Signal System Design Standards
New York City Transit
Brooklyn, NY
As part of a major review of the existing conditions of the
signal system of the nation's largest rail transit system,
Interactive Elements, as a subcontractor to Parsons Brinckerhoff,
prepared a computerized database of the physical characteristics
of the signal system of the NYCT Subway. Responsibilities
included performing train performance calculations; documenting
signal locations in non-compliance with current standards; and
providing recommendations and prioritizations for improvement.
The firm was also responsible for writing the final signal
standards design philosophy document. This project was one of
several major new technology signal initiatives that the firm
participated in at NYCT (see IEI projects 269, 306, and 525).
