Big Data, KDD and Citizen Participation to Ensure Coexistence between Economic Activity and Citizens’ Quality of Life

The project embodies a new way of making urban planning. Fueled by massive information (open data and big data) and complemented with qualitative data arising from citizen participation, the project applies novel methodologies of spatial analysis based on machine learning and artificial intelligence to inform, simulate, and draft a public policy that puts the focus on preserving liveability in cities.

The use of technology has radically transformed an existing type of master plan which regulates public establishments, food shops, and tourist services in the central district of Barcelona. The area has a dense and vulnerable population living within a fragile urban morphology. At the same time, it has a high rate of economic activities—specializing in leisure—that generates negative impacts on the life quality of residents such as noise, cleanliness, people in public space, and increment of logistics.

Given the complexity of the urban context, the project has undergone 4 phases, each of them generating its own outcome: research (data driven diagnosis), co-creation (citizen participation), proposal (simulation tool), and approval (regulatory framework).

The research phase started in October 2016 with the drafting of four preliminary studies prior to the kick-off of the drafting process (April 2017) related to the description of the urban fabric (data atlas), the impact of nocturnal activities on health, and the tourist trends and their impact on local commerce.

Specifically, the data atlas (consisting of more than 150 cartographies of the district) provides a solid structure to justify the *Plan*’s main objective—to preserve the quality of life in cities—thanks to the use of cutting-edge technologies (sensitization, machine learning, artificial intelligence) and European transparency laws that have made available relevant information about public management, urban services, and citizens’ behavior.

The data atlas not only illustrates and measures for the first time the physical and sociodemographic characteristics of the urban fabric, the type and saturation of economic activities, and the paths of citizens and visitors in the neighborhood but also describes the urban impacts on the health of inhabitants (caused by noise, pollution, or residential vulnerability).

The co-creation phase, driven by technicians and the previous diagnosis, has forged a large consensus thanks to a participatory process (local entities, retailers, and neighbors worked together in workshops, public events, interviews with selected actors, and online participation through the City Council digital democracy platform, and the political implication of the City Council, that co-authored the plan.

From the citizens’ perspective, they were involved in a massive data collection process, empowering them to build data sovereignty structures and participate in decision-making at a local level. On the public bodies side, the project proposes a system both to inform and evaluate urban planning and policies at a European level, supplying a common ground of knowledge that can be exchanged and compared between cities.

In parallel to the participation process, the proposal phase was based on a predictive model of economic activities aimed at measuring and anticipating different urban impacts like noise, police complaints, and social vulnerability, that led us develop a master plan with a strong parametric and dynamic component. Prior to the final approval, we created a software to simulate different scenarios according to the regulatory parameters and set the limit value in accordance to the plan objectives.

The plan was initially approved in September 2017, following a period of public information that led, after incorporating the feedback from different actors, to the final approval in February 2018. Today, the plan has been in force for almost a year. The city council is applying the master plan by means of a software, based on the regulatory parameters, that ensures transparency and makes the process of opening a business easier, faster, and trustable.

As a result of this two-year process, the project emphasizes the role of urban planning as an instrument to put the city as a common good over the free market. It proposes an innovative contribution by means of a real case study to European urban planning discipline and public policies framework regarding the regulation of economic activity under the Services Directive. In a growing urban world, we must ensure that European cities are able to guarantee the right to the city, i.e., citizens’ rights to health, work, shelter, and leisure but also that urban environments allow citizens to reach a full life in harmony with economic activity.

300.000 Km/s (ES) is an urban innovation office based in Barcelona that explores the potentials of data and new computation paradigms to extract relevant information with the aim to improve urban planning and decision-making. Directed by Mar Santamaria Varas and Pablo Martinez Diez, our interdisciplinary team works in the fields of urban analysis, cartography, strategic planning, development of digital tools, and digital humanities. In the last five years, we have collaborated with public entities, international firms, cultural and scientific institutions and non-profit organizations. 

Our projects have been recognized with various awards and mentions—among others BBVA-Civio Data Visualisation Award (2014), Open Data Institute Awards (2016), CityVis Prize (2017), Biennial Española de Urbanismo y Arquitectura (2018), and LLuís Carulla Award (2018)—and have been exhibited at the Biennale of Venice, the Chicago Arts Institute, the Center of Contemporary Culture of Barcelona, and Madrid CentroCentro, among others.
