属地化改革后民用机场运营效率的研究

属地化改革标志着航空业进入了新的发展阶段。运用DEA方法对我国30家民用机场的效率进行评估后发现,2006年以来我国机场效率明显提高,但是总体运营仍是无效的。对于不同管理形式、融资方式和企业规模的机场来说,其无效的原因和效率优化路径并不相同。这将影响我国航空业进一步改革的方向和相关政策的制定。     

基于成本分析的发车频率模型在广州BRT的应用

班车的发车频率对服务水平及成本控制都起着重要作用。发车频率低,可以降低成本,但是不能满足乘客需求,会引发一系列社会问题;发车频率高,虽然给乘客提供了更好的服务,但是却大大增加了运营成本。本文将在陈文进《大众运输路线服务模式构建之研究》中提出的基于成本的公交班车派发频率模型的基础上,增加环境因素的考虑对模型进行完善。再次本文将以LINGO为工具对模型进行简单求解,并将模型应用于广州快速公交对广州BRT的发车频率进行优化。     

电动轮自卸车电传动系统试验平台的可行性研究

文章依托科技部＂十五＂科研项目——＂交流驱动百吨级矿用自卸车的研制＂,介绍了电动轮自卸车的发展、原理和技术特点。为了满足电传动系统的试验需求,特别是对由柴油发动机、发电机、驱动电机及其测试和控制系统等构成的动力总成进行试验,建立了一个拥有不同驱动电机试验功能的试验平台。平台由变频异步电动机、交流同步发电机、驱动电机、测功机等机械设备和整流器、逆变器、励磁器等电气设备组成,采用CAN总线串行通信协议实现各电控单元之间的信息交换。通过发电机空载特性、外特性、驱动电机稳态运行性能等试验证明,该平台基本满足电动轮自卸车的各种试验条件,为驱动性能研究提供了良好的实验环境。     

Incorporating annoyance in airport environmental policy: noise, societal response and community participation

Airport capacity continues to be one of the air transport issues that creates the most concern. The major environmental constraint for airports is the noise generated by aircraft. Annoyed communities living around airports have become a limiting factor for airport capacity and operability. This paper brings together the existing literature in the fields of airport environmental capacity, non-acoustic factors of noise annoyance, NIMBYism and environmental conflicts. We also analyze the socio-environmental conflict between Barcelona airport and the community of Gavà Mar. This case shows that the lack of trust between parties, the impossibility of predicting noise exposure, the absence of opportunities for civil society to speak and the difficulty of accessing relevant information foster annoyance and mobilization in the communities that live around the airport. In addition, it is shown that, in such a situation, communities’ reactions can evolve to a post-NIMBY stage in which proactive attitudes replace reactive ones.

一种基于ISD1760的公交车语音报站系统设计

设计了一种基于ISD1760语音芯片的公交车语音报站演示系统。主控芯片采用了基于首款采用ARM cortex M3内核的stellaris系列中具有代表性的LM3S811,通过ISD1760的独立按键模式录制语音信息,然后利用ISD1760的SSI模式接口和LM3S811同步串行端口连接通信,实现语音芯片按照主控芯片发送的信息组合语音片段,让语音芯片一定逻辑播放语音提示信息。搭建并调试了电路,结果表明,该系统能准确的进行语音报站。

Impact of bus rapid transit on housing price and accessibility changes in Sydney: A repeat sales approach

ABSTRACT

New public transport infrastructure is expected to improve accessibility for local residents, and thus contribute to increased land value. The contribution that a bus rapid transit (BRT) system can make to increased land value is less certain than for rail-based systems, with the literature mostly containing bus-based examples from developing countries with extensive BRT networks. This article considers a BRT system named the Liverpool–Parramatta Transitway (LPT) that was implemented in southwestern Sydney in 2003 to improve public transport accessibility in the local area. A repeat sales model is constructed to investigate the impact of the LPT on residential housing prices and accessibility changes using repeat sales data from before and after the opening of the LPT. This identified little price difference between properties close to LPT stations and outside of the area that could be considered as affected by the LPT service coverage. This outcome is at variance with the theoretical underpinning of land value uplift and other empirical evidence relating to the LPT. Hedonic models using the same repeat sales data investigate the study area in more detail, stratifying the sample by housing type and by comparing separate before and after models. These research outcomes identify the extent to which the BRT system has an impact on local housing prices through accessibility improvements to the study area and provide a deeper understanding as to how the quantification of land value uplift from BRT represents one element of the wider economic benefits of a BRT system.
