Pedestrian safety. Most of Hampden is residential with a high foot traffic commercial street. And one lane roads. Cars should not be moving through area at speed or with priority.

Plus think of the driver POV on a right-on-red. The driver is most likely heavily focused on where oncoming traffic is coming: primarily to the left or possibly ahead (if oncoming traffic has a left turn). Depending on angles, the pedestrian could enter the cross walk in the driver's blind spot if their head is turned to the left.
