Automated enforcement technology is an important Vision Zero tool for improving safety on our streets

by Jessica Vargas on February 2, 2018

On Valentine’s Day, The House Transportation & Energy Committee voted down HB 18-1072, the automated enforcement ban that would have prevented municipalities from using photo speed enforcement and red light cameras – technology proven to save lives. So we wanted to say a huge thank you to everyone who took action and asked their representatives to support safe streets! We’d also like to thank the eight legislators who voted NO on HB 18-1072!

Last year at our Valentine’s Day Love-In, the Vision Zero Coalition launched the Safe Speeds for Denver campaign, calling upon the City to address the inherent dangers of unsafe speeds. Thanks to our advocacy, Denver’s Vision Zero Action Plan includes a strong emphasis on speed management, including increased use of automated enforcement along the High Injury Network, the 5% of Denver streets where half of all traffic fatalities occur.

The City’s ability to implement such a strategy would have been in jeopardy, thanks to the Colorado state legislature: House Bill 18-1072 would have banned municipalities from using photo speed enforcement and red light cameras – technology proven to save lives. The passage of this bill would have been a huge setback for Denver’s efforts to reduce deadly vehicle speeds.

Decades of research have found that drivers traveling at higher speeds are less likely to see someone walking or biking, are less likely to yield, have less time to stop, and if a crash occurs, it is much more likely to be fatal. A pedestrian struck by a car traveling 40 mph has a 73% chance of dying or suffering a life-altering serious injury, compared to only a 13% chance if the car is traveling 20 mph.

Automated enforcement is a proven technique used worldwide to reduce traffic injuries and fatalities, and when deployed effectively actually results in fewer citations as safer travel speeds and behaviors become the norm. A review of 28 U.S. and international studies found in areas with speed cameras:

  • All crashes decreased 8% – 49%
  • Injury crashes decreased 8% – 50%
  • Fatalities and serious injuries decreased 11% – 44%
