Roosevelt Island Tramway System Assessment

摘要

The Roosevelt Island Tramway serves as an urban transit system in New York City. The system is based on conventional cable technology and connects a new urban community on Roosevelt Island in the East River to Manhattan. This system is the first urban transit application based on aerial tramway (cableway) technology and has been in service since May 1976. The goals and objectives of this assessment were to provide information with regard to: (1) factual engineering and operating data concerning the technology which can be used in the planning and implementation of similar cable systems; (2) descriptive information on system performance, economics and ergonomics, which can be used in planning for the assessment of the feasibility of subsequent system installations; and (3) design, development, and implementation experience with cable technology, to determine what has been learned and how future urban installations can most effectively be carried out. The report findings are based on literature searches, Roosevelt Island Tramway documentation, analyses of system records and logs, and observations and interviews during site visits. The report provides factual engineering information concerning the technical subsystems. System operational performance, system assurance, human interface, safety and security were assessed; an evaluation of the distribution of capital and operating maintenance costs is presented; and system development and implementation history are summarized.
