Transit Oriented Development assessment of Handen Pendeltåg Station / Kollektivtrafikanpassad bebyggelse bedömning av Handen Pendeltågsstation

Covelli, Cristina January 2019 (has links)
Transit Oriented Development theoretical and practical framework represents an important tool for municipalities, private actors and citizens to enhance quality of life in urban contexts. Planning cities that encourage sustainable mobility patterns can contribute to aim at diversifying land use and making cities more accessible, safer and attractive for people. Handen has developed as a car-dependant area that is planned to growth its population and build more than 9000 new housing units by 2030 (Haninge Kommun, 2016). The TOD standard 3.0 was applied in the area around Handen pendeltåg station, to practically assess the TODness level of the area and provide recommendations to take into a consideration for future and current developments. Using the TOD standard in Handen can contribute to aim at a more sustainable growth pattern for both current and expected new citizens on the area. After implementing the evaluation system, it was found out that the best ranked variables were Compactness and Cycling. In contrast the variables that received the lowest scores were Walk, Densify, Connect, and Shift. Overall, Handen scored a Bronze level of TODness. Therefore, there are several actions that could be implemented on the study area in order to improve the TODness level. Specifically, Handen needs to diversify its land use, enhance the pedestrian network, encourage land mix use, decrease the space destined to cars and increase pedestrian connectivity, among others.

Zhodnocení havarijní připravenosti železniční stanice České Budějovice / Assessment of emergency preparedness at the railway station in České Budějovice

KLÍMA, Petr January 2011 (has links)
Emergency preparedness includes the ability to recognize the occurrence of extraordinary events and, in particular, planning, organizing and management of emergency measures to deal with them. The objective of this thesis is to assess planned measures to avert the consequences of accidents depending on selected extraordinary events in the premises of the railway station in České Budějovice. Another objective is to assess the overall emergency preparedness of the railway station in České Budějovice in this respect. In order to meet the objectives as well as possible I defined the following hypothesis: Planned measures to avert the consequences of accidents in the premises of the railway station in České Budějovice are adequate and in accordance with applicable legislation. The thesis includes basic general information on extraordinary events, emergency planning and the integrated rescue system, and then it describes securing emergency preparedness within the organizational structure of the entities involved. The thesis also includes the issue of rail freight transport and the related transport of dangerous substances. To achieve the objectives of the thesis and to verify the hypothesis, I used interviews with relevant experts from railway companies ČD as, ČD Cargo and SŽDC, and the study of available literature and legislation. Then, I used a document analysis aimed at assessing the adequacy and suitability of planned measures depending on the selected extraordinary events ? both associated with the normal operation of the railway station and the transport of hazardous substances in tanks. The analysis showed that the planned measures to avert the consequences of accidents in the premises of the railway station in České Budějovice are currently to a great extent adequate and in compliance with applicable national and international legislation. In the discussion section, I presented the problems that occurred in dealing with this issue. At the end of the thesis, I tried to propose some measures that would be suitable for adding into the documentation of emergency preparedness of the railway station in České Budějovice. I believe that this thesis will be used as a document monitoring an aggregate of measures to ensure emergency preparedness of the railway station in České Budějovice and, in the light of the thesis results, it will be possible to recommend further improvements in securing the preparation of these measures.

La gare, assurance métropolitaine de la ville post-industrielle. : Le retournement de valeur dans les projets urbains de quartiers de gare, à Saint-Étienne Châteaucreux et Liège Guillemins (Belgique). / The railway station as a metropolitan insurance in post-industrial cities. : Urban projects in railway station areas and the reversal of urban value. A comparison of Saint-Étienne Châteaucreux (France) and Liège Guillemins (Belgium).

Delage, Aurelie 21 March 2013 (has links)
Construction socio-spatiale héritée du XIXe siècle ayant connu un déclin dans la seconde moitié du XXe siècle, les quartiers de gare centrale dans les villes occidentales sont un support récent et privilégié de l’action collective urbaine. Les projets urbains que ces gares cristallisent présentent des programmations récurrentes reposant sur la mixité fonctionnelle et une orientation tertiaire affirmée. Cette thèse interroge le retournement de valeur symbolique et économique de ces espaces autrefois dévalorisés et aujourd’hui prisés. Quelles sont les modalités de la fabrique urbaine, comment se noue l’interaction nécessaire entre des acteurs publics ne pouvant intervenir seuls sur ces secteurs fortement contraints (notamment techniquement), et des acteurs privés parfois réticents à s’engager sur des marchés qu’ils jugent risqués ? En adoptant une approche inductive et qualitative, ce travail de recherche analyse la conception et la mise en œuvre de deux projets urbains aux avancements contrastés en raison de leviers d’action ou, au contraire, de points de blocages différents, dans deux anciennes villes minières devant négocier le tournant de la désindustrialisation (Saint-Étienne et Liège). Au terme de l’analyse, l’hypothèse d’une valeur assurantielle de la gare dans ces projets urbains est validée : en tant que ferment métropolitain vecteur de fortes potentialités, la gare centrale desservie par un train à grande vitesse est la condition de possibilité permettant d’enclencher non seulement la décision des acteurs publics mais aussi celle des acteurs privés, au premier rang desquels les promoteurs immobiliers, acteurs clés à l’interface entre l’action publique et l’investissement privé / The railway station areas of the 19th Century were a reflection of the Industrial revolution. Following a period of decay after the Second World War, the urban renewal of these areas is now one of the main concerns of local governments in European cities. In addition to a new railway station served by high speed trains, these urban projects are often based on functional diversity, including a business district.This thesis addresses the reversal of urban value in these specific urban areas, exploring how they have moved from repelling to attractive places. How do public and private actors interact, when the former cannot act alone in places constrained by physical barriers due to a lack of funding, and the latter are not inclined to invest in what they consider to be risky places?Our approach is both inductive and qualitative. The comparison of two projects in French and Belgian shrinking cities (Saint-Etienne, near Lyons, and Liège, near Brussels) allows us to understand what the levers for action are, and conversely what the bottlenecks are that slow down the implementation of the urban project around the station.As the result of our analysis, the railway station appears to be a positive and necessary factor for the reversal of urban value in these areas. It is a kind of insurance – in the same way as metropolitan areas create potentiality in the productive economy – both for public actors, as the railway station facilitates their mobilisation, and private ones, especially property developers, who are key elements in the relationship between public action and private investment

Ordonnancement des trains dans une gare complexe et à forte densité de circulation / Train platforming problem in busy and complex railway stations

Bai, Lijie 28 August 2015 (has links)
Cette thèse porte sur l'ordonnancement des trains dans les gares complexes en forte densité de circulation. L'objet se situe à la réalisation d'un outil pour aider les managers de la gare à générer un tableau des horaires sans-conflits dans un journée. Le management des circulations ferroviaires dans la gare demande l'ordonnancement soigneux pour adapter les ressources limités, en évitant les conflits entre les trains et satisfaisant l'objectif et les politiques économiques et de la sécurité en même temps. D'après les méthodes appliquées en recherche opérationnelle et les expériences professionnelles, une modèle mathématique applicable aux gares différentes est construit pour formaliser le problème de l'ordonnancement des trains contenant la topologie de la gare, activités des trains, contraintes de planification et objectives. Comme un problème à grande échelle, l'ordonnancement des trains dans un journée est décomposé en sous-problèmes traitables dans l'ordre du temps par sliding window algorithme accumulé. Chaque sous-problème est résolu par branch-and-bound de CPLEX. Afin d'accélérer le calcul des sous-problèmes, tri-level optimisation méthode est construit pour offrir une solution optimale locale dans un temps de calcul assez court. Cette solution est donnée à branch-and-bound comme une solution initiale.Ce système consiste à vérifier la faisabilité des horaires donnés à la gare. Les trains avec les conflits insolvables sont retournés à l'origine de ces trains avec les modifications des heures proposées. Déviations des trains commerciaux sont minimisées pour diminuer la propagation du délai dans le réseau ferroviaire. / This thesis focuses on the trains platforming problem within busy and complex railway stations and aims to develop a computerized dispatching support tool for railway station dispatchers to generate a full-day conflict-free timetable. The management of rail traffic in stations requires careful scheduling to fit to the existing infrastructure, while avoiding conflicts between large numbers of trains and satisfying safety or business policy and objectives. Based on operations research techniques and professional railway expertise, we design a generalized mathematical model to formalize the trains platforming problem including topology of railway station, trains' activities, dispatching constraints and objectives. As a large-scale problem, full-day platforming problem is decomposed into tractable sub-problems in time order by cumulative sliding window algorithm. Each sub-problem is solved by branch-and-bound algorithm implemented in CPLEX. To accelerate calculation process of sub-problems, tri-level optimization model is designed to provide a local optimal solution in a rather short time. This local optimum is provided to branch-and bound algorithm as an initial solution.This system is able to verify the feasibility of tentative timetable given to railway station. Trains with unsolvable conflicts will return to their original activity managers with suggestions for the modification of arrival and departure times. Time deviations of commercial trains' activities are minimized to reduce the delay propagation within the whole railway networks.
