Advanced Communication System for Application to Railroad Security

摘要

The addition of common radio frequency channels to the police communication systems of individual railroads serving a city, thus uniting, in effect, the existing police forces into one coherent unit, was considered to be a promising way to stem the amount of crime sustained by railroad companies. This concept was applied on a pilot basis to the Detroit, Michigan area, which is served by many railroad companies. To provide a measure for effectiveness, pertinent crime statistics were accumulated during equal time periods before and after the upgraded system became operational. An analysis of the data revealed that the use of this concept was very cost effective for reducing the number and severity of railroad crimes in the Detroit railroad yards.
