A curb bump out is also known as a curb extension.  These are generally placed at pedestrian crossing locations as a safety improvement.  By bumping out the curb line at a crosswalk, the traffic gets slower, the pedestrians are more visible to oncoming traffic, and pedestrians are clearly directed to these crossing locations which helps channel them to safer crossing locations.  As recommended by the 2007 Multi-Modal Transportation Study, curb bump outs are being installed throughout campus to enhance pedestrian safety.  Curb bump outs can be installed when there is a parking lane on a street, and when the MTD bus turning movements can still be accomodated.  Once installed, they also provide opportunities for campus beautification, through additional green space.
