Speed Humps Sharply Reduce Risk of Kids Being Struck and Injured by Motorists

A comprehensive five year study by a team of Oakland, California doctors has found that children living on blocks with speed humps have a 53% to 60% lower chance of being injured or killed by motorists. This result is no surprise to T.A. For many years, we have strenuously advocated for more speed humps in New York City, especially around schools.

The study, “A Matched Case-Control Study Evaluating the Effectiveness of Speed Humps in Reducing Child Pedestrian Injuries” is featured in the April 2004 American Journal of Public Health. The study is particularly important because it is one of the few rigorous analyses performed in the United States on the effectiveness of speed humps in reducing pedestrian deaths and injuries. The doctors who conducted the study scrutinized emergency room records for five years and carefully mapped crash and speed hump locations, while correcting for income disparities between victims. The speed hump study was funded by the Oakland Pedestrian Safety Project, which is part of the city’s economic development and planning agency.

The project’s work has led to a sharp decline in Oakland’s pedestrian deaths and injuries. Oakland, which has a population of 400,000 people, installed 1,600 speed humps between 1995 and 2000. New York City, which has a population of 8.1 million people, has about 800 speed humps.
