Policy Scenarios

Urban activities, such as transportation, are responsible for a large portion of energy-related CO2 emissions. As the need for sustainable urban development increases, decision-makers embrace Life Cycle Assessment (LCA) as a reliable tool capable of generating scientifically based information on environmental impacts. However, there is still a lack of an analysis standard regarding the particularities of urban systems. Therefore, this research aims to define current and future environmental profiles, considering a case study of the public transport system in Porto Alegre, considering specificities of the urban context and different public policy scenarios through LCA. These results show that, although the transportation system management relies on the municipalities, the higher significance of environmental impacts depend on a national policy for using biodiesel in the diesel sold, which could lead to an increase of, for example, up to 9.4% of CO2 emissions from 2017 (baseline) to 2030. Finally, it is perceivable that to conduct a LCA to support decision-making in public urban services, a detailed approach is needed considering that technological variables interact with the territorial context and policy changes.

Public Transportation System

The spatial and economic growth of cities and regions is heavily influenced by transportation. A better knowledge of public transportation will help to clarify the positions of the public and private sectors, as well as recognize the critical government position. To study the problems and issues of the public transportation system, Qasimabad, Hyderabad is selected as a study area due to some serious issues of public transportation. Personal observations and questionnaires were used to gather data from the research area. And for analyzing the data SPSS and MS Excel are used. The results reveal that the existing public transportation system is not meeting the needs of residents. Hence use of private transportation is high and causing environmental and traffic jam problems. As 68% of respondents use a motorbike for recreational purposes, 64% of respondents are not using public transport due to safety factors. In general, 54% of respondents were not satisfied with the service of public transport. As people are willing to use public transport but due to some factors such as safety, they are not using public transport so it is suggested that both vehicles and roads must be safe for users. This study aims to study the existing scenario of public transportation in terms of services and facilities, and people’s perception about public transportation. So it is concluded that people are tending to use public transport but under some certain conditions (factors preventing the use of public transport), if these concerns are solved then public transport system will become more efficient.

Static Approach

The city of Curitiba, located at Southern Brazil, is recognized by its urban planning structured on three pillars: land use, collective transportation, and traffic. With 3.8 million people in its metropolitan area, the public transport system deals with approximately 2.5 million passengers daily. The structure and properties of such a transportation system have substantial implications for the urban planning and public politics for sustainable development of Curitiba. Therefore, this paper analyzes the structure of the public transportation system of Curitiba through the theory of complex networks in a static approach of network topology and presents a comparative analysis of the results from Curitiba, three cities from China (Shanghai, Beijing, and Guangzhou), and three cities from Poland (GOP, Warszawa, and Łódź). The transportation network was modeled as a complex network with exact geographical coordinates of its bus stops. In all bus lines, the method used was the P-Space. The results show that this bus network has characteristics of both small-world and scale-free networks.

The Government

The American transportation system is large, pervasive, decentralized, and an enormously important part of the economy. The public demands that it be efficient, available, reliable, and safe, and expects the government to ensure that these demands are met. For more than two decades we have also sought to reduce its highway dominance, reduce its consumption of energy, and reduce its negative environmental impacts. The fact that many of these efforts have failed raises the question of why the system seems so resistant to policy intervention. Americans believe that industry, including transportation, should be left to the private sector, subject to market principles, and competitive economics. Despite this, transportation has some special characteristics that have resulted in government's ownership of most of the fixed infrastructure, while the manufacture, ownership, and operation of vehicles (the big expense) are left in private hands. Government charges the private sector for the use of its facilities to maximize productivity and deal fairly with users. But determining these charges is complex and is necessarily the product of philosophy as well as sophisticated costing. It is the source of endless squabbling between modes and special interests. This tension-combined with the huge size of the system, the dominance of the private sector, its decentralization, and other factors-makes government intervention into the system on behalf of societal goals often challenging and sometimes unsuccessful.

The municipality of Marituba, Metropolitan Region of Belém - RMB, has suffered environmental impacts due to irregularities in the landfill operation implemented in 2015, which triggered social impacts perceived by all the population, including neighboring municipalities, such as Ananindeua and Belém Protests were carried out by the Movement Outside the Garbage that is constituted by the dwellings of the surrounding neighborhoods to the place where the embankment is located, of owners of commercial activities linked to the tourism and Non Governmental Organizations that interrupted several times the transit of the main route that interconnects the seven municipalities of the RMB and the entrance of the embankment, in order to draw the attention of the municipal public power to the problems that the population would have been facing ever since. From this, the following questions arose: What social impacts would people be making in these protests? Would such problems be directly related to the activities carried out in the landfill? And finally, what are the actions of the public authority and the company that manages the enterprise in the management of these social impacts? The relevance of this study concerns not only the identification of social impacts considering the fragility of this approach in the Environmental Impact Studies and concomitantly in the Reports of Environmental Impacts, but also, from the point of view of the debate about the licensing process of enterprises of this nature and employment and the need for the joint use of environmental and urban policy instruments, considering that RMB municipalities have not yet used sustainable alternatives for the reduction of solid waste produced in their territories, as well as the reduction of environmental impacts caused by dumps , and in the case of Marituba, of the landfill that operates outside the standards established by the Brazilian Association of Technical Standards - ABNT, which is responsible for the management and treatment of solid waste and the National Policy on Solid Waste - PNRSN.

Green space is essential for the implementation of the idea of sustainable urban development. This paper contains original research on the implementation of local government tasks in the development of public green space. The aim of this research was to analyse the actions taken by the municipal authorities regarding the development of public green space, including the acquisition of real properties, the regulation of their legal status, as well as the adoption of planning and programme documents. The Polish Central Statistical Office data on the public green space of the largest cities in Poland were analysed in order to determine the dynamics of changes. Then, the focus was placed on Krakow, where the authors analysed in detail the distribution and type of urban green space as well as the actions taken by the Municipality to both extend it and to protect it against building development. The criterion of green space accessibility to city residents was indicated as a necessary aspect to be considered in the overall assessment of the existing greenery. The conclusions include the assessment of the actions of the Krakow authorities and the observed trends in the development of public green space.

Abstract Transportation influences health through its effects on people's access to goods, services, and life chance opportunities; social interactions; physical activity levels; air pollution exposures; and road injury risks. Given the ageing of populations, it is essential that decisions about land use and transportation systems are appropriate to meet the mobility needs of older people and support healthy ageing. Not all transportation options, however, may be accessible to older people. Factors that affect accessibility relate to the spatial and physical characteristics of places, personal and social contexts of individuals, and rules and norms underpinning planning and policy making. This research aimed to understand how different parts and processes of urban systems interact to influence transportation options for older people. Using the Greater Sydney area as a case, we drew on key informant interviews and public policy documents to identify the considerations that inform planning and policy making as they pertain to the nature of cities and the opportunities of older people to get out and about. We compared and integrated these findings with peer-reviewed literature of similar urban growth areas. Our analysis mapped the factors of the human-urban system that are central to enabling transportation mobility for older people, articulated their interrelationships, and identified the actors that influence them. Our results point to the involvement of actors from the public health, community development, transportation, and urban planning sectors at multiple levels of government. Each of these actors operate within their own remit to influence a part of the urban system relevant to older people's transportation, such as the zoning of land, the approval of housing developments, and the location of bus stops. However, these individual actions are constrained by others in the system. We interpret this complexity with a governance lens. Key messages Efforts to promote mobility in old age should move beyond ‘single solutions to single issues’ approaches toward those that reflect the complexity of cities and the ways that people move within them. For sustained realization of desired outcomes, age-friendly initiatives cannot occur in isolation, but rather must take into account the behaviours and dynamics of the urban system.

This paper shows the results of an in-depth techno-economic analysis of the public transport sector in a small to midsize city and its surrounding area. Public battery-electric and hydrogen fuel cell buses are comparatively evaluated by means of a total cost of ownership (TCO) model building on historical data and a projection of market prices. Additionally, a structural analysis of the public transport system of a specific city is performed, assessing best fitting bus lines for the use of electric or hydrogen busses, which is supported by a brief acceptance evaluation of the local citizens. The TCO results for electric buses show a strong cost decrease until the year 2030, reaching 23.5% lower TCOs compared to the conventional diesel bus. The optimal electric bus charging system will be the opportunity (pantograph) charging infrastructure. However, the opportunity charging method is applicable under the assumption that several buses share the same station and there is a “hotspot” where as many as possible bus lines converge. In the case of electric buses for the year 2020, the parameter which influenced the most on the TCO was the battery cost, opposite to the year 2030 in where the bus body cost and fuel cost parameters are the ones that dominate the TCO, due to the learning rate of the batteries. For H2 buses, finding a hotspot is not crucial because they have a similar range to the diesel ones as well as a similar refueling time. H2 buses until 2030 still have 15.4% higher TCO than the diesel bus system. Considering the benefits of a hypothetical scaling-up effect of hydrogen infrastructures in the region, the hydrogen cost could drop to 5 €/kg. In this case, the overall TCO of the hydrogen solution would drop to a slightly lower TCO than the diesel solution in 2030. Therefore, hydrogen buses can be competitive in small to midsize cities, even with limited routes. For hydrogen buses, the bus body and fuel cost make up a large part of the TCO. Reducing the fuel cost will be an important aspect to reduce the total TCO of the hydrogen bus.

Cultural heritage drives and enables sustainable urban development. The adaptive reuse of cultural heritage creates values while prolonging the lifespan of heritage. Similarly, circular economy creates value while extending the useful life of materials and elements through their reuse. Existing studies on adaptive reuse challenges seldom focus on cultural heritage properties, and they are often identified through the engagement of a limited variety of stakeholders, as compared to the actors normally involved in adaptive reuse. Filling this gap, this paper provides a preliminary baseline of challenges faced by the city of Amsterdam from the perspective of various involved stakeholders, and suggests solutions to address them. The participants represented the public, private, knowledge, and third sectors. The methods used were the following: for data collection, a multidisciplinary workshop using the steps of the Historic Urban Landscape approach as an assessment framework applied to multiple scales on adaptive reuse, and for data analysis, manifest content analysis. The results expanded the range of challenges and solutions reported by previous literature on the adaptive reuse of cultural heritage in content and scale by identifying 61 themes—e.g., knowledge and civic engagement. Tools and stakeholders were also identified. These findings provide a reference for future practice, policymaking, and decision-making, facilitating the adaptive reuse of cultural heritage to capitalize on its potential for sustainable development and circular economy.

As an extension of public space, the public transport system in modern society is an arena for cross-group interactions. Uncovering social segregation in public transport space is an essential step in shaping a socially sustainable transport system. Based on 2011 origin–destination flow data for London, we simulate the working flows between each pair of connected tube stations for every occupation with minimised transfer times and travelling hours and calculate the multi-occupation segregation index for all tube stations and segments. This segregation index captures the density and diversity aspects of the working population. The results demonstrate that segregation levels vary significantly across stations, lines, and segments. Transfer stations and tube segments in the city centre do not necessarily have lower levels of segregation. Those stations or segments close to a terminus can also be socially inclusive, e.g., Heathrow. Victoria is the line with the lowest levels of segregation, and Green Park is the most socially inclusive station during commuting peaks. The proposed mapping approach demonstrates the spatial complexity in the social performance of the public transport system and provides a tool for implementing relevant policy with improved precision.
