"Crime prevention through environmental design (CPTED) is an approach to problem solving that considers environmental conditions and the opportunities they offer for crime or other unintended and undesirable behaviors. CPTED attempts to reduce or eliminate those opportunities by using elements of the environment to (1) control access; (2) provide opportunities to see and be seen; and (3) define ownership and encourage the maintenance of territory. This guide is a resource for understanding and using crime prevention through environmental design as a problem-solving tool. The guide explains the basic principles of CPTED and outlines a process for identifying problems, evaluating the physical environment, and identifying strategies that will remove or reduce opportunities for crime."
