accommodate the turning movement of larger vehicles or an intersection with no pedestrian traffic (for example, in an industrial area) versus a densely populated area. Traffic Calming Traffic calming was mentioned in several of the interviews, with four traffic calming measures being specifically mentioned: bulbouts (or neckdowns), roundabouts, speed tables, and on-street parking. The objectives of traffic calming include reducing traffic speeds, reducing traffic volumes, and facilitating the shared use of the roadway by different types of users (including both motorized and non-motorized). All of these objectives contribute to pedestrian safety, but speed reductions in particular can increase pedestrian safety considerably. A good in-depth source of information on the design and impacts of different traffic calming measures is the ITE “Traffic Calming: The State of the Practice” (Ewing, 1999, available on line at the Institute of Transportation Engineers website: www.ite.org). This section describes first, traffic calming programs that combine multiple traffic calming measures in one neighborhood or area and second, individual traffic calming measures. There are tables that indicate the effectiveness of the traffic calming measures in reducing speed and volumes at the end of the traffic calming section.. Traffic Calming Programs A set of programs aimed at calming the traffic have been adopted at various places around the world. Such programs include: Community Streets, “Woonerf,” Play Streets, transit malls, and area wide traffic restrictions: Community Streets: In Japan traffic calming strategies have been directed toward community streets, which rely on measures such as speed humps, bulbouts, chicanes, and other devices (see below for descriptions) to slow down motor vehicle traffic. Roadpia (short for Road Utopia) is neighborhood-wide installations of community streets that give priority to pedestrians and cyclists. The combination of traffic calming devices was effective in reducing traffic, vehicle speeds, and collisions (See Sriver and Kwon, 1999). Woonerf: The Netherlands developed the concept of “woonerf” (a Dutch word meaning roughly street for living) based on the residential yard (Kraay, 1976). These are areas where the physical and visual treatments of the public right-of way create a pedestrian-oriented area. Only local traffic is allowed to use the roadway and all modes are “forced” to travel almost as slow as the slowest mode (the pedestrian) through design features, such as special paving materials, lack of curbs, trees planted in the street, and street parking. (See example at: http://www.walkinginfo.org/de/curb1_print.cfm?codename=32d&CM_maingroup=TrafficCalmi ng ) Transit Malls with Shared Use of Pedestrian-Oriented Space: A study of crashes occurring before and after implementation of transit malls in Philadelphia and Minneapolis, showed nonpedestrian collisions decreasing sharply on transit malls with no evidence of an increase on NYMTC Pedestrian Safety Study 64
nearby streets. Whereas Bus-pedestrian conflicts are much higher on transit malls than on other streets, they have not resulted in a higher number of bus-pedestrian collisions. Areawide Traffic Restrictions: Areawide traffic restriction plans have been employed in Upsala, Sweden, entailing closing streets to vehicular traffic, using one-way flow on bypasses, and bus-only streets. Risk for pedestrians within the restricted area declined by 29 percent. However, risk on the streets outside the restricted area increased although by only 12 percent. (Lovemark, 1974 and Brownfield, 1980, cited in Campbell et al., 2004). Traffic Diversion: Traffic diversion can be made by street closures, diverters, and signs restricting access, either during the peak travel hours or on a 24-hour basis. These projects are designed to shift traffic off of a neighborhood street that is suffering from cut-through traffic onto other streets. If these “ other streets” are major streets or arterial roads (that is, not other residential streets), the project generally can be considered successful. Traffic diversion projects often limit resident access, as well as for their guests and service vehicles. Play Streets: Play streets entail closing, usually for a period of several hours, a neighborhood street to allow children to use it as a playground. Play streets have been employed in the United States in center city neighborhoods with few parks to provide safe play areas. A series of interview studies at 20 sites in Philadelphia and New York City found play streets to be effective in eliminating traffic and parking. (See example at: http://www.walkinginfo.org/pedsafe/popup4.cfm?codename=34e) Traffic Calming measures Gateways: Entrance and exit symbols such as “gates” into/out of a city are widely utilized in Europe to visually inform drivers of a change in driving environment such as speed limit, pedestrian and/or bicycling activity. Entrance gates also offer an aesthetic effect that welcomes visitors and drivers to the city or a neighborhood and acknowledges them as they leave. Such entrance and leaving gates would be most beneficial for major roadways that enter well-designated cities. In densely developed areas such as most of the NYMTC region, the boundaries of the cities and villages are often not clearly distinguishable. However, it is still possible to integrate similar “gates” on roadway sections that warrant speed and/or volume reduction or to indicate a transition from one type of street to another. Examples may include business districts, dense residential areas, and school areas. Additional gateway examples can be found in Brewer et. al. Figure 5.8. Gate at City College of New York (2001).
