing such an approach in a program that relates TSM actions to improvements in aeawide air quality. This approach has, basically, three stages: 1. Establishment of a regional context within which detailed subregional (corridor) plans can be developed, including assessment of growth in population and employment and identification of regional TSM actions that could be implemented and of committed transportation facilities that will be in place. 2. Development of Subarea (Corridor) transportation policies and plans within the constraints of regional growth and transportation actions. 3. Synthesis of an overall regional transportation plan from the policies and plans developed for each of the subareas of the region. This approach could represent a major breakthrough in the planning process. It has been made possible by the development of simulation software that permits focusing on an area of interest while simultaneously dealing with the remainder of the region and of sketch-planning software that permits estimation of regionwide effets. The simulation software has the additional advantage of being able to handle finely detailed networks and very small zones at a subarea level so that impacts that might be lost in the regional approach may be simulated and evaluated. By applying this approach to all of the subareas of an entire region, a set of subarea plans can be developed. (Author)
