WHAT IS RATIONALIZATION?
A DISCLAIMER: Urban planning is an attempt to rationalize our environment, which should not be mistaken with the rationalization of the occupation itself.
Planning is considered a 'wicked problem' (criteria displayed below). As a result, much of the planning profession requires working with new information and solving unstructured problems. Levy and Murnane (2013) name these two characteristics as broad categories of work that cannot be fully rationalized or replaced by technology. Despite this, strides within planning have been made towards and away from rationality.

ACCREDITATION IN URBAN PLANNING
The American Planning Association
The First National Conference on City Planning led to the creation of The American Institute of Planners in 1917, which later became the American Planning Association (APA). The association boasts more than 40,000 members and is a crucial hub for the accreditation of planning figures and theories, with the American Institute of Certified Planners (AICP) and the Journal of the American Planning Association (JAPA) falling under its expansive umbrella. The AICP provides experienced professional planners with national accreditation. Similarly, the JAPA provides accreditation to planning theories and works, publishing a quarterly journal, since 1935.
Urban Planning Education
The world's first higher education program in urban planning opened in 1909, at Liverpool University. America's first opened in 1923, with Harvard University's program for city and regional planning. In the 1960s and 70s, the profession saw significant growth; this was reciprocated by universities. The Planning Accreditation Board (PAB), founded in 1984, currently “accredits 78 master’s and 16 bachelor’s programs at 80 North American universities” (PAB). A master’s degree in planning opens up job opportunities in every aspect of planning, including design, consulting, government, and even jobs with an economic focus.
Predictability: Accreditation of universities ensures that students can guarantee a quality planning education, and that their degree correctly certifies their abilities. As planning education improves, a planner’s skillset becomes increasingly standardized and predictable. However, planners today also deal with an array of outside factors that influence their progress, some of which act as irrationalities. Three crucial outside factors to a planner’s function are government and regulation, community input, and technology.
GOVERNMENT, ZONING, AND CONTROL
Zoning refers to government regulation on the type of structures that can be built in a certain area. Cities enact zoning policies, with the help of planners, to achieve a more predictable outlook. Zoning regulations can provide a conflict for planners, between what is required and what is optimal.
In Apex, NC, for example, the 2045 Land Use Map (below) requires a significant amount of housing that is medium density, which can include single family homes. However, current trends in the profession point towards sustainable urban planning, which includes housing density.
Control: Rationally, a professional with the highest level of academic accreditation for the topic at hand, amongst all involved actors, should receive the plurality (if not majority) of control. In the case of a planner with a master’s degree, much of their planning control is lost to government regulation.
ADVOCACY PLANNING, CONTROL, EFFICIENCY
Efficiency and control: Robert Moses’s impact is generally viewed negatively, in the current world of planning. His projects displaced many lower class New Yorkers. I believe, however, that this form of the planning profession is far more rationalized than what exists today, on account of efficiency and control. Moses actualized a massive portfolio of projects with a speed that has never been replicated in urban planning since.
Jacobs organized community members to rally against Moses. She could not always defeat him, but her ideals far outlasted his. Current American planning implementation incorporates public opinion. The majority of projects must be granted approval by the town or city council, a body that meets only once a month and can discuss projects over the course of multiple meetings. The meetings allow time for council members and constituents to voice their opinions on proposed projects.
Efficiency and control: The forums for public opinion that planners must attend, as well as the extensive process through which proposals are put (see below), decrease the rationality of the planning profession, via the principles of efficiency and control. Time that planners spend gathering public opinion is time that could be used to practice the expertise that is gained through a planner’s accreditation.
TECHNOLOGY, EFFICIENCY, AND CALCULABILITY
Innovations in planning technology
Geographic information science (GIS): GIS combines the important planning responsibilities of spatial mapping and data. Using updated imagery from satellites, GIS technology gathers data and visualizes it for planners.
Virtual Reality (VR): Some VR platforms allow planners to virtually create realistic renderings of projects that can be manipulated and viewed from all angles. Other forms of urban design technology are less complicated and more user friendly. Planners can save the time and energy that is required to build a physical model of proposed projects, by doing so virtually.
Smart cites: Smart cities are defined by devices that are connected to the 'Internet of Things.' They upload and store data that can be used by planners. An example would be a road or sidewalk sensor that monitors vehicle or pedestrian traffic. When connected to the Internet of Things, this sensor could communicate with stop lights to better regulate the flow of traffic
Efficiency and calculability: Technology brings efficiency to urban planners by reducing the cognitive and manual routine tasks that are associated with gathering data and displaying proposals. New methods of data collection (smart cities), increase the calculability within a planners job, by providing accurate and up-to-date information.
MY TAKEAWAYS
Through the research described on this page, I’ve learned that rationalization within the urban planning profession is not a linear or simple process. Each of rationalization's four principles show up in varying combinations throughout the narrative of planning history. Efficiency is perhaps the most nuanced of the four, showing both growth and recession at different points in time.
The planning profession influences our daily lifestyles, and is therefore a communal topic. Evolving standards and values make a large mark on the changes in planning theory, which impact the way that the profession itself is conducted. Evolution is also the reason that planning has had a varying relationship with rationality. Much of planning is reactionary and has no true formula for complete rationalization.
