Sharraxaadda

From 117th to 119th and Sheridan Ave. There are drivers who speed down Sheridan as if it were a raceway. Not the normal once in a while minor speeding, but at least 40-50 mph. They blow the stop sign on 118th St. It is a continuous issue, there are children crossing the street and it is dangerous for residents. Numerous times residents would be unloading groceries and these speeders scare them as they drive too close and fast. There are a lot of children, handicap and elderly residents who are unable to move out of the way quickly. Is it possible to install speed bumps?
