This report from the Federal Highway Administration (FHWA) studied the effect of various traffic calming measures on pedestrian safety. It summarizes past research on speed humps, bulbouts, and roadway narrowing. The authors conclude that bulbouts and raised crosswalks can reduce motor vehicle speeds, and the combination of a raised crosswalk with an overhead flasher was most effective in encouraging motorists to yield to pedestrians. Although they found that motorists did slow down, the measures did not affect the pedestrians for whom motorists yielded. Also, the treatments usually did not have a significant effect on average pedestrian waiting time.
