Despite the growing development of tools that can integrate land use and transport, the desired integration is still illusive in daily practice. To address this gap, the current study uses spatial metrics, a set of methods traditionally used for studying changes in the spatial structure of landscapes, which are translated into the domain of transport planning. It examines how spatial metrics can be integrated into “Land Use Transport” strategy-making, and how useful they are according to the practitioners’ perceptions. A Light Rail Transit corridor in Granada (Spain) provides the empirical focus of this research. Land use characteristics such as: land use mixing, land use diversity and green areas connectivity were successfully studied using spatial metrics, and they were used to map three “Land Use Transport” strategies: (i) proximity dynamics and non-motorised modes; (ii) modal shift from cars to Light Rail Transit system; (iii) shared spaces between motorised and non-motorised modes. Practitioners perceived that spatial metrics could improve the “Land Use Transport” strategy-making process in comparison with traditional methods used in practice. However, certain shortcomings related to the usability of spatial metrics are also highlighted and discussed. This study concludes with a reflection on research challenges for adapting spatial metrics to transport practice. 相似文献

Increasingly, the debate on freight transport and logistics involves the challenge of sustainable development. Key objectives of sustainable or “green” freight logistics systems are the mitigation of negative environmental and human health effects of distribution operations and the realization of a major modal shift in transport preferences, while at the same time achieving internal generalized cost efficiency and quality of services. Pursuing these goals requires the introduction of a range of measures. These measures call for private and public actors to take up various initiatives and adopt policies. Usually, it is more effective to combine different actions into an integrated package of measures than to introduce single instruments in isolation.This article explores the nexus between sustainability and port hinterland container logistics. In particular, the methodology and results of an empirical analysis based on applications of a network programming tool called the “interport model” are presented and discussed. The model enables an examination of all possible effects on inland container flows and their associated internal and external costs due to public and private initiatives in the field of port hinterland container logistics. The empirical analysis aims to evaluate the impact of a set of simultaneous policy options and operational measures on the competitiveness and sustainability of hinterland multimodal distribution of import and export containers handled at the seaports of the Campania region located in Southern Italy. The loading units can transit through the dry port facilities (the so called “interports”) located in the same region and/or through extra regional railway terminals, before reaching their ultimate inland destinations or the seaports. The integrated package of measures simulated by means of the model includes: (i) infrastructure policy, (ii) improvements of rail services, (iii) regulatory changes in terms of customs authorizations and procedures, (iv) removal of technical and legal barriers to fair and non-discriminatory competition in the market of rail traction between regional seaports and interports, (v) new business models integrating container logistics operations between seaports and interports, and (vi) social marginal cost charging of transport operations. Once this package of instruments is introduced, higher private and social cost efficiency of port hinterland container distribution through the investigated regional logistics system can be achieved. For instance, it has been estimated an annual saving of the order of about 12,660 tonnes of CO2 equivalent emissions from transport corresponding to an external cost reduction of 0.27 million euros from the observed real life situation, whereas the estimated saving in terms of air pollution (CO, NOx, PM, SO2, VOC) from transport is approximately 220 tonnes per year corresponding to an external benefit of 1.31 million euros.The most immediate priority appears to be the customs and intermodal logistics integration of seaports and interports by means of full implementation of the “extended gateway” concept as a way to increase the rail share of modal split and improve the overall cost efficiency of the system. In addition, the simultaneous introduction of a social marginal cost charging policy can contribute to make the regional interports a viable solution to expand the hinterland reach of the regional seaport cluster. 相似文献

Public transport subsidies play an important role in the present Belgian mobility policy. The introduction of “free” bus transport in Hasselt in 1997 was an important event. Later, the Flemish government in cooperation with the regional public transport company elaborated the so-called “third-payer system” for target groups. The price of public transport is not paid by the user or the provider, but partly or completely by a “third party”. In how far these measures contribute to a more sustainable mobility system has caused much debate.In the academic year 2003–2004, a “free public transport” initiative was introduced for the students of Flemish colleges and universities in Brussels. These students had the opportunity to obtain a refunded annual season ticket on Brussels public transport. Brussels was selected for the case study, because in the same city there is a group of students that benefits from the measure, and another group (students from French speaking universities and colleges) that does not. In order to examine the effects of this measure, we conducted a survey among the students to examine their present travel behaviour (number of trips, motives, modal choice …) and the changes with the travel behaviour of the previous year. In addition we compare the current travel behaviour between the students benefiting from the measure, and those who do not. 相似文献

The mechanism of change in society is discussed in terms of power and interest groups, and some of the past changes in transport technology are examined in terms of the degree of threat posed to the established order and the interest groups benefiting from change. On the basis of such a power/benefit model, three of the new transport technologies which have been proposed — “guideway”, “dial‐a‐bus” and “network cab”, are discussed as to their likely social and political acceptability. 相似文献

为了遏制境外新冠肺炎疫情输入风险的高发态势,中国民航总局出台了调控航班的"五个一"措施。对于中国为防疫而采取的措施,美欧表示了不满,认为我国单边违反了航空运输协定。本文阐明采取相关防疫措施的国际立法依据是《国际卫生条例》第2条总目标及第43条有关额外措施的规定,从措施的实施效果与当前新冠肺炎疫情传播的严峻程度看,调控航班的措施是符合条例中的"保护性原则"、"比例原则"和"科学原则"的。 相似文献
