提出了1个经济可运作的实时动态节能减碳计算模型,用KPI来评估节能减碳效果,运作方式如下:配备GPS装置之实验车,后端软件自动动态搭配Google Map与路径图资之起讫点(A→B)来回一趟,才量该车之耗油量,由行前预估值、旅行时间、动态交通事件与实际油耗值之误差分析,在实时交通信息协助下选定之KPI (key performance index)值(含油耗、CO2排放量、道路等级、旅行时间及ETC (electronic toll collection)费用等)做比较.搜集对应环保路径之路网交通信息数据及交通信息建立历史数据库,配合时速/油耗表完成油耗/碳排放系统数据库,得出实时交通信息占比与油耗预估误差率关系图. 相似文献

面对铁路智能化和未来演进,现有的移动通信技术不能满足智能铁路大容量数据传输,铁路亟需新一代移动通信支撑。5G技术可全面推进铁路通信技术换代升级,但对于数量庞大、高速移动用户,时速350 km上行多普勒频偏高于2 kHz,如不能有效预估并补偿,系统解调性能会严重恶化。针对5G移动通信在智能铁路的应用中面临的问题,分析其业务指标;提出了智能铁路5G移动通信整体架构;并对区间、隧道、室内覆盖组网进行了规划,描述了多普勒频偏原理并给出了频偏补偿方法,这可为实现智能铁路提供技术支持。 相似文献

AbstractThe aim of this paper is to measure ‘overall’ success of a public private partnership (PPP) transport projects using four case studies. All four case studies are PPP toll roads from four different EU countries (UK, Spain, Portugal and Greece). The case studies have been analysed using a manual Qualitative Comparative Analysis approach. According to the paper, three different perspectives have been used to measure the success of a project, that is, project management perspective, stakeholder perspective and contract management perspective. The ‘overall’ success has then been deduced by bringing these three perspectives together as a holistic approach. The findings are presented in the form of a matrix and the final outcome of the paper shows a simple methodological approach that can be used to measure success of a PPP transport project. Since the study takes more of a qualitative approach, researcher bias and perceptions have a major role to play in the final outcome. However, to reduce ‘biasness’, quantitative measures have also been used to quantify the Key Performance Indicators and performance measures in the case studies. It is hoped that the study makes a valid contribution to the areas of transport PPPs and performance measurement. 相似文献
