A METHODOLOGY FOR DEVELOPING SECURITY DESIGN CRITERIA FOR SUBWAYS

THE REPORT CONTAINS 31 SPECIFIC DESIGN MODIFICATIONS FOR STATIONS AND TRAINS TO POTENTIALLY ELIMINATE COMMON ASPECTS OF THE SUBWAY ENVIRONMENT WHICH ABET CRIME AND INHIBIT ITS PREVENTION. IN ADDITION, 16 TYPES OF CRIME AND HARRASSMENT RANGING FROM SUCH MISDEMEANORS AS LOITERING OR DISORDERLY CONDUCT TO RAPE AND HOMICIDE ARE DELINIATED. EACH IS DEFINED WITHIN THE CONTEXT OF AN URBAN PUBLIC TRANSIT SYSTEM. BASED ON THESE DATA, THE PHYSICAL FACTORS WHICH DELIMIT THE PROBABILITY OF CRIME AND HARRASSMENT IN SUBWAYS ARE (1) SPACE AND LOCATIONS; (2) DISTANCE AND ACCESS TO OPEN SPACE; (3) VISIBILITY; (4) SCALE; (5) MASTERY, CONTROL, AND OWNERSHIP OF PROPERTY; AND (6) CONDITIONS OF THE SURROUNDING URBAN ENVIRONMENT. THESE FACTORS COMBINED TO YIELD 23 SEPARATE DATA INPUTS TO A SYSTEMATIC METHODOLOGY FOR PREVENTING CRIME BY CONTROLLING PHYSICAL DESIGN FACTORS IN SUBWAYS AND STATIONS. IN ADDITION, 15 NON-PHYSICAL DATA INPUTS WERE DEVELOPED WHICH REFLECT RELEVANT QUESTIONS ABOUT SPECIFIC INCIDENTS. THE LATTER ARE IMPORTANT IN RECONSTRUCTING BEHAVIORAL PROCESSES AND THE ATTITUDINAL CLIMATE IN WHICH CRIME CONTROL METHODS WOULD BE IMPLEMENTED. THE REPORT EXAMINES EACH OF THE DATA INPUTS AT LENGHTH ALONG WITH CITATIONS FROM ORIGINAL CASE MATERIAL. SUBSEQUENT PHASES OF THE METHODOLOGY ARE OUTLINED IN DETAIL. HAVING NOTED THE OPEN-ENDED INVENTORY OF CRIMES AND ENVIRONMENTAL FACTORS, A SECOND STAGE OF THE PROPOSED METHOD EMPLOYS COMPHREHESIVE SURVEYING PROCEDURES TO ANALYZE THE INTERRELATIONSHIPS AMONG THESE VARIABLES. THREE SURVEYS ARE RECOMMENDED TO COLLECT RELEVANT DATA CONCERNING ACTUAL INCIDENTS OF CRIME AND HARRASSMENT, CHARACTERISTICS OF SUBWAY STATIONS, AND PHYSICAL AND NON-PHYSICAL CONDITIONS ABOARD TRAINS. DETAILED SURVEY INSTRUMENTS AND QUESTIONNAIRES ARE REPRODUCED. EMPIRICAL METHODS ARE INCLUDED FOR CORRELATING SURVEY DATA TO DETERMINE WHICH FACTORS ARE MOST PREVALENT DURING THE OCURENCE OF DIFFERENT CRIMINAL ACTIVITIES. THE EQUATIONS DERIVED WOULD YIELD OPTIMUM RECOMMENDATIONS FOR SUBWAY DESIGN BY SUGGESTING THE RELATIONSHIP BETWEEN PHYSICAL AND NON-PHYSICAL VARIABLES AND SUBWAY CRIMES. THE REPORT DOES NOT ATTEMPT TO EXPLORE SOCIAL FACTORS IN THE OVERALL URBAN SYSTEM, BUT RATHER, SEEKS TO DEVELOP A SCHEME WITH WHICH TO FASHION ANTI-CRIME SUBWAY DESIGNS. /UMTA/
