Miami-Dade County, FL to Discuss Report on Methods of Emergency Power to Traffic Signals After Hurricanes
The Commission will discuss a report on methods of providing backup power to traffic signals. The Department of Transportation and Public Works (DTPW) initiated this analysis September 2017 immediately after Hurricane Irma. During Hurricane Irma recovery efforts, to best allocate resources, the DTPW prioritized roadway intersections based on their size and number of lanes. DTPW worked with Florida Power and Light (FPL), the Florida Department of Transportation (FOOT) and Miami-Dade County Police to deploy generators, as well as temporary stop signs at critical intersections that had lost power. Of 2,887 signals, 2,232 were offline the morning following the storm, with the majority being without power, and six signals were severely damaged. Within 14 days of the storm, 95 percent of all signals were restored and operational. Immediately after the storm, DPTW began exploring options for maintaining power to signals.
02/04/19 The Commission will hold a discussion at the 2/05/19 meeting.
