  • Traffic Calming
    SECTION 1, CHAPTER 6 Traffic Calming 6.1 Introduction 6.1.1 What is Traffic Calming? According to the Institute of Traffic calming deals with neighborhood traffic Transportation Engineers, traffic issues comprehensively using the “three E’s,” calming is the “combination of Education, Enforcement, and Engineering, to slow mainly physical measures that reduce the negative effects of or reduce motor vehicle traffic and improve motor vehicle use, alter driver safety for pedestrians and bicyclists. A fourth “E,” behavior and improve conditions enhancement, is used to improve area aesthetics for non‐motorized street users.” and soften the look of physical installations. Education provides neighbors with information about how they as motorists can help to ease traffic impacts in their community through changes in behavior and attitudes, and informs them about neighborhood traffic management activities and opportunities. Enforcement enlists the assistance of the Police Department to focus enforcement efforts in key areas. Engineering and planning encompasses both traditional traffic management measures as well as newer approaches, such as traffic calming. All three are important components in dealing effectively with neighborhood and community‐wide traffic issues. Modern traffic calming began as a grassroots movement in the late 1960’s which started with the Woonerf developments in the City of Delft, the Netherlands. Woonerven, or “living streets,” are residential streets where speeds are drastically reduced through reconstruction and space is shared between vehicles and pedestrians. Traffic Calming 1.6‐1 In the United States, Seattle, Washington was an early pioneer in area‐wide traffic calming with neighborhood‐wide demonstrations in the early 1970’s.
