A mixture of potentially significant changes in technology, commercial structures, and social practices is currently entering the automobility system. These changes have the potential to combine together and lead to a substantial shift in the manner in which society fuels, owns, and makes use of its cars. This paper reports a research project that made use of focus groups to examine the narratives of British transport professionals concerning forthcoming developments in the automobility system. Specific attention was given to what the expectations for future change in automobility are, if these changes will likely lead to a transition toward a more sustainable system and the manner in which a transition of this nature could be facilitated. The oral testimony offered during the focus groups has been assessed qualitatively using thematic analysis. The results suggest that there is a commonly held view that the automobility system is entering a stage of flux, which may lead to considerable changes in system configuration. However, the attainment of a sustainable transition for the system will likely be inhibited by a series of institutional, societal, and physical barriers, which may restrict system developments. 相似文献

针对机场季节旅客吞吐量的特点,提出了基于趋势分解的机场季节旅客吞吐量预测方法,其基本思想是:首先根据机场季节旅客吞吐量历史数据的移动平均数,计算平均季节指数并进行修正,然后构建机场季节吞吐量趋势变动模型,从而构建航线季节客运需求分析模型。仿真结果表明该方法可行且结果具有较高的精度,可作为预测机场季节旅客吞吐量的有效工具。 相似文献

We analyze market shares for each public transport mode in total public transport ridership for the multimodal public transportation system of Athens, Greece. This analysis provides useful information for making investment decisions concerning the public transport infrastructure and for allocating subsidies. Due to the non-stationary properties of the data, cointegration techniques are applied to investigate the long run equilibrium relationships. Error Correction Models are implemented to estimate short run dynamics as well as the speed of adjustment from the short to the long run. Results suggest that fare and GDP are the main determinants of the public transport mode shares both in the short and in the long run. Findings also indicate the role of total ridership fluctuations in explaining variations in public transport mode shares. 相似文献

In Sub-Saharan Africa (SSA), inland export transport costs and time delays are much higher for landlocked countries, vary substantially between different geographic corridors, and exhibit substantial uncertainty. Unit costs and costs of time for land transport of exports are high for many agricultural products relative to metals and other high-value products. We illustrate systemic uncertainty in land and maritime transport for exporting by use of simulation. Relationships among uncertainty, infrastructure quality, and other features of logistics systems are highly non-linear, and can be potentially used to identify priorities for trade facilitation. 相似文献

CY Tung was the pioneer of innovation and the practioner of innovative theories in modern shipping, regardless of his huge oil tanker building, container transport, institutional management or resource integration. Tung, the shipping industry have called the pioneer of innovation, Tung's road to success is a story and history of continuous innovation. In his shipping career, adhering to the innovative concept, multi-use new shipping technology, and management practice, Tung had built a team with the ability to innovate. Tung's group, by integrating its human resources, contacts and production resources ultimately established himself in the highly competitive international shipping market and achieved his legendary of the world shipping tycoon. 相似文献
