BECAUSE OF THE PREPONDERANCE OF CRIME AND HARASSMENT ON RAPID TRANSIT AS OPPOSED TO SURFACE TRANSIT, RECOMMENDATIONS ARE DIRECTED TOWARD TEST DEMONSTRATIONS ON THE RAPID TRANSIT SEGMENT OF THE SYSTEM. ALL SUGGESTED IMPROVEMENTS ARE BASED ON SYSTEMATIC ANALYSES OF TRANSIT CRIME PATTERNS, RIDERSHIP TRENDS, A SURVEY OF PUBLIC PERCEPTION OF TRANSIT CRIME, PRESENT SECURITY MEASURES, AND GENERAL OPERATING PROCEDURES. PROFILES OF TRANSIT CRIME ARE DERIVED FROM AN 18-MONTH SERIES OF CRIME DATA COLLECTED ON THE SYSTEM. A CRIME-RIDERSHIP INDEX IS EMPLOYED TO MEASURE RISK TO PATRONS ON VARIOUS PARTS OF THE TRANSIT SYSTEM. PRESENT INADEQUACIES IN SURVEILLANCE AND RESPONSE CAPABILITY OF POLICE ARE DESCRIBED. THE QUESTION OF INCREASING MANNED PATROLS AS OPPOSED TO SUBSTITUTING ELECTRONIC OR MECHANICAL SYSTEMS IS EXAMINED FROM THE VIEWPOINT OF ASSURING PATRONS OF RAPID PROTECTIVE RESPONSE SHOULD AN EMERGENCY ARISE. A PUBLICLY ACTIVATED CLOSED-CIRCUIT TELEVISION SYSTEM IS OFFERED AS ONE MEANS OF ADDRESSING THE SECURITY NEEDS ON HIGH-RISK PORTIONS OF THE RAPID TRANSIT NETWORK. (AUTHOR ABSTRACT)
