59th Street Bridge, New York City, during August 2003 electrical blackout. (Source: Final Report DOT-VNTSC-FHWA-04-04).
Reliability is also very important in traffic operation. New York City’s roadway and rail system came to a halt on August 14, 2003, due to the Northeast Blackout. Approximately 11,600 signalized intersections and 413 train sets operating throughout the New York City subway system lost power, stranding over 400,000 customers.
The wind/solar hybrid roadway power system will provide a source of backup power for the transportation system, which will reduce the risk of blackouts in case of catastrophic events and significantly increase the reliability, efficiency, flexibility, and sustainability.
