"The street design is the problem."
I've driven on that street many times. From what I've seen, the basic design is no different than nearby streets, such as Sheridan. Both are relatively narrow, two lanes of traffic in each direction, and narrow sidewalks abutting small homes.
Vehicle speed is not a conclusive factor when the basic problem is people walking across the middle of the street instead of using the marked crosswalks at intersections. As such, knowing the type of accident, and who was at fault, provides the data to make correct decisions regarding the street design.
Please explain why you feel the design of the street is faulty.
