CPS:Small: Transforming a City's Transportation Infrastructure through an Embedded Pervasive Communication Network

CPS：小号：通过嵌入式普适通信网络改造城市交通基础设施该奖项由2009年美国复苏和再投资法案资助（公法111-5）。这项跨学科研究的目标是开发新技术，将城市街道改造成混合交通/通信系统，称为智能道路（iRoad），其中自主无线设备与交通信号共处一处，以形成无线网络，该网络融合来自整个城市的实时交通数据，从而使广泛的新应用成为可能。该方法是通过分布式队列管理、自适应速率控制和多层信任，在普适无线平台上建立新的定量带宽分配、速率/延迟保证和位置相关安全能力。这些新的能力导致运输监测和控制职能的设计和运作方式发生根本性变化。 iRoad系统所面临的许多技术挑战是开放性问题。在这个项目中开发的新理论/协议将支持复杂的带宽管理，服务质量，多层信任和信息融合在一个苛刻的环境中，关键的运输功能的实施。解决这些基本问题将推动无线技术和交通工程领域的发展。研究成果有可能广泛应用于其他无线系统。 在该国正在使其破旧的交通基础设施现代化之际，iRoad系统的经济和社会影响是巨大的。它提供了一个无处不在的通信基础设施和工程框架，以建立新的应用程序，如实时交通地图，在线最佳路线查询，智能节能汽车等研究成果将通过课程材料，学术出版物，行业连接和在当地交通部门的演示文稿进行传播。

CPS: Small: Transforming a City's Transportation Infrastructure through an Embedded Pervasive Communication NetworkThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The objective of this inter-disciplinary research is to develop new technologies to transform the streets of a city into a hybrid transportation/communication system, called the Intelligent Road (iRoad), where autonomous wireless devices are co-located with traffic signals to form a wireless network that fuses real-time transportation data from all over the city to make a wide range of new applications possible. The approach is to build new capacities of quantitative bandwidth distribution, rate/delay assurance, and location-dependent security on a pervasive wireless platform through distributed queue management, adaptive rate control, and multi-layered trust. These new capacities lead to transformative changes in the way the transportation monitoring and control functions are designed and operated. Many technical challenges faced by the iRoad system are open problems. New theories/protocols developed in this project will support sophisticated bandwidth management, quality of service, multi-layered trust, and information fusion in a demanding environment where critical transportation functions are implemented. Solving these fundamental problems advances the state of the art in both wireless technologies and transportation engineering. The research outcome is likely to be broadly applicable in other wireless systems. The economic and societal impact of the iRoad system is tremendous at a time when the country is modernizing its ailing transportation infrastructure. It provides a pervasive communication infrastructure and engineering framework to build new applications such as real-time traffic map, online best-route query, intelligent fuel-efficient vehicles, etc. The research results will be disseminated through course materials, academic publication, industry connection, and presentations at the local transportation department.
