The data itself has no value, the value derives from its use or, more specifically, when through its processing we are able to create information that supports decision making
True urban intelligence will only happen when those who govern the territory are able to establish strategies that lead to the construction of the city as a platform, creating the necessary and sufficient conditions to, taking advantage of information management and data science leveraged in big data, radically change the paradigm of planning and management of our cities and towns.
But the data itself has no value, the value stems from its use or, more specifically, when through its processing we are able to create information that supports decision making and leads to action (information is given in context).
In this sense, on this page, you can consult some of the data analytics and visualization solutions supported in big data that are still under development for the various partners of NOVA Cidade – Urban Analytics Lab and that are open to contributions and participation of interested researchers.

Monitoring environmental justice in the city of Lisbon
Description
Environmental injustice is the disparate treatment of vulnerable populations regarding access to environmental amenities, such as green spaces and quality infrastructure, and exposure to pollutants. In Portugal, environmental justice is not yet being monitored, which means that vulnerable populations, with less economic and political power, are more sensitive to situations of injustice. The creation of an environmental justice indicator for Lisbon would not only allow the visualization of the current environmental situation and demographic vulnerability, but also inform future administrative decisions to improve the quality of life of vulnerable populations.
Expected results
Create a tool that allows monitoring of environmental justice in the city of Lisbon, intersecting Census data with environmental indicators for the city.

Spatial behaviour of urban tourists
Context/Description
There is little knowledge available on the spatial behaviour of urban tourists, and yet tourists generate an enormous quantity of data when they visit cities. Public Wi-Fi networks can be used to track their presence through their activities and analyze their behaviours. The city of Lisbon is the capital of Portugal, having an area of approximately 100 Km2, and 500 000 inhabitants. Accordingly, with the tourism statistics provided by the Statistic Portugal, visited the Lisbon Metropolitan Area about 5 483 600 tourists during 2018. So it becomes essential to understand tourists behaviour to Lisbon city managers develop strategies to provide better services to tourists that visit Lisbon.
Research questions
• What are the demographic characteristics of the tourists that use the public Wi-Fi network in Lisbon?
• How is the spatial and temporal profile of the tourist’s Wi-Fi connections during weekdays and during the day?
• What are the POIs in the surroundings of the Wi-Fi access points?
• What are the demographic characteristics of tourists that visit a certain city area and at what time?
Outcome
Cluster and profiling Wi-Fi spots considering tourists demography, Wi-Fi connections, and the POIs in the surroundings of the Wi-Fi access points
Data sources
• Public Wi-Fi network data: The data used corresponds to a sample of 20%, collected in Lisbon between 1 March 2018 to 31 May 2018, and contains information about the device used to make the connection to the network, lead, access point, spot, user gender and age.

Identification of waste deposited outside of containers
Description
Waste collection in the city implicates a complex and extensive operation, where the correct deposit of waste in the adequate containers is an important success factor. Regardless of a set of awareness campaigns in that direction, there are still problems related to the wrongful disposal of waste outside of the disposal equipment destined to that end (recycling bins, etc.) which imposes an additional effort of the teams that carry out the collection. It would be of great added value to the Direção Municipal de Higiene Urbana (Department of Municipal Urban Hygiene) if their teams could access near real-time information about the places where there were undue deposits and the volume of waste, as well as planning if there was an identification of problematic spots, based on their history.
Expected results
The challege has the goal to resort to image and/or video recognition technology to get one or more of the following points about solid waste disposal outside of the usual deposit locations:
- classification of the type of waste (great volume, undifferentiated waste)
- waste volume

Identification of waste deposited outside of containers
Description
Mobility is seen as one of the greatest challenges that cities must face today. Recently, the use of soft modes of mobility, such as the use of bicycles and electric scooters, in the commuting movements of the population, has had significant growing adoption in the city of Lisbon. Moreover, as the amount of available information and the pressure to enforce sustainable and safe policies increases, stakeholders and policy makers require faster and more targeted actions. As such, the need to provide decision support systems to municipal authorities is greater than ever. Understanding and quantifying the past and current state of mobility is crucial for this purpose. As such, we proposed to use data from bicycle lane counter sensors, through EMEL’s open data portal. The goal is to elaborate a structured data collection and deeper knowledge in terms of contextual variables, and to develop relevant models which can allow the recognition of commuting patterns, from soft mobility modes, in the city of Lisbon.
Objective
More specifically, the objectives of this challenge are as follows:
- Develop a structured data collection, including data regarding EMEL’s bicycle meters, and relevant contextual data;
- Develop a prescriptive model, capable of identifying commuting patterns, in the city of Lisbon, from soft mobility modes;
- Create descriptive dashboards, in real time, fed with the model’s results;
- Support the implementation of this model in the intelligence services of the Municipality of Lisbon;
- Publish an article about the work developed;
- Other original ideas using the available data are also welcome.
Fix my street biased city governance
Description: Today one of the best practices in the participatory governance of cities taking advantage of collective intelligence, the applications of the “Fix my street” type allow to identify in real time and through direct communication of citizens using their smart phones the problems of cities and promote their resolution as quickly and efficiently as possible. However, the generalization of their use has raised the question of the digital divide and the doubt about their capacity to respond to the needs of the city and ensure one of the ambitions of SDG 11 – Sustainable Cities and Communities, inclusion, that is, the way of managing the city guarantees the quality and the level of service to all citizens and is not biased by the degree of digital literacy of the different socio-economic realities of the urban fabric of the city. In this project we intend to cross-check the data collected by “fix my street” applications with socio-demographic data to better understand the phenomenon.

Analytical model based on data from environmental sensors in Lisboa
Context / Description
Big Data is increasingly used to help meet the goals of climate health, environmental sustainability and resilience in countries and cities worldwide. The data used in this process is generated from sensors that keep track of environmental variables such as CO2, NO2, O3, etc., and measure their levels in the atmosphere. This information can be used in the development of analytical and machine learning models that make it possible to describe, predict and prescribe the environment status in a current moment and its evolution, access the level of air pollution and, associate it with the communities’ behaviours regarding, for example, traffic and industrial production.
This challenge aims at developing these sorts of analytics in the context of the city of Lisbon, under the scope of the “Dados ao Serviço de Lisboa” project, that joins the Municipality of Lisbon with the Universities ISEL and NOVA IMS – the students developing their thesis on this challenge will receive advisory from both universities.
Goals
More specifically, the goals of these challenges are the following:
- Build a “smart environment” analytical model that can describe environmental health and air quality patterns in the city of Lisbon;
- This model should also be able to determine the biggest contributors to atmospheric deterioration; cluster and profile the places in the city based on air quality variables, inform about the location characteristics and demographic attributes of the population in the different clusters; predict air quality and build if-then scenarios based on changes in the attributes of the people’s and place’s profiles;
- Build real-time descriptive Dashboards fed with the model’s output;
- Implement this model in the Lisbon Municipality intelligence services;
- Publish a paper on the subject matter.
Creation of a general traffic indicator and indicators for each of the main entry roads into the city
Description
The characterization of traffic in the municipality, using a single global indicator, is undoubtedly a determining factor for the correlation with other areas, both in management and administration. In addition to the characterization of traffic in the city, it is important to know the status of the main points of entry of Lisbon and the main roads within the city (in addition to establishing the basis for the allocation of the global indicator, they allow an assessment of the state of traffic on the outskirts of the municipality, with implications for the behavior of roads managed by other road operators, and which the municipality does not directly control). Thus, in addition to introducing a holistic component in the global perception of the city, it will be possible to contribute to the promotion of sustainable mobility (correlating with global indicators of other means of transport in the long term).
Expected results
The challenge aims to:
- build a single global indicator to characterize the state of traffic in the municipality in real time, as well as indicators for the main roads of the city ( N10, A1, A12, A30, A5, N6 (Av.

Design of a methodology for real estate price forecasting taking advantage of the geospatial dimension
Context / Description
Econometric models for real estate price forecasting have been used for a long time, resorting to OLS methods, and making functions autonomous for specific geographic levels, by county or groups of councils. These models ignore the relationship between the value of the real estate and that of those who they circle geographically. Likewise, they do not take advantage of the possibility of using data from real estate transactions in the geographic vicinity, carried out in the past. The recent advances in Geographic Systems Information (GIS) and the technologies they entail has opened the door to the micro-location of real estate and, with it, the production of statistics not subject to an administrative division. This way, the main objective of the process to be developed is the design of a methodology for real estate price forecasting that takes advantage of econometric models together with the geospatial dimension.
Data sources
The data sets for the challenge will be presented in-depth by the start of the challenge. In summary, they comprise information for each asset sold, such as the sale price, number of rooms, area, postal code, etc. The datasets have a history of data since 2007. They cover mainland Portugal but focus on the main cities and metropolitan areas, where the market has more expression.
Goals
The goals of this challenge are the following:
- Analyse the historical evolution of real estate price in Portugal over the last 15 years, concerning their location and configuration;
- Development of an econometric framework for real estate price estimation (forecasting), resorting to state-of-the-art approaches found in the related literature;
- Geographically locate each property and its surrounding properties using GIS technologies, to understand the extent to which there is a correlation between sale prices of neighbour assets;
- Incorporate this data in the price estimation model to improve its prediction accuracy and analyse the outcomes and their quality;
- Introduce the new real estate price forecasting model into production, by making it available for third party agents to make predictions regarding the properties they have under analysis.
Business Intelligence Tool for Analyzing the Sustainability of Urban Food Systems
To face challenges such as food waste, the need to adapt to climate change and the contrasting double childhood obesity/hunger, it is necessary to rethink food systems according to a holistic, systemic and integrated vision, supported by circularity strategies, aiming at sustainability, in its social-environmental-economic whole.
Within the scope of the Living Lab of Hub Criativo do Beato, its potential contribution to the sustainability of the Food System in the city of Lisbon will be evaluated, with the participation of the different actors in the food value chain on site and in neighboring parishes, promoting the circular economy in the food chain, namely through strategies to focus on local production, short circuits, and strategies for closing nutrient cycles.
To support the analysis of the sustainability of the chain, it is intended to develop a tool that allows capturing data on the food that is consumed in the Hub, agnostic in relation to the different stock and sales management systems, and that provides information on different aspects related to the sustainability of the HCB food system (namely distance of supply, food typology, production methods, destination). The tool will receive and process the input (food products) and output (produced food waste) data from the food and associate it with environmental analysis elements (from existing databases), joining the processed data in a centralized data repository. This repository will serve as the basis for the development of analytical applications to analyze the sustainability of urban food systems.
