As Gerald points out, there is some research that says traffic signals don't improve pedestrian safety---they may be worsening it. These studies are not only covered by people like Jeff Speck---who is an expert on walkability---but are greatly explained by Ben Hamilton-Baillie. It may sound counter productive, but green traffic lights disable an important mechanism in out mind that controls the hazards around us. If you remove the lights, you increase perceived risk and thus you improve safety. I understand that there is also a conflict between good transit and pedestrians. The lights would be useful for allowing faster speeds on the buses, and may be needed, but justifying them in the name of pedestrian safety may not be appropriate at all.
