Abstract:
The Newark City Subway Broad Street Extension project was typical of light rail projects in that it required continued coordination among several government entities, including New Jersey TRANSIT, New Jersey Department of Transportation, the city of Newark and Essex County. In this case, however, the project was often confronted by changes in existing physical conditions within or adjacent to the light rail transit (LRT) trackway. Virtually every traffic control issue was unique, requiring specific and individual treatment. These issues included: the type of transit priority to be granted at each location; the type of (transit) detectors to be employed; the traffic signal phasing and timing at each location; and the type of traffic control firmware to be utilized. Although several of these issues were decided in preliminary, ultimately, other factors required that each be revisited and reconfirmed or modified as the project advanced through final design and construction.
