Travelling Distances,Modal Split and Transportation Energy in Thirty Residential Areas in Oslo

A study of the use of car and public transport among residents in 30 residential areas in Greater Oslo indicates that urban planning variables have a significant influence on the energy use per capita for local transport. Residents in local communities with a high density and a short distance to downtown Oslo travel considerably shorter distances and use considerably less energy per capita than those who live in low-density, outer areas. This is true also when the effects of other variables are neutralized. The influence of urban planning variables on the modal split is lower than on energy use. The distribution between public and private transport is influenced most of all by car ownership.     

Hyperautomobility and Governmentality in Auckland

Abstract

A number of cities around the world are associated with very high levels of private motor car usage, and Auckland provides an example of one of these ‘hyperautomobile’ cities. There are many problems with this system of transportation and dependence on the private car, including environmental, social and city design dimensions. Though there is a clear aspiration to move towards reduced levels of car usage in the city's transport and spatial planning strategies, there are major difficulties in implementation terms. We develop and consider future scenarios to 2041 to reduce these levels of motorization, and subsequent transport CO₂ emissions, with a much greater use of public transport, walking and cycling, urban planning, and low emission vehicles. The current implementability of such a ‘sustainable mobility’ future is however questioned in the current political and social context, and critically debated in terms of the available governance mechanisms and the limited attempts to shape the behaviour of the public. We conclude by calling for a reconsideration of the policy measures being considered, including the range and levels of application and investment; with a much wider framing of the transport planning remit, and carried out within a much stronger participatory framework for decision-making.     

The sustainability of a car dependent settlement pattern: an evaluation of new rural settlement in Ireland

The paper reports the findings of a small scale study comparing the personal travel patterns of households of similar type, living in a rural area and a small urban area of the Dublin city region. The study found that the rural area was less environmentally sustainable as a result of the extent of its dependency on the motor car, an inefficient and polluting transport mode. The study also provided evidence that the quality of life in the rural area was adversely affected by aspects of car dependency. There appeared to be a higher risk of traffic accident, rural dwellers used less healthy forms of transport, they suffered restricted mobility and, as a consequence enjoyed a less varied social life than their urban counterparts.     

User Perceptions and Attitudes on Sustainable Urban Transport among Young Adults: Findings from Copenhagen,Budapest and Karlsruhe

Abstract

This paper addresses the relevance of the demand side for the achievement of sustainable transport in urban areas. The underlying thesis is that a better understanding of user habits, perceptions and attitudes with its specific dynamics is essential for a successful design of targeted transport policies. In line with this, the paper at hand is based on research that aims at improving the knowledge of urban-transport-related habits and attitudes of young adults. The results of three interview meetings that were held in Karlsruhe, Budapest, and Copenhagen with participants aged between 20 and 30 are presented. Background of the interviews is a range of studies that indicate that young people in urban areas seem to be less interested in cars than the generation before. And indeed, the interview meetings reveal that participants had a rather pragmatic attitude towards transport modes. They wished a transport system that is flexible, convenient and cheap. Despite many differences, most participants showed rather positive attitudes towards policies supporting alternatives to car-based transport. However, it will be crucial for policy shaping to what extent the observed behaviour patterns and attitudes will persist over time.     

Two ways of defining sustainable mobility: Autolib’ and BeMobility

Abstract

European cities have emerged as laboratories for ‘sustainable mobility'. In the last few years, they have supported numerous electric car projects which combine clean engine technologies with offers on public or shared mobility. This paper compares two ongoing public electric car services in Berlin (BeMobility) and Paris (Autolib’). We explain how both projects shape future visions of sustainable mobility and transform regional transport systems in specific ways through their performative impact as local transport policy tools. Focusing on the socio-economic and political processes through which both projects were conceived and put into practice, we explain their differences as they reflect participating actors' interests in a French versus German industrial and transport policy context after the economic crisis in 2008. We find that whereas BeMobility integrates electric cars as one element in Berlin's intermodal transport system, and thus is centred around ‘intermodality' as the central vision of sustainable transport, Autolib’ in Paris essentially reproduces the dominant mode of private passenger car transport through adding a shared electric car fleet.     

Wider roads, more cars

The transport policy currently followed in many European cities seems to be a combination of investments in public transport in order to increase, or at least maintain, its market share, and road building in order to keep up with expected traffic growth. Apparently, there is a prevalent belief among policy makers that increased road capacity in urban areas does not in itself cause any growth in car traffic worth mentioning. Such a belief neglects the simple economic theory of supply and demand, as well as more specific theories about the dynamics of traffic under congested conditions. An empirical study of commuting patterns in two transport corridors in Oslo, Norway, shows that a considerable proportion of commuters are sensitive to changes in the speed of the respective modes of transportation. The mode chosen depends to a large extent on the ratio of door-to-door travel times by car and transit. Freer flowing traffic in the road network will induce a higher proportion of commuters to travel by car. Conversely, faster public transport will reduce the proportion of car commuters, but the effects of such improvements will be offset if road capacity is simultaneously increased. In addition to the relative speeds of car and transit, the parking conditions at the workplace are of great importance to the choice of transport mode.     

Local Transport Problems and Possible Solutions: Comparing perceptions of residents,elected members,officers and organisations

It is generally accepted that the current growth in personal car use poses a serious threat to local communities and the environment, and that radical changes in transport policy are needed. In order for local authorities to develop acceptable sustainable transport options, it will be necessary that they have a clear view of the attitudes and perceptions of various groups in their community. This research compared the views of elected members and officers with those of residents and organisations in relation to the local transport situation and the use of car travel reduction measures. It was found that the views of elected members and officers reflect those of residents rather well. The views of local organisations, however, were different. Organisations were, in particular, more negative about policy measures that aim to reduce car use in the town centre. They also attached more importance to the viability of the local economy than the other respondents. However, they did agree with the other groups that the quality of life in the community would improve if there was less traffic. The consequences of these findings for local transport planning are discussed.     

Activity-Based Patterns of Everyday Mobility: The Potential for Long-Term Behaviour Change Across Five Groups of Travellers

Abstract

Significant differences in our mobility patterns can be found in relation to both range/distance and form. While some people travel on multiple occasions to global destinations over the course of a year, others travel mainly locally, that is, by bicycle or on foot. Policymakers and planners need to have a clear conception of the different mobility patterns if they are to develop valid and precise measures promoting more sustainable forms of mobility. This paper points to five key mobility types based on an exploratory cluster analysis of approximately 20,000 Norwegian travel diaries. Three of the defined groups are dominated by the private car, while two are oriented towards the use of public transport, bicycling and walking. The key differences and similarities between the mobility types are discussed and the relationship between everyday travel patterns and long-distance travel is analysed. Opportunities and challenges for transformations in the everyday travel habits of the five groups are discussed in the final section.     

Evaluating an Employer Transport Plan: Effects on travel behaviour of parking charges and associated measures introduced at the University of Sheffield

Journeys to work form a significant proportion of all car journeys and employer transport plans have been advocated as a way to manage the transport needs of workers in order to contain the level of car trips and, therefore, emissions and other negative effects. A questionnaire survey and focus group interviews were used to evaluate the success of an employer transport plan implemented by the University of Sheffield in September 1997. The policy was associated with a marginal (7%) reduction in car use and promoted a limited increase in travel diversity. An objection to the principle of paying to park at work and ineligibility for a permit both deterred car use. The policy caused a re-evaluation of the journey to work. Nevertheless, a number of factors worked against switches in behaviour, particularly employees' perceptions of the university's motivation for introducing the plan and attitudes towards car use and public transport. Disincentives to car use need to be much more significant to persuade more employees to leave their car at home, and need to be tied to substantial improvements in the availability of non-car alternatives.     

Exploring the relationship between residential segregation and thermal inequity in 20 U.S. cities

A combination of the urban heat island effect and a rising temperature baseline resulting from global climate change inequitably impacts socially vulnerable populations residing in urban areas. This article examines racial/ethnic and socioeconomic inequities in the spatial distribution of exposure to urban heat in the context of climate justice and residential segregation in the U.S. An urban heat risk index (UHRI) is calculated from measures of land surface temperature, structural density, and vegetation abundance, acquired from summer 2010 remote sensing imagery. Twenty of the largest metropolitan statistical areas (MSAs) in the U.S. are selected and analysed using census tract-level socio-demographic data from the U.S. Census. Multilevel modelling is utilised to examine the statistical associations between urban heat, minority status, socioeconomic disadvantage, and MSA-level segregation of racial/ethnic minority groups. Variables representing socioeconomic status (i.e. household income, home ownership, and education level) are consistently and significantly associated with greater urban heat exposure. Minority status and measures of segregation have a significant but varied relationship with urban heat exposure, indicating that there are inconsistent associations with urban heat due to differing social geographies. Urban heat and social vulnerability present a varying landscape of thermal inequity in different metropolitan areas, associated in many cases with residential segregation.     

Latin American busways: moving people rather than cars

The rapid growth of Latin American urban centres beginning in the 1970s placed a heavy strain upon urban transport service providers. Facing high population growth from a citizenry dependent upon public transport and having limited financial resources to develop car‐based infrastructure, Latin American municipal planners were challenged to create a new transport paradigm. One ingenious response to this dilemma was the busway, a surface metro system that utilizes exclusive right‐of‐way bus lanes. The developers of the Latin American busways astutely observed that the ultimate objective was to swiftly, efficiently and cost‐effectively move people rather than cars. Examples of innovative busway systems are presented from Curitiba, Bogota, Porto Alegre, Quito and Sao Paulo. The low cost, flexibility and speed of the exclusive busways all contribute to extremely high levels of customer satisfaction. Innovative approaches to the design of busway loading stations and simplified ticketing have also helped to reduce operating costs and improve customer flows. Additionally, clear system maps, colour‐coded routing, system safety and cleanliness and superior customer service have helped direct consumer preference towards the busway. The success of busways has also proved that costly subway systems or uncontrolled sprawl are not the only options available to municipal planners. The Latin American busway corridors provide high peak capacities that permit busway corridors to serve the transit requirements of most medium‐ to large‐sized cities. When integrated with progressive land‐use policies, busways can also form the basis of more sustainable urban design by encouraging development corridors with high‐density, mixed‐use land use. The environmental benefits and calming influences afforded cities by busway systems have translated into dramatically improved levels of quality of life indicators, including improvements in health, crime reduction and poverty alleviation. The user‐friendliness and cost‐effectiveness of busway systems have convinced municipal leaders in North America, Europe and Australia to develop similar systems of their own. Latin American busways thus provide a unique example of South to North technology transfer.     

Can the commons be temporary? The role of transitional commoning in post-quake Christchurch

ABSTRACT

In recent work on commons and commoning, scholars have argued that we might delink the practice of commoning from property ownership, while paying attention to modes of governance that enable long-term commons to emerge and be sustained. Yet commoning can also occur as a temporary practice, in between and around other forms of use. In this article we reflect on the transitional commoning practices and projects enabled by the Christchurch post-earthquake organisation Life in Vacant Spaces, which emerged to connect and mediate between landowners of vacant inner city demolition sites and temporary creative or entrepreneurial users. While these commons are often framed as transitional or temporary, we argue they have ongoing reverberations changing how people and local government in Christchurch approach common use. Using the cases of the physical space of the Victoria Street site “The Commons” and the virtual space of the Life in Vacant Spaces website, we show how temporary commoning projects can create and sustain the conditions of possibility required for nurturing commoner subjectivities. Thus despite their impermanence, temporary commoning projects provide a useful counter to more dominant forms of urban development and planning premised on property ownership and “permanent” timeframes, in that just as the physical space of the city being opened to commoning possibilities, so too are the expectations and dispositions of the city’s inhabitants, planners, and developers.     

Characteristics of Urban Natural Areas Influencing Winter Bird Use in Southern Ontario,Canada

Characteristics of urban natural areas and surrounding landscapes were identified that best explain winter bird use for 28 urban natural areas in southern Ontario, Canada. The research confirms for winter birds the importance of area (size) and natural vegetation, rather than managed, horticultural parkland, within urban natural areas as well as percent urban land use and natural habitat in surrounding landscapes. Alien bird density and percent ground feeding species increased with percent surrounding urban land use. Higher percent forest cover was associated with higher percentages of forest, bark feeding, small (<20 g) and insectivorous species. Natural area size (ha) was related to higher species richness, lower evenness and higher percentages of insectivorous, forest interior, area-sensitive, upper canopy, bark feeding, and non-resident species. Higher number of habitat types within natural areas and percent natural habitat in surrounding landscapes were also associated with higher species richness. Common, resident bird species dominated small areas (<6.5 ha), while less common non-residents increased with area, indicative of a nested distribution. Areas at least 6.5 ha and more generally >20 ha start to support some area-sensitive species. Areas similar to rural forests had >25% insectivores, >25% forest interior species, >25% small species, and <5% alien species. Indicator species separated urban natural areas from rural habitats and ordination placed urban natural areas along a gradient between urban development and undisturbed, rural forests. More attention is needed on issues of winter bird conservation in urban landscapes.     

Counteracting the focusing illusion: Effects of defocusing on car users’ predicted satisfaction with public transport

Car users underestimate their potential satisfaction with public transport due to a focusing illusion (i.e., focusing on a too narrow range of aspects related to the focal event). To investigate whether a defocusing technique would increase car users’ predicted satisfaction with public transport, the effects of defocusing techniques, generic (Study 1) and self-relevant (Study 2), were investigated. In Study 1 (estimate daily time spent on ten pre-selected activities), the generic defocusing technique did not generate higher predicted satisfaction with public transport. In Study 2, the self-relevant defocusing technique generated higher predicted satisfaction on quality attributes, namely satisfaction with the number of departures, the number of available seats and the condition of the vehicles, in comparison with controls. It is concluded that the self-relevant defocusing technique applied in Study 2 (state your various everyday activities and describe how much time you engage in them) was successful in making car users take into account activities in life that will remain unchanged if they were to use public transport for their daily travel. Additionally, in Studies 1 and 2, it was found that car-use habit, regardless of the experimental condition, influenced the magnitude of predicted satisfaction, that is, the higher the car-use habit, the lower the predicted satisfaction with public transport.     

Bike Networking in Rio: The challenges for non-motorised transport in an automobile-dominated government culture

Rio de Janeiro has developed, since 1992, an 84 km cycling network, more as the outcome of green and NGO lobbying than of clear cut and continuous government choices. The city transport policies are widely dominated by car and bus oriented priorities with insufficient investment in rail, ferryboat and other mass transport options. Bicycle use is potentially part of a new policy aimed at reducing automobile dependence and its social and environmental consequences. The Rio experience was influenced by the Dutch example, especially the Amsterdam achievements. The process of building this cycling infrastructure is also a political and cultural one, sometimes encountering tough resistance from some sectors of the city government and the public, hostile to an investment they consider futile. However, opinion polls conducted in Rio have shown impressive support for bike networking. The main conditions for success are: good integration, maintenance and security; appropriate support infrastructure; and continuity with regular investments and upgrading.     

The acceptability, personal outcome expectations, and expected effects of transport pricing policies

Acceptability and personal outcome expectations (i.e., the extent to which one expects to be better or worse off) of transport pricing policies were examined in relation to the expected effects of these policies on one’s own car use, congestion and environmental problems. Car users who commuted frequently by car and experienced congestion on a regular basis evaluated two pricing measures, which were mainly aimed at either decreasing congestion (by tolling at congested areas) or environmental problems (by a differential kilometre charge based on car mass). For the policy mainly aimed to reduce congestion, acceptability was higher and personal outcome expectations were more positive when respondents expected reductions in congestion when the policy was implemented. The policy aimed to reduce environmental problems was more acceptable and respondents expected to be better off in general when they expected reductions in environmental problems after its implementation. Expectations, both about a decrease in congestion and environmental problems were related to respondents’ personal outcome expectations of the policy mainly aimed to decrease environmental problems. We conclude that the acceptability of transport pricing policies are not necessarily low because car users expect negative effects on their car use, but rather because they are not be convinced that transport pricing policies will reduce congestion and environmental problems.     

Local Residents Perception of Benefits and Losses From Protected Areas in India and Nepal

High densities of people living around protected areas (PAs) in South Asia require management strategies to balance conservation goals and livelihood needs. Based on a survey of 777 households around five PAs in India and Nepal, this paper provides a comparative perspective of Indian and Nepali households’ views of protected area benefits and costs, their attitude toward conservation in general, and attitude toward protected area staff. Results indicate mixed responses towards tourism, varying from very favorable in Nepal to less favorable in India. The majority (81%) held positive attitudes towards the existence and importance of PAs but had negative perceptions of PA staff (69%). Most residents perceived benefits from access to fuel wood, fodder and other PA resources including benefits from tourism, while crop and livestock losses from wildlife were the main costs. Households overall positive attitudes towards the PAs and conservation despite high losses from living around PAs suggests that local residents may support conservation if their livelihood needs are met. Comparisons of household attitudes and perceptions suggest that locally based strategies rather than top-down approaches are likely to be more effective. Extending PA benefits to smaller landholders, households that are highly resource-dependent or experiencing higher income losses from human-wildlife conflicts, and less educated residents are particularly important to balance costs and losses from living around protected areas.     

Urban Domestic Gardens (XIV): The Characteristics of Gardens in Five Cities

Domestic gardens make substantial contributions to the provision of green space in urban areas. However, the ecological functions provided by such gardens depend critically on their configuration and composition. Here, we present the first detailed analysis of variation in the composition of urban gardens, in relation to housing characteristics and the nature of the surrounding landscape, across different cities in the United Kingdom. In all five cities studied (Belfast, Cardiff, Edinburgh, Leicester, and Oxford), garden size had an overwhelming influence on garden composition. Larger gardens supported more of the land-use types recorded, in greater extents, and were more likely to contain particular features, including tall trees and mature shrubs, areas of unmown grass and uncultivated land, vegetable patches, ponds, and composting sites. The proportional contribution of non-vegetated land-uses decreased as garden area increased. House age was less significant in determining the land-use within gardens, although older houses, which were more likely to be found further from the urban edge of the city, contained fewer hedges and greater areas of vegetation canopy >2 m in height. Current UK government planning recommendations will ultimately reduce the area of individual gardens and are thus predicted to result in fewer tall trees and, in particular, less vegetation canopy >2 m. This might be detrimental from ecological, aesthetic, social, and economic stand points.     

Integrating urban ecosystem sustainability assessment into policy-making: insights from the Gold Coast City

This paper introduces a policy-making support tool called ‘Micro-level Urban-ecosystem Sustainability IndeX (MUSIX)’. The index serves as a sustainability assessment model that monitors six aspects of urban ecosystems – hydrology, ecology, pollution, location, design, and efficiency – based on parcel-scale indicators. This index is applied in a case study investigation in the Gold Coast City, Queensland, Australia. The outcomes reveal that there are major environmental problems caused by increased impervious surfaces from growing urban development in the study area. The findings suggest that increased impervious surfaces are linked to increased surface runoff, car dependency, transport-related pollution, poor public transport accessibility, and unsustainable built environment. This paper presents how the MUSIX outputs can be used to guide policy-making through the evaluation of existing policies.
