地铁客流特征分析与运营措施的优化

客流是城市轨道交通运输工作的基础,是编制旅客运输计划和列车开行方案的依据。客流是动态的,分析研究客流在时间上、空间上的动态演变规律,配备与之相适应的运输能力,是城市轨道交通运输组织和行车组织工作顺利进行的前提。本文以南京地铁3号线为例,根据该线在地铁线网上的位置及沿线连接的站点,在分析客流时间和空间上分布特点的基础上,对地铁3号线运营组织工作提出了优化措施。     

长益常城际铁路速度目标值的选择

速度目标值是城际铁路设计时的核心指标,在选取时主要以适应客流需求、与区域其他交通运输方式相协调、与沿线社会经济发展相适应为原则,体现有利于吸引客流、减少工程投资和运营成本的效益最大化原则。速度目标值的选择主要通过本线客流特点、时间目标值的选择和具体多个速度目标值的比选得出。文中以长沙—益阳—常德速度目标值的选择为例,阐述铁路设计中客运专线速度目标值的选择方式和方法。

Will China’s airline industry survive the entry of high-speed rail?

This study investigates the effects of high-speed rail (HSR) services on Chinese airlines. Our analysis suggests that the HSR service will be competitive in terms of network connectivity, total travel time and cost efficiency. On the other hand, growth of the Chinese airline industry has been unbalanced in terms of traffic distribution, airline network development, airport capacity and share of international traffic. While the long term prospects of Chinese airlines are bright, the carriers must develop effective hub-and-spoke networks and increase their competitiveness in international markets in order to achieve sustainable growth in the coming years. For the Chinese government, continued investment at hub airports and support to low-cost carriers are also necessary.     

关于2000年沿海客运发展的研究

Safety culture on board six Swedish passenger ships

This paper presents the results of a Swedish study on maritime safety culture. The study aims to increase knowledge about the characteristics of safety culture in the maritime setting and about the relationship between safety culture and organizational climate. Such knowledge can be vital in the process of developing and improving safety culture. The paper reports the results of safety culture assessments on board six Swedish passenger ships in international traffic, using observations, questionnaires, and interviews focussing on 508 employees who completed the questionnaires. The results of the assessments revealed a generally good existing safety culture. Differences in individuals' safety culture perceptions were found between ships, vessel type (high-speed craft versus Ropax), and hierarchical working position. Important relationships between organizational climate and safety culture were also found. A comparison with other transport sectors where the same safety culture assessment had been applied yielded that passenger shipping has an average safety culture score level that falls between air traffic control and airport ground handling. The method of assessment, which can be used by shipping companies and vessel crews, identified specific areas of concern in the safety culture that could support continuous improvements of safety and safety culture.

Measuring the effect of low-cost carriers on regional airports' commercial revenue

This paper measures the effect of low-cost carriers (LCCs) on British regional airports' commercial revenue using panel data analysis. The evidence shows that although LCCs have significant impact on airports' commercial revenue, their contribution is smaller compared to other carriers. The empirical results indicate that holding other variables constant, on average, each additional LCC passenger boosts airport commercial revenue by £2.87, while each additional other carrier passenger raises commercial revenue by £5.59. These results are relatively stable across different models. The findings have important policy implications for aviation strategy at the regional level and beyond.
