探讨铁路物流企业未来发展

铁路运输在我国占据很重要的地位,与公路运输、航海运输、航空运输来比较,受到行业垄断、运输成本低以及运力不足等很多因素的制约,铁路运输市场的竞争力比较小。我国物流产业发展迅速,传统的铁路运输方式已经不能够满足物流发展的需要,铁路系统企业需要加快物流发展的脚步,通过资源的整合,发展成为我国物流市场的主导力量。     

浅谈铁路客运专线桥梁施工资料的收集与整理

在铁路施工管理中,工程内业资料是一个很重要的组成部分。因此,工程内业资料的进一步规范和标准化是我们面临的共同课题。文章以本人参加的武(汉)至黄(石)城际铁路项目中的施工资料为例,和大家共同探讨一下铁路客运专线桥梁内业资料的收集与整理。     

低碳经济下公共交通运输管理研究

环境发展以及能源利用影响着公共交通运输管理,低碳运输在中国虽然只是起步阶段,但却面临着机遇与挑战。因此,应当系统地规划交通线路,建设现代综合运输体系,加快城市主、次干道和快速路建设,合理安排机动车道和人行道的建设,提高道路利用率,加强公共交通运输效率,真正实现快速流通,降低公共交通运输资金的耗费;重视公交轨道交通,提高服务质量,增加作为出行选乘方式的吸引力;合理规定排放标准,强化交通运输管理;完善信息系统,提高信息的综合运用,发展ITS智能运输,使用HT-UTCS等交通控制系统,同时重视交通法制教育,人人懂交通法规,依法交通,这样就能实现低碳运输。     

基于GNNM(1.1)模型的货运量及货运周转量预测

通过各种算法对货运指标进行有效预测,对于把握未来货运发展趋势有着非常重要的作用。文章将灰色预测与神经网络预测方法进行了有机结合,建立了一个基于灰色神经网络的预测(GNNM)模型。通过模型对货运量及货运周转量进行了预测,得到了较满意的结果,表明了模型具有较高的可靠性及实用性。     

对铁路工程价差系数的探讨

铁路工程目前的价差调整方式主要是采用相对于某种编制办法的基期价每年(或季度)由铁道部发布材料价差系数进行价差调整,本文阐述了铁路工程价差系数的发展过程及其特点,定量地分析了太中银项目"某项目部"铁路价差系数对其工程造价的影响,对铁路工程项目的材料价差调整具有一定的指导意义。     

民航运输业对区域产业影响的定量分析——以湖南省为例

利用《湖南省2002年投入产出表》,对湖南民航运输业与区域产业的整体关联特征、民航运输业的感应度系数与影响力系数、民航运输业的产业波及效应进行了定量测算。研究表明：作为一种派生需求,民航运输业对其他产业和外部环境呈现出强依赖性;从民航运输业的感应度与影响力看,民航运输业在国民经济各部门联系中呈现显著的＂后相关＂特性;从民航运输业的产业波及效应看,民航运输业对制造业的产值波及效应最大;在价格方面,民航运输业价格波动对制造业的影响最大,其次是旅游业。     

Children aged 9-14 living in disadvantaged areas in England: Opportunities and barriers for cycling

The aim of this paper is to take a holistic perspective to explore levels of cycling and opportunities and barriers to increase children’s safer cycling in disadvantaged areas in England. The study was one part of a larger study which explored the factors underlying the high level of road traffic casualties especially among children in the most disadvantaged areas of England and to explore how this impacts on mobility and quality of life. The methods involved a cross sectional survey comprising school based questionnaire surveys with children aged 9-14 and focus groups with parents who had children within this age range. The surveys were conducted in 2007 and the focus groups during 2008. 4286 children completed the survey and eight focus groups were held. Bike ownership (77%) was high, use in previous week moderate (39%) but only 2% cycled to school. Ownership was significantly lower in minority ethnic groups. Despite young children’s strong preference to travel by cycle (30%) than walk or go by car, most parents felt it was too hazardous. It is unlikely that these findings would be any different from the rest of England, however the combination of environmental and social factors may elevate the risks for young cyclists in these areas. This paper concludes that a number of barriers exist to increasing levels of cycling among children living in disadvantaged areas particularly amongst ethnic groups. These barriers could be addressed by environmental modifications to reduce speeds and by reducing the levels of antisocial driving and riding in residential areas and around destinations where children travel, by providing cycle training to improve children’s skills and parent’s confidence, and by providing secure storage facilities for bikes. Until these barriers are addressed it is unlikely that cycling will increase despite the strong preferences children have to travel by bike. Such preferences to cycle provide an opportunity for local authorities to act on.
