An important consideration in urban and regional planning is where to locate facilities providing services. Location models are typically used to support facility siting decisions. This paper develops general models that simultaneously addresses issues involving potential demand as a function of distance, coverage range, and partial regional service in facility siting. The developed models are general in that they can be utilized for siting both desirable and undesirable facilities. Application results are presented for a discrete linear model to locate park-and-ride facilities (desirable) and recycling facilities (undesirable) in Columbus, Ohio. The findings illustrate the flexibility and usefulness of the developed modeling approach for addressing a wide range of planning issues.

Park‐and‐ride services are an integral component of many public transit systems in the United States. A necessary step when analyzing and planning for such services is to delineate catchment areas for park‐and‐ride facilities. Previous approaches for delineating catchment/market areas are either problematic or have unrealistic data requirements. This paper develops a Geographic Information System (GIS)‐based approach for delineating market areas. The detailed approach simultaneously accounts for park‐and‐ride facility accessibility and user travel direction. It is shown that the developed approach performs better than existing approaches. Further, this paper provides a detailed and formal description of these approaches, which should facilitate interpretation and implementation in a GIS environment.
