Visual preference survey

Last updated

A visual preference survey is a technique for obtaining public feedback on physical design alternatives. It is often used when designing zoning codes, planning redevelopment, and conducting urban planning research.

The survey consists of a series of images that participants must score according to their preference. The images may be actual photographs or computer-simulated images depicting potential urban environments. [1] The participants' input is then used to make decisions about the future built environment.

This technique was developed by urban planner Anton "Tony" Nelessen in the late 1970s, [2] and it grew in popularity during the 1990s. The method has been criticized on the basis that lighting, weather, and background activities might influence preferences. In part this is corrected by using simulated imagery, [3] but simulations themselves may be misleading when compared with actual photographs. Recent plans utilizing visual preference surveys include Denver, [4] Topeka, [5] New Castle, [6] and Orlando. [7] There are also international policy reforms and movements seeking to include visual preference surveys in the planning system. The United Kingdom has included visual preference surveys as a preferred engagement tool under the National Model Design Code, [8] and Street Level Australia has advocated for their use in the development of Pattern Books in New South Wales, Australia.

Criticisms of Visual Preference Surveys

Visual Preference Surveys have been criticized for potentially eliciting inaccurate measurements of a communities preference. As planner Reid Ewing has noted , “when you show citizens stark images of new suburban subdivisions or strip centers versus beautified images from America’s finest small towns, the outcome is predictable and largely meaningless.”

For accurate results, a visual preference survey must adhere to sound research design: It must be specifically tailored to the community and location, generated after multiple discussions and field investigations and photographic reconnaissance, and address eight or more related categories of visual and spatial characteristics.

Effective visual preference surveys are precise in exploring which variables they are attempting to measure, whether it be street trees, bike lanes, crosswalks, or any number of proposed changes. Nelessen and other practitioners have addressed this issue through the use of simulated or manipulated imagery using Adobe Photoshop or any number image manipulation software. In practice, this may involve taking exactly the same picture, yet adding a single element to the second picture to gauge community reaction to a proposed change. For example, visual preference surveys for locations such as Topeka, Princeton, and Journal Square contain several such images - one untouched image contrasted with exactly the same picture except with a single new element added, such as pedestrians, a narrower street, a median with greenery or other design elements. In such instances, higher scores for the second, doctored image provide a more reliable gauge for the aesthetic preferences of a community. [10]

Transportation planning is the process of defining future policies, goals, investments, and spatial planning designs to prepare for future needs to move people and goods to destinations. As practiced today, it is a collaborative process that incorporates the input of many stakeholders including various government agencies, the public and private businesses. Transportation planners apply a multi-modal and/or comprehensive approach to analyzing the wide range of alternatives and impacts on the transportation system to influence beneficial outcomes.

The City Beautiful movement was a reform philosophy of North American architecture and urban planning that flourished during the 1890s and 1900s with the intent of introducing beautification and monumental grandeur in cities. It was a part of the progressive social reform movement in North America under the leadership of the upper-middle class, which was concerned with poor living conditions in all major cities. The movement, which was originally associated mainly with Chicago, Cleveland, Detroit, Kansas City and Washington, D.C., promoted beauty not only for its own sake, but also to create moral and civic virtue among urban populations.

<span class="mw-page-title-main">Land-use planning</span> Process of regulating the use of land by a central authority

Land use planning is the process of regulating the use of land by a central authority. Usually, this is done to promote more desirable social and environmental outcomes as well as a more efficient use of resources. More specifically, the goals of modern land use planning often include environmental conservation, restraint of urban sprawl, minimization of transport costs, prevention of land use conflicts, and a reduction in exposure to pollutants. In the pursuit of these goals, planners assume that regulating the use of land will change the patterns of human behavior, and that these changes are beneficial. The first assumption, that regulating land use changes the patterns of human behavior is widely accepted. However, the second assumption - that these changes are beneficial - is contested, and depends on the location and regulations being discussed.

Maestro (software) was a free program released by NASA to allow users to view photos and daily progress of the Spirit and Opportunity rovers. It served as an activity planner for Mars that utilized a combination of 2D and 3D visuals to track the movement and missions of the Spirit and Opportunity rovers in 2004.

In computing, a mouseover, mouse hover or hover box is a graphical control element that is activated when the user moves or hovers the pointer over a trigger area, usually with a mouse, but also possible with a digital pen. Mouseover control elements are common in web browsers. For example, hovering over a hyperlink triggers the mouseover control element to display a URL on the status bar. Site designers can define their own mouseover events using JavaScript or Cascading Style Sheets.

A Form-Based Code (FBC) is a means of regulating land development to achieve a specific urban form. Form-Based Codes foster predictable built results and a high-quality public realm by using physical form as the organizing principle, with less focus on land use, through municipal regulations. An FBC is a regulation, not a mere guideline, adopted into city, town, or county law and offers a powerful alternative to conventional zoning regulation.

Placemaking is a multi-faceted approach to the planning, design and management of public spaces. Placemaking capitalizes on a local community's assets, inspiration, and potential, with the intention of creating public spaces that improve urban vitality and promote people's health, happiness, and well-being. It is political due to the nature of place identity. Placemaking is both a process and a philosophy that makes use of urban design principles. It can be either official and government led, or community driven grassroots tactical urbanism, such as extending sidewalks with chalk, paint, and planters, or open streets events such as Bogotá, Colombia's Ciclovía. Good placemaking makes use of underutilized space to enhance the urban experience at the pedestrian scale to build habits of locals.

<span class="mw-page-title-main">Urban planning</span> Technical and political process concerned with the use of land and design of the urban environment

Urban planning, also known as town planning, city planning, regional planning, or rural planning in specific contexts, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks and their accessibility. Traditionally, urban planning followed a top-down approach in master planning the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental bottom lines that focus on planning as a tool to improve the health and well-being of people while maintaining sustainability standards. Sustainable development was added as one of the main goals of all planning endeavors in the late 20th century when the detrimental economic and the environmental impacts of the previous models of planning had become apparent. Similarly, in the early 21st century, Jane Jacobs's writings on legal and political perspectives to emphasize the interests of residents, businesses and communities effectively influenced urban planners to take into broader consideration of resident experiences and needs while planning.
