都市發展固然帶動了經濟成長、生活舒適、交通便利等諸多正面效益，但隨著都市不斷向外發展之成果，卻也帶來了都市內的空間擁擠、交通壅塞、空氣汙染、生活環境惡化等現象，以及都市外的分散、無秩序蔓延發展等環境問題。為解決這些問題，都市規劃者提出大眾運輸導向發展理念。從都市化之觀點來看，發展大眾運輸導向能降低都市蔓延，提昇都市內之使用密度，減少私人運具之使用，進而降低能源消耗、改善空氣品質。然而，運輸建設具有改變土地使用模式與活動區位，進而帶動人口、產業在空間上重新分布的特性；當運輸建設的興建促使周邊都市活動頻繁時，少有研究探討到大眾運輸導向帶來的效益，是否會隨著人口、產業往捷運沿線聚集，反而使交通流量增加，進而造成空氣品質愈加惡化之問題。因此，本研究從捷運營運前後台北市空氣品質變化之觀點，以台北市433個里之1995年至2006年為研究範圍，以懸浮微粒為汙染變數，運用空間分析法和長期追蹤資料實證分析法，探討捷運、人口及產業三者對空氣品質之影響程度。 / 研究結果顯示，人口密度和就業密度對懸浮微粒濃度有顯著正向影響，因此，政府在推廣大眾運輸導向理念，鼓勵人口和產業往捷運沿線發展時，需有完善配套措施，否則將導致反效果－空氣品質的惡化。而有捷運經過之村里對懸浮微粒濃度有顯著正相關；但是分析各年度懸浮微粒可發現，台北市年平均懸浮微粒濃度下降，且隨捷運路網愈加完善，空氣品質愈好。因此，捷運建設雖造成沿線懸浮微粒濃度的上升，但卻降低了整體懸浮微粒濃度，提昇台北市空氣品質。 / Urban development is driven by economic growth, comfortable living, convenient transportation and other positive benefits. However, the results of urban development also brought crowdedness, traffic congestion, air pollution, environment degradation inside the city, and sprawl development out of the city. To solve these problems, urban planners proposed mass transit-oriented development (TOD) concept. From the perspective of urbanization, developing TOD can reduce urban sprawl, enhance the use of space inside the city, and reduce the use of cars. Further, these can decrease energy consumption and improve air quality. However, a transportation system can change the land-use patterns and redistribute the population and industries. Few studies have discussed whether the benefits of TOD will gather people and industries along the mass rapid transit (MRT), where results in the increase in traffic and more deterioration of air quality are inconclusive. Therefore, from the perspective of air quality varies over time in Taipei before and after the operation of MRT, this study uses spatial analysis and panel data analysis to investigate the impact of MRT, population and industry on air quality in 433 villages of Taipei City from 1995 to 2006. / The results show that population density and employment density have significant positive effects on the concentrations of PM10. Thus, when promoting the concept of TOD and encouraging the development of population and industry along the rapid transit, the Government should plan and implement the proper procedure; otherwise they will result in rising air pollution. The villages along the rapid transit have significant positive effects on the concentrations of PM10. However, analysis of the annual PM10 concentration can be found that the annual average has declined in Taipei City; the air quality will be better with a more extensive rapid transit network. Although the construction of transit system will cause the increase in the concentration of PM10 along the rapid transit, it has decreases the overall concentration of PM10 in Taipei City.

Le concept de transit-oriented development (TOD) est habituellement abordé en tant qu'ensemble fixe de caractéristiques physico-spatiales. Cette approche ne s'avere pas suffisante pour comprendre comment le TOD peut être pertinent pour coordonner les transports et l'urbanisme dans un contexte urbain concret. Afin de combler cette lacune, nous proposons d'étudier le TOD en tant qu'instrument d'action publique, adopté, produit et utilisé par les acteurs sur le territoire en fonction des enjeux, des ressources et des contraintes qui y sont présents. Ce travail exploratoire est fondé sur une étude de cas de la mise en place du TOD a Sainte-Thérese. Pour comprendre comment se sont arrimés les intérêts des acteurs impliqués et ce qui en a résulté, la collecte de données se fait a l'aide de sources écrites, mais aussi d’entretiens semi-directifs avec les acteurs clé. Les résultats de l'étude confirment la pertinence de l'approche adoptée pour aborder le TOD. Le TOD comme instrument d'action publique peut être qualifié d'opérateur de congruence, car il permet de faire converger les intérêts différents, et même potentiellement contradictoires, qui sont en jeu sur le territoire. Cependant, il n'y a pas de formule passe-partout: la production du TOD se fait en grande partie de façon incrémentale, en fonction des conditions sur le territoire. La mise en place du TOD n'exige pas nécessairement l'invention d'un nouveau cadre d'action et peut se faire en grande partie a l'aide des outils existants. Toutefois, pour pouvoir se servir pleinement de ces outils, le leadership des acteurs clé s'avere crucial. / The concept of transit-oriented development (TOD) is usually defined as a reproducible combination of certain physical and spacial characteristics. This definition does not however allow for a full understanding of how this general concept can be relevant for coordinating land-use and transportation in a given urban context. Our research seeks to address this issue and proposes to study TOD as an urban policy instrument, the choice, the production and the usage of which is defined by the goals, the resources and the constraints in a particular territorial context. This exploratory research is based on a case study of the TOD implementation in Sainte-Therese (Quebec). In order to understand how the different interests at play were aligned, and what resulted thereof, we consulted written sources and conducted semi-directed interviews with people who were actively involved in the TOD implementation. The results of our study confirm the relevance of this analytical approach to study TOD. One of the virtues of TOD as a policy instrument is that it allows to aggregate various, even potentially contradictory, interests at play. However, it does not offer a universally applicable formula: the TOD implementation is to a great extent conducted incrementally, according to local conditions. This process does not necessarily require the invention of a new public policy framework and can largely be done with the help of existing tools. Nevertheless, in order to fully make use of those tools in the course of TOD implementation, the organizational leadership in land-use and transportation agencies is crucial.

Le développement axé sur le transport en commun (transit-oriented development ou TOD) est un concept urbanistique souvent proposé comme solution aux problèmes associés à l’étalement urbain. La majorité des recherches sur ce concept sont descriptives ; rares sont les études qui examinent l’impact des projets de TOD sur les comportements en transport. Certains chercheurs proposent d’étudier les raisons qui expliquent la rareté de véritables TOD en Amérique du Nord. Cette approche s’appuie sur l’hypothèse que ce manque d’exemples est le résultat d’une faible demande, ou d’une multiplicité de barrières, quelles soient financière, réglementaire, politique, organisationnelle ou structurelle. Notre étude s’inscrit dans ce courant, afin d’examiner le développement de TOD dans la région métropolitaine de Montréal. L’étude empirique se concentre sur la perspective des promoteurs immobiliers quant à l’ampleur de la demande et des barrières à l’offre de TOD. La méthodologie de notre étude consiste en des entrevues avec les promoteurs immobiliers travaillant dans la banlieue montréalaise. Les résultats montrent que la demande est en croissance pour les produits ayant certaines caractéristiques de TOD, mais que la demande pour des TOD reste faible. Deux barrières principales ressortent de cette étude, soit le manque de terrains et l’offre insuffisante de service de transport en commun. On peut identifier d’autres obstacles majeurs dont le manque d’une définition commune du TOD et une structure de l’industrie de l’industrie mal adaptée à ces formes de développement. L’étude conclue que la réalisation de TOD dans le contexte montréalais requiert que les acteurs gouvernementaux assument un rôle plus proactif et visionnaire. / Transit-oriented development or TOD is an urban planning concept that is often proposed as a solution to the problems associated with suburban sprawl. The majority of research on this concept is descriptive; some authors examined the effect of TOD pro-jects on travel behaviour. A new research approach proposes to investigate the rarity of examples of veritable TOD in North America. This approach proposes that the lack of examples is either the result of a weak demand, or of a variety of supply barriers catego-rized as financial, regulatory, political, organizational or pertaining to the physical con-text of the city. Our study applies this research approach in order to examine the development of TOD in the Montreal metropolitan region. The empirical study focuses on the perspec-tive of real estate developers regarding the degree of demand and the supply barriers to TOD. The methodology consists of interviews with a diverse group of real estate devel-opers working in the Montreal suburbs. The results demonstrate that the demand is growing for products having certain characteristics of TOD, but that this does not reveal a demand specifically for TOD. We also determine that the two principal supply barriers are the lack of land and the insufficient supply of public transit service. Other major obstacles include lack of a common definition of TOD and the structure of the land de-velopment industry which is not well adapted to this form of development. The study concludes that the realization of TOD in the Montreal context requires that provincial and municipal government actors assume a more proactive and visionary role.

This study examines potential transportation improvements in the Elysian Fields Avenue Corridor, and the benefit that these improvements may produce. Data for the study area are compiled and analyzed. Conceptual plans for the implementation of different transit technology alternatives were developed and assessed in terms of user benefits, cost, potential land use impacts, potential economic impacts, and feasibility. Case studies and relevant literature are reviewed. The intent of this thesis is to provide an overview of the study area prior and subsequent to Hurricane Katrina, develop plans for the implementation of transit alternatives in the Elysian Fields Avenue Corridor, and assess potential costs and benefits of the different alternatives developed.

The word revise means to reconsider or modify as with text. If we think of the suburban landscape as a text, the culture of each era left documentation of their values, policies and way of life in the form of transportation networks and other infrastructure, such as Main Streets, squares and public buildings. While evidence of most of the everyday life of individuals of every era gets erased by the following era, infrastructure investments of each era are adaptively reused and remain to tell the story. This thesis documents the adaptive reuse of these suburban frameworks and develops a proposition for the appropriate next layer to accommodate a new culture of inhabitants. Focusing on second generation suburbs, using Gwinnett County as a case study, this analysis identifies three problems of the current suburban situation: the problem of abandoned strips, a demographic shift, and the need for place. As new strip highways develop, old strips decline leaving abandoned shopping centers and declining property values. New development continues to move north and out of the county, and middle class residents, for which existing auto-oriented suburbs were created, move as well. A new, poorer, and more ethnically diverse population inherits the auto-oriented landscape left behind. This phenomenon is particularly concentrated along the southern portion of the Buford Highway corridor. Those with more money move closer to new development, while those with less money have less choice and are found near declining strips with fewer services, poorer quality housing and lower quality of life. Finally, county officials have expressed a desire for defining "the epicenter of Gwinnett." I believe that there is no one "center" of Gwinnett, but a series of places defined by memory, design or events. I propose to improve the situation of these three problems with a light rail line that connects existing places and creates new walkable, livable places to improve quality of life. This connective piece will serve as a social condenser in lieu of a center, provide links between polar populations, and reactivate declining strips while creating a sustainable infrastructural spine for future growth in the region.

伴隨著永續發展思潮之興起，「大眾運輸導向發展（Transit-oriented development, TOD）」已成為都市規劃之重要理念。相關研究雖曾就TOD緊密、混合使用發展帶來之永續效益進行探討，然高密度之發展模式亦會加速都市內資源消耗，並影響生活環境品質。為解決前述課題，相關文獻因而提出「綠色大眾運輸導向發展（Green transit-oriented development, Green TOD）」理念，以期待在TOD與綠色都市主義（Green urbanism）之結合下，形塑更為友善環境發展之都市型態。國內外雖有相關研究對Green TOD之規劃理念進行探討，並建立評估架構與準則，然規劃上仍未以該理念建構土地使用規劃模式，以協助規劃者研擬規劃方案；此外傳統土地使用規劃模式建構亦較少將土地使用配置現況與變更限制納入考量，規劃模式因而無法反映實際之規劃問題，並使其應用受到限制。 　　基此，本研究係由通盤檢討面向切入建構「綠色大眾運輸導向土地使用規劃模式」，規劃上並以高密度發展、混合使用配置、親生物開放空間追求、非機動運具可及性提升、停車需求抑制、資源配置效益追求、都市機能健全發展為追求目標建構多目標規劃模式；模式考量限制則包含通盤檢討變更可行性、配置區位限制、規模與容量限制、預算限制、運輸場站自明性、自行車道連續性等；模式求解則修正最小偏差法，並設定不同之權重組合尋求非劣解集合；最後則模擬實例情境設計假想例，以測試模式之可用性，並透過敏感度分析探討規劃模式之應用特性。 　　研究結果發現，規劃模式部分目標因追求方向相同而不具有償付關係，然各目標規劃理念、衡量面向與決策內容皆有不同，規劃上因而有保留之必要性，規劃模式並可依據此特性追求整合性之規劃效益，且著重高密度發展策略之應用。而敏感度分析則顯示，預算額度多寡將影響模式之規劃彈性與償付關係之表現程度，規劃前應妥善分析土地使用配置現況後編列適當之預算資源，以確保規劃偏好達成。本研究建構之土地使用規劃模式可於Green TOD 理念下研提不同之替選方案，並輔助規劃單位進行土地使用、自行車路網、水資源配置之規劃作業。 / Transit-oriented development (TOD) has become a main concept of urban planning as the advocacy of sustainable development. Previous studies, though, have explored the benefit of TOD which features of compact development and mixed land use, excessive density would also accelerate the resources consumption in inner city and decrease the quality of living environment. To solve the aforementioned problems, studies have proposed the concept of “Green transit-oriented development (Green TOD)”, which combines the concepts of “TOD” and “Green Urbanism” in anticipation of shaping an environmentally friendly urban form. However, most of the studies about Green TOD mainly focus on defining the planning concept or establishing the evaluation framework and criteria of it, it still lacks a land use planning model for Green TOD which aims to generate planning alternatives objectively for planners. With regard to the land use planning model, prior studies seldom took the current zoning and rezoning restriction into consideration during the model formulation, which not only made the formulated model fail to represent the real planning problem but also decrease the application value. This study, therefore, develops a multi-objective land use planning model for Green TOD from the aspect of overall review of urban planning. The objectives of the model include “maximizing the development density”, “maximizing the mixed land use degree”, “maximizing the biophilic open space”, “maximizing the accessibility of non-motorized vehicle”, “minimizing the parking demand”, “maximizing the benefit of resource allocation” and “minimizing the rezoning scale of available land”. The constrains of the model include “the rezoning feasibility of overall review”, “the restriction of allocated location”, “the allocated restriction of minimum scale and maximum volume”, “budget limitation”, “identification of transit station area” and “connectivity of bikeway network”. The revised minimum deviation method with different weight settings was used to search the non-inferior solutions set for the simulated case to verify the applicability of the developed model. Besides, sensitivity analysis was used to explore the model characteristic. The result found that some of the objectives, which cannot be integrated due to the difference of planning concept, assessing aspect and decision contents, feature of non-trade-off relationship due to the same pursuing direction. The application of the model can therefore apply this characteristic to pursue the integrated benefit accordingly and focus on the planning approach of high density development. Besides, the sensitivity analysis showed that budget amount influences the planning flexibility and trade-off degree significantly. Budgeting should therefore be dealt appropriately after analyzing the current zoning to ensure the achievement of planning preference. The land use planning model developed by this study can be applied to generate planning alternatives under the planning concept of Green TOD and support the authorities for land use allocation, bikeway design and water resource allocation.

Baltimore fait partie des grandes métropoles américaines qui se sont lancées dans le cercle vertueux du développement durable. Traditionnellement acquise aux votes démocrates, constituée d’une majorité d’Afro-Américains appartenant aux classes sociales défavorisées, et portant les profonds stigmates de la crise industrielle et des récessions économiques successives, la ville offre un terreau favorable aux expériences de gestion urbaine intégrant la notion de durabilité. Bien plus, tant du point de vue des caractéristiques économiques et démographiques que de celui de l’héritage marqué de la ségrégation, c’est la dimension sociale du développement durable et la justice environnementale qui sont en jeu. Depuis 2000, la municipalité a initié deux grands projets intégrant le développement durable dans ses dimensions de « sustainability », « livability » et « smart growth », pouvant être regroupées sous l’appellation de « green politics ». L’essentiel de ses efforts porte sur la revitalisation de deux ghettos du centre-ville tombés en complète déshérence, East Baltimore et West Baltimore. Nous concentrerons notre réflexion sur deux exemples précis de « green politics » (la réhabilitation d’une partie du ghetto d’East Baltimore avec le Grand Piano ; la Red Line, ligne de train qui doit relier les deux ghettos et des zones de friches industrielles au quartier des affaires). À partir de ces exemples, nous étudierons les modes de gouvernance mis en place et le rôle joué par les différents acteurs qui y participent (« anchor institutions », grandes fondations, acteurs publics et associations de quartier). Nous nous interrogerons sur l’émergence de formes inédites de citoyenneté façonnées par ces nouveaux modes de participation à l’aménagement urbain durable. Il s’agira de comprendre si le développement durable est conçu au service des habitants du ghetto afin de lutter contre la pauvreté et les injustices sociales et environnementales, ou si, au contraire, la racialisation de ce concept favorise la gentrification, crée de nouvelles formes de ségrégation et aboutit à la fin programmée des ghettos. / Baltimore is part of the big American metropolises committed in a race for sustainable development. Traditionally a democratic stronghold, with a majority of city dwellers who are poor Afro-Americans, and harshly battered by the industrial crisis and the economic recession, Baltimore City is the perfect laboratory for urban planning projects experimenting sustainable development. Furthermore, with regard to its economic and demographic characteristics and the importance of segregation in the city, the social dimension of sustainable development and the issue of environmental justice are at stake. Since 2000, the Mayor and the City Council initiated two ambitious projects integrating the various aspects of sustainable development (« sustainability », « livability » and « smart growth »), which are all belonging to « green politics ». These efforts are focused on East Baltimore and West Baltimore, two huge ghettos surrounding the financial district in the downtown area. The core of our analysis concerns two projects of green politics (the rehabilitation of a part of the East Baltimore ghetto through the Grand Piano; the Red Line, a train connecting the ghettos, some industrial wastelands and the Central Business District). Through these examples, we will put under study the types of urban governance and urban regimes at work, and the role played by the different stakeholders (« anchor institutions », philanthropic foundations, public actors and neighborhood associations). New forms of citizenship may appear with unheard modes of participation to sustainable urban planning. Sustainable development may be an opportunity to improve the living conditions in the ghetto and fight against poverty and social and environmental injustices. The seamy side of the story may be a racialization of sustainable development nourishing gentrification, creating new forms of segregation and bringing about the death of the ghettos.

Abstract Station-nearness principles as we will discuss in this paper, deals with the coordination of urban functions with the public transportation network. When we talk about functions, we mean residences, workplaces, commercial services, entertainment venues, places of culture, etc. These functions should be high density, there should be a mix of them and they should be pedestrian friendly in nature. Effective integration of functions around train stations brings many benefits and is one of the best means by which you can increase public transport use and increase the accessibility for people in a region. More and more, cities in North America, Europe and other places, are exploring the idea of how this concept can be applied. The Copenhagen region as we will discuss, has placed station-nearness principles at the forefront of their finger plan. Since the Copenhagen region has applied these principles, they have seen clear results with increased public transit ridership, as well on the overall, an increase in the standard of living. As many places are exploring the concept, not everyplace has been able to make the concept work. When we look at Scania, the concept is under utilized to a degree. There continues to be many populated and dense areas in Scania where the coordination of urban functions with public transit is lacking. The automobile is also gaining stronger competition over public transportation; this is a concern in terms of the sustainable future and quality of life for the region. It is not always the solution to simply expand the public transportation network, rather it can be significant to explore more upon the concept of station-nearness principles so that the existing public transit network can be made more effective. It is important to compare places, see in our case study how the concept has worked in the Copenhagen region and look into why the concept is lacking in Scania, as well, what can be done to implement it more in Scania. It is also important how the Öresund region as whole, can play a role with developing the concept, as well, how the concept can benefit the Öresund region vice versa.

This thesis identifies and explores the effects that new parking strategies and policies could have on transit-oriented development (TOD) success levels. Additionally, it makes the case for TOD parking regulation reform, and is designed to educate planners and stakeholders on how to successfully and responsibly shape parking regulation in the planning and implementation process, so that land use in the region allows the synergistic provision of sustainable transportation specifically to the Boston region. Transit-Oriented Development is viewed and defined differently throughout research and literature, with its most common traits being compact, mixed use development near transit facilities and high-quality walking environments. Due to automobile dependency in the United States, developments (including TOD) are required to provide a specific level of parking to accommodate automobile usage. Excessive provision of parking decreases urban density, walkability, housing affordability, and transit ridership. In order to comply with governmental regulations and still meet TOD goals and objectives, expensive measures such as parking garages are implemented to accommodate automobile users, leading to a less affordable development and smaller profit margins for developers. An assessment of land use characteristics around transit stations, literature pertaining to TOD and current parking regulations and policies is conducted. Best practices and strategies are proposed with the overall goal of decreasing automobile-dependency and its impacts on the urban environment. Due to TOD’s heavy reliance on extensive transit systems, the focus of the study is specifically on the 101 cities and towns in the Boston metropolitan region. Somerville, MA, which contains previous transit-oriented developments and future projects in the design process, is used as a case study for transit-oriented development.
