PFI:BIC: The Living Bridge: The Future of Smart, User-Centered Transportation Infrastructure

这种创新伙伴关系：来自新罕布什尔州大学的建设创新能力（PFI：BIC）项目专注于“生活桥梁”，它展示了智能，可持续，以用户为中心的交通基础设施的未来。桥梁为社会提供了如此基本的服务，以至于它们往往被视为理所当然。通常情况下，只有当桥梁必须以巨大的代价被意外地替换，或者更糟的是，失败时，它们才会引起公众的兴趣。“生活桥”项目将创造一个自我诊断、自我报告的“智能桥”，由当地的可再生能源潮汐能提供动力，将具有里程碑意义的纪念桥-一座横跨潮汐的皮斯卡塔夸河的垂直升降桥，行人通道连接新罕布什尔州的朴茨茅斯和缅因州的基特里-改造成一个供研究人员、工程师、科学家和整个社区使用的生活实验室。Living Bridge将通过在工作桥梁上创建一个孵化器平台，吸引传感器和可再生能源技术的创新者，研究人员可以现场测试和评估新兴技术的影响和有效性。Living Bridge还将作为一个社区平台，向市民介绍现场和该地区的创新，以及如何将可再生能源纳入桥梁设计，从而实现可持续的交通基础设施，其影响远远超出该地区。可持续的智能桥梁是发展成功的基础设施系统的关键要素。为了推进智能服务系统和清洁能源转换的状态，该项目团队将设计和部署一个结构和环境监测系统，为桥梁状况评估，交通管理和环境管理提供信息;推进可再生能源技术的应用;并激发公众对桥梁创新的兴趣。这个PFI：BIC项目是通过具有结构，机械和海洋工程，传感技术和社会科学专业知识的学术研究人员之间的合作伙伴关系实现的;具有仪器，数据采集，潮汐能转换专业知识的小企业;以及具有桥梁设计专业知识的国家机构。Living Bridge的技术领域包括结构健康监测、潮汐能转换与流体-结构相互作用测量、河口环境监测和外联通信。传感器将用于校准桥梁的三维分析结构有限元模型。该模型的预测结构响应将评估桥梁的实测结构响应是否可接受。安装在涡轮机部署平台上的仪器将测量涡轮机下游的湍流流入和修正尾流的时空结构。所得数据将包括用于流体-结构相互作用模型的涡轮机性能和载荷。部署的环境传感器将测量河口水质;野生动物威慑传感器将阻止鱼类进入涡轮机。在涡轮机部署之前和部署期间，将使用水听器和摄像机，以监测由于涡轮机的存在而引起的环境变化。外联工作将使桥梁数据，历史和有关新系统的信息可供公众和K-12教育工作者访问和理解，并通过安装在桥梁上的信息亭提供便利。公众意识将通过新罕布什尔州使用的调查方法进行评估。花岗岩州民意调查。牵头机构是新罕布什尔州大学（UNH）及其土木工程系、机械工程系、社会学系和海洋工程中心。主要的工业合作伙伴是一家大型企业，MacArtney水下技术集团公司。（Houston，TX）;及小型企业Lite Enterprises，Inc.（Nashua，NH）。 更广泛的合作伙伴是新罕布什尔州交通部、新罕布什尔州渔猎&部、新罕布什尔州港务局、新罕布什尔州海岸计划、朴茨茅斯市（新罕布什尔州）、可持续发展朴茨茅斯（非营利），缅因州交通部，美国海岸警卫队，阿彻/西部（马萨诸塞州坎顿，大型企业），帕森斯-布林克霍夫（曼彻斯特，新罕布什尔州，大型企业），UNH技术营，UNH基础设施和气候网络，UNH Leitzel数学，科学和工程教育中心，以及马萨诸塞州理工学院的Changing Places（一个联合建筑和媒体实验室联盟，位于马萨诸塞州剑桥）。

This Partnerships for Innovation: Building Innovation Capacity (PFI:BIC) project from the University of New Hampshire focuses on a "living bridge", which exemplifies the future of smart, sustainable, user-centered transportation infrastructure. Bridges deliver such a fundamental service to society that they are often taken for granted. Typically, bridges only stir the public's interest when they must unexpectedly be replaced at great cost, or, worse, fail. The Living Bridge project will create a self-diagnosing, self-reporting "smart bridge" powered by a local renewable energy source, tidal energy, by transforming the landmark Memorial Bridge--a vertical lift bridge over the tidal Piscataqua River, with pedestrian access connecting Portsmouth, New Hampshire to Kittery, Maine--into a living laboratory for researchers, engineers, scientists, and the community at large. The Living Bridge will engage innovators in sensor and renewable energy technology by creating an incubator platform on a working bridge, from which researchers can field test and evaluate the impact and effectiveness of emerging technologies. The Living Bridge will also serve as a community platform to educate citizens about innovations occurring at the site and in the region, and about how incorporating renewable energy into bridge design can lead to a sustainable transportation infrastructure with impact far beyond the region. Sustainable, smart bridges are key elements in developing a successful infrastructure system. To advance the state of smart service systems and clean energy conversion, this project team will design and deploy a structural and environmental monitoring system that provides information for bridge condition assessment, traffic management, and environmental stewardship; advances renewable energy technology application; and excites the general public about bridge innovations. This PFI:BIC project is enabled through partnerships between academic researchers with expertise in structural, mechanical and ocean engineering, sensing technology and social science; small businesses with expertise in instrumentation, data acquisition, tidal energy conversion; and state agencies with bridge design expertise. The Living Bridge technical areas are structural health monitoring, tidal energy conversion with fluid-structure interaction measurements, estuarine environmental monitoring, and outreach communication. Sensors will be used to calibrate a three-dimensional analytical structural finite element model of the bridge. The predicted structural response from this model will assess the measured structural response of the bridge as acceptable or not. Instruments installed on the turbine deployment platform will measure the spatio-temporal structure of the turbulent inflow and modified wake flow downstream of the turbine. Resulting data will include turbine performance and loads for use in fluid-structure interaction models. Deployed environmental sensors will measure estuarine water quality; wildlife deterrent sensors will deter fish from the turbine. Hydrophones and video cameras will be used before and during turbine deployment to monitor environmental changes due to turbine presence. Outreach efforts will make bridge data, history, and information about new systems accessible and understandable to the public and K-12 educators, facilitated by an information kiosk installed at the bridge. Public awareness will be assessed with survey methods used in the N.H. Granite State Poll. The lead institution is the University of New Hampshire (UNH) with its departments of Civil Engineering, Mechanical Engineering, and Sociology, and the Center for Ocean Engineering.
