川道型城市构建轨道交通概念线网研究

川道型城市分布于丘陵沟壑之内,其城市轨道交通网络不可能像平原型城市那样以"面"形向四周扩展布局。通过对川道型城市的区域特征分析,总结出居民出行总体呈现"横向聚集、轴向交流"的特征,通过"线"形沿川道主轴布线,以川道断面客流测试轨道交通线路数量,根据组团连接关系拆分组合线路,形成川道型城市的概念线网,最后以西宁市轨道交通概念线网的构建作为示例,为今后川道型城市轨道交通线网布局提供借鉴。     

二线城市轨道交通发展浅思

针对国内各个地铁建设城市的规模、人口对城市等级进行分类,并将无锡纳入二线城市。总结分析二线城市轨道交通的发展经验,分析无锡城市轨道交通发展现状和初期客流规模较小等特征。提出线网层面不同编组、制式车辆的互联互通和提升轨道交通客流的一些建议和举措,为二线城市的轨道交通可持续发展提供启示。     

都市圈内中小城市轨道交通发展战略探讨

在都市圈发展趋势下,重视圈内核心城市轨道交通发展的同时,中小城市的轨道交通发展客观上已提上日程。分析都市圈发展给中小城市发展带来的机遇,以及都市圈内中小城市发展轨道交通的必要性。以资阳市为例,分析成都都市圈背景下资阳市的区位特征、城市发展理念和交通发展战略,提出适合资阳市的轨道交通发展战略和"区域+市区"的轨道发展模式,为资阳市与成都市同城化发展、融入成都都市圈、提升城市品质奠定基础。     

中小城市提高公交吸引力的措施

目前,中小城市公共汽车交通存在着网络密度低、运行密度慢、基础设施落后等问题,致使人们乘公共汽车出门的比例不高。为解决城市交通拥堵,实现中小城市公共交通的可持续发展,应当采取多项措施,将中小城市居民的出行方式转移到公共交通上来。     

Eco-design of transportation in sustainable supply chain management: A DEA-like method

This study addresses the issue of eco-design for transportation in sustainable supply chain management (SSCM). Data envelopment analysis (DEA) is adopted and extended to construct a model for this application. This proposed model, together with the tractable algorithm developed in this research, can provide stakeholders with a Pareto Optimal transportation strategy. This derived transportation strategy can help stakeholders realize certain transportation goals with less resource consumption and pollution emission. The discussion presented leads to a heuristic Joint Transportation Policy and concludes with two useful suggestions for putting the strategy into practice. The proposed model was used in an empirical study of design sustainable transportation mechanism for one air-condition manufacturer in China to transport its products as well, the analysis further demonstrating the theoretical and practical value of this research.     

Restricted car-use and perceived accessibility

In order to plan for, and achieve, a sustainable and accessible transport system, research and policies alike recognize a need to implement and enhance alternative transport options in favor of the private car. Moreover, these sustainable alternatives need to offer sufficient levels of accessibility regardless of where people live or work. We present and discuss an approach for capturing and evaluating perceived accessibility, with the ability to differentiate between individuals. Levels of perceived accessibility are compared before and after a fictive car use restriction, and between residential areas, using data from 2711 residents of Malmö, Sweden. A main conclusion is that levels of perceived accessibility become significantly lower for car users when they are limited in their options for daily travel. The difference is more substantive for frequent car users, who already travel less by sustainable modes today. There are also significant differences in levels of perceived accessibility in the restricted scenario, depending on where individuals live. These novel findings may not come as a surprise, but they emphasize the importance of including and analyzing perceptions of car users when designing accessible and sustainable transport systems. The paper ends with a discussion on how to facilitate the transition from current transport systems to an inclusive and accessible system.     

Sustainable urban futures from transportation and planning to networked urban mobilities

When discussing the future of cities, there is a tendency to focus on technology that will make cities and mobilities more sustainable. A bit further down the line the question of understanding or changing everyday practice arises – how to get people to transform their current mobility practice, or to adjust to the technologies introduced. As a key to understanding and changing practice I argue that storytelling plays a crucial role on different scales. In line with this, the concept of structural stories can be used to understand how specific framings of modes of transport guides everyday practices. To illustrate this, I will use the example of a concept of redesigning Copenhagen’s streets. On these streets space is redistributed so that pedestrians, cyclists and busses get more space, and more space is created for public places and city life. Consequently, the space allocated for cars and parking is scaled down.     

城市可持续交通系统的实现方法

以沈阳市为例,采用SWOT法研究建立可持续交通发展的战略组合,在此基础上,借助于交通战略、规划、政策、法规等手段,充分协调土地利用与交通系统、不同的交通方式、交通规划建设与交通管理、交通发展与环境保护、交通发展与资源投入之间的关系,达到既要满足现在的交通需求,又不损坏未来满足不断发展的交通需求的能力,实现经济、社会、环境的可持续发展以及交通系统自身的可持续发展的目的。     

做好大学生党员发展工作要把住"五关"

高校在对大学生进行专业知识传授时,努力把他们培养成政治上积极要求进步的合格人才,这既是学校党建工作的一项重要内容,又是适应地方经济发展需要、实现可持续发展的一个重要方面。     

调结构 稳出口 保持摩托车外贸可持续发展

我国摩托车工业已经取得了一定的成绩，尤其在近几年已经实现了一系列战略转变，但在金融危机的影响下，摩托车出口面临了严峻的挑战，在这种情况下，只有调结构、稳出口，才能保持摩托车外贸可持续发展。
