The research project is a preliminary exploration into procedures, applications and effects of helicopter surveillance of commuter and freight railroad facilities in an urban environment. The project was conducted in the Philadelphia Metropolitan Area in the Spring and Summer of 1972 for the Federal Railroad Administration and with the cooperation of the Penn Central Transportation Company and the Reading Railroad. An attempt was made to document effects of the helicopter patrol and to provide insight into the requirements of a more exhaustive program to attain statistical validation of observed impact of helicopter use.
