like an easy answer, it is often not enough by itself. Without any other changes, simply lowering the speed limit on a given stretch of road may have little effect on driver compliance. Speed limits, which are set below the speed that most motorists perceive to be reasonable for the given road, should be augmented with additional measures to improve compliance. While there are many things that can be done to help, the following are some design ideas for improving the walking environment.
Curb extensions can be a great way to help slow motorists down while shortening crossing distances for pedestrians. Curb extensions narrow the roadway and reduce the crossing distance by extending the sidewalk area into the parking lane. Curb extensions also help to make pedestrians more visible by bringing them out from behind parked cars. This helps both pedestrians and motorists better see each other. Curb extensions can also provide space for curb ramps, help to slow the speed at which vehicles can turn, and prevent motorists from parking on or near a crosswalk.
Pedestrian refuge crossing islands also work to help lower speeds and shorten crossing distances. Crossing islands are raised islands located in the middle of a street that narrow the travel lanes at that location and provide an auto free place for pedestrians to stop, mid-crossing. Crossing islands work by reducing
