The city's traffic fatality rate declined by roughly 50 percent between 1996 and 2006. Key to that result was an initiative to address traffic deaths and homicides in tandem.
More than 40,000 Americans were killed in traffic last year, according to new estimates from the National Safety Council, the worst toll in a decade. The U.S. transportation system claims far more lives each year than peer countries. If America achieved the same fatality rate as the UK, more than 30,000 lives would be saved each year.
