Ubiquitous and participatory social networking for ambient situational awareness

该提案通过允许城市居民有机会通过个人观点的集合来协作发展集体情境意识，从而促进可行的社区。这项建议的重点是使加拿大城市居民能够在提高市政基础设施提供的服务质量方面发挥重要作用，特别是在紧急情况等真实的生活事件中。我们认为这个基础设施的质量是理所当然的，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。在该平台中，城市居民使用他们的移动的设备来报告基础设施状态信息;这需要为所考虑的应用部署最少的传感器。使用市政无线网状网络（WMN）将情景内容传输到城市总部，以提高其ROI。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物理位置来过滤和聚合用户生成的情景内容。WMN用于将情景知识传输回漫游在城市中的城市居民（在他们的便携式设备上）。在时间要求更高的应用中，例如事件管理、情境信息（例如，事故通知）可以在覆盖高速公路的WMN上涟漪，通知行驶的汽车并转移交通以避免车辆聚集。此外，城市居民可以查询数据库并准确及时地定位实时紧急信息，无论他们身在何处（例如，疏散时间安排和到最近的安全避难所的目的地选择）。该平台利用了社会计算和网络学科的融合，并依赖于整合市政基础设施和城市居民之间社会关系的结构。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。

This proposal promotes viable communities through allowing City residents the opportunity to collaboratively develop a collective situational awareness through an assembly of individual perspectives. This proposal focuses on empowering residents of Canadian cities to take a vital part in enhancing the quality of service delivered out of municipal infrastructures especially during real life events such as emergencies. We take the quality of this infrastructure 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. In the platform, city residents use their mobile devices to report infrastructure status information; this requires minimal deployment of sensors for the applications considered. Situational content is transported to city headquarters using municipal wireless mesh networks (WMN) to enhance their ROI. City servers take advantage of the social relationships between city residents as well as their real-time physical location to filter and aggregate user-generated situational content. The WMN is used to transfer back situational knowledge to city residents (on their portable devices) roaming across the city. In more time critical applications, such as incident management, situational information (e.g., incident notifications) may ripple across the WMN covering highways notifying travelling cars and diverting traffic to avoid vehicle build up. In addition, City residents may query databases and locate real-time emergency information in an accurate and timely no matter where they are (e.g., evacuation scheduling and destination choice to the nearest safe shelters). The platform exploits the convergence of social computing and networking disciplines and relies on constructs that integrate features of municipal infrastructure and social relationships among city residents. 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.
