There is nothing remarkable about this intersection; it is a prototypical arterial-arterial signalized intersection like many others in the Phoenix Metro area — this one is in the City of Tempe. Both streets are high-speed (45mph posted maximum limit); with two through lanes, a bike lane in each direction; in addition 
The increased risk posed by SUV (more generally, “Light trucks”) drivers on other road users has been pointed out before, many years ago. See e.g. 
The drumbeat to encourage bicyclists to always wear “hi-viz” (hi-vis, high-visibility, fluorescent) colored clothing — even in daylight — seems to become louder and louder. But it appears there is scant evidence suggesting any measurable safety improvement. The best I get when asking what evidence exists is something along the lines of “it can’t hurt”. (this has echos of the never-ending helmet wars;
