"This report examines the measures used by the four case study transit systems and the conditions under which they are most likely to be effective. It is intended that this information will be useful to other transit systems which may re-evaluate their security programs and consider additional measures. The study was limited to bus systems. Certain transit security measures are common to all four transit systems...There are unique aspects to each city's program. The organization of Detroit's undercover police operations has been used as a model by many other cities; Los Angeles has demonstration projects using sophisticated equipment; Seattle has a stress-management program for its bus operators; and the Pittsburgh system's small but effective police force enhances operators' and passengers' perceptions of security by responding to operator and passenger reports of problem areas. This section provides an introduction to the problem of transit crime and the security measures taken to combat it. Section 2 describes the transit security programs in the four selected cities, the case studies of this report. Section 3 describes and compares the methods used to police bus transit systems. Section 4 examines the surveillance and communications equipment used by the four systems. Section 5 deals with school and community education programs and training of operators. The comparative costs of the various measures are discussed in Section 6 and Section 7 discusses the public's perception of transit crime. Section 8 summarizes the effectiveness of the measures and presents recommendations based on the data collected."
