深圳北站综合交通枢纽出租车接驳方案研究

深圳北站是深圳市在建的大型综合交通枢纽,出租车接驳设施的规划设计是该枢纽的难点之一。依据现有建设条件及出租车场站与国铁、城市轨道交通、道路公交、广场及周边道路等的接驳关系及出租车场站方案布局难点,提出出租车接驳设施规划的理念与思路。在对枢纽出租车场站相关的各类人流与车流特点分析的基础上,通过两层及三层方案的比选,提出出租车场站三层立体布局的接驳方案。同时对出租车上客区的布局方式进行4个不同方案的比选。推荐采用矩阵式出租车上客布局方案。     

美国《公共交通安全标准纲要》中城市轨道交通安全标准法规体系结构及其启示

介绍了美国联邦政府通过立法发布的《公共交通安全标准纲要》。该纲要定义了城市轨道交通模式及其安全标准。城市轨道交通安全标准分为车辆、基础设施、运营和人员等标准,共128项,以技术对象层次分为类、子类和子功能类等3层。标准类型分为法规、标准和规范。线路、通信信号、车辆设备和运营规章程序标准是安全标准的主体。解析了采用标准的法规,举例说明了安全法规采用标准。我国城市轨道交通当务之急是研究建立安全标准体系。     

基于美国规范的机场高架桥抗震分析

在美国规范下,为研究机场站前高架桥的地震反应性能,分析桥梁下部结构的影响,达到指导高架桥设计的目的,以某东南亚机场高架桥为研究对象,利用有限元软件建立三维模型,分析其非常规墩柱尺寸对整体桥梁结构地震反应的影响,并对桥梁进行延性抗震设计验算。结果表明：采用上大下小的变截面圆柱墩,主梁采用宽度为32.8 m的整体式箱梁,通过验算控制截面,得出墩底是较为薄弱的截面。其内容可为其它类似桥梁抗震工程提供借鉴。

美国旅游公路发展及对我国的启示

为寻求我国旅游公路的合理发展途径,结合现阶段对我国旅游公路内涵、结构及功能的理 解,通过对美国旅游公路发展背景的研究,为我国旅游公路体系的构建提供借鉴与经验。分析了 美国旅游公路自20 世纪60 年代至今的发展历程与发展成效,认为旅游公路的发展成为其交通行 业的新发展点,诞生了公路旅游知名品牌,为复兴沿线经济提供了主要条件。同时根据我国旅游 公路发展的基本情况与现存问题,以满足社会经济发展及人民精神生活需求为出发点,比较我国 与美国旅游公路的发展特征,分析我国开展旅游公路规划建设的可行性与必要性,认为我国现阶 段与美国开展国家层面旅游公路体系构建的初始阶段面临的时机、发展环境及建设价值均具有相 似性,我国也具备较为充分的发展条件。并在我国现行体制基础上,提出建立我国旅游公路体系 的具体建议,包括建立评估认定机制,推行区域旅游公路规划,建立建设标准、管理机制,研究 投融资政策,以及整体构建我国旅游公路体系的最终目标。     

Implementation of sustainable urban transport in Latin America

Transportation provides vital support to the economic and social development of Latin America cities, but current growth patterns and trends are not sustainable. While non-motorized and public transport modes have the largest shares in passenger transport, there is a strong increase in ownership and use of cars and motorcycles. In Latin America in 2010 there were 2.5 new motor vehicle registrations for every new child being born.     

Coastal Hazards and the Built Environment on Barrier Islands: A Retrospective View of Nags Head n the Late 1990s

This article provides a summary of past disasters, and hazard mitigation initiatives in the state of North Carolina, with a focus on the barrier island of Nags Head. The article also highlights the application of GIS technology to assess (i) the built environment and the extent of development and tax base in the "danger" zones (floods, oceanfront hazard zone, incipient inlets); (ii) the status of pre-Flood Insurance Rate Mapping (FlRM) structures on developed parcels; and (iii) vacant land in relation to current zoning. Findings show that 72% of Nags Head was developed, with close to one-third of the developed parcels within the oceanfront hazard zone. A relatively high percentage of structures built prior to Nags Head's regular participation in the Flood Insurance Rate Mapping (FIRM) program also lie within incipient inlets and VE flood zones. These findings were used as part of Nags Head's ongoing hazard mitigation initiatives.     

Campus parking supply impacts on transportation mode choice

Parking demand is a significant land-use problem in campus planning. The parking policies of universities and large corporations with facilities located in small urban areas shape the character of their campuses. These facilities will benefit from a simplified methodology to study the effects of parking availability on transportation mode mix and impacts on recruitment and staffing policies. This paper, based on a case study of North Dakota State University in the United States, introduces an analytical framework to provide planners with insights about how parking supply and demand affects campus transportation mode choice. The methodology relies only on aggregate mode choice data for the special generator zone and the average aggregate volume/capacity ratio projections for all external routes that access the zone. This reduced data requirement significantly lowers analysis cost and obviates the need for specialized modelling software and spatial network analysis tools. Results illustrate that the framework is effective for analysing mode choice changes under different scenarios of parking supply and population growth.
