I'm writing a scientific paper and I want a more concise phrase. What's the best phrase with the same semantics as a replacement with 'streets general natural surveillance', which means how much the pedestrians or residents can observe the street and its events and incidents?
If a street is straight and has no trees or shrubbery that would obstruct line-of-sight, we could say that the thoroughfare is open to view for pedestrians on the sidewalk as well as for operators of vehicles, and for anyone with a window that opens out onto the street. They all can see, to varying degrees, what is happening on the street. They have an open view of the street. You can refer to the street's openness to view or openness of view.
