  • John Hirsch Place – Winnipeg’S First Woonerf
    John Hirsch Place – Winnipeg’s First Woonerf As part of the City of Winnipeg’s Northeast Exchange District Renewals project, WSP Canada Group Limited was contracted to redesign John Hirsch Place as a unique shared space roadway in Winnipeg. The project involved the reconstruction of John Hirsch Place in Winnipeg’s historic exchange district and redesigning the right of way to a curbless shared street based on the Dutch ‘Woonerf’ (living street) model, which involves traffic yielding to pedestrian activity and significant landscaping to enhance the pedestrian environment. The curbless design was used to avoid defining areas and boundaries that restrict pedestrian movement but rather allow pedestrians to move freely within the site. Limited parking within the roadway is available, and vehicles are slowed by traffic calming measures such as bollards, narrow path of travel, and limited sight distance to discourage a large volume of vehicle traffic and enhance pedestrian safety and environment. The project is notable for its links to the district’s cultural context, technical innovations, and quality of design. To accommodate the significant landscaping along John Hirsch Place, a soil retention system was installed to provide uncompacted soil volume necessary for tree growth and provide opportunity to greatly increase plantings and trees in the public right of way, while not restricting the roadway for all road users. Strata Cells, capable of withstanding vehicular traffic and pavement loads, were placed beneath the roadway due to the proximity of existing trees to the roadway that required additional soil volume. Stormwater enters the systems along the roadway through a series of catch basins to reduce loading on a combined sewer while providing water for the tree roots.

  • Shoreline EDM Section 12.10 Woonerf Attachment C
    Proposed DA for Shoreline Place - Att. C - Shoreline EDM Section 12.10 Woonerf Attachment C Shoreline Engineering and Design Manual 12.10. Woonerf A woonerf (also known as a home zone, living street, or shared street) is a street that facilitates pedestrian, bicycle, and vehicular traffic within a shared space. Woonerfs typically lack separate pavement and include a variety of surface treatments, bollards, street lighting, and landscaping to define a shared space. Woonerfs can be private or public and are intended to be designed to meet the needs of the immediate community. The following standards are generalized and provide a starting point for woonerf design. Each woonerf is a unique shared space. Woonerfs designs should achieve the following objectives: A. Shared pedestrian, vehicular, and bicycle traffic; B. Safe transitions for between woonerfs and standard facilities; C. Traffic calming measures, such as sitting areas, planters, parking spaces, and bollards; and D. ADA-compliant access. Woonerf design requirements include the following: A. Entrance/Exit: 1. The international woonerf sign is required at all entrances and exits. Informational signs may be placed under the international woonerf sign. 2. Traffic calming measures may be required at entrances and exits. B. Designated Spaces: 1. The design shall not give the impression of a roadway and sidewalk. 2. To designate pedestrian-only spaces, the use of bollards, landscaping, and other protection are encouraged. Curbs are not allowed. 3. Parking and/or loading spaces are acceptable. Parking spaces shall be distinguished by pavement markings, surface treatments, or other means. C. Surface Treatments: 1. The use of a variety of surface treatments is encouraged.

  • Residential Street Standards & Neighborhood Traffic Control
    Residential Street Standards & Neighborhood Traffic Control: A Survey of Cities' Practices and Public Officials' Attitudes Eran Ben-Joseph Institute of Urban and Regional Planning University of California at Berkeley Abstract The failure of the local street system to provide livability and safety in the residential environment can be seen in the application of neighborhood traffic management programs by local authorities to mitigate traffic problems. In order to further identify the extent of the conflict associated with "livability" and geometrical design of residential street, the following issues are examined: (1) Existing and proposed residential streets standards and regulations as practiced by various cities and their evaluation by public and city officials. (2) Traffic problems associated with residential streets and their mitigation through traffic management and control programs. Data are collected from Public Works and Traffic Engineering Departments of 56 Californian cities and 19 cities nation-wide. The findings show that most cities are still adhering to published street standards as recommended by different professional and federal organizations. Although some city officials see the need to amend certain aspects of their regulations and create a more flexible framework for street design, most of them believe that the current practice is satisfactory. Yet, the extant of residents' complaints about traffic problems on their streets might indicate an inconsistency between professional practice, as manifested in street design, and its actual performance as experienced by the residents. This can also be seen in the application of traffic control devices used by local authorities to mitigate these problems of which the most common are the installation of speed humps and 4-way stop signs.

  • What Is a Woonerf Street?
    Attachment C What is a Woonerf Street? • Definition: A Woonerf Street is designed for both vehicular and non-vehicular traffic, such as pedestrians and cyclists, and can be used as a social gathering or recreation space. Pedestrians and cyclists take precedence in the use of the street. The access for all modes is accommodated on the same surface, and not differentiated by grade separation or other barriers. Woonerfs include traffic calming measure to ensure safe co-existence of vehicles and non- vehicular users. Landscaping features, including patterned paving, planters, trees, benches, or bollards, may enhance pedestrian safety and use. • Purpose: Woonerf Streets provide an alternative cross-section for circulation of multiple user groups. This street design accommodates vehicle traffic, and prioritizes pedestrian and bike movement, as well as recreation. The Woonerf Street option does not require two-lane street construction with parallel sidewalks separating user groups. The Woonerf Street accommodates multi-modal uses within the same street section. Woonerf Streets include traffic-calming strategies and landscaping amenities to address the safety of non-motorized users. Children may feel safe enough to play in a Woonerf. Drivers should be more alert and drive with increased caution. All users should feel welcome and safe. The Woonerf Street option is intended to provide a balanced integration between cars and people. • Alternative Compliance: The Traffic Engineer and the Planning Director may approve an alternative design that meets or exceeds the Woonerf Street standards if, and only if, the variation is from the required street width. Woonerf in Downtown Anchorage by the Municipality of Anchorage City Hall Photo - Kristine Bunnell • Design Elements: The Woonerf Street shall include the following design elements: a.

Image: Hamilton 2000 1 | TRAFFIC RESTRICTED STREETS Streets for People Woonerfs are streets built with high quality urban design where the boundary between people space and car space is intentionally blurred. In doing so, the pedestrian space is extended from the sidewalk, and into the traffi c zone. Whereas in a normal street, pedestrians are made to feel like guests in the cars space when they cross the street, woonerfs reverse this axiom.

  • Transportation Is a Key Component of Everyday Life
    6. Multimodal Connectivity & Accessibility 6 Overview Transportation is a key component of everyday life. The places it connects people to and how safe, predictable, and reliable it is affects community quality of life. Transportation costs are also the second largest household expense after housing. It is for these reasons that sustainable, connected, and integrated transportation is fundamental to sustained success and livability of the city. Transportation Impacts Transportation not only impacts the way people move in a city and access day-to-day needs but also has a significant impact on the shape of communities. The transportation network’s design directly affects how people use it. Streets designed with the sole purpose of moving vehicles – with wide travel lanes and no sidewalks – will only attract more cars and the land uses that serve those needs. On the other hand, transportation networks designed to serve people – with bike facilities, wide sidewalks, and other pedestrian accommodations – will attract more pedestrians and bicyclists and support active, livable communities. The transportation network should both inform and respond to the surrounding context, and provide safe accommodations for all users. In order to achieve the vision and goals of this Plan, it is important to focus on enhancing pedestrian, bicycle, and transit access throughout the West End. Example of a well-balanced multi-modal street. 6-1 Mode Share Travel in Falls Church already includes walking, bicycling, and transit use, as well as driving. The current mode split between different modes of travel, for commute trips originating in the city differs fairly significantly from the mode split for all daily trips – trips to work, the gym, the store, to visit friends, etc.
