Vulnerable Road Users [VRU] include pedestrians, bicyclists and motorcyclists. Among these, pedestrians are certainly in very serious danger in California.
“Just 10 years ago, 17 percent of California’s roadside [sic] fatalities involved pedestrians. That number has since grown to 25 percent…. According to the California Office of Traffic Safety, preliminary results show a record-high 900 people died [in 2016] across the Golden State – an increase [of more than five percent] from 852 in 2015.“
Many experts consider that the use of smartphones, etc., both by drivers and other road users is a major factor in such elevated numbers of road deaths.
