In order to reach Vision Zero, engineering is a key consideration, along with education and enforcement. Our community has created an ad campaign alerting pedestrians to the danger of walking while distracted (usually by use of a smartphone) but it's resulted in little change in crash and injury rates. What are others doing to engineer a safer system? We can't "educate" our way out of all crashes, but we're also looking for low-cost and fast options to improve the street conditions given that our budget is already stretched to the breaking point.
