DataCités 2: data use and sharing strategies
DataCités 2 est une exploration portée par le Lab OuiShare x Chronos qui propose une méthodologie d’accompagnement des collectivités pour la conception de data services urbains afin de développer leur capacité d’agir dans le domaine de la data, notamment en ce qui concerne la donnée partagée.
 
Pour cela, la démarche conjugue :
 
- Un accompagnement personnalisé de chaque territoire partenaire : République et canton de Genève, Ville d’Antony, Communauté de communes du Bassin de Pompey, Communauté urbaine Grand Poitiers, Communauté d’Agglomération de la Rochelle.
 ...
DataCités 2 is an exploration carried out by the OuiShare x Chronos Lab which offers a methodology to support communities in the design of urban data services to develop their capacity to act in the field of data, especially in terms of shared data.
 
To do this, the approach combines:
 
- Personalised support for each partner region: Republic and Canton of Geneva, City of Antony, Community of Municipalities of the Pompey Basin, Greater Poitiers Urban Community, Community of La Rochelle Urban Area.
 
- Inter-regional workshops: to share the ambitions and usage cases in the regions, their problems and levers to action with public and private partners, associations, experts, etc of DataCités 2. These workshops promote the sharing of knowledge, experiences and the creation of a community of partners.
 
- Capitalisation on an ongoing basis: using a logbook in which we record all the ideas shared by the members of DataCités 2, the projects of each region, lines of thought, resources, etc.
The spatial and energy impact of data centres on regions
Le projet de recherche ENERNUM donne une image du paysage des data centers en France et dans trois territoires des États-Unis, représentant chacun des situations spatiales et énergétiques différentes (ville dense, espace périphérique, rural). Facteur potentiel de déséquilibre des systèmes énergétiques locaux, objets dont l'accumulation urbaine et la dispersion rurale questionnent, les data centers font ici l'objet d'une analyse approfondie pour mieux appréhender les nouveaux territoires numériques en construction, les solidarités énergétiques à construire et les alliances d'acteurs à mettre en place.

The ENERNUM research project gives an image of the data centre landscape in France and three regions of the United States, each representing different spatial and energy situations (dense city, peripheral space, rural). A potential factor in the imbalance of local energy systems, objects which urban accumulation and rural dispersion bring into question, data centres are the subject of an in-depth analysis to better understand the new digital regions under construction, energy solidarity to create and stakeholder alliances to be put in place.

The report addresses three issues:

- energy conservation and the use of renewable energies;
- integration of data centres into local systems through mutualisation, exchange, connections and less infrastructure redundancy;
- architecture and spatial integration of infrastructure within cities and regions.
 
The research offers up elements to understand, get to grips with and decode both the data centre object, as well as its interactions with the environments into which it fits in its architectural and urban dimensions, in relation to energy, economic and governance issues.

Actes de Mobilités et (r)évolutions numériques
L’observation des usages et des pratiques est rendue possible par la collecte de données de façon massive. Les apports et potentiels des technologies numériques et leurs capacités à changer les lignes de la mobilité interrogent les chercheurs en sciences humaines et sociales. La revue Netcom y consacre un numéro spécial. Celui-ci illustre une partie des communications présentées lors du 15 e colloque du groupe Mobilités Spatiales, Fluidité Sociale (MSFS) de l’Association Internationale des Sociologues en Langue Française (AISLF). Intitulé « Mobilités et (r)évolutions...
Observation of use and practice is made possible by big data collection. The contribution and potential of digital technologies and their ability to change the lines of mobility are questioning researchers in the humanities and social sciences. Netcom magazine is devoting a special issue to it.
It contains some of the papers presented at the 15th symposium of the Spatial Mobility, Social Fluidity (SMSF) group of the International Association of Sociologists in the French Language (IASFL). Entitled "Mobility and digital (r)evolutions", the symposium took place on 8 and 9 November 2016 in Marne-la-Vallée and was held under the aegis of Labex Futurs Urbains, the Ile-de-France Region and Ifsttar. While the term "mobility" was understood in a broad sense as referring to the renewal of recent conceptual and empirical approaches to mobility in the social sciences, the collected articles are more specifically concerned with travel, both from the point of view of individual practices and the transport systems on which they are taken.

A total of 9 articles are presented in this issue and explore three lines of thought. They aim to question the innovative (or not) potential and inputs of digital technologies. The first focuses on the potential and limitations of new digital data for mobility analysis. The second and third axes consider how travel practices are transformed by digital technology. However, while the second axis targets new mobility offerings, the third is more focused on a set of practices.
 
An integrated, multi-criteria approach to decision-support tools: contextual elements for regional data management
La compréhension et le traitement des enjeux environnementaux, sociaux et économiques à l’échelle territoriale nécessitent des approches transversales, et pour cela des outils d’aide à la décision et à l’action publique, en faveur de politiques publiques plus intégrées, notamment pour la planification territoriale et urbaine. En parallèle, on assiste à un élargissement exponentiel des possibilités offertes par le numérique ainsi qu’à de nouvelles opportunités en matière de données mobilisables et de moyens de les traiter et de les valoriser via des outils pour la création de connaissance dans une logique d’aide à la décision.
...
Understanding and addressing environmental, social and economic issues at the regional level requires transverse approaches, and for this, tools to assist in decision-making and public action, in favour of more integrated public policies including regional and urban planning.
At the same time, we are witnessing an exponential expansion of the possibilities offered by digital technology as well as new opportunities in terms of mobilisable data and ways to process and realise their full value through tools for creating knowledge within a decision-support logic.
The study is based on in-depth analysis of observational and regional modelling tools, as well as an analysis of the life cycle of the data and its technical, legal and economic environment, to offer a grid and success factors for tool design, and opportunities for thinking about the management and exploitation of regional data.
Accra Mobile - participatory mapping of small-scale transport
A Accra, 80% des déplacements motorisés sont assurés par les Trô-Trô. Ces véhicules - des minibus de 10 à 19 passagers - sont exploités par des opérateurs privés qui s'organisent le long de lignes. En 2015, le gouvernement Ghanéen a créé les DoTs (Departement of Transports) au sein de quatre municipalités d'Accra. Ces organismes - notamment en charge de la régulation des taxis et des Trô-Trô au sein de la capitale Ghanéenne - ont procédé à un appel à projet pour cartographier le transport artisanal et ainsi développer les outils nécessaires à l'analyse du fonctionnement du réseau de Trô-Trô. L'objectif second était de développer une...
In Accra, 80% of motorised trips are provided by the Trô-Trô. These vehicles - minibuses for 10 to 19 passengers - are run by private operators who organise their service along routes. In 2015, the Ghanaian government created DoTs (Transport Departments) in four Accra municipalities. These bodies - notably in charge of the regulation of taxis and Trô-Trô in the Ghanaian capital - have issued a call for projects to map small-scale transport and thus develop the tools necessary to analyse the functioning of the Trô-Trô network. The second objective was to develop an innovative approach around digital common places - via the use of OpenSreetMap tools - in order to simplify the process of data collection, processing and formatting.
 
The project was divided into three phases:
 
Phase 1 - line identification
Concordia University students identified the 300 lines that make up Accra's transportation system and then, on a sample of 60 lines, conducted studies on the frequency of line departures.
 
Phase 2 - data collection
The Transitec design office, with the help of the Jungle Bus team, worked to formalise an automated data collection and processing protocol, before formatting the data describing the Trô-Trô transport offer.
 
Phase 3 - data processing and publication
Following the identification of lines during phases 1 and 2 of the project, Ghanaian OpenStreetMap contributors began recording the location of stops and GPS tracks of the Trô-Trô lines directly on OpenStreetMap using OSM Tracker.
 
Data quality was monitored throughout the collection process by the Jungle Bus team. An OSM validation tool (Jungle Bus ruleset) was created for this purpose, allowing the plug-in to send alerts to collection supervisors when an error or omission is spotted. The OSM2GTFS tool finally created a GTFS dataset from GPRS routes extracted from OSM and a schematic map of Accra's Trô-Trô network was created.
OPAL - big data supporting development
Depuis quelques années, le monde vit une « révolution des données ». L’utilisation du téléphone, de réseaux sociaux, de paiements électroniques, dans nos activités personnelles et sociales crée de plus en plus de données qui sont de plus en plus précises (“big data“). Celles-ci sont en majorité produites, stockées et exploitées par des entreprises privées : opérateurs télécoms, banques, plateformes web et réseaux sociaux, etc. Or, en matière notamment de santé, d'éducation, d'agriculture ou de transport par exemple, les opportunités sont considérables pour mieux diagnostiquer grâce à ces données les besoins des populations et des...
In recent years, the world has been experiencing a "data revolution." The use of telephones, social networks and electronic payments in our personal and social activities creates more and more data that is more and more accurate ("big data"). Most of this data is produced, stored and operated by private companies: telecom operators, banks, web platforms and social networks, etc. However, in the areas of health, education, agriculture and transport, for example, there are considerable opportunities to better diagnose the needs of populations and regions through this data. Can big data be used ethically and securely to produce information for the public interest and sustainable development goals (SDGs)? This challenge is the ambition of the OPAL project (for "Open algorithms").
 
Launched in December 2016, the project is being developed by a consortium of public, private and academic partners around the Data-Pop Alliance think tank, MIT Media Lab, Orange, Imperial College London and the World Economic Forum.
 
AFD's funding of 1.5 million euros means an initial version of the solution has begun to be deployed, as well as pilot operations in Colombia and Senegal, in partnership with national statistics agencies and two major telecoms operators (Sonatel in Senegal and Telefónica in Colombia). This funding provides a boost to a project already supported by the World Bank and the Global Partnership for Sustainable Development Data (GPSDD).
 
« Villes, numérique et innovation sociale : expériences françaises »

En pleine actualité liée aux enjeux de solidarité et d’accès aux services publics, cette publication questionne l’emploi des infrastructures et des usages numériques pour développer les cas d’usages en ville, dans la manière de nous déplacer, de consommer, d’interagir. Elle s’inscrit dans un contexte plus global d’urbanisation croissante et de densité démographique, interrogeant les enjeux de développement durable et de la qualité de l’air, de la mutation des transports et de la mobilité, la préservation des services publics et de l’accès aux soins ou encore la promotion du vivre-ensemble.

Une quinzaine de fiches, chacune dédiée à...

Over recent years, we have witnessed the constant growth of urban density all around the world: according to the United Nations (UN), around 70% of the world’s population will live in cities by 2050. This global phenomenon is associated with numerous challenges, such as sustainable development and air quality, the transformation of transport and mobility, the preservation of public services, access to health care and the promotion of living better together.
 
In this publication, France urbaine, an association bringing together major cities, inter-municipalities and metropolises across France, wanted to draw up a panorama of the initiatives implemented by urban centres to make living better together of the city. In keeping with the topical issues of solidarity and access to public services, this publication examines the possible existence of a specific French model of the smart city.
Smartseille, the eco-neighbourhood of the future to live in the present
La Ville de Marseille et l’établissement public Euroméditerranée réalisent dans les quartiers nord de la ville la plus grande opération de rénovation urbaine d’Europe du Sud. C’est dans ce cadre que "smartseille", le projet d’écoquartier conçu par Eiffage, a vu le jour : 58 000 m2 ont été construits sur 2,7 ha en associant harmonieusement logements, bureaux et services tout en offrant des logements et des bureaux à des prix accessibles et un accès aisé à toutes les nouvelles technologies.

Cet écoquartier du XXIe siècle apporte aussi à ses habitants comme à ses usagers le meilleur du développement durable :...
The City of Marseille and the Euroméditerranée public institution are carrying out the largest urban renewal operation in Southern Europe in the northern districts of the city. It is within this context that "smartseille", the eco-neighbourhood project designed by Eiffage, was born: 58,000 m2 were built on 2.7 hectares by harmoniously combining housing, offices and services while offering housing and offices at affordable prices and easy access to all new technologies.

This 21st century eco-neighbourhood also provides its inhabitants and users with the best sustainable development: supply of renewable energy, eco-design of buildings adapted to the Mediterranean environment, a mix of functions, urban agriculture.

With great technical ambition and with the help of Orange Business Services, smartseille promotes urban digital transformation and responds to new lifestyles and ways of working. Technology is not an end in itself but a means to make accessible innovative services that simplify the lives of residents, promote the development of social ties and encourage the sharing of resources: e-concierge, dynamic signage, interactive terminals, shared car parks. A web and mobile portal serves as a platform for interaction between residents.
Recyclean®: an exclusive process for reusing polluted roads
L’économie circulaire est déterminante pour l’avenir du BTP car elle contribue à préserver les ressources et à mieux gérer les déchets. Elle s’inscrit pleinement dans la transition écologique et l’innovation, deux des piliers du plan stratégique d’Eiffage.
 
Ainsi Eiffage Route a mis au point Recyclean®, un procédé exclusif de réemploi des chaussées polluées, notamment par des hydrocarbures aromatiques polycycliques (HAP) qui s’inscrit pleinement dans cette stratégie. Recyclean® permet de régénérer ce type de chaussées et de retraiter les matériaux existants. Cette solution ne génère pas de déchets, ni de...
The circular economy is crucial for the future of construction because it helps preserve resources and better manage waste. It is fully in line with the ecological transition and innovation, two of the pillars of Eiffage's strategic plan.
 
So Eiffage Route has developed Recyclean®, an exclusive process for reusing polluted roadways, including polycyclic aromatic hydrocarbons (PAHs), which is fully part of this strategy. Recyclean® allows this type of roadway to be regenerated and existing materials to be reprocessed. This solution generates no waste or landfill costs for polluted materials and fully meets the Energy Transition for Green Growth Act (LTECV) of 2015, which aims, among other things, to reduce the amount of waste admitted in storage facilities by 30% by 2020 compared to 2010, and 50% by 2025.
 
Ecologically and socially virtuous, the Recyclean® process avoids using new materials on construction sites as well as movements of trucks loaded with polluted materials. Recyclean® is also more economical because it avoids both the transport and the systematic landfilling of these materials.
