TIME-AREA CONCEPT: DEVELOPMENT, MEANING, AND APPLICATIONS

The concept of time-area occupancy by vehicles captures in the same unit not only the quantity of ground area (or space) that is required for safe vehicle movement or for storage but the period of time for which the area is occupied as well. Another advantage of time-area measure is that it links the two usually different concepts of static and dynamic transport units (either vehicles or persons) under a common variable, the time-area that they consume. Moreover, it allows efficiency to be evaluated in terms of consumed versus available time-area. This is particularly useful in comparing different transportation modes. The history of development of this concept is reviewed; previous use had been confined to cursory analyses of modes, except for pedestrian facility operational analysis and design. Further research of this concept and its applications is presented. Some basic concepts essential to time-area calculation are explained and simple formulas for several different cases are introduced. Based on these formulas, a graphical example of the time-area consumed for a hypothetical commuter round-trip using three different modes demonstrates some of the quantitative measures and insights regarding transportation and urban land use to be gained through this approach.
