Extant Legal and Jurisdictional Constraints on Irish Coastal Management

The success of any coastal zone management policy is dependent on, among other things, effective legislation and its enforcement. This article examines some possible legal constraints on the implementation of an integrated coastal zone management policy in Ireland. An introduction to the existing legal framework is provided, and the inconsistencies and ambiguities related, in particular, to jurisdiction and area of responsibility are highlighted. In particular the effect of land ownership and property rights on coastal zone management are examined with reference to two popular resort beaches in County Donegal, Ireland. While a revision of the relevant legislation is desirable, it is probably unrealistic; however, powers are available to the various institutions involved in coastal management that are currently unused. These are reviewed and their potential to improve coastal zone management is discussed.     

城市公交停保基地综合规划设计构想

大城市土地稀缺、交通拥堵严重、用地条件复杂、环境要求较高等特点为公交场站的规划设计提出了更多的挑战和难题,本文通过调研目前的国内大型城市公交停保基地,结合杭州阮家桥公交停保基地的设计．以创造和谐、绿色的示范性公交停保基地为目标,从环境、交通、工艺、场站形象、节能环保等方面进行了综合规划设计的探索和构想。     

《珠海市城市绿道网总体规划(2010—2020)》解析

为落实《珠江三角洲绿道网总体规划纲要》的要求,珠海市制定了《珠海市城市绿道网总体规划(2010—2020)》(简称《规划》)。首先阐述了对绿道定义及分级的认识。然后,分析了珠海市独特的山水自然环境,提出绿道网规划建设应遵循的原则和理念,认为《规划》应坚持"三因""、三边"、"三不""、三化"的"四三"原则及"环山滨水、通廊串联、单元式使用"的规划理念。《规划》以区域绿道为依托,根据城市组团分布、生态格局、自然人文景观分布等,形成了"四纵、两横、二环、六岛"的绿道网空间结构,绿道长度达1 003.02 km。《规划》还将建设任务分年度、分辖区进行分解,以确保规划建设的可操作性。     

大型公共建筑与交通设施组合规划研究

大型公共建筑是城市中人流的集散点与交通枢纽,在其使用的过程中势必引起复杂繁忙的交通运输问题.在阐述大型公共建筑交通影响分析的基础上,本文区别对待对于大型公共建筑具有不同功能与作用的交通设施,并重点分述了不同交通设施与大型公共建筑的优化配置问题.目的是:将大型公共建筑和与之配套的交通设施组合规划成为一个有机整体,以期实现在保证大型公共建筑使用功能的前提下,安全合理地疏导交通.     

智能运货车程序设计

实现运货车智能化重要的一环是程序设计。文章通过对智能运货车分模块编程,实现车辆的感知、预测、定位、路由寻经、规划、控制等功能。规划模块是核心模块,根据实际情况做出车道线保持、超车、停止、左转、右转、泊车等行为决策,分别编写各行为的执行程序,决策时调用相应的程序,实现了智能运货车的程序设计。仿真结果显示该设计的效果良好。     

城市组团的轨道交通接驳线研究

城市外围组团快速发展,需要较大运量的接驳线快速衔接城市轨道交通资源,同时缓解组团内日益增长的交通压力。从接驳线的功能定位、规划条件、制式比选及衔接模式等方面进行分析,并以天津空港经济区为例进行较为系统的说明。中低运量的轨道交通系统和BRT(快速公交系统)均能满足接驳线的需求。接驳线的建设应在发挥现有公共交通能力的基础上进行充分论证,不宜过度超前;采用轨道交通系统时要处理好同既有轨道交通线网的关系。     

An autonomous system for maintenance scheduling data-rich complex infrastructure: Fusing the railways’ condition,planning and cost

National railways are typically large and complex systems. Their network infrastructure usually includes extended track sections, bridges, stations and other supporting assets. In recent years, railways have also become a data-rich environment.Railway infrastructure assets have a very long life, but inherently degrade. Interventions are necessary but they can cause lateness, damage and hazards. Every day, thousands of discrete maintenance jobs are scheduled according to time and urgency. Service disruption has a direct economic impact. Planning for maintenance can be complex, expensive and uncertain.Autonomous scheduling of maintenance jobs is essential. The design strategy of a novel integrated system for automatic job scheduling is presented; from concept formulation to the examination of the data to information transitional level interface, and at the decision making level. The underlying architecture configures high-level fusion of technical and business drivers; scheduling optimized intervention plans that factor-in cost impact and added value.A proof of concept demonstrator was developed to validate the system principle and to test algorithm functionality. It employs a dashboard for visualization of the system response and to present key information. Real track incident and inspection datasets were analyzed to raise degradation alarms that initiate the automatic scheduling of maintenance tasks. Optimum scheduling was realized through data analytics and job sequencing heuristic and genetic algorithms, taking into account specific cost & value inputs from comprehensive task cost modelling. Formal face validation was conducted with railway infrastructure specialists and stakeholders. The demonstrator structure was found fit for purpose with logical component relationships, offering further scope for research and commercial exploitation.     

渔船编队规划模型

船舶编队规划通常归属于线性规划，用单纯形法求解，但对渔船，可能因渔场资源的可捕获量与各渔船年捕获量不匹配，而导致无解。本文提出，对这类问题可以先用匈牙利法求解，以得到渔场资源可捕获量多或少于渔船年捕获量的信息。根据此信息可以处理单纯形法的约束方程组中等式和不等式的关系，从而求出使目标函数值为最小的解。     

城市轨道交通地下停车场的设计理念和探索

通过分析武汉市轨道交通中山北路停车场的控制性因素,提出停车场按一层地下结构设计、地面部分用于商业开发的设计理念,研究地下停车场的工艺、建筑规划、结构、消防、通风采光、作业方式、综合楼及出入场线的设计方法。工程实例表明,采用本方法可在满足停车场功能需求的前提下,提高土地利用附加值及经济效益。
