Diretrizes de planejamento estratégico de uso e ocupação do solo urbano para portos secos / Strategical planning guidelines of urban land use and occupation for dry ports

Evandro Cardoso dos Santos 17 September 2004 (has links)
Este trabalho mostra os resultados obtidos durante as atividades de pesquisa e levantamento de dados sobre os equipamentos urbanos de carga denominados Estações Aduaneiras Interiores (EADIs), conhecidos como Portos Secos, na identificação de impactos ambientais resultantes das operações portuárias desses estabelecimentos. O conflito na utilização do espaço viário da área urbana por modos e sistemas de transporte de carga, incumbidos da tarefa de movimentação e transporte de mercadorias dos Portos Secos nas cidades brasileiras, especialmente aquelas de maior porte e em regiões metropolitanas, a saber, caminhões e trens, leva à preocupação tanto pela inexistência de uma legislação específica locacional para estes equipamentos impactantes, como pela grande disseminação destes empreendimentos, especialmente na década de 1990. Aspectos operacionais como a movimentação de cargas e intermodalidade de transportes nas áreas dos Portos Secos, as atividades produtivas urbanas e regionais e a utilização dos Portos Secos, a concentração desses equipamentos nas periferias industriais urbanas das maiores cidades do país, a utilização do sistema viário principal urbano para a viabilização do transporte de cargas, a localização dos Portos Secos e a logística empresarial, entre outros, chamam a atenção num contexto onde o transporte de cargas e o cumprimento das leis geradas pelas políticas governamentais e de regulamentação ainda não reconhecem as necessidades reais das cargas urbanas no Brasil. Aspectos de planejamento para os projetos dos Portos Secos e a atenção à circulação de cargas no ambiente urbano, frente ao uso e ocupação do solo, determinados pelas leis municipais e à infra-estrutura urbana existente, calcados exclusivamente nos custos operacionais e na acessibilidade, subsidiam este trabalho na formulação de diretrizes de planejamento estratégico de uso e ocupação do solo urbano para Portos Secos, para a redução dos impactos ambientais negativos dos transportes urbanos de cargas. Os principais impactos ambientais, que afetam (de forma mais aguda) a área urbana que hospeda o Porto Seco, especialmente nos casos onde não há um estudo de pré-viabilidade e compatibilização do equipamento ao uso e a ocupação do solo, bem como sua adequação às regras do Planejamento Urbano relacionado ao Planejamento dos Transportes tanto nos ambientes físico, natural, político, legal e de planejamento quanto no ambiente sócio-econômico. Examinar o funcionamento de um Porto Seco - EADI Ribeirão Preto - e sua relação impactante na área urbana onde atua, sua movimentação de cargas e prestação de serviços, levando em conta os custos econômicos diretos e indiretos para diferentes atividades, especialmente os custos e impactos ligados aos ambientes natural, social e econômico, faz parte de um diagnóstico a ser elaborado a partir de indicadores de qualidade de funcionamento da área urbana. Os problemas da localização dos Portos Secos induzem a formulação de diretrizes de planejamento estratégico de uso e ocupação do solo que auxiliem na minimização dos impactos ambientais causados durante a realização das tarefas de armazenamento, manuseio, distribuição e transporte de cargas. Os resultados aqui apresentados poderão ser de grande pertinência e utilidade para o poder público na formulação de um quadro legal e de regulamentação e para o segmento empresarial ansioso por melhores decisões estratégicas. Este trabalho apresentará dados, imagens, mapas, tabelas, gráficos, entre outros, tornando-se mais dinâmico na leitura e compreensível no aporte teórico. / The present work brings forth the results of the research and data colleting activities on the freight urban equipment called Interior Custom Stations (ICSs), named EADI in portuguese, also known as Dry Ports, in the identification of the impact the operations carried out in these stations may have on the environment. The problematic use of the urban locomotion spaces by trucks and trains, the modes and systems of freight transportation in charge of moving and transporting freight from the Dry Ports to Brazilian cities, especially the larger and metropolitan ones, in troublesome for the lack of specific local legislation for such impact equipments as well as for their spread in Brazil specially in the 1990th decade. Operational aspects like freight moving and transport intermodality in the Dry Port areas, productive urban and rural activities and the Dry Ports usage, the concentration of these equipments in country\'s larges cities urban industrial outskirts, the location of the Dry Ports and business logistics, among others, call our attention in a context where freight transporting and the fulfillment of the laws created by government and regulation policies still do not understand the real needs of urban freight in Brazil. Planning aspects of the Dry Ports\' Projects together with the attention to the circulation of freight in urban surroundings in face of both use and occupation of the land determined by Municipal laws and the existing urban infra-structure (based exclusively on operational costs and accessibility), support this research in the formulation of strategic planning guidelines of use and occupation of urban land for Dry Ports towards the reduction of negative environmental impacts of urban freight transporting. The major environmental impacts affect (in a more direct way) the urban area that houses the Dry Port, most visibly in cases when there are no studies on the pre-viability and compatibility of the equipment to the use and occupation of the land, as well to its adequacy to the rules of Urban Planning concerning Transport Planning in the physical, natural, political, legal and socio-economical ambience. A close examination of a Dry Port - EADI Ribeirão Preto -, its important relation to the urban area where it is placed, the moving of freight and services offered there taking into account the direct and indirect economic costs for different activities, above all the costs and impacts related to the natural, social and economic ambience, is a part of a diagnosis to be elaborated from the urban functioning quality indicators. The problems in the Dry Ports location lead to the formulation of strategic planning guidelines for the use and occupation of land, which may help minimize environmental impact from storing, handling, distribution and transportation activities. The results brought forth in this work may be of great relevance and usefulness to the government in the formulation of a legal and regulative policy to the business park, longing for better strategic decisions. The present work brings forth data, images, maps, tables, charts, among other kinds of information, which makes its reading more dynamic and understandable in its theoretical discussion.

Modelagem, mensuração e simulação do movimento de pedestres e veículos

Silva, André de Souza January 2010 (has links)
Analisar a probabilidade dos tecidos urbanos exercerem efeitos junto ao movimento de pedestres e veículos, por meio do desenvolvimento de um modelo matemáticoestatístico e, aplicar na prática do planejamento urbano as informações obtidas, são os objetivos que se apresentam. O problema central está em distinguir quais propriedades são relevantes, que relações mantêm entre si, e o quanto explicam o porquê, como e por onde pedestres e veículos se movimentam? Parte-se da hipótese de que propriedades espaciais, formais e funcionais dos tecidos urbanos vinculadas ao sistema de vias, quadras, lotes e edificações, de alguma maneira e intensidade, facilitam, dificultam ou mesmo definem significativamente o movimento de pedestres e veículos, cuja consideração em conjunto e em separado aprimora a modelagem, mensuração e simulação do movimento de pedestres e veículos. As abordagens centradas na demanda de viagens (Entrevista Domiciliar de Origem e Destino) e na configuração espacial urbana (Sintaxe Espacial) fundamentam teoricamente a pesquisa e embasam a construção do método que compatibiliza e conjuga, por meio da construção do modelo matemático-estatístico, denominado modelo de deslocamento 5D, cerca de 20 variáveis do tecido urbano. Em relação aos resultados obtidos, as abordagens adotadas se mostram complementares no entendimento das propriedades que influenciam o movimento de pedestres e veículos em torno dos bairros Higienópolis, Santa Maria Goretti, Passo D’Areia e Vila do IAPI, em Porto Alegre, tomados como estudo de caso. O modelo de deslocamento 5D mostra-se operacionalmente viável e promissor, apresentando resultados estatísticos significativos e com alto grau de confiabilidade. Aproximadamente, 85% do movimento de pedestres e veículos nas áreas em estudo é explicado por medidas que consideram: (i) a articulação e continuidade de percursos alternativos possíveis ao longo de uma via em relação as demais vias em seu entorno imediato; (ii) a contribuição das edificações e dos recuos laterais e frontais em relação aos lotes e quadras na conformação do espaço aberto público; (iii) a variedade de tipologias edilícias e possibilidades de combinação entre si e ocorrência de morfologias simultaneamente; (iv) a relação entre movimento, área construída e comprimento de via; (v) a atribuição de valores às diferentes atividades residenciais e não-residenciais desempenhadas nas edificações; e, (vi) a ponderação dos acessos às edificações. A aplicação do modelo de deslocamento 5D demonstrou ser um instrumento útil na simulação de condições de total transformação ou relativa homogeneidade dos tecidos urbanos, assim como auxiliar ao planejamento urbano, não determinando, entretanto, o que deve ser feito, mas sim, possibilitando entender o que está sendo feito. / An analysis of the likelihood of the urban tissues to exercise effects over pedestrian and vehicle movements, through the development of a statistical and mathematical model, and the practical application of the resulting information, are the intended objectives. The core problem consists in distinguishing which properties are relevant, what are their relations with one another, and to what extent they explain why, how and where pedestrians and vehicles move along? The assumed hypothesis is that spatial, formal and functional properties of the urban tissues linked to the system of lanes, blocks, lots and constructions, in some way or intensity, facilitate, impair or even define significantly the movement of pedestrians and vehicles, whose joint or separate consideration improves the modeling, measuring and simulation of pedestrian and vehicle movement. The approaches focused on traveling needs (Origin and Destination Domicile Interview) and in the urban space configuration (Space Syntax) lay the theoretical foundation for the survey and are the basis for the construction of the method that makes compatible and conjugates, through the construction of the mathematical and statistical model, called 5D displacement model, about 20 variables of the urban tissue. With regard to the results obtained, the adopted approaches show entirely in the understanding of the properties that influence the movement of pedestrians and vehicles surrounding the districts of Higienópolis, Santa Maria Goretti, Passo D’Areia and Vila do IAPI, in Porto Alegre, taken as case study. The 5D Displacement Model proves operationally viable and promising, presenting significant statistical results with a high degree of reliability. Approximately 85% of the movement of pedestrians and vehicles in the studied areas is explained by measures that consider (i) articulation and continuity of alternative routes available along a lane with regard to the other lanes on the immediate surrounding; (ii) the contribution of the buildings and lateral and frontal gaps with regard to the lots and blocks in the conformation of open public space; (iii) a variety of edilicious typologies and possibilities for combinations among themselves and the occurrence of morphologies simultaneously; (iv) the relation between movement, constructed area and length of lane; (v) the attribution of values to the different residential and non-residential activities performed at the buildings; and, (vi) and the ponderation of accesses to the buildings. The application of the 5D displacement model proved to be a useful tool in the simulation of total transformation conditions or the relative homogeneity of the urban tissues, while helping with urban planning, though without determining what should be done, but making it possible to understand what is being done.

O poder público planejando intervenções viárias : uma abordagem configuracional no Distrito Federal e entorno

Santos Júnior, Reinaldo Germano dos January 2014 (has links)
Esta dissertação aborda o tema das intervenções viárias planejadas pelo poder público e seu impacto na configuração espacial. O sistema viário é fator fundamental na estruturação espacial urbana, na medida em que interfere na maior ou menor facilidade de se acessar determinados espaços, privilegiando certos locais em relação ao movimento, por exemplo. Ao poder público cabe a tarefa de planejar e promover intervenções viárias e de transporte. Tais intervenções vêm associadas a outras transformações, em especial, no movimento e no uso e ocupação do solo. Embora haja consciência de que alterações no sistema viário estejam relacionadas a muitas outras transformações urbanas, uma análise ampla dessas inter-relações é tarefa bastante complexa. O objetivo deste trabalho é analisar intervenções viárias planejadas pelo poder público visando avaliar seus impactos na configuração urbana e associá-las a possíveis desdobramentos em termos de movimento e diversificação do uso do solo. Também pretende-se discutir como as propostas institucionais de ordenamento territorial se articulam com as intervenções viárias planejadas. Toma-se para o estudo empírico a região de Brasília, englobando o Distrito Federal e seu Entorno imediato. São enfocados dois planos recentes: o Plano Diretor de Ordenamento Territorial do Distrito Federal, PDOT e o Plano Diretor de Transporte Urbano e Mobilidade para o Distrito Federal e Entorno, PDTU, dos anos de 2009 e 2011, respectivamente. O trabalho desenvolve uma análise comparativa da situação atual (sem intervenções) com a situação proposta (com intervenções), a partir de metodologia baseada na Sintaxe Espacial. As medidas sintáticas de Integração Angular Global e Escolha Angular são tomadas respectivamente como indicadores de acessibilidade e hierarquia. Os resultados apresentam as principais transformações detectadas em termos da configuração e do potencial de movimento, destacando-se pontos de coerência e também algumas inconsistências entre as propostas de estruturação viária e uso do solo dos dois planos considerados. Nas conclusões, enfatiza-se a importância de análises desse tipo, visando melhor compreender a relação entre o sistema viário e a estrutura espacial das cidades, dando suporte a um planejamento territorial e de transporte mais articulado. / This thesis addresses the issue of government-planned road interventions and their impact on space configuration. The road system is a fundamental factor in urban spatial structure, in that influences the ease of access to certain areas, privileging certain places in relation to movement, for example. The government has the task of planning and promoting road and transport interventions. Such interventions have been associated with other transformations, especially in relation to movement and land use. While it is understood that changes in the road system are related to many other urban transformations, an extensive analysis of these interrelationships is a very complex task. The objective of this study is to analyze planned road interventions by public authorities to assess their impacts on urban configuration and associate them with possible consequences in terms of movement and diversification of land use. It also examines how institutional proposals for land use are linked to planned road interventions. The case study being examined comes from the metropolitan region of Brasilia, which encompasses the Federal District and its surrounding areas. In particular, two government planning document are analyzed: The Master Spatial Plan of the Federal District (PDOT) from 2009 and the Master Plan for Urban Mobility and Transportation for the Federal District and surrounding areas (PDTU) from 2011. The thesis develops a comparative analysis of the current situation (no intervention) with the proposed situation (with interventions) based on Space Syntax. Syntactic measures of Angular Global Integration and Angular Choice are taken as indicators of accessibility and hierarchy. The results show the main changes detected in terms of urban configuration and movement potential, highlighting points of consistency and also some inconsistencies between the proposed road structure and the land use of the two plans considered. The conclusion emphasizes the importance of this type of analysis to better understand the relationship between the road system and the spatial structure of cities and argues that land use and transport planning need to be more closely integrated.

Non Motorized Transport Planning for an Indian City

Rahul, T M January 2015 (has links) (PDF)
Indian cities are currently facing various transportation issues like congestion, pollution, urban inequity, high fatality rate due to accidents etc. because of an increase in the ownership of private motor vehicles and their usage. This has prompted many policy makers to search for alternate modal options that are more sustainable than motorized modes. Non Motorized Transport (NMT), which includes mainly walking and cycling in an urban context, do not produce many of the issues associated with motorized modes like congestion, pollution, fatal accidents etc. But, promotion of NMT requires a clear-cut planning strategy, with a lucid understanding of various strategies and their effect on the NMT usage. Present study tries to answer certain pertinent questions, particularly with respect to walking and cycling, which can arise while preparing a plan for promoting NMT in Indian cities. The following are the questions that the author seeks to answer in the present study. 1) Which are the areas inside a city that a planner shall target for promotion of NMT?2) Where shall a planner locate the infrastructures for NMT in these areas?3) What may be the possible impacts of providing these NMT facilities?4) What may be the possible effect of built environment factors on the choice of NMT? Providing NMT infrastructures requires knowledge of location characteristics such as the trip distance of NMT. Present study tries to elicit the existing distance characteristics of walking and cycling in terms of an acceptable trip distance. The household travel data of Bangalore city, for the year 2009, are used in the study. First, a description and a statistical analysis of the walking and cycling trip distances across the subcategories of socio-demographic and regional factors is done. Secondly, the acceptable distance is computed from the cumulative trip length distribution based on the results of the statistical analysis. The socio-demographic and regional factors used in the study include purpose, age, gender, educational level, occupational status, and motor vehicle ownership. The major results include a significant difference between the mean trip distances on foot for the subcategories of variables such as gender (z value, 4.94), whether the respondent owned a private vehicle (z value, -21.2), and whether the trip was made inside the Central Business District (CBD) (z value, -3.93). One of the major implications of this study pertains to requirement of a footpath around main activity centers like bus stations, at least up to a distance of 1385 meters (maximum value for walking as the main mode) and around the bus stops, at least up to a distance of 750 meters (maximum value for walking as the access mode). Next, the present study analyzes the influence of built environment factors –density and diversity -on the mode choice and trip distance of the residents in the Bangalore city. The built environment factors are analyzed, for their marginal effects in the presence of various socio-demographic and alternative attributes, for the two segments -respondents owning at least a personal vehicle and respondents not owning any personal vehicle. The density used is the total density, which was the sum of population density in a zone and employment density in a zone. The diversity index, which was an explainer of the land-use mixture, was set such that, when a zone with small area had employment opportunities comparable with its population, the diversity index would be high. When tested on a holdout sample other than the ones used in the estimation of the mode choice model, for the vehicle-owning group, the model estimated produced a validation accuracy of 93% and 91% respectively for two-wheelers and walking. For the vehicle non-owning group, the prediction success rate was highest for walking (97%), and lowest for public transit (84%). For the vehicle non-owning group, an increase in the density increased the trip distance (parameter values of 0.016 for total density at origin and 0.002 for total density at destination) and decreased the NMT usage (parameter values of -0.036 and 0.038 respectively for cycling and walking for total density at origin, and -0.092 and 0.073 respectively for cycling and walking for total density at destination), but for the vehicle-owning group, the inverse was true. The results for the vehicle non-owning group highlighted the requirement of a policy framework to control the employment and housing location of them in order to reduce their trip distance. In the mode choice model for the personal vehicle-owning group, the similarity between the parameters of the built environment factors across the two-wheeler and NMT reflected the need for adopting policies that would change the attitude of people towards NMT. Also, the trip distance model determined that females preferred a shorter working distance, with a parameter value -0.109 for the vehicle-owning group and -0.04 for the vehicle non-owning group, when compared with males. Lastly, the study develops a methodological framework to determine the sustainability impact on providing NMT infrastructures using a Composite Sustainability Index (CSI). More specifically, the study develops a methodological framework to determine the variation in the CSI on providing NMT -walking and cycling – infrastructure. The methodology establishes a link between the proposed NMT infrastructures and the CSI using two explanatory indicators: 1) number of motorized vehicles and 2) vehicle-kilometers travelled by the motorized modes. The main components of the framework include the estimation of a mode choice model for a study area, calculation of the explanatory indicators for the scenarios before and after providing NMT infrastructures, and determination of the sustainability impact. The proposed framework, along with the acceptable distance determined in the earlier step, is then used to determine the sustainability impact on providing NMT facilities, for a future scenario, inside the CBD of Bangalore and around the bus stops carrying trips to the CBD. Three case studies are presented with the first one considering only intra zonal (CBD) trips, the second one considering only inter zonal trips having CBD as destination, and the third one considering both above mentioned the trips. The results of all the three case studies found an increase in the CSI (0.002 for the first case study, 0.076 for the second case study, and 0.100 for the third case study) for the peak-hour trips inside the CBD, on providing NMT infrastructures. This increase showed an improvement in the sustainability. Further, for the case study 1, which consisted of high percentage of short distance trips, the major beneficiaries of the NMT infrastructures were the low-income group. There was a reduction in public transport trips, of which the main contributors were the low-income group, from 142706.2 to 96410.2.

Assessing Transportation Equity Considering Individual Travel Demand and The Feasibility Of Trip Mode Alternatives

Utkuhan Genc (12477645) 29 April 2022 (has links)
<p>  </p> <p>Transportation access is an important indicator of the quality of life and if it is inequitable, it will limit the work, leisure, and other essential opportunities for people and worsen the access for the disadvantaged groups. In the U.S., increased auto-dependency and the lack of other feasible alternative transportation modes exacerbate the negative impacts of this inequity, especially for the people without automobiles. The transportation equity in terms of the number of feasible transportation mode alternatives to serve a trip (i.e. mobility option equity) has not been extensively evaluated in the literature. Existing studies mainly analyzed the access to transportation infrastructures (e.g., bus stops, bike lanes, shared bike stations) based on the proximity at the zonal level. However, having access to a certain trip mode based on proximity does not necessarily add to the mobility option equity. First, mismatch may exist between the infrastructure and an individual’s travel demand. For example, if someone lives closely to a bus station but the bus route that can be accessed does not align with this person’s trip destination, they will not be able to use bus as a feasible mode for this trip. Second, existing accessibility-based studies often lack consideration of the trip feasibility (in terms of cost, quality, and safety) of using transportation infrastructures at the route level. For example, if a walking trip route is generated without considering the existence of sidewalks, the individual might have to walk on a unsafe busy road. In this case they will not be able to walk to satisfy their travel demand. Therefore, better transportation equity metrics concerning the feasibility of using transportation infrastructures to serve individuals’ travel demands are needed. </p> <p>To address this gap, this thesis defined the “travel-demand-relevant access” (mobility-need-relevant access) metric to evaluate transportation access in the context of individual travel demands and route-level infrastructure constraints and developed a framework to use GPS data to quantify the proposed metric for transportation equity analysis. Assessing which transportation modes are feasible alternatives to serve a trip, requires trip-level disaggregated travel demand data and detailed transportation infrastructure information. The recent development of information and communication technologies and open data efforts provide unprecedented opportunities for such trip-level analysis. With these developments it is now possible to evaluate the feasibility of a mode both the cost- and quality-based measures. The cost-based method estimates the monetary and time cost of using each mobility option and compares it with prominent trip mode (car) to examine “forced car use” concerning the travel demand. The quality-based method comprises accessibility and mobility-based performance measures to evaluate the feasibility of a certain trip mode regarding the ease of use and safety with relation to the infrastructure characteristics. The mobility options/alternatives deemed feasible with these two methods were used in the equity analysis, where the travel-demand-relevant access on the spatial and sociodemographic level was evaluated. </p> <p>The proposed framework was applied to the Indianapolis Metropolitan Planning Area (MPA) as a case study. The key insights of this study can be listed as (1) it is important to consider travel-demand-relevant access to evaluate transportation equity because we found that 40% of the trips that were identified as accessible by public transit are not feasible when travel-demand-relevant access is considered; (2) suburban areas on average have 12% less mobility options available compared with  the urban core which forces high car ownership in these areas; amd (3) people with non-college educational attainment, households with more crowded rooms, and larger families are the negatively impacted disadvantaged groups while census block groups with high composition of white middle-class suburban families have the lowest number of options (1.5 on average) available. </p> <p>The suburban populations with a low number of mobility options (with a vehicle) are not necessarily at a disadvantage in terms of mobility option equity, since suburban areas are by design made to be car dependent. However, the lower number of feasible mobility options in these areas possesses a risk for the future if the consequences are not evaluated carefully. In terms of urban migration, if out-migration from the urban core to suburban areas keeps increasing as the pandemic trend suggests, the forced car ownership in suburban areas could increase and create/worsen transport deserts. This increase in vehicle ownership contradicts equity and environmental goals regarding transportation. If we observe an increase in the suburban to urban core migration trend, it can force disadvantaged groups to move into suburban areas because of gentrification and increasing prices. These disadvantaged groups could suffer from the limited amount of mobility options in suburban areas, since their access to opportunities would decrease. </p>

Achieving a Collaborative Goal-oriented Planning Process : Exploring the Early Stages of Swedish National Transport Planning / Att uppnå en kollaborativ målfokuserad planeringsprocess : Undersökning utifrån de tidiga skedena av Sveriges nationella transportplanering

Wallgren, Signe Hanson January 2022 (has links)
The transport sector is facing a noticeable challenge to decrease its environmental and climate impacts, as well as to increase the possibility to achieve the objectives that are managing the societal development. Additionally, the early stages of transport planning are characterised by the participation of many stakeholders and that several areas of interest are affected, which entails that no distinct solution exist. This is an example of a wicked problem. One strategy there has been found efficient to handle wicked problems is the collaborative planning approach. In Sweden, the Strategic Choice of Measures approach (SCM) is used in the early stages of the transport planning process to enable the integration of several perspectives and discussion of alternative measures. Previous studies show that there is a need for increased consideration of environmental aspects and use of the collaborative methodology in SCMs. Furthermore, there should be an increased coordination between the actors and inclusion of a broader problem description in the early stages of transport planning to be able to achieve the Swedish climate objective.  This degree project aimed to explore the early stages of national transport planning in Sweden in relation to the potential of achieving the objectives managing the transport system, with a focus on the environmental aspects and objectives. A qualitative methodology was used, based on a literature review, case study, semi-structured interviews with representatives from four governmental authorities, as well as a content analysis based on concepts from theories on collaborative planning and management by objectives.  The study found that the interviewees, in general, had a common understanding of the early stages of national transport planning in Sweden. The differing point of view that existed were dependent on the governmental authority’s role and possibility to participate in these planning steps. The biggest differences were found to be the opinion of what role the SCM should have in the transport planning and how environmental aspects should be considered. Further, the result and analysis showed that the early stages mean great opportunities for the contribution of achieving the environmental objectives, since the process of setting objectives is based on comprehensive objectives and a broad problem description, as well as the possibility to consider environmental aspects throughout the early stages. The result and analysis of the study also showed that potential of the early stages to consider environmental aspects and contribute to the achievement of environmental objectives would benefit from some improvements. The suggested improvements are to include support for increased transparency, develop new tools for assessment of measures and break down comprehensive objectives to the relevant planning level. Lastly, the study showed that the process pf setting achievement-inducing objectives and the collaborative planning approach may benefit from being used together. This conclusion would most likely be possible to apply to other societal development sectors when setting objectives. / Transportsektorn står inför en märkbar utmaning för att minska sin miljö- och klimatpåverkan, samt möjligheten att bidra till att uppnå de mål som styr samhällsutvecklingen. Dessutom karaktäriseras speciellt de tidiga skedena av transportplanering av att flera olika aktörer medverkar och att flera intressen påverkas, vilket medför att ingen entydig lösning finns. Detta är ett exempel på ett komplext problem (eng. wicked problem). För att hantera dessa problem har den kollaborativa planeringsteorin identifierats som en effektiv strategi. I Sverige används åtgärdsvalsstudien (ÅVS) i de tidiga skedena av transportplaneringsprocessen för att möjliggöra integrering av flera perspektiv och diskussion av alternativa åtgärder. Tidigare studier visar att det inom åtgärdsvalsstudier krävs en ökad hänsyn till miljöaspekter samt att den kollaborativa metodiken inte används fullt ut. Vidare bör det inom de tidiga skedena av transportplaneringen ske en ökad samordning av aktörer och inkluderas en bredare problembild för att nå Sveriges klimatmål.  Detta examensarbete syftade till att undersöka de tidiga skedena av nationell transportplanering i Sverige kopplat till dess potential att uppnå målen som styr transportsystemet, med fokus på miljöaspekter och miljömål. Studien följde en kvalitativ metodik som inkluderade en litteraturstudie, fallstudie, semistrukturerade intervjuer med representanter från fyra statliga myndigheter, samt en innehållsanalys baserad på begrepp från teori inom kollaborativ planering och målstyrning.  Studiens resultat visade att det generellt finns en samstämmig syn mellan intervjupersonerna för hur de tidiga skedena av Sveriges nationella transportplanering ser ut. Skillnaderna i synsätt som fanns grundade sig i myndighetens roll och möjlighet att delta i dessa planeringssteg. De största skillnaderna visade sig vara synen på vad åtgärdsvalsstudien ska ha för roll i transportplaneringen och på vilket sätt miljöaspekter bör tas hänsyn till i tidiga skeden. Vidare visade resultatet och analysen att de tidiga skedena har stora möjligheter att bidra till att miljömålen uppnås, detta genom att processen att sätta mål utgår från övergripande mål och en bred problembild, samt att miljöaspekter kan tas hänsyn till i alla steg inom de tidiga skedena. Studiens resultat och analys visade också att de tidiga skedenas potential att ta hänsyn till miljöaspekter och bidra till att miljömål uppnås skulle gynnas av vissa förbättringar, så som stöd för ökad transparens, att utveckla nya verktyg för bedömning av åtgärder och att bryta ned övergripande mål till den relevanta planeringsnivån. Avslutningsvis visade studien att processen att sätta rationella mål och den kollaborativa planeringsapproachen kan gynnas av att användas tillsammans. Denna slutsats skulle troligtvis även kunna appliceras inom andra samhällssektorer.
