In many cities around the world, electric (e-)scooters have emerged as a new means of transportation. They are often advertised as supporting modal shift towards more sustainable transportation and as a tool for enabling more equity in mobility. However, the environmental impact depends on how they are used and what kinds of trips they replace. Integration of e-scooters into urban transport systems also implicates discussions on fair road space allocation. In our study, we assess the socio-economic profiles and usage patterns of e-scooter users in Vienna, Austria. We differentiate between two basic groups of e-scooter users (renters and owners) and apply two different methods. Firstly, based on an online survey, we examine the age, gender and education of e-scooter users and we look into which kinds of trips (commuting, shopping or leisure) and which other means of transportation are replaced by e-scooter trips. Secondly, we analyse data from field observations at cycle paths in Vienna in order to determine the share of e-scooter riders and their gender distribution. We find that e-scooter users are more likely to be young, male, highly educated and residents of Vienna. According to the survey, there are considerable differences in usage between owners of private scooters and users of sharing schemes. Whereas in both groups, e-scooter trips mostly replace walking and public transport as a mode, e-scooter owners also show a considerable mode-shift from private car trips. These results implicate that e-scooter riders are additional users of cycling infrastructure. This puts further pressure on the current allocation of road space, which provides little space for active modes of transport. We conclude that city policies should address this competitive relationship adequately by allocating more space to safe and convenient cycling infrastructure and traffic-calmed zones. This could not only help ease the current challenges due to e-scooters but also provide better conditions for walking and cycling and thereby at the same time contribute to a more sustainable and equitable urban transport system.  相似文献

Being on the move is part of children's everyday life in cities. However, little is known about how young children experience transport systems or their aspirations for mobility in cities. In this paper, we explore pre-schoolers' experiences with the mobile world and show their affinity with different transport modes and hopes for their current transport system. We draw on a participatory research project that engaged children in class discussions, a tile-based city building exercise and neighbourhood walks. Findings suggest that although the voices of children aged 3–5 years are absent in mobility or transport debates, children are fascinated by mobility and transport related activities and services. Pre-schoolers from Dunedin, New Zealand, though recognising a predominantly motorised transport system, also showed creative or alternative modes making their way into their own transport systems. In this paper we argue that children should be introduced to and experience alternative modes of transport in the early years to allow for more imaginary transport geographies creating greater support for more sustainable, liveable urban environments for all ages.  相似文献

While the legalisation of and policies around e-scooters remain the cause of much debate worldwide, this article sheds lights on e-scooter users’ current practices and their interactions with pedestrians in the city. Taking an ethnomethodological approach to public space and mobility, we use video recordings of e-scooter riders to show, firstly, how riders dismount and then move to acquire rights to continue moving, thereby ‘playing’ with traffic rules, in order to weave rapidly through congested urban environments. Secondly, we examine how e-scooter riders and pedestrians deal with the potentially unexpected appearance of e-scooters via displays of attention, adjustments of speed, and the relative rights and obligations established via category-relevant spaces. The findings offer insights into the integration of e-scooters as one of what may be many new forms of electric powered micro-mobility in urban space.  相似文献

ABSTRACT

Low-carbon mobility (LCM) features strongly in debates about the sustainability of cities and their resilience in the face of demographic, economic, and climate change. Transport is a major source of carbon emissions and there are indications that these continue to increase, despite the considerable recent advances in vehicle, engine, and fuel technologies. Reducing carbon emissions from transport may become more difficult, not easier. A particular issue relates to the New World cities, typified by those of North America and Australasia, which largely developed from the latter half of the nineteenth century onward and whose transportation systems were largely based around private vehicle ownership and usage. These cities are typically composed of low-density, dispersed suburbs, which are highly car dependent and resource and carbon emission intensive. This article develops a research agenda directed at determining and testing policy and planning measures relevant to the quest for low carbon mobility in New World cities. It suggests a rich agenda for essential research on LCM. Much of this agenda falls within the realm of the integration of transport and land use, with attention to urban design details to enhance the perceptions of and opportunities to use low carbon transport alternatives. Research topics identified for LCM research include (1) urban design and land use–transport integration (LUTI), (2) low carbon mobility policies directed at achieving widespread behavior change, (3) opportunities for new technology and its application, including requirements for systems and infrastructure, and (4) analysis and tools for informed decision making, including modeling, measurement, visualization, and especially assessment.  相似文献

Electric scooter (e-scooter) sharing systems (ESSs) have been widely adopted by many cities around the world and have attracted a growing number of users. Although some studies have explored the usage characteristics and effects of the built environment on ESS ridership using one city as an example, few studies have considered multiple cities to obtain generalizable and robust results. To fill this research gap, we collect the ESS trip data of five cities in the U.S., namely Austin, Minneapolis, Kansas City, Louisville, and Portland, and explore the effects of the built environment on ESS ridership after controlling for socioeconomic factors. The temporal distributions of e-scooter ridership of different cities are similar, having a single peak period on weekdays and weekends between 11:30 and 17:30. In terms of spatial distribution, the ESS ridership is higher in universities and urban centers compared to other areas. Multilevel negative binomial model results show that ESS trips are positively correlated with population density, employment density, intersection density, land use mixed entropy, and bus stop density in the census block group. E-scooter ridership is negatively correlated with the median age of the population in the census block group and distance to the city center. The findings in this article can help operators understand the factors that affect the ridership of shared e-scooters, determine the changes in ridership when the built environment changes, and identify high-ridership areas when ESS is implemented in new cities.  相似文献

The journey to work receives a great deal of research attention due to the peak demand on the transport system. Cities are increasingly concerned with managing traffic congestion and reducing pollution and most of the focus of this research has been on cars, public transport, walking and cycling. In contrast, the role of powered two-wheelers (PTWs), including motorcycles and scooters, in commuting has received little attention, particularly in the context of cities in the developed world. This paper provides new insight into commuting by PTW by drawing on census journey to work data from Australia's three largest cities (Sydney, Melbourne and Brisbane) combined with an intercept survey of PTW commuters in Melbourne. It explores the extent of, and changes in, PTW commuting as well as the demographics of PTW commuters. While PTWs account for only a small percentage of urban commuting in Australian cities, their use is growing rapidly and there is a concentration of commuting by PTW into city centres. PTW commuters tend to be high-income males in skilled professional and technical professions. The implication of these findings for transport policy are discussed.  相似文献

Shared e-scooters have become a common mode of transportation in many cities around the world. E-sooters provide convenient and quick rides for short distances and can act as a connection for first/last mile trips. To date, limited studies have explored the spatial variation of e-scooter trips and there is knowledge to be gained by investigating variables associated with e-scooter trip generation. This study implemented a spatial analysis approach, Geographical Weighted Regression (GWR), to explore how factors relating to demographics, density, diversity, design, urbanism scores, distance to transit and other transportation-related variables influence e-scooter trips in Louisville, KY. More than 400,000 e-scooter trips across 159 Traffic Analysis Zones (TAZs) were included in the study. Results show TAZ-level factors including land use, age distribution, gender distribution, Walk Score and Park Score impacted the density of e-scooters trips in the TAZ. The GWR model showed improvements over a global Ordinary Least Squares (OLS) model. Local goodness of fit ranged from 0.732–0.895 across the study area. This study can help governments and e-scooter sharing companies develop policies that maximize e-scooter use, equity, and accessibility while improving the mobility of cities.  相似文献

Urban growth has been increasing rapidly across the globe, in particular in low and middle-income developing countries. As city populations and GDP per capita rise exponentially, cities tend to experience similar challenges related to urban development and transport/mobility.One of the most problematic issues emerges when urban growth drives car-oriented urban development. This is characterised by a range of unsustainable patterns such as low-density development, urban sprawl, lack of plans and infrastructure to accommodate collective transport and active travel, and significant efforts and investments to meet the demand for private motorised vehicle use. For emergent cities, the risk is that these developments lead to highly inefficient, unhealthy and unsustainable urban systems that are difficult to remedy.This paper aims to identify recurrent governance and policy factors across sectors, as well as macro factors, that tend to contribute to car-dependent urban mobility systems in rapidly growing cities. It draws on qualitative and quantitative research findings from five under-researched Eastern European and Middle Eastern cities: Tallinn, Bucharest, Skopje, Adana and Amman. Data examining the evolution of urban mobility in these cities were collected as part of the Horizon2020 EU funded project CREATE.The paper investigates the extent to which car-dependent urban development processes can be avoided in rapidly growing cities, to support transitions towards liveable and sustainable cities. Finally, it provides policy recommendations targeting growing cities with low levels of car-use, in particular in Sub-Saharan Africa. It highlights the importance of acting swiftly to achieve targets such as the Sustainable Development Goals, the New Urban Agenda or the Paris Agreement, by supporting policies fostering efficient, sustainable and inclusive urban mobility and land-use across sectors and levels of governance.  相似文献

The growth of private motorised urban mobility has become a key issue in relation to environmental quality in China’s cities. This paper reports on a nationwide study of the changes in car use in the 2000s, conducted in eleven large cities. This may assist us in filling the gaps in our existing knowledge, which is based on individual city cases. It is apparent that China’s large cities are embracing a new era of the automobile at an unexpected speed and scale. However, at the same time, it seems that a ‘peak’ in car use has occurred in Shanghai and Beijing, as either the absolute number of VKT per capita has dropped or its growth has slowed in these cities. The changes in urban mobility are deeply affected by social and economic transition factors. The paper provides an in-depth analysis of the effects of increasing incomes and the growing middle class, changing lifestyles and the emerging consumer society, the appearance of the e-Society and an increasingly ageing society. In particular, the growing demand for car use by the younger generation (G2), women and elderly people for the purpose of social activity has become an important force behind the increase in overall VKT. The paper concludes with a discussion of current theoretical perspectives and the issues which should be addressed in future research on the social aspects of private motorised urban mobility in China.  相似文献

Key research themes on ICT and sustainable urban mobility   总被引:1,自引:0,他引:1  
Abstract

Information and communication technologies (ICTs) are hypothesized to replace or change the use of the transport system by facilitating new or different activities. This article offers a review of more than 40 years of research regarding the relationship between ICTs and urban mobility. We discuss the expectations for the changes in travel demand, travel patterns, and the urban form as a result of the development and introduction of ICTs. Much of the interest in the relationships between ICTs and mobility is premised on the expectation of substitution effects, but empirical findings often suggest more complex effects than direct substitution. Although research on single types of travel activity may sometimes indicate simple substitution effects, examination of the broader impacts may also reveal travel generation effects as well. As such, ICTs do not simply substitute mobility patterns but change them. A growing body of research focuses on changing mobility patterns (in terms of time and space), changes in the experience of travel and changes in the perceptions of travel costs due to the interaction between old and new technologies for overcoming distance. ICTs are gradually becoming embedded within the transport system, enabling flexibility, multitasking, and an increase in human activities.  相似文献

The work by Newman, Kenworthy and colleagues on the link between land use, transportation systems and travel patterns and energy use has been received enthusiastically but also criticised strongly. In this paper concerns are expressed about the role accorded to individual travellers and the wider space-time context of cities in the empirical-analytical work by Kenworthy and colleagues. To investigate the seriousness of these concerns, the data collected by Kenworthy and colleagues for European, Canadian and US cities in 1990 have been augmented with information on housing, urban development history and the sociodemographic situation. Regression models are described in which the role of urban form is investigated while account is taken of other relevant factors. The empirical analysis suggests that the space-time context of cities should be taken into account in aggregate-level comparisons of the relations between urban form and transport. Policy recommendations based on the original data may be reconsidered and tailored to the space-time context and population characteristics of cities.  相似文献

This paper contributes to research on daily mobility experience of (im)migrants in cities and expands the conceptualizations of mobility by examining intentionality and its relations to locality. Through place-based research on mobility and immobility of Chinese (im)migrants in Flushing, Queens, New York City, this paper explores: 1) mobility patterns of recent (im)migrants in an urban setting; 2) the constraints, resources and their coping strategies for everyday mobility; and 3) the dialectal relationship between voluntary and involuntary immobility, and between mobility and ethnic communities. This study reveals that immobility is not always the result of inaccessibility, but structural barriers in the broader society such as socioeconomic inequality and racial discrimination. Involuntary immobility encourages overdependence on locality. With its high place accessibility, Flushing provides (im)migrants with a plethora of ethnic mobile resources, as well as social networks and community resources. The relative immobility among Chinese (im)migrants in Flushing is compensated by the flows and movements of people, goods and information both at the local and transnational scale. The contrast between insider-ness and outsider-ness further enhances their attachment to the local community and discourages them from moving. Thus, locality mitigates involuntary immobility but paradoxically nurtures voluntary immobility that hinders the transfer of potential mobility to actual mobility, and physical mobility to social mobility. Without considering locality, stillness is easily mistaken for immobility; without considering intentionality, accessibility is easily equated to mobility. Therefore, solutions to transportation equity do not lie solely in transportation accessibility itself, but more broadly in individual capability, immigration policy, labor market equality and community development.  相似文献

Many cities in the world seek to establish more sustainable urban transport systems with a view to reduce accidents, congestion, air and noise pollution, and to improve social interactions, liveability and amenity values. Against this background, this paper frames urban transportation as an issue of justice: contemporary transport systems are characterized by injustice, as they tend to favour and prioritize motorized transport, accepting that considerable environmental and social burdens are put on more sustainable forms of transportation, other traffic participants and society as a whole. To conceptualize ‘urban transport justice’, the paper discusses three dimensions where injustices are apparent: Exposure to traffic risks and pollutants; distribution of space; and valuation of transport time. It is argued that public and political recognition of urban transport injustices provides significant argument for changes in urban planning, transport infrastructure development and traffic management.  相似文献

In 2005, 10 million electric bikes were produced in China. Strong domestic sales are projected for coming years, raising concerns about the sustainability and potential regulation of this fairly new mode. Policy makers are wrestling with developing policy on electric bikes with little information about who uses them, why they are used, and what factors influence electric bike travel. This paper probes these questions by surveying electric bike usage in two large Chinese cities, Kunming and Shanghai. Demographic comparisons are made between the different modes and cities as well as differences in travel patterns. Electric bike users are found to travel considerably more than bicycle users. Also, most electric bike users would travel by bus if electric bikes were unavailable. This suggests that electric bikes are less of a transitional mode between human-powered bikes and full-blown automobile ownership, and more an affordable, higher quality mobility option to public transport.  相似文献

While the bicycle is commonly understood as a suitable alternative to fulfil most of urban mobility needs, adoption rates of this transport mode vary considerably among urban areas. Those at early stages of adoption, identified as starter cycling cities, face numerous challenges, reducing the effectiveness of policies and strategies. Much research has been dedicated at identifying social and physical environment conditions favouring the use of the bicycle. Assuming cycling potential results of a good combination of physical and socio-demographic factors, we set out to identify dominant contexts generating high levels of cycling potential. The previously developed Gross Potential for Cycling is applied to 21 Portuguese municipalities of different spatial contexts. By looking at the particularities of different typologies of urban territories, a set of k-means clustering analyses investigates which combination of factors contribute to the establishment of a high cycling potential.The results indicate that, in the set of case studies, high accessibility to schools and urban centralities are common in high cycling potential areas, regardless of spatial context. Three clusters were identified from the combination of the age profile of residents and the connectivity features of the territory, defining the main typologies of high cycling potential areas. As different urban typologies pose distinct configurations on the performance of the different evaluated indicators, these outcomes are crucial to inform policy makers on where to prioritize investment for the establishment of a new cycling culture.  相似文献

Cities, mobility and climate change   总被引:2,自引:0,他引:2  
Societies gain enormous benefits from travel, as economies have become more globalised and as the new communications infrastructure allows international networking and travel at a low cost. There has been a true internationalisation of all activities, and travel forms an essential part of that process. However, this mobility is fuelled by carbon, and there is clear scientific agreement that carbon emissions are affecting the global climate with irreversible long term consequences. Transport is the one sector where a reduction in energy use and emissions is proving to be extraordinarily difficult to achieve despite some success in urban areas. This paper focuses on cities, mobility and climate change, highlighting recent trends in both developed and developing countries. It is argued that the current situation is unsustainable, and that transport must contribute fully to achieving carbon reduction targets. An alternative is presented, based on the sustainable mobility paradigm (Banister, 2008) that looks at ways to reduce the need to travel in cities. The belief that high mobility and technology provides the solution is misplaced, as technological innovation can only get us part of the way to sustainable transport, and this may facilitate more travel. There are opportunities for cities to switch to low carbon transport futures, where vision and action are based on a combination of economic, planning and technological innovations working in mutually supporting ways. Potentially, the future is bright for low carbon transport in cities, but the real question is whether there is the commitment and leadership to follow such a path.  相似文献

Spain is one of the countries with the highest shared mobility fleet in the world. The shared use of motorcycles, also known as moped-style scooter sharing, has spread far and wide throughout the country at a dramatic pace in recent years. Despite its increasing popularity and impact on urban mobility, efforts devoted to the study of its spatio-temporal travel patterns are still scant. Based on the analysis of GPS records of an operator present in seven Spanish cities, this study aims to contribute to this research gap by analysing mopeds' location patterns over time and assessing how different dynamics influence its usage level and self-balance potential. Our study is replicable to different cities and different shared modes, since we propose a methodology to identify the most important origins and destinations over time and analyse the system's self-balance capacity based on spatial autocorrelation tools. These insights are useful for operators to adjust and optimise vehicle distribution routes and maintenance/recharge tasks, decreasing congestion and increasing efficiency. The results may also be helpful for policy makers when planning and offering effective policies and infrastructure to encourage shared mobility.  相似文献

Rapid urbanization and a drastic socioeconomic transition from the centrally planned system to a market system in China provide a rare opportunity of observing urban transport equity. Literature on urban transport equity in Chinese cities is increasing. However, our understanding of urban transport equity in China is dominated by individual empirical studies, and an overall picture remains absent. This paper contributes the first literature review on urban transport equity in transitional China. Two key questions are answered. They are how transport equity is understood and examined in China, and what progress can be made to obtain universal knowledge of urban transport equity. This paper addresses the two questions by engaging with recent theoretical dialogue between the political philosophy of justice and Western transport equity research. This theoretical dialogue reconceptualizes transport equity into the equitable accessibility distribution mediated by institutional architecture to achieve equality of social opportunity among people. Based on a critical review of equity-concerned China transportation research and its reconceptualization, we propose an agenda for furthering urban transport equity research in transitional China. This research agenda calls for a shifted research focus (a) on evaluating the accessibility distribution of specific transport projects and policy, (b) on unpacking the political economy of transitional urban transport governance that determines the triumph/failure of the pro-growth/pro-equity accessibility distribution in the real setting, (c) on tracking the impact of accessibility distribution on disadvantaged groups' socioeconomic status and social mobility and putting forward appropriate policy/institution to improve the accessibility of disadvantaged groups, and (d) on revealing how the emerging social trends (e.g., information technology revolution and the aging society) reshape the individual capability to move/accessibility distribution.  相似文献

The rising demand for residential development in the urban fringe of Christchurch, New Zealand, has led to an increase in car use and lengthening journeys, both of which have serious environmental implications. In light of this, the relationship between urban form and transport was investigated in Christchurch through the analysis of journey to work data from 1991 and 2001. Low density suburban areas were found to generate and receive the highest percentages of car trips in both 1991 and 2001. It was also found that the majority of work-trips involved suburb-to-suburb commuting, rather than to the centre of the city. Average trip length did not increase substantially over this period, although increases were apparent in separate modes. Multivariate regression analysis established that the key variable determining modal split and trip length was the distance the residence was located from the central business district. Results were similar when compared to larger cities elsewhere.  相似文献

In the year to August 2002, 15% of the New Zealand road toll was attributed to 15–19 year-old drivers. This is the highest percent of casualties by any five-year age group, with the motor vehicle accident risk peaking at 16 years of age. New Zealand has the highest road accident statistic for this age group in the motorised world. It has been proposed that the driver licensing age be raised from 15 to 17 years of age. A 1998 Parliamentary Select Committee rejected the final proposal of a minimum driver licensing age of 16, on the grounds that such a rise would disadvantage rural youth through less accessible employment, educational facilities, social, and recreational activity, due to inadequate transport alternatives. This paper presents the results of research that examined the impact of the minimum driver licensing age on youth mobility. High school students were surveyed through interviews, questionnaires and travel diaries. It was concluded that the social benefits of raising the minimum driver licensing age to 17 years of age outweighed the social benefits of the status quo, as only minimal number of essential trips were totally dependent on youth acquisition of a driver licence.  相似文献
