In 2015, an urban planner in Arkansas created this meme, Which street is safer?
They're both residential streets with a 20 mile per hour speed limit.
But while this street was designed to be more forgiving to drivers, this is actually the safer street.
So, why have we been building so many streets like this one over the past 50 years?
In 2017, traffic deaths hit a 25-year-high of 40,000 fatalities.
Six thousand of those killed were pedestrians.
Cities across the country are trying to reduce traffic fatalities with safety campaigns.
One of the keys to the whole problem might be a flawed mid century design philosophy.
There was a big transportation safety movement in the 1960s.
This is when we saw the development of airbags and crash tests.
