Did highways cause the urban polycentric spatial structure in the Shanghai metropolitan area?

Based on LandScan population data, land use data and highway data for the Shanghai metropolitan area from 2000 to 2015, this paper studies the impact of highways on the formation of built-up areas and subcenters to explain the emergence of the urban polycentric spatial structure. The findings are as follows. (1) The dispersion of the population strengthens the polycentric spatial structure of the Shanghai metropolitan area. From 2000 to 2015, the number of subcenters increased from 72 to 118, and their area expanded from 1347 km² to 3469 km². In addition, the main centers lost 12.7% of the population share, while the subcenters gained 12.47% of the population share. (2) Highways play a significant role in promoting urban spatial expansion and the formation of subcenters in the Shanghai metropolitan area. With every 1% decrease in distance to the nearest highway, the probability of an undeveloped area becoming a built-up area increases by 1.53–6.74%, and the probability of a built-up area becoming a subcenter increases by 11.93–20.92%. The results are robust to a series of supplementary tests, such as the replacement of explained variables or explanatory variables and the adoption of instrumental variables. (3) The Chinese government plays an important role in urban polycentric spatial development. New district and development zone policies represent two important mechanisms of highways affecting urban polycentric spatial development.     

Tourism and electricity consumption in 9 European countries: a decomposition analysis approach

ABSTRACT

Tourism is a major economic activity constituting one of the main sectors in economic terms. European countries traditionally play a significant role in the overall international tourism flow. However, while tourism has a noticeable positive impact on economic development, it also contributes to environmental degradation by increasing energy consumption and therefore emissions. This paper analyses the relationships between Hotel and Restaurant electricity consumption and tourism growth in 9 European countries during 2004–2012, for which there is a sufficient amount of data available. A decomposition analysis based on log-mean Divisia index method (LMDI I) is conducted to examine electricity consumption on this sector and their components. Five decomposition factors are considered: energy intensity (EI), physical capital intensity (KI), physical and human capital relationship (KL), human capital intensity (LI) and the tourism factor (T). Results show the evolution of energy consumption related to this sector, identifying the driving forces that have influenced it.     

Mitigating externalities of terrorism on tourism: global evidence from police,security officers and armed service personnel

ABSTRACT

In this paper, we investigate the role of security officers, the police and armed service personnel in dampening the effect of terrorism externalities on tourist arrivals. The temporal and geographic scopes are respectively 2010–2015 and 163 countries. Four terrorism measurements are used. They include the number of incidents, injuries, fatalities and property damages. The main findings indicate that armed service personnel can effectively be used to modulate the damaging influence of all four terrorism externalities in order to achieve a positive net effect on tourist arrivals. Conversely, the corresponding moderating role of security officers and the police is not statistically significant. Moreover, violent demonstrations and homicides have a harmful effect on tourist arrivals while the number of incarcerations displays the opposite effect. Policy implications are discussed.     

Extending the dimensions of personal exposure assessment: A methodological discussion on perceived and measured noise and air pollution in traffic

BackgroundThe exposure to air pollution and noise is severely impacting people's health and is especially high alongside urban road- and rail-traffic. In traditional exposure research, air pollution and noise are monitored with stationary measurement devices or based on models. During the last years, mobile measurement techniques with GPS-tracking have increased. Moreover, studies have investigated another dimension of personal exposure: the perceived exposure.AimMost of these studies make use of quantitative methods such as surveys, complemented by stationary or wearable sensors. Little research exist that applies qualitative methods to examine how people experience and perceive exposure on-the-move, contrasting it to actual measurements. The aim of this paper is to discuss the potential of a novel method, which extends the dimensions of personal exposure by including the situational context of exposure perception.Methods/case studyFirstly, different methods for exposure research are presented. Secondly, we introduce a novel mixed-method approach, exploring cyclists and pedestrians perceived and measured exposure on-the-move by combining mobile interviews (Go-/Ride-Alongs) and wearable sensors. We will present the methodological findings using a case study and have a quantitative method (smartphone questionnaire, wearable sensors) as a reference.Results and discussionThe differences of perceived and measured exposure, proven through the reference method, are a result of different situational contexts as shown by the mobile interviews (knowledge, embodied experience, life situation, activities). The methodological findings show, that mobile methods complemented by wearables introduce new dimensions of personal exposure: they shed light on the situational contexts that affect exposure perception during commute.ConclusionWe argue that both, perceived and measured exposure to air pollution and noise, need to be considered simultaneously. Complementing mobile interviews or surveys with wearable sensor data improves the understanding of urban dwellers requirements for healthier mobility. Potentials of these methods should be investigated further, both in research and for supporting urban transport planning decisions adapted to people's needs.     

Geographic Information System (GIS) Analysis of Impacts in the Tourism Area Life Cycle (TALC) of a Mediterranean Resort

Tourism in Spain has evolved from being a residual sector in the economy during the 1950s to become at present the main source of wealth in the country. The Spanish Law of Centres and National Tourist Interest Areas of 1963 created numerous new resorts on the coast whose life cycle is now over 50 years. On the Mediterranean coast, urban development and tourism model processes have been developed with major feedback to each other. In this context, it is particularly interesting to evaluate the results obtained since the decade of the 1960s in order to achieve sustainable tourism. This paper analyses a paradigmatic case study located on the Spanish Mediterranean coast. A diagnosis that explains the evolution of the life cycle tourist destination as a consumer product is carried out using geographic information system analysis of the urban plot. The mutation of the target customer, the real estate overcrowding, or the seasonality of demand will be the variables to be evaluated in order to assess the final return of the managed product.

‘When buying into the business,we knew it was seasonal’: perceptions of seasonality in Central Otago,New Zealand

Although the majority of the academic literature makes a convincing economic case when suggesting that seasonality is problematic, it is, arguably, equally important to consider whether businesses themselves perceive seasonality as a distinct problem. This paper considers the extent to which businesses and operations, variably involved in tourism, perceive seasonality. A case study of the Central Otago region of New Zealand is offered. The results suggest that although seasonality is perceived as a salient issue for the sector itself, it is not universally perceived to be inherently problematic from the perspective of the individual business/operator.

The planned and the perceived city: A comparison of cyclists' and decision-makers' views on cycling quality

IntroductionTraffic jams, congestion and pollution demand sustainable modes of transport. To increase the appeal of cycling, bicycle-users' perceptions and needs should be acknowledged by decision-makers. However, traditional transport planning mainly focuses on quantitative, infrastructural data. To address this gap, this study explores to what extent decision-makers are aware of cyclists' needs and perceptions. Furthermore, the study compares the assessments about cycling of decision-makers and cyclists in the city of Leipzig, Germany.MethodsQualitative Interviews with 13 cyclists and similarly structured interviews with 6 experts from politics and planning were compared using qualitative content analysis. Two main topics were examined: (1) the reasons for cycling and (2) the perceived environment (built, natural and individually perceived). To integrate the spatial context, the interviewees draw sketch maps which were analyzed and compared using geo-information systems.ResultsExperts assume that main roads with cycling infrastructure are decisive for fast and safe cycling and cyclists agree with this statement. However, cyclists further refer to the positive effects of green spaces, the experience of the natural environment (e.g. fresh air) as well as the healthy and recreational effect of cycling. Cyclists prefer taking side roads and are prepared to use detours to integrate the natural environment and avoid traffic jams, noise and air pollution – these aspects were rarely acknowledged by decision-makers.DiscussionWe conclude that urban planners need to involve cyclists' perceptions more explicitly. Integrating cyclists' experiences in planning processes using sketch maps and interviews are beneficial, complementing quantitative approaches to enhance the understanding of cyclist behavior. The findings are essential to stress the importance of participatory approaches in urban planning to promote a sustainable, healthy and environmentally friendly urban development appropriate to citizens' needs.     

Composite indicators of sustainable urban mobility: Estimating the rankings frequency distribution combining multiple methodologies

The contribution of this paper consists in applying several techniques to estimate a composite indicator of sustainable urban mobility for 116 Italian provincial towns, as proposed by Luzzati and Gucciardi (2015). The aim is to provide the decision-maker with a richer set of information on sustainable mobility, making explicit the impact of the techniques used on the values obtained. A set of 16 indicators with a nested structure has been selected and 33 combinations of normalization, weighting, and aggregation techniques are applied. The results are presented by city, by city groupings (size and location), and focusing on the ten largest Italian cities. It is found that small cities perform better in terms of sustainable mobility than medium or large cities. As expected, in some cases (e.g., Milan) the intervals of the results obtained are quite large, indicating that the techniques used to normalize, weight, and aggregate the indicators highly affect the performance indexes. In other cases (e.g., Rome) the results are stable across methodologies.     

Questioning gender stereotypes: A case study of adolescents walking activity space in a small Central European city

BackgroundThere has been a lack of research on the gender differences in spatial attributes of adolescents' walking activity space (WAS). Moreover, while other literature shows girls walking less through city centres than boys, there are limitations concerning the absence of its precise definition and spatial delimitation. Additionally, the morphological structure of city centres, and differences in their constituent parts have not been considered.AimsIn this study, the extent to which the area is used for walking by girls and boys, as well as gender differences in spatio-temporal walking patterns during weekdays were investigated, with a special emphasis on the city centre and its constituent parts.MethodsUsing a mapping activity, self-reported spatio-temporal walking data from 304 adolescents (168 girls) aged 13–16 years were collected. To fill the gap in existing research, the study was conducted in the central ward of the small medieval historic city of Banská Bystrica (Slovakia). Attributes of WAS were calculated using Standard deviational ellipse analysis and Kernel density method. Gender differences in walking were tested by non-parametric Mann-Whitney U test for the city centre (defined by a pedestrian zone), its constituent parts (streets and squares) and for the whole ward separately. In all the cases, time of the day was considered.ResultsDespite the distinction between streets and squares in the city centre, no significant gender differences in walking were found, which is in contrast to the prevailing body of literature. Yet, a slight predominance of girls in the squares (regardless of the time of day) and boys in adjacent streets and alleys (after dark) was present. The WAS of girls was more compact compared to that of boys, with the biggest difference after dark.ConclusionsThe compact WAS of girls is in line with existing research on adults, despite the absence of traditional gender roles of wife and mother during adolescence. In addition, there is a subtle indication that a pedestrianized historic centre with a high degree of open space in squares and visually enclosed adjacent alleys may create different conditions for gender differences compared to other types of urban cores. In the future, a more in-depth examination of the degree of enclosure in public space and its influence on walking patterns is necessary.     

Key research themes on governance and sustainable urban mobility

ABSTRACT

This article discusses the governance of sustainable urban development and in particular assesses the role of policy instruments to promote soft forms of governance associated with persuasion and coordination. These instruments are critically examined in terms of how they might help to promote greater policy integration and more sustainable development. Five types of strategies for promoting more sustainable transport policies are discussed: (1) policy indicators and targets, (2) benchmarking, (3) policy transfer and best practices, (4) policy experimentation/innovation, and (5) visioning/envisioning. The article is divided into four main parts. First, it presents an overview of recent trends in the governance of urban transport. Second, it examines the notion of policy integration, a central theme in discussions about sustainable transport and governance. Third, it considers how selected types of policy instruments might contribute to policy integration and sustainable urban development. Fourth, alongside the conclusions, suggestions are made for new research related to policy instruments and soft forms of governance in relation to urban transport.     

An analysis of air mass effects on rail ridership in three US cities

This paper examines whether daily weather affects ridership in urban transportation systems. When examining human–weather relationships, it is often advantageous to examine air masses, which take into account the entire parcel of air over a region. Spatial synoptic classification characterizes air masses based upon numerous meteorological variables at a given location. Thus, rather than examining temperature or precipitation individually, here we compare daily ridership to synoptic air mass classifications for three urban rail systems: Chicago Transit Authority (CTA), Bay Area Rapid Transit (BART), and the Hudson–Bergen light-rail line in northern New Jersey. Air masses are found to have a significant impact on daily rail ridership, with usage typically increasing on dry, comfortable days and decreasing on moist, cool ones, particularly on weekends. Although the comfort of a particular air mass changes throughout the year, seasonality is not a significant factor with respect to the air mass–ridership relationship. The results of this study can benefit rail system managers who must predict daily ridership or in the development of cost-benefit analyses for station improvements.     

Dense,mixed-use,walkable urban precinct to support sustainable transport or vice versa? A model for consideration from Perth,Western Australia

ABSTRACT

Within the majority of the literature on sustainable transport, it is accepted as ideal to arrange new urban growth in close proximity to major public transit services. While the literature on this subject of transit-oriented developments (TOD) is positive and optimistic, for the most part such assertions are conjectural. This article will attempt to fill this gap by revealing a modeling process undertaken for a local area's reurbanization project to understand the potential and limitations of several modes of transport to support the increased activity density in the precincts. Several of the most standardized policy levers were employed, such as parking ratios and mix of use and building height, and contrasted with the trip generation and transit mode's hourly capacity to reveal potential real-estate yields. The outcomes indicate not only the immediate yields but also the capacity for urban transformation due to each level of sustainable transport investments. The model is unique in that the capacity, parking ratios, and assumptions are highly transparent.     

CNG2020 strategy and airline efficiency: A Network Epsilon-Based Measure with managerial disposability

In this paper, we analyze the impacts of CNG2020 strategy on the efficiency of 29 international airlines during 2021–2023. Predictions are made through neural networks based on the empirical data from 2008 to 2015. Following the principle of CNG2020 strategy, we calculate the emission limit for each airline. Then we propose a new model, Network Epsilon-Based Measure with managerial disposability, to discuss the difference in efficiency of the airlines when the CNG2020 strategy is considered. The main findings are: (1) For most of these 29 airlines, the CNG2020 strategy has little influence on their efficiency. (2) The efficiency has little variation under the following conditions: when the carbon price is 8 $/ton CO₂-eq, when the price is 14 $/ton CO₂-eq, and when the price is 20 $/ton CO₂-eq. (3) Scandinavian is identified as the benchmarking airline.     

Does freedom of the press enhance inbound tourism?

ABSTRACT

This paper examines the effects of the freedom of the press on inbound tourism in 160 countries for the period from 1995 to 2016. By using the fixed-effects, the Hausman–Taylor, and the dynamic panel data estimation techniques, we show that a higher level of the freedom of the press promotes inbound tourism. The main findings are robust to consider the countries at the different income level, the inclusion of the various control variables, using the different measures of the freedom of the press, excluding the outliers, and excluding the observations in the different regions.     

Research agenda for low-carbon mobility: Issues for New World cities

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.     

Car ownership and urban development in Chinese cities: A panel data analysis

Growth in car ownership has significant impacts on the use of urban space and management of urban environments, which makes it a topic of increasing interest especially for developing countries such as China. The dynamics of and factors influencing ownership in Chinese cities need careful investigation. Using fixed effects models applied to annual panel data (1994–2012; 293 cities) this study aimed to achieve the following: 1) assess the relationships between car ownership and average annual income per capita, population, built-up area, road area per capita, urban population density, number of taxis and bus passenger volume; 2) examine the variation of these relationships across geographical regions (East, middle, and West China) and city sizes (cities with small, medium, large, and super-large populations). The results showed that car ownership was positively associated with average annual income per capita, built-up area, road area per capita, urban population density, and number of taxis at the national level. All associations, except with the number of taxis, varied significantly across geographical regions. Built-up area, road area per capita, and number of taxis had different associations with car ownership depending on city sizes. The findings improve the understanding of relationships between car ownership and urban environments vis-a-vis variations in income and infrastructure per capita, population density, and transportation alternatives. These results have important policy implications for managing cars and health problems related to cars in China.     

Key research themes on regulation,pricing, and sustainable urban mobility

ABSTRACT

This article considers both theoretical arguments and practical experience regarding a range of urban pricing and regulation policies, namely road pricing, public transport pricing and regulation, car parking policies, home and low-emissions zones, and regulation and subsidies to bring about cleaner vehicles. It concludes that effective urban transport policies require a consistently structured package of measures, and that the most urgent research needs surround the design of such measures to achieve their objectives while being financially sustainable and attracting public and political support.     

The jobs–housing relationship and commuting in Beijing,China: the legacy of Danwei

China’s market-oriented reform has not only revitalized the economy but also changed the physical structure of Chinese cities, which used to be largely determined by the socialist Danwei (or work unit) system. In order to understand the impacts of the reform and the influence of Danwei on jobs–housing relationships and commuting behavior, this study investigates whether there are differences in commuting behavior between individuals who live in houses provided by Danwei and those who reside in houses from private market sources in urban China. We apply the structural equations model to investigate the interactions between housing source (from Danwei or not), jobs–housing relationship, transport mode and commuting time in Beijing, the capital city of China. The results show that Danwei housing commuters have shorter commuting trips and higher usage of non-motorized transport mode than those who live in houses from the market sources. This finding implies that the diminishing influence of the traditional Danwei system and the market-oriented reform in urban development may have changed the jobs–housing balance and increased travel demand in Chinese cities.
