Pedestrian safety: a road safety manual for decision-makers and practitioners Appendix 2 the equivalent of two narrower one-way streets instead of one wide two-way street. Landscaping can be used on medians but should be chosen carefully to ensure adequate sight distance between motorists and pedestrians, including children, wheelchair users, and others with reduced sight distance. Design of raised medians must also consider vehicle turning movements carefully so that motorists do not travel on inappropriate routes, such as residential streets, or make unsafe u-turns. Raised median designs must also accommodate pedestrians with visual impairments through use of tactile cues at the border between the pedestrian refuge area and the motorized vehicle roadway and for pedestrians in wheelchairs through the use of kerb ramps or cut-throughs. Raised intersections Raised intersections are intended to slow all vehicular movements through an intersection. They are built by raising the entire intersection to the level of the sidewalk. The crossings on each approach may also be elevated, so that pedestrians cross at the same level as the sidewalk, without the need for kerb ramps. Raised crossings can be an urban design element through the use of special paving materials. Detectable warning strips mark the boundary between the sidewalk and the street for pedestrians with vision impairments. Serpentine street A serpentine street uses a winding pattern with built-in visual enhancements. These allow vehicles to move through slowly and prevent fast driving. Landscaping can be used to enhance visual appeal and create a park-like atmosphere. Serpentine street design needs to be coordinated with driveway access and parking needs. Serpentine streets offer many advantages, but are more costly than other equally effective traffic calming strategies. Speed humps and speed tables A speed hump is a rounded raised area placed across the roadway. Speed humps are generally negotiated easily on bicycles and should be built through any bicycle lanes present on the roadway so that motorists do not swerve into the bicycle lane to avoid the hump. Flat-top speed humps are also referred to as speed tables. Woonerf Woonerf is a Dutch word that translates as ‘living street’. Typically used on residential streets, a woonerf is a space shared by pedestrians, bicyclists, and lowspeed motor vehicles. It is usually constructed with a narrow width and without kerbs or sidewalks. Vehicles are slowed by placing trees, parking areas and other obstacles in the street. Along with improving pedestrian safety, a woonerf creates a public space for social and possibly commercial activities, as well as a play area for children. A woonerf identification sign is placed at each street entrance. A woonerf must be constructed to allow access by emergency vehicles, school buses, and other service vehicles. 113
