Ok, the road is too straight and wide: difficult to for pedestrians and an invitation to speeding.

It’s interesting there is at least some parking on the side plus a center turn lane. So ….

1. bump outs at each intersection to narrow the road and setting aside a parking lane. Traffic will slow because the bottleneck and pedestrians will be more visible and have a shorter crossing.
2. The idiots called the center turn lane a median so make it so, partway. Instead of one continuous wide open turn lane, a raised median with cutouts for turn lanes. Now no one can drive there so you’re cutting dangerous driving, but you still have turn lanes. You constricted the road more so cars go slower. At this point you only have one driving lane in each direction.

Seems easy enough to make a noticeable difference with less effort. However, if you wanted to redevelop, there’s room to go for protected bike lanes and roundabouts (actual roundabouts with signs and painted lines, not just obstacles in the street.

And yes, speed bumps are the worst choice.
