Tämän diplomityön tavoitteena oli kartoittaa haja-asutusalueen taksipalvelut ja kehittää maaseudun taksipalveluja niin, että taksit säilyisivät harvaanasutuilla alueilla myös tulevaisuudessa. Tavoitteet voidaan maaseututaksiliikenteen osalta tiivistää kahteen tavoitteeseen, joita painotetaan toimintaympäristön mukaan: taksiliikenteen markkinaosuudensäilyttäminen sekä maaseudun taksin palvelujen turvaaminen ja kehittäminen. Maaseutu on muutosten kourissa, väestö ikääntyy maaseudulla ja maaltamuutto kaupunkiseuduille lisääntyy. Maaseudun taksiliikenteen markkinat ovat myös muutosvaiheessa. Julkishallinnon säästöt ja liikennejärjestelmien kehittäminen pienentävät julkishallinnon korvaamien tavanomaisten taksimatkojen määrää, erityisesti haja-asutusalueella. Taksien työpäivää selvitettiin taksiyrittäjille tehdyssä kyselytutkimuksessa, tutkimuksessa korostui voimakkaasti viranomaisten, varsinkin kunnan merkitys taksiliikenteelle maaseudulla. Taksien perusliikenteeseen tulee yhdistää uusia palveluja. Luotaessa uusia ratkaisuja on tärkeää ottaa huomion yhteiskunnallinen, hallinnollinen ja lainsäädännöllinen ympäristö. Tähän liittyvät ongelmat ovat usein suurempia kuin muut ongelmatilanteet. Raportissa on toimenpidesuosituksia siitä, miten taksielinkeinoa tulisi kehittää. Eräs tärkeimmistä suosituksista on laaja, eri tahojen yhteistyö ja verkottuminen. Erittäin tärkeää on myös muistaa kouluttamisen ja markkinoinnin tärkeys.

La croissance de la population, de l'économie et des transports individuels motorisés, particulièrement depuis la seconde moitié du 20ème siècle, ont notamment comme corollaire le développement urbanistique hors des frontières de la ville-centre et la formation des agglomérations. Ces zones urbaines sont stratégiques puisqu'elles accueillent une part toujours plus importante de la population et représentent le moteur de l'économie nationale. Toutefois, le développement des agglomérations et de la mobilité individuelle motorisée ne va pas sans poser de nombreux problèmes, dont la résolution nécessite de les aborder à l'échelle de l'agglomération, en coordonnant les transports et l'urbanisation. Notre système politique fédéral se définit notamment par une répartition des compétences dans une multitude de domaines entre les trois niveaux institutionnels de la Confédération, des cantons et des communes. Cette réalité est particulièrement vraie en matière d'aménagement du territoire. Il est à noter que les plus petites unités institutionnelles (les communes) conservent encore aujourd'hui des prérogatives importantes dans ce domaine. Au début des années 2000, la Confédération a développé une politique publique en faveur de ces zones stratégiques. Au moyen du fonds d'infrastructure, la politique fédérale des agglomérations dans les domaines des transports et de l'urbanisation est une politique publique incitative. Le dépôt, par les agglomérations, d'un projet respectant un cahier des charges précis et proposant des mesures de coordination entre les transports et l'urbanisation, permet d'obtenir un cofinancement fédéral du transport d'agglomération. Parmi les projets d'agglomération de première génération présentés à la Confédération, certains ont obtenu le cofinancement, d'autres pas. Le dimensionnement trop généreux des surfaces à bâtir fut notamment un facteur d'échec du projet d'agglomération de Fribourg, alors que la capacité à développer l'urbanisation à l'intérieur de l'agglomération fut un facteur de succès du projet Lausanne-Morges. L'analyse des projets d'agglomération Riviera et Monthey-Aigle, qui sont des projets de deuxième génération, confrontée à des entretiens avec des urbanistes et des responsables politiques, permet d'identifier leurs faiblesses et leurs atouts. Le projet d'agglomération Riviera présente une complémentarité des territoires et un grand potentiel de développement, mais aussi un manque de cohésion des partenaires du projet. Quant au projet Monthey-Aigle, il existe une réelle volonté politique de trouver des solutions aux conflits, mais les possibilités de développer les transports publics sont faibles. Dans le cadre de l'examen fédéral de ces deux projets d'agglomération, les éléments précités pourraient être des facteurs d'échec ou de succès. La politique publique fédérale invite les agglomérations à penser le développement de leurs transports et de leur urbanisation à un niveau global. La prise de hauteur et la coordination politique que cela suppose sont à même d'améliorer le lieu de vie des trois-quarts de la population suisse et de préserver le moteur de l'économie nationale. The growth of population, economy and personal motorised transportation, most particularly since the second half of the 20th century, has, as a consequence, induced an expansion of urban areas outside the borders of cities and encouraged the formation of urban agglomerations. These urban zones are of strategic importance as they attract an increasingly large population and represent a real driver of the national economy. However, the development of these agglomerations and the motorised mobility of their inhabitants cause numerous problems which require solutions to be adopted at the level of the agglomeration involving the interconnection of transport and urbanisation. Our federal political system is characterised by a distribution of responsibilities in many domains among the three institutional levels, namely the Confederation, the cantons and the communes. This is particularly the case of territorial developments. It should be noted that the smallest institutional units, the communes, still hold today important responsibilities in this area. At the beginning of the years 2000, the Confederation has developed a public policy in favour of these strategic zones. Through the establishment of an infrastructure fund, the federal policy in favour of urban agglomerations in the areas of transport and urbanisation aims at providing incentives to agglomerations. The submission by the agglomeration of a project containing a clear description of tasks and measures to integrate transport and urbanisation can result in a cofinancing participation by the Confederation in this project. Among the projects of first generation which had been submitted to the Confederation, some have received the cofinancing, others have not. The too generous dimension of the building areas in the project submitted by the agglomeration of Fribourg was a factor of its failure, while the capacity to develop urbanisation within the agglomeration was a factor of success for the Lausanne-Morges project. The analysis of the projects of the agglomerations Riviera and Monthey-Aigle which are projects of the second generation, as well as the interviews of urbanists and concerned officials have allowed us to identify their strengths and weaknesses. The Riviera project provides a complementary approach and a high potential of territorial developments, but at the same time denotes a lack of cohesion among partners of the project. With respect to the project Monthey-Aigle, there is a real political willingness to resolve conflicts, but the potential for the development of public transports is small. In the consideration by the Confederation of these two projects, the factors mentioned above may bring success or failure. The federal public policy incites the agglomerations to conceive the development of their transportation and urbanisation plans at a global level. The elevation of interests and the political coordination that this requires can improve the place of living of ¾ of the Swiss population and preserve the engine of growth of the national economy.

Background and aim of the study: In Switzerland no HIV test is performed without the patient's consent based on a Voluntary Counseling and Testing policy (VCT). We hypothesized that a substantial proportion of patients going through an elective surgery falsely believed that an HIV test was performed on a routine basis and that the lack of transmission of result was interpreted as being HIV negative. Material and method: All patients with elective orthopedic surgery during 2007 were contacted by phone in 2008. A structured questionnaire assessed their belief about routine preoperative blood analysis (glycemia, coagulation capacity, HIV serology and cholesterol) as well as result awareness and interpretation. Variables included age and gender. Analysis were conducted using the software JMP 6.0.3. Results: 1123 patients were included. 130 (12%) were excluded (i.e. unreachable, unable to communicate on the phone, not operated). 993 completed the survey (89%). Median age was 51 (16-79). 50% were female. 376 (38%) patients thought they had an HIV test performed before surgery but none of them had one. 298 (79%) interpreted the absence of result as a negative HIV test. A predictive factor to believe an HIV test had been done was an age below 50 years old (45% vs 33% for 16-49 years old and 50-79 years old respectively, p <0.001). No difference was observed between genders. Conclusion: In Switzerland, nearly 40% of the patients falsely thought an HIV test had been performed on a routine basis before surgery and were erroneously reassured about their HIV status. These results should either improve the information given to the patient regarding preoperative exams, or motivate public health policy to consider HIV opt-out screening, as patients are already expecting it.

Eighty percent of the global 17 million deaths due to cardiovascular disease (CVD) occur in low and middle income countries (LMICs). The burden of CVD and other noncommunicable diseases (NCDs) is expected to markedly increase because of the global aging of the population and increasing exposure to detrimental lifestyle-related risk in LMICs. Interventions to reduce four main risks related to modifiable behaviors (tobacco use, unhealthy diet, low physical activity and excess alcohol consumption) are key elements for effective primary prevention of the four main NCDs (CVD, cancer, diabetes and chronic pulmonary disease). These behaviors are best improved through structural interventions (e.g., clean air policy, taxes on cigarettes, new recipes for processed foods with reduced salt and fat, urban shaping to improve mobility, etc.). In addition, health systems in LMICs should be reoriented to deliver integrated cost-effective treatment to persons at high risk at the primary health care level. The full implementation of a small number of highly cost effective, affordable and scalable interventions ("best buys") is likely to be the necessary and sufficient ingredient for curbing NCDs in LMICs. NCDs are both a cause and a consequence of poverty. It is therefore important to frame NCD prevention and control within the broader context of social determinants and development agenda. The recent emphasis on NCDs at a number of health and economic forums (including the September 2011 High Level Meeting on NCDs at the United Nations) provides a new opportunity to move the NCD agenda forward in LMICs.

Background: Although the mechanisms are not well understood yet, evidence exists of the benefits of urban green spaces for human health. As a consequence, one of the concerns of public health interventions must be to promote the use of urban green spaces within cities. Aims: This study aims to explore the citizens’ purposes of use of urban green spaces as well as the elements related to the characteristics of these places that condition their use. Methods: In-depth interviews were conducted with non-hospitalised people living in different areas of Barcelona, with different socioeconomic status and different residential distance to urban green spaces (n = 20). Thematic content analysis of the qualitative data was performed. Results: Physical pursuits and attention restoration were identified as prominent purposes of use of urban green spaces. The natural features of urban green spaces were identified as the most relevant determiners for the use of these places. Conclusions: To promote the use of urban green spaces, qualitative findings from this study suggest that purpose-built places should be provided. Moreover, natural features of urban green spaces must be particularly taken into account when designing and maintaining them.

In the first part of this paper, we present the various academic debates and, where applicable, questions that remain open in the literature, particularly regarding the nature of trust, the distinction between trust and trustworthiness, its role in specific relationships and its relationship to control. We then propose a way of demarcating and operationalizing the concepts of trust and trustworthiness. In the second part, on the basis of the conceptual clarifications we present, we put forward a number of "anchor points" regarding how trust is apprehended in the public sector with regard to the various relations hips that can be studied. Schematically, we distinguish between two types of relations hips in the conceptual approach to trust: on one hand, the trust that citizens, or third parties, place in the State or in various public sector authorities or entities, and on the other hand, trust within the State or the public sector, between its various authorities, entities, and actors. While studies have traditionally focused on citizens' trust in their institutions, the findings, limitations and problems observed in public - sector coordination following the reforms associated with New Public Management have also elicited growing interest in the study of trust in the relationships between the various actors within the public sector. Both the theoretical debates we present and our propositions have been extracted and adapted from an empirical comparative study of coordination between various Swiss public - service organizations and their politico - administrative authority. Using the analysis model developed for this specific relationship, between various actors within the public service, and in the light of theoretical elements on which development of this model was based, we propose some avenues for further study - questions that remain open - regarding the consideration and understanding of citizens' trust in the public sector.

La présente recherche traite des défis posés à l'action publique territoriale par la transition énergétique, transition désormais érigée au rang de priorité par les autorités françaises et suisses, comme plus globalement européennes. Elle prend pour cela appui sur une analyse des démarches de planification énergétique territoriale menées entre 2007 et 2014 sur le territoire franco-valdo-genevois (agglomération du « Grand-Genève »). Considérées comme des laboratoires d'expérimentation de la territorialisation des politiques énergétiques, ces démarches sont ici examinées selon une perspective institutionnaliste et pragmatiste visant à mettre lumière les éléments qui interviennent dans la délimitation du champ des possibles en matière d'action publique énergétique et territoriale. Ce positionnement découle des évolutions observées sur le territoire franco-valdo-genevois durant la période d'étude (chapitre 1). Il découle plus précisément du constat de récurrence de certains points de blocage rencontrés aussi bien dans les démarches de planification énergétique elles-mêmes que dans les travaux méthodologiques qui ont pu être réalisés parallèlement à ces démarches, dans le but d'en affiner les outils techniques et organisationnels de mise en oeuvre. Ainsi, le point de départ de la présente recherche est le constat selon lequel on peine tout autant à construire des solutions énergétiques appropriables et réalisables par les acteurs des territoires concernés qu'à reconfigurer les outils de production de ces solutions. De ce constat découle l'intérêt porté aux cadres institutionnels qui régissent ces planifications énergétiques territoriales. Définis comme l'ensemble des repères - formels et informels - qui rendent possibles en même temps qu'ils contraignent les interactions territorialisées entre les acteurs, ces cadres institutionnels sont placés au coeur de la grille de (re)lecture des expériences de planification énergétique territoriale établie au chapitre 2 de la thèse. En référence aux concepts institutionnalistes et pragmatistes sur lesquels elle prend appui, cette grille conduit à appréhender ces expériences comme autant d'enquêtes contribuant, à travers le travail de mobilisation et construction de représentations territoriales auquel elles donnent lieu, à l'équipement sociocognitif d'un champ d'intervention territorial spécifique. Partant de l'hypothèse selon laquelle les potentialités comme les limites associées à l'équipement sociocognitif de ce champ orientent les possibilités d'action collective, la réflexion consiste en une application de cette grille à une trentaine d'expériences de planification énergétique territoriale. Cette application s'effectue en deux temps, correspondant à deux niveaux de lecture de ces démarches. Le premier porte sur les dispositifs organisationnels et les modalités d'interactions entre les cultures d'action qu'elles réunissent (chapitre 3). Le second se concentre davantage sur les supports cognitifs (représentations territoriales) autour desquels se structurent ces interactions (chapitre 4). Présentés dans le dernier chapitre de la thèse (chapitre 5), les enseignements tirés de ce travail de réexamen des démarches franco-valdo-genevoises de planification énergétique territoriale sont de deux ordres. Ils portent d'abord sur les caractéristiques des cadres institutionnels existants, la manière dont ils orientent ces démarches et délimitent les évolutions possibles dans les modes d'action collective et plus particulièrement d'action publique qui y sont associés. Mais ils portent aussi sur les potentiels de changement associés à ces démarches, et sur les pistes envisageables pour mieux valoriser es potentiels, dont l'activation passe par des évolutions profondes des systèmes institutionnels en place. -- In France as in Switzerland, local authorities stand out as leading players of energy transition, a transition that requires an important renewal of public intervention instruments. It is the stakes and the conditions of such a renewal that the present work aims to examine, based on the experiments of territorial energy planning led on the franco-valdo-genevan cross-border territory. Conceived as initiatives of relocation of the energy supply system, these energy planning initiatives are examined through an institutionalist and pragmatic « reading template ». This « reading template » consists of seeing these energy planning initiatives as pragmatist inquiries aiming, through a collective work of cognitive equipment of the territorial franco-valdo-genevan field of intervention, at the reconstruction of the means of coordination between people about their material, organizational and political territory. It opens towards a double reading of the energy planning initiatives. The first one concentrates on the organizational dimension of these inquiries - i.e. on the cultures of action which they gather and the modalities of interaction between them - whereas the second focuses on the cognitive substance which represents the medium of the interactions. This double reading provides insights at various levels. The first one concerns the (cognitive) territorial field of intervention that these energy-planning experiments contribute to draw. A field which, although better and better characterized in its technical dimensions, remains at the same time limited and " deformed " so that it values more the fossil energy systems, from which we want to release ourselves, than the renewable ones, which we would like to replace them with. The second level of teaching concerns the processes of production of territorial knowledge (PPTK) which presides over the demarcation and « equipment » of the territorial field of intervention. Examined through the institutional norms and the culture of action at stake in them, this PPTK turns out to create a sociocognitive "cross-border" area, the kind of area that could shelter the desired reconfigurations...on the condition that they are beforehand correctly "equipped", in cognitive and also in organizational terms. The determining factor for the quality of this equipment is concentrated in the third category of teaching. Starting with the opportunities created by these energy planning experiments concerning the renewal of public intervention instruments, these elements also allow us to take a new look at the urban area project under construction in this cross-border territory, a project th t shows itself closely linked to the energy experiments through a common challenge of territorialisation.

OBJECTIVE: Body mass index (BMI) may cluster in space among adults and be spatially dependent. Whether and how BMI clusters evolve over time in a population is currently unknown. We aimed to determine the spatial dependence of BMI and its 5-year evolution in a Swiss general adult urban population, taking into account the neighbourhood-level and individual-level characteristics. DESIGN: Cohort study. SETTING: Swiss general urban population. PARTICIPANTS: 6481 georeferenced individuals from the CoLaus cohort at baseline (age range 35-74 years, period=2003-2006) and 4460 at follow-up (period=2009-2012). OUTCOME MEASURES: Body weight and height were measured by trained healthcare professionals with participants standing without shoes in light indoor clothing. BMI was calculated as weight (kg) divided by height squared (m(2)). Participants were geocoded using their postal address (geographic coordinates of the place of residence). Getis-Ord Gi statistic was used to measure the spatial dependence of BMI values at baseline and its evolution at follow-up. RESULTS: BMI was not randomly distributed across the city. At baseline and at follow-up, significant clusters of high versus low BMIs were identified and remained stable during the two periods. These clusters were meaningfully attenuated after adjustment for neighbourhood-level income but not individual-level characteristics. Similar results were observed among participants who showed a significant weight gain. CONCLUSIONS: To the best of our knowledge, this is the first study to report longitudinal changes in BMI clusters in adults from a general population. Spatial clusters of high BMI persisted over a 5-year period and were mainly influenced by neighbourhood-level income.

Business actions do not take place in isolation. Complementary competencies and capabilities are the most important resources in the exponential knowledge growth. These resources are partially accessed via business partners. A company needs partners and the capability to cooperate, but also the awareness of the competitive tension, when operating in the market with multiple actors. The co-opetition research studies the occurrence and the forms of simultaneous cooperation and competition between companies or their units. Public sector’s governmental and municipal organs have been transformed into companies over the past years. Despite of their non-profit nature, public sector and public companies are adopting business doctrines from private sector towards efficient business operations. This case study aims to show, how co-opetition concept can be observed within public sector companies and in their operations with others, how public companies cooperate but also compete with others and why this happens. This thesis also explicates advantages and disadvantages of the co-opetition phenomenon.

The unusual mixed public-private structure of the urban bus market in the metropolitan area of Barcelona provides an interesting context in which to analyze the management challenges and opportunities of the partial privatization of public services. Initiatives used by the public regulator to promote competition for contracts, such as short term concessions to private contractors and the removal of entry barriers, have considerable potential for improving efficiency and quality. The growth in the share of routes managed by private firms in recent years shows that privatization is a credible threat that may well stimulate improved performance among public managers. The type of reform implemented in Barcelona is of interest to all metropolitan areas large enough to operate under constant returns to scale regimes, and suitable for potential concessions of routes in segregated areas inside the metropolitan area, so as not to miss out on the benefits of economies of density.

How do processes of power shape the urban environment in small Indian cities? On a day-to-day basis, who actually controls access to and the use of environmental resources? How is this done? Answering these questions contributes to our ability to develop a nuanced understanding the urban condition. In order to investigate these questions an actor-oriented approach is developed, drawing on the anthropological literatures on everyday governance and the everyday state. This conceptual framework informs an urban political ecology approach oriented towards everyday practices and the micro-politics of the (re)production of urban socio-natures. This thesis employs a mixed methods approach to qualitative research. Three cases are presented to explore: para (neighbourhood) clubs as governance actors, the governance of the urban pondscape, and the urban political ecology of solid waste management. These case studies serve to highlight how power shapes the (re)production of urban socio-natures through the everyday environmental governance practices of a complex network of governance actors. This work further demonstrates how multiple intersectionalities, including class, caste and access to political and social authority, shape these practices and their outcomes. Finally, the manner in which balances of power, place making and the formation of subject positions may both result from and shape everyday environmental governance practices and their outcomes is explored. This empirical investigation makes a number of contributions to the literature. It has explores the hereto-understudied topics of environmental governance in small cities in India, the urban political ecologies of non-piped water and of solid waste, and the role of clubs as governance actors. It further contributes to conversations within the literature on how to deepen and broaden Urban Political Ecology by engaging with everyday practices, and cases of ordinary, not-openly contested socio-natures. -- Comment les processus de pouvoir influencent-ils l'environnement urbain dans les petites villes indiennes ? Au quotidien, qui contrôle l'accès et l'utilisation des ressources environnementales ? Comment ce contrôle s'exerce-t-il ? Répondre à ces questions contribue au développement d'une compréhension nuancée de la condition urbaine. Afin d'explorer ces questions une approche actor-oriented de la gouvernance quotidienne est développée, faisant appel aux littératures anthropologiques de la gouvernance quotidienne et de l'everyday state. Ce cadre conceptuel établit ainsi une approche d'Urban Political Ecology orientée vers les pratiques quotidiennes et la micro- politique de la (re) production des socio-natures urbaines. Cette thèse emploie des méthodes qualitatives mixtes. Trois cas sont présentés afin d'étudier : les clubs para (quartier) comme acteurs de la gouvernance; la gouvernance de la pondscape urbaine; et l'urban political ecology de la gestion des déchets solides. Ces études de cas permettent de mettre en lumière la façon dont le pouvoir influence la (re)production des socio-natures urbaines par le biais des pratiques quotidiennes de gouvernance environnementale d'un réseau complexe d'acteurs. Ce travail démontre également comment plusieurs intersectionnalités, y compris la classe, la caste et l'accès au pouvoir politique et social, façonnent ces pratiques de gouvernance et leurs produits. Finalement, cette recherche explore la manière dont les équilibres de pouvoir, la fabrication de lieux et la formation de la position du sujet peuvent à la fois résulter de et contribuer à façonner les pratiques quotidiennes de gouvernance environnementale et leurs produits. Cette investigation empirique fait ainsi plusieurs contributions à la littérature. Elle explore les questions jusque-là sous-étudiées de la gouvernance environnementale dans les petites villes en Inde, de l'urban political ecology de l'eau non courante et des déchets solides, ainsi que du rôle des clubs comme acteurs de la gouvernance. Celle-ci contribue également à des débats sur la façon d'approfondir et d'élargir l'urban political ecology en travaillant sur les pratiques quotidiennes, et sur des cas de socio-natures ordinaires, pas ouvertement contestées.

Que ce soit d'un point de vue, urbanistique, social, ou encore de la gouvernance, l'évolution des villes est un défi majeur de nos sociétés contemporaines. En offrant la possibilité d'analyser des configurations spatiales et sociales existantes ou en tentant de simuler celles à venir, les systèmes d'information géographique sont devenus incontournables dans la gestion et dans la planification urbaine. En cinq ans la population de la ville de Lausanne est passée de 134'700 à 140'570 habitants, alors que les effectifs de l'école publique ont crû de 12'200 à 13'500 élèves. Cet accroissement démographique associé à un vaste processus d'harmonisation de la scolarité obligatoire en Suisse ont amené le Service des écoles à mettre en place et à développer en collaboration avec l'université de Lausanne des solutions SIG à même de répondre à différentes problématiques spatiales. Établies en 1989, les limites des établissements scolaires (bassins de recrutement) ont dû être redéfinies afin de les réadapter aux réalités d'un paysage urbain et politique en pleine mutation. Dans un contexte de mobilité et de durabilité, un système d'attribution de subventions pour les transports publics basé sur la distance domicile-école et sur l'âge des écoliers, a été conçu. La réalisation de ces projets a nécessité la construction de bases de données géographiques ainsi que l'élaboration de nouvelles méthodes d'analyses exposées dans ce travail. Cette thèse s'est ainsi faite selon une dialectique permanente entre recherches théoriques et nécessités pratiques. La première partie de ce travail porte sur l'analyse du réseau piéton de la ville. La morphologie du réseau est investiguée au travers d'approches multi-échelles du concept de centralité. La première conception, nommée sinuo-centralité ("straightness centrality"), stipule qu'être central c'est être relié aux autres en ligne droite. La deuxième, sans doute plus intuitive, est intitulée centricité ("closeness centrality") et exprime le fait qu'être central c'est être proche des autres (fig. 1, II). Les méthodes développées ont pour but d'évaluer la connectivité et la marchabilité du réseau, tout en suggérant de possibles améliorations (création de raccourcis piétons). Le troisième et dernier volet théorique expose et développe un algorithme de transport optimal régularisé. En minimisant la distance domicile-école et en respectant la taille des écoles, l'algorithme permet de réaliser des scénarios d'enclassement. L'implémentation des multiplicateurs de Lagrange offre une visualisation du "coût spatial" des infrastructures scolaires et des lieux de résidence des écoliers. La deuxième partie de cette thèse retrace les aspects principaux de trois projets réalisés dans le cadre de la gestion scolaire. À savoir : la conception d'un système d'attribution de subventions pour les transports publics, la redéfinition de la carte scolaire, ou encore la simulation des flux d'élèves se rendant à l'école à pied. *** May it be from an urbanistic, a social or from a governance point of view, the evolution of cities is a major challenge in our contemporary societies. By giving the opportunity to analyse spatial and social configurations or attempting to simulate future ones, geographic information systems cannot be overlooked in urban planning and management. In five years, the population of the city of Lausanne has grown from 134'700 to 140'570 inhabitants while the numbers in public schools have increased from 12'200 to 13'500 students. Associated to a considerable harmonisation process of compulsory schooling in Switzerland, this demographic rise has driven schooling services, in collaboration with the University of Lausanne, to set up and develop GIS capable of tackling various spatial issues. Established in 1989, the school districts had to be altered so that they might fit the reality of a continuously changing urban and political landscape. In a context of mobility and durability, an attribution system for public transport subventions based on the distance between residence and school and on the age of the students was designed. The implementation of these projects required the built of geographical databases as well as the elaboration of new analysis methods exposed in this thesis. The first part of this work focuses on the analysis of the city's pedestrian network. Its morphology is investigated through multi-scale approaches of the concept of centrality. The first conception, named the straightness centrality, stipulates that being central is being connected to the others in a straight line. The second, undoubtedly more intuitive, is called closeness centrality and expresses the fact that being central is being close to the others. The goal of the methods developed is to evaluate the connectivity and walkability of the network along with suggesting possible improvements (creation of pedestrian shortcuts).The third and final theoretical section exposes and develops an algorithm of regularised optimal transport. By minimising home to school distances and by respecting school capacity, the algorithm enables the production of student allocation scheme. The implementation of the Lagrange multipliers offers a visualisation of the spatial cost associated to the schooling infrastructures and to the student home locations. The second part of this thesis recounts the principal aspects of three projects fulfilled in the context of school management. It focuses namely on the built of an attribution system for public transport subventions, a school redistricting process and on simulating student pedestrian flows.
