Access to Destinations: How Close Is Close Enough? Estimating Accurate Distance Decay Functions for Multiple Modes and Different Purposes

摘要: Existing urban and suburban development patterns the subsequent automobile dependence are leading to increased traffic congestion air pollution. In response growing ills caused by sprawl, there has been an interest in creating more “livable” communities which destinations brought closer one's home or workplace (that is, achieving travel needs through land use planning). While several reports suggest best practices for integrated use-planning, little research focused on examining detailed relationships between actual behavior mean distance various services. For example, how far will pedestrians access different types of destinations? How know if “one quarter mile assumption” that is often bantered about reliable? bicyclists cycle a bicycle only facility? do people drive their common retail needs? To examine these questions, this makes available survey data Twin Cities region. A primary outcome accurately robustly estimate decay models auto non-auto modes, also comment its applicability for: (a) travel, (b) accessibility measures incorporate information.
