You can take a look at the map of West Hudson Bldv[1]. It cuts the area in half with a single crossing point on the road. Try asking google how to get to the Philips Center from anywhere north and google will tell you to cross at West Hudson and Echo, an intersection with no lights and no crosswalk. The author is certainly using hyperbole to make their point, but there is no question this road was not well designed for foot traffic. Boulevards like this often have people driving faster than the speed limit and not expecting people. There is tree cover that makes spotting cars in the distance difficult.
These things are simple facts about the road. They would have been known when it was designed and they massively raise the risks for pedestrias as compared to alternate designs. Splitting hairs in the sense that the designers did not "want" to endanger people is hyperbolic as the article. The intent is less important than the effect.
