Walking and participating in activities outdoors in old age can be restricted both by the physical capacity of the individual and by the maintenance and/or the design of the outdoor environment. The purpose of this paper is to compare frequency of walking and frequency of activity outside the home, reported environmental barriers and valuation of the outdoor environment between two areas, in one of which there was an intervention in the outdoor environment 5–8 years prior to this study. The paper is based on a questionnaire sent out in 2011, to all residents 65 years and older in two different areas, the Study Area, an area with an intervention, and the Reference Area. The results show that reports on functional limitations, use of mobility devices and walking difficulties were similar in both areas. Despite that, respondents in the Study Area had a significantly higher frequency of walking and they also participated to a higher degree in activities than respondents in the Reference Area, even though they reported more environmental barriers. The valuation of the outdoor environment was, however, similar in both areas. The results indicate that older people benefit from interventions in the outdoor environment. However, the results also emphasize the importance of good maintenance of the environment. 相似文献

This paper proposes an accessibility-based spatial mixed logit (SML) model with panel data structure to examine the impacts of High-Speed Rail (HSR) on land cover change in large urban areas. Using data between 1990 and 2006, impacts of the Spanish HSR on Madrid’s Atocha railway station influence area – a 20 km radius buffer centred on the station – were investigated. To model the HSR impacts, besides socioeconomic variables, the development of both local and regional transportation networks with corresponding accessibility improvement is also taken into account to segregate the impacts of land-cover change brought by different sources of accessibility measures. In this study, two SML models are used: one incorporates regional accessibility indicators as a base model, and the other does not, acting as a control model. The model estimation results reveal that the reduction of the local and regional weighted travel average time has positive impacts on the Atocha station catchment area’s urbanised land-cover rates. Although the base and control models both achieve high goodness-of-fit values, the base model that considers regional accessibility reveals a better goodness-of-fit statistic and is more robust than the control model. It is concluded that the improvement of regional accessibility due to the arrival of HSR at Atocha station plays an essential role in the urbanisation of land cover changes in the study area. 相似文献

北京流动儿童义务教育设施的空间不均衡研究——以丰台区为例 总被引:4,自引:0,他引:4
以北京以及丰台区的适龄流动儿童分布和公立小学分布数据为例,采取社会地理学空间匹配的分析方法来测度流动儿童接受义务教育的空间不均衡性。结果显示,无论在市域、城区还是街道尺度,流动儿童就学需求和教育资源供给之间的空间不均衡现象都存在。据此,建议在学区划定时不仅要考虑常住户籍家庭儿童的数量,也要考虑校区吸引流动儿童的数量,并在流动人口集中的城乡结合地带,应尽量增设新的教育设施;或在现有教育资源的情况下,借助集体通勤方式提高这些教育设施的可达性,使更多的流动儿童得到就近接受义务教育机会。 相似文献

The present rapid urban growth of cities from developing countries causes negative externalities such as lagging infrastructure development. In combination with rapidly rising motorized vehicle use this leads to severe traffic congestion affecting the mobility of the urban residents. Therefore many urban governments are planning to improve their transport and mobility situations with mass rapid transit systems of which a bus rapid transit (BRT) is a rather easy system to implement at reasonable costs. However, due to high urban inequalities the effects of urban traffic and potential improvements of the urban transport system for the diverse group of urban residents can differ significantly. In our case study Kampala (Uganda) four main groups were identified through cluster analysis of socio-economic and residential data gathered through interviews: extreme poor, poor, middle income and rich. Each group experiences a different mobility with the extreme poor being the most vulnerable group. The planned BRT system aims to decrease the average travel time but risks to exclude the lowest income class since not enough attention is paid to the affordability of the system to all residents. Therefore we argue for a policy that works from bottom up and pays attention to the internal diversity of the population. 相似文献

Airport stops and flights on small airplanes as inhibitors of tourism-related air travel: A case study 总被引:2,自引:0,他引:2
This article discusses the extent to which prospective tourists' concerns about airport stops and flights on small airplanes inhibit air travel to tourist destinations, drawing on data from telephone surveys conducted in the Dallas–Fort Worth, Texas area. Respondents were queried about the extent to which one airport stop, two airport stops, and one airport stop followed by a flight on a small, propeller-powered airplane, respectively, would deter them from flying to a destination 1096 miles (1764 km) away. Findings suggest that marketers of similar destinations in similarly distant markets that are accessible by air only after two airport stops risk having their promotional appeals ignored by roughly half those who would prefer to reach such destinations by air. Moreover, those most concerned about such flight schedules were more likely than other respondents to have high incomes and to use the Internet to obtain vacation or travel information. 相似文献

Temporal and spatial variability of agricultural land loss in relation to policy and accessibility in a low hilly region of southeast China 总被引:1,自引:0,他引:1
The temporal and spatial patterns in land use change in a low hilly region in southeast of China was analyzed from maps of converted agricultural land for 1999–2006. The factors driving farm land conversion was analyzed using logistic regression models. The amount of agricultural land loss varied temporally, and the spatial distribution of converted agricultural land patches decreased from low to high altitudes in the study area. Analysis using logistic regression models showed that good accessibility sped up the conversion of agricultural land to other uses, the elevation of a parcel lowered the risk of conversion, and agricultural land conversions are highly correlated with its adjacent or neighboring parcels’ land use, with the probability of being converted decreasing as the distance to nearest construction land increases. In addition, land use policy, especially the land use regulation policy issued by the central government decreased the agricultural land loss, and the more stringent regulation on cultivated land conversion lowered the possibility of conversion from cultivated land to other use. 相似文献

Since the turn of the century especially small, local retailers struggle with the advent of e-commerce. It is hence no surprise that the retail sector is one of the hardest-hit sectors in the current pandemic. To understand the short- and longer-term impacts of COVID-19 on retail, we conducted two surveys to understand ongoing changes in the sector. By contrasting changing consumer behavior with the actions taken by local retailers, we assess whether the current pandemic is potentially a catalyst for e-commerce in Belgium. We do this based on a newly constructed framework of e-retail accessibility, as the differences between online and physical retail require a revision of the traditional economic geographical perspective on retail performance as introduced by Christaller (1933). We conclude that the COVID-19 pandemic holds ample opportunities for an increase in the three components of e-retail accessibility, but that a lack of professionalism might prevent traditional local retailers to retain a share of the expanded online market. This could well mean the final blow for local brick and mortar shops if, as is predicted, the share of online shopping in total retail expenditure remains high after the pandemic. 相似文献

ABSTRACTNew public transport infrastructure is expected to improve accessibility for local residents, and thus contribute to increased land value. The contribution that a bus rapid transit (BRT) system can make to increased land value is less certain than for rail-based systems, with the literature mostly containing bus-based examples from developing countries with extensive BRT networks. This article considers a BRT system named the Liverpool–Parramatta Transitway (LPT) that was implemented in southwestern Sydney in 2003 to improve public transport accessibility in the local area. A repeat sales model is constructed to investigate the impact of the LPT on residential housing prices and accessibility changes using repeat sales data from before and after the opening of the LPT. This identified little price difference between properties close to LPT stations and outside of the area that could be considered as affected by the LPT service coverage. This outcome is at variance with the theoretical underpinning of land value uplift and other empirical evidence relating to the LPT. Hedonic models using the same repeat sales data investigate the study area in more detail, stratifying the sample by housing type and by comparing separate before and after models. These research outcomes identify the extent to which the BRT system has an impact on local housing prices through accessibility improvements to the study area and provide a deeper understanding as to how the quantification of land value uplift from BRT represents one element of the wider economic benefits of a BRT system. 相似文献

This paper analyzes how location has affected, in the second half of the twentieth century, the population growth of 2889 municipalities in Switzerland. The analysis demonstrates the temporal relativity of location attributes, even for small territorial divisions, such as the Swiss cantons. However, we also show that, both absolute and relative location attributes have weakened over time as population growth predictors, apparently due to improving road infrastructures, and growing motorization. The study has been made possible by a detailed historical population and accessibility database available for Swiss municipalities. To the best of our knowledge, no database of such scope and quality is available for any other European country. 相似文献

This paper explores the idea of mobility for recent refugees who have resettled in a non-traditional immigrant destination in the northeastern U.S. It is based on a multi-year qualitative study of travel behavior, preferences, and needs amongst these new arrivals in a small city in the state of Vermont. As a result of their experiences of both forced displacement from their home as well as stasis within camp settings and the refugee determination process, refugees are an example of what some have called “a dialectic of movement/moorings” (Urry, 2003: 125), both on the move and trapped in place. Their resettlement in the U.S., as this paper illustrates, may represent a further extension of this dialectic—placed by government agents in new immigrant reception areas not of their own choosing, forced to commute long distances and into unfamiliar environments for work and limited in their abilities to access healthcare, education and employment (amongst other services) due to a range of transportation barriers. I argue in this paper that refugee mobilities in a new settlement site are about more than inconvenience: barriers to movement may constitute obstacles to acculturation, integration, self-empowerment, and community building. 相似文献
