Pedestrian signals help <br />accommodate pedestrian crossings on some <br />high-volume or multilane roads. <br /> <br />• Reducing the effective street crossing distance for pedestrians by narrowing the roads or by providing <br />curb extensions (figures 34 and 35) and/or raised pedestrian islands at intersections. <br /> <br /> <br />Figure 34. Curb extensions at midblock Figure 35. Curb extensions at intersections <br />reduce crossing distance for pedestrians. locations reduce crossing distance for <br />pedestrians. <br /> <br />Another option is to reduce four-lane undivided road sections to two through-lanes with dual left-turn <br />lanes or left-turn bays. Reducing the width of the lanes may result in slower speeds in some <br />situations, which can benefit pedestrians who are attempting to cross the street. This creates enough <br />space to provide median islands. The removal of a travel lane may also allow enough space for <br />sidewalks and/or bike lanes. <br /> <br />• Installing traffic-calming measures may be appropriate on certain streets to slow vehicle speeds <br />and/or reduce cut-through traffic, as described in a 1999 report titled Traffic Calming: State of the <br />Practice.(24) <br /> <br />Traffic-calming measures include raised crossings (raised crosswalks, raised intersections) (see figure <br />36), street narrowing measures (chicanes, slow points, “skinny street” designs), and intersection <br /> 56
