Actors in urban development use and respond to many plans made by organizations, both public and private, at different times with different purposes and scopes. Coping with such networks of information and constraints presents an opportunity to advance development of planning support systems (PSS). The Plans and Regulations Information Tool (PaRIT) is a computing interface that enables spatial queries to identify and access plans and regulations. We illustrate the capabilities of PaRIT in applications to a light rail project in Maryland. Choices made in developing PaRIT demonstrate a feasible approach to accessing a network of plans and highlight opportunities for advances in PSS.
