基于TransCAD的"一路一线"公交布线方法仿真研究

“一路一线”是近年来提出的一种公交布线新思路,目前还没有在实际中得以应用。为了验证“一路一线”公交布线方法的可行性,以佛山南海中心城区桂城为研究对象,运用仿真软件TransCAD建立起公交仿真系统。在对仿真对象公交线网现状进行仿真校验的基础上,再采用“一路一线”的公交布线方法重新设计其公交线网．进行仿真。为了评价“一路一线”公交布线方法的仿真效果,从设施水平和服务水平两个方面设定评价指标,分别对现状公交线网和采用“一路一线”方法布设的公交线网仿真的结果进行了比较、评价。该项研究对验证“一路一线”公交布线方法的可行性进行了有益探索,为城市公共交通的改善尤其是新兴城市公交线网的设计提供借鉴。     

面向高速公路交通调度的动态数据融合

在高速公路交通动态数据融合需求分析的基础上,采用环形线圈和微波检测器建立多检测器动态数据的现场试验站,通过多检测器组合方式构建数据检测方案;应用基于自适应加权和改进BP神经网络的数据融合方法,建立交通动态数据融合模型,研究高速公路同一时间、相同断面的多检测器的数据融合。现场试验与检测数据分析表明：基于改进BP神经网络融合方法所获得试验数据的平均相对误差较微波和环形线圈各自的精度提高了10％-20％。     

上海集装箱运输的现状与发展思考

在调查上海集装箱港航企业基础上,分类地统计了有关上海集装箱运输的数据。基于对上海集运产业的认识,结合本次调查所掌握的实际情况,对上海集运产业的发展提出了若干建议。在软件建设方面,尽快形成综合开发队伍,提高管理系统软件的开发层次和开发速度;加快电子单证、电子签名等的技术研究与立法工作;开发更为完善的生产作业指挥系统。在企业发展战略方面,着重从稳定货源、加强合作、着力开拓三方面进行了论述。     

The provision of home to school transport in Northern Ireland

The provision of home to school transport is an important element of transport policy in local communities. This paper examines the provision of home to school transport in Northern Ireland. It reviews the nature of demand and provision, and the costs involved in providing the current system of home to school transport compared to other parts of the UK. In addition it also discusses issues surrounding the use of the statutory walking distance, safety on buses including the provision of ‘3 for 2’, standing on buses and seatbelts in Northern Ireland.     

蒙西地区国际运煤通道研究

蒙古国的塔本陶勒盖煤田焦煤储量居世界第一位。通过分析甘其毛都口岸的功能定位和煤炭运量,为打通国际运煤通道,组成蒙西地区铁路运输网络,针对口岸发展提出规划建设蒙西地区国际运煤通道。并从通道构成及主要技术标准,以及运输组织、车流组织、列车编组、通过能力等方面,探讨运煤通道的运输组织模式。     

关于秘鲁鱼粉自热自燃原因的探讨

近来，秘鲁鱼粉在远洋运输过程中屡次发生自然事故。本文就这一现象从鱼粉的组成、性质、抗氧剂的处理程度以及运输积裁条件加以分析，阐述了鱼粉发生自燃的诸多原因。并根据实际案例、秘鲁当地对鱼粉抗氧剂处理过程的现状及商检部门的检测方法等方面的资料分析，指出了秘鲁鱼粉在运输过程中发生自燃的主要原因是鱼粉中的抗氧剂分布不均匀，致使那些抗氧剂浓度不足的鱼粉在运输途中抗氧剂含量逐渐消耗而发生氧化反应，产生大量的氧化热，达到鱼粉的自燃点而发生自燃。     

Effect of environmental awareness on electric bicycle users’ mode choices

Travellers’ environmental awareness can affect their mode choices. The primary objective of this study is to identify the effect of electric bicycle (e-bike) users’ environmental awareness on their mode choice when the use of e-bikes is prohibited in urban areas in China. The data were collected via a questionnaire survey administered at ten locations in Nanjing, China. Using mixed multinomial logit (MMNL) models, we examined the relationship between the e-bike users’ mode choice and their environmental awareness, combined with socioeconomic and demographic characteristics and trip attributes. The results show that the level of environmental awareness, gender, age, education, income, the ownership of car and conventional bike, and trip distance affect e-bike users’ choices significantly. Those with a high level of environmental awareness are more likely to choose zero-emission transport modes. A stratified analysis reveals that the effect of environmental awareness is associated with their original transport mode choice prior to their use of the e-bike. With a high level of environmental awareness, original car users tend to opt for moderate- or zero-emission modes; original bus and metro users incline to choose a zero-emission mode or their original mode; and few original cyclists and walkers favour moderate- or high-emission modes. The results of the current study provide transport authorities with insights to establish sustainable urban transportation management policies and strategies to increase the share of zero- and low-emission transport modes.
