摘要

交通态势感知是智能交通系统的重要研究方向。已有研究大多关注如何使用物理传感器感知当下交通态势并预测未来交通状况。然而，物理传感器性能易因天气影响、电磁干扰、能源限制等问题出现不稳定或失效情况，导致其采集的数据稀疏或缺失，使其对交通态势感知滞后且不准确。社会媒体数据为及时感知完善的交通态势信息提供了新的增强方式。面向当下异常交通情况频发的城市交通管控现状，社会传感与物理传感数据互为补充，可进一步满足城市交通高效管理需求。基于此，对基于社会媒体数据的交通事件检测和交通状况预测工作展开分析研究，探讨社会媒体数据增强的交通态势感知研究工作如何为交通管理部门提供决策支持，以合理规划、引导交通，缓解交通拥堵，最后提出社会媒体数据增强的交通态势感知还需进一步探索的方向。

Abstract

Traffic situational awareness is an important research direction of intelligent transportation systems.Most of the existing research focused on how to use physical sensors to perceive the current traffic situation and predict the future traffic state.However

the performance of physical sensors is prone to instability or failure due to adverse weather

electromagnetic interference

energy limitation and other problems

resulting in sparse or missing collected data

which makes the perception of traffic situation lagging and inaccurate.Social media data provides a new and enhanced way of perceiving comprehensive traffic situation information in a timely manner.Facing with the current traffic situation where sudden abnormal traffic events occur frequently

social sensing and physical sensing data can complement with each other to further improve the efficiency of urban traffic management.The related work of traffic event detection and traffic state prediction enhancing based on social media data were analyzed

and how those research works provide decision support for the traffic management departments to plan and guide traffic reasonably and alleviate traffic congestion were explored.Finally

some future research directions of traffic situational awareness enhanced by social media data were proposed.
