"The fake speed humps are being installed at 100 junctions around Philadelphia, Pennsylvania as part of a campaign against aggressive driving."

"'The goal is to change the mindset,' said Philadelphia's chief traffic engineer Charles Denny."

"'The driver sees this in the roadway, and they think that it's some protrusion up out of the roadway, and not a perfectly flat surface. So they slow down before they drive over it.'"

"Accident data will be collected by the National Highway Traffic Safety Administration to see if the pioneering scheme actually does make the roads safer."
