Ubiquitous and socially-aware real-time urban computing platform

这项研究的目的是通过赋予加拿大城市居民权力，使他们在提高市政基础设施提供的服务质量方面发挥重要作用，从而促进可行的社区。这种基础设施的质量被认为是理所当然的，直到它以某种方式失败（例如，交通事故和车辆事故正在成为加拿大的“家庭”问题）。这使得民用基础设施的管理成为我们社会和经济新陈代谢的关键。该提案通过启用支持紧急疏散规划、交通拥堵管理和车辆事故管理应用的新型增值应用程序，促进了加拿大25个以上城市采用的无线城市愿景。拟议的平台探讨了“公民科学”的各个方面，城市居民使用他们的便携式设备报告民用基础设施状况的实时数据。该平台利用社交计算和网络学科的融合来收集和关联上下文和语义事件，以获得情境感知并提供最适合城市居民的实时服务，从而实现“所需即所得”的服务。使用市政无线网状网络将情景内容传输到城市总部，以提高其投资回报率。城市服务器利用城市居民之间的社会关系以及他们的实时上下文来过滤和聚合用户生成的情景内容。市政无线网络用于将情况知识传送回漫游在城市中的城市居民（在移动的城市居民的便携式设备上）。该平台还将研究如何使不同的自我响应者群体能够以连贯和敏捷的方式临时自我组织，以促成复杂的协作行为的出现。

This research aims at promoting viable communities through empowering residents of Canadian cities to take a vital part in enhancing the quality of service delivered out of municipal infrastructures. The quality of this infrastructure is taken for granted until it fails in some way (e.g., traffic congestions and vehicle incidents are becoming Canadian 'household' concerns). This makes the management of the civil infrastructure key to our societal and economical metabolism. This proposal contributes to the wireless cities vision, adopted in more than 25 Canadian cities, by enabling new types of value-added applications that supports emergency evacuation planning, traffic congestion management and vehicle incident management applications. The proposed platform explores aspects of "citizen science" where city residents use their portable devices to report real-time data of the civil infrastructure status. The platform exploits the convergence of social computing and networking disciplines for gathering and correlating contextual and semantic events to derive situational awareness and deliver real-time services that are most suited for city residents leading to "what you need is what you get" services. Situational content is transported to city headquarters using municipal wireless mesh networks to enhance their Return On Investment. City servers take advantage of the social relationships between city residents as well as their real-time contexts to filter and aggregate user-generated situational content. The municipal wireless network is used to transfer back situational knowledge to city residents roaming across the city (on their portable devices of mobile city residents). The platform will also study how to enable diverse groups of self-responders to self-organize temporarily in a coherent and agile manner to enable the emergence of complex collaborative behaviour.
