Improving the Reliability and Resiliency of Traffic Signals in an Urban Environment: Cost–Benefits in Washington, D.C.

The Washington, D.C., signal system experiences an average of 330 outages each year, lasting for a total of 3,850 hours. According to traffic signal data analyzed from 2008 to 2013, extreme weather events accounted for the largest proportion of these outages. The District Department of Transportation (DOT) has developed two strategies to address signal outages, back up generators and battery backups. This article looks at the benefits and cost savings of these two strategies.
