Safe Streets Act of 2017
Assembly Bill 342
Motor Vehicle Collisions are a Leading Cause of Injury Death and a Major Public Health Crisis
In the US, 40,000 people die annually in traffic collisions (i).
10% of these deaths are in California. Motor vehicle collisions are the:
#2 cause of injury deaths* for those under 5 years old
#1 cause of injury deaths for children and young adults
#2 cause of injury deaths for
adults and seniors
Speeding is the Major Factor in Severe Injuries and Fatalities
Vehicle speed is the strongest predictor of whether a person who is hit by a car is killed or survives a traffic collision. In the US, speeding was a contributing factor in 28 percent of crash deaths in 2014, resulting in 9,262 deaths (ii). The faster a car is traveling, the greater the risk of serious injury or death to those in and outside a vehicle in a collision (iii).
If a pedestrian is struck by a vehicle traveling 20 mph, they have a 90% chance of surviving.
The likelihood of survival is only 20% when a hit by a vehicle traveling 40 mph.
Seniors only have an 8% chance of survival if hit by a car traveling 40 mph.
Speeding Kills in San Francisco
AB 342 "The Safe Streets Act of 2017" introduced at Zuckerberg San Francisco General Hospital
On February 8th 2017, State and Local officials met for a press event to announce the introduction of Assembly Bill 342. AB 342 gives San Jose and San Francisco the authority to install automated speed enforcement (ASE) systems over a five-year pilot period in order reduce speeding and protect the safety of vulnerable travelers, such as children, the elderly, and bicyclists, in the two municipalities. Like emergency medical care, ASE is a life-saving tool to address dangerous conditions on our streets.

What is Automated Speed Enforcement?
In order to make our streets hospitable for all road users, drivers must be discouraged from traveling excessive speeds. Automated Speed Enforcement (ASE) is a safety technique that uses vehicle speed sensors and cameras to capture images of cars traveling excessive speeds. ASE is a proven tool to deter illegal speeding because the technology provides consistent and predictable enforcement of the speed limit. With ASE, cameras: (1) only activate when speeding (10 mph over the speed limit); (2) only can take photos of license plates, eliminating opportunity for bias; (3) operate at speed of light, and can detect speeding across multiple lanes of traffic. In addition, safety camera locations will be on the City(s) website and signed with the goal of slowing people down. A public education campaign will launch prior to operating the program so people know to expect it, and there will be a 90 day warning period prior to ticket issuance. The ticket cost is low ($100) and motorists will still be granted full protection under the law (opportunity to contest their ticket).
Automated Speed Enforcement Used Nationwide
While ASE may be a new technology in California, it is not new across the rest of the US. There are now 139 communities across 15 states and Washington DC that use it.
Communities that Use Automated Speed Enforcement Save Lives
Washington, DC found a 70% reduction in fatalities
Portland reported a 53% reduction in fatalities since program inception
Denver realized a 28% decrease in average speed
Chicago reported a 31% decrease in speeding vehicles
New York City reported a 13% decrease in collisions with injuries near cameras sites
Speed related collisions and severe and fatal injuries: San Francisco, 2012-2016
Between 2012 and 2016 in San Francisco, 239 people were severely injured and 25 people died in collisions where unsafe speed was a primary factor (vi).
Speed related collisions and severe and fatal injuries: San Jose, 2010-2014
Between 2010 and 2014 in San Jose, 197 people were severely injured and 19 people died in collisions where unsafe speed was a primary factor (vii).
