The invention relates to the technical field of traffic emergency guidance, and discloses a traffic early warning device and an emergency guidance system, and the device comprises a data collection unit, a data processing unit, a congestion early warning unit, and a path guidance unit. Wherein the data acquisition unit is used for collecting historical congestion data, environmental data and real-time traffic data; the data processing unit is used for identifying a congestion risk road section and a congestion risk time period, and calculating a traffic index of each road section; the congestion early warning unit is used for performing congestion prediction and identifying a congestion road section and a congestion time period; the path guiding unit plans an alternative guiding path for each congested road section based on the digital map, and selects an emergency guiding path from the alternative guiding paths. According to the invention, the accuracy of congestion prediction is improved, and more scientific and effective detouring suggestions can be provided for vehicles.

    本发明涉及交通应急引导的技术领域,公开了一种交通预警装置及应急引导系统,该装置包括数据采集单元、数据处理单元、拥堵预警单元、路径引导单元;其中:数据采集单元用于收集历史拥堵数据、环境数据,以及实时交通数据;数据处理单元用于识别拥堵风险路段和拥堵风险时段,并计算每个路段的通行指标;拥堵预警单元用于进行拥堵预测,识别拥堵路段和拥堵时段;路径引导单元基于数字化地图为每一个拥堵路段规划备选引导路径,并从备选引导路径中选择应急引导路径。本发明提高了拥堵预测的准确性,并能为车辆提供更科学有效的绕行建议。
