Toward a Methodology for Measuring the Security of Publicly Accessible Spaces

Abstract

Safety and security are essential components of urban public space management, particularly since September 11, 2001. Although security is necessary for creating spaces the public will use, making it a top priority is often criticized for restricting social interaction, constraining individual liberties, and unjustly excluding certain populations. This study examines legal, design, and policy tools used to exert social and behavioral control in publicly accessible urban spaces. Based on a review of the relevant literature and extensive site visits to spaces in New York City, we create an index that uses 20 separate indicators in four broad categories to quantify the degree to which the use of a space is controlled. Since comparable instruments do not exist, we propose our index be used to evaluate publicly accessible spaces. We suggest several potential applications useful in planning practice and for testing theories about public space.
