Road smoothness evaluation method and system based on road surface deformation and actual vehicle speed
The invention relates to a road smoothness evaluation method and system based on road surface deformation and actual vehicle speed. The method comprises the following steps: acquiring a vibration state of a vehicle by using speed information, position information, vertical acceleration information and inclination angle information of the vehicle; based on the vibration state of the vehicle, acquiring a deformation type and a deformation degree of a road surface in a road section passed by the vehicle; and acquiring the actual vehicle speed of the vehicle through the deformation type and the deformation degree of the pavement, and evaluating the smoothness of the to-be-tested pavement based on the actual vehicle speed and the road design vehicle speed. The actual vehicle speed of a vehicle passing through a deformed road section can be obtained through the road surface deformation type and deformation degree information, the service performance of the to-be-tested pavement in the regularity aspect can be evaluated on the basis of the difference value between the actual vehicle speed and the road design vehicle speed, the traffic capacity of different road sections and the driving safety when the vehicle passes through the sections are reflected, the position of the bad road section influencing the driving safety is determined, and guidance is provided for pavement maintenance and traffic management.
本发明涉及基于路面变形与实际车速的道路平顺性评价方法和系统，包括以下步骤：利用车辆的速度信息、位置信息、竖向加速度信息和倾角信息获取车辆的振动状态；基于车辆的振动状态，获取车辆经过的路段中，路面的变形类型和变形程度；通过路面的变形类型和变形程度获得车辆的实际车速，基于实际车速和道路设计车速评价待测路面的平顺性。通过路面变形类型和变形程度信息能够获取车辆在通过变形路段时的实际车速，再基于实际车速和道路设计车速的差值，能够评价待测路面的在平顺性方面的服务性能，反映不同路段的通行能力和车辆通过时的行驶安全性，确定影响行驶安全性的不良路段位置，为路面养护和交通管理提供指导。
