How Much Time Is Wasted Sitting at Traffic Lights?

On average, people spend six months of their lives waiting on traffic
lights.

A significant amount of time is wasted sitting at traffic lights—on
average, six months of a person’s entire life is spent at red stop
lights, according to a time management study by Priority Management
Pittsburgh. Each year, approximately 36 hours are spent stuck in traffic
congestion in the US, as reported by the Texas Transportation Institute’s
2009 Urban Mobility report. However, larger cities, including Washington
DC, Los Angeles, and San Francisco, may experience an even higher amount of
wasted time in traffic at over 46 hours. In 2007, Americans wasted a total
of 4.2 billion hours sitting in traffic, or the equivalent of 500,000
years.
