项目摘要

This project aims to radically transform traffic management, emergency response, and urban planning practices via predictive analytics on rich data streams from increasingly prevalent instrumented and connected vehicles, infrastructure, and people. Road safety and congestion are a formidable challenge for communities. Current incident management practices are largely reactive in response to road user reports. With the outcome of this project, cities could proactively deploy assets and manage traffic. This would reduce emergency response times, saving lives, and minimizing disruptions to traffic. Efforts are planned in Kindergarten-12 outreach, undergraduate education, outreach to women and minority students, and incorporation of the research into courses, with the goal to inspire and train a diverse cohort for the next-generation of scientists and prepare them for taking on challenges arising from smart and connected communities. To realize the envisioned system, an integrated research approach is taken to tackle the following closely related research tasks: (1) integration of heterogeneous data streams using a new sparse multi-task multi-view feature fusing method; (2) prediction of traffic incidents by designing a novel high-order low-rank model; (3) teaming of connected vehicles and roadside sensor systems; (4) verification of traffic condition prediction by crowdsourcing the ground truth from user reports in real-time; (5) selection of crowdsourcing participants that recruits and selects voluntary operators of instrumented connected vehicles to provide onboard sensing readings; (6) selection of high quality and diverse images and videos from crowdsourcing vehicles to provide better data for traffic prediction; and 7) design of optimal rerouting strategies to improve commuters' routes in the time of potential traffic disruption.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目旨在通过对来自日益流行的仪表化和互联车辆、基础设施和人员的丰富数据流进行预测分析，从根本上改变交通管理、应急响应和城市规划实践。道路安全和拥堵是社区面临的巨大挑战。当前的事故管理实践很大程度上是对道路使用者报告的反应。通过该项目的成果，城市可以主动部署资产并管理交通。这将减少紧急响应时间、拯救生命并最大限度地减少交通中断。计划在幼儿园 12 年级的外展、本科教育、对女性和少数族裔学生的外展以及将研究纳入课程方面做出努力，目的是激励和培训下一代科学家的多元化群体，并为他们应对智能和互联社区带来的挑战做好准备。为了实现设想的系统，采用集成研究方法来解决以下密切相关的研究任务：（1）使用新的稀疏多任务多视图特征融合方法集成异构数据流； (2)通过设计新颖的高阶低秩模型来预测交通事件； (3) 联网车辆和路边传感器系统的组合；（4）通过众包实时用户报告中的真实数据来验证交通状况预测； (5) 选择众包参与者，招募和选择自愿的仪表联网车辆操作员来提供车载传感读数；（6）从众包车辆中选取高质量、多样化的图像和视频，为交通预测提供更好的数据； 7) 设计最佳改道策略，以在潜在交通中断时改善通勤者的路线。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
