The invention belongs to the technical field of automobile auxiliary driving, and discloses an expressway safety situation evaluation method and system. The expressway safety situation evaluation system comprises a vehicle information acquisition module, a positioning module, a highway section information acquisition module, a central control module, an image acquisition module, an image analysismodule, a congestion degree judgment module, a vehicle speed constant module, a surrounding vehicle speed presumption module, a ground obstacle detection module, a safety evaluation module, a data storage module and a display module. The lane number, the lane width, the speed limiting information and the forbidding information of an expressway can be acquired through the expressway section information acquisition, and the overall information of a specific expressway section is mastered; through the arrangement of the congestion degree judgment module, the judgment of the congestion degree of vehicles on the expressway section is realized, and the speed of surrounding vehicles is estimated through a constant speed, so that the speed information of overspeed vehicles is obtained, and the safety evaluation is more accurate.
本发明属于汽车辅助驾驶技术领域,公开了一种高速公路安全态势评估方法及评估系统,所述高速公路安全态势评估系统包括:车辆信息获取模块、定位模块、高速路段信息获取模块、中央控制模块、图像采集模块、图像分析模块、拥挤度判定模块、车速恒定模块、周边车辆车速推定模块、地面障碍物探测模块、安全评估模块、数据存储模块、显示模块。本发明通过高速路段信息获取能够实现对高速公路的车道条数、车道宽度、限速信息、禁止信息进行获取,实现对高速公路特定路段的整体信息的把握;通过拥挤度判定模块的设置实现对高速路段车辆拥挤度的判定,并通过恒定车速推定周边车辆车速,实现对超速车辆的车速信息的获取,进行安全评估更准确。
