The invention relates to a method for estimating an international roughness index (IRI) of a road or a road segment, said method comprising a preliminary step (1) and an international roughness index estimation step (10). The preliminary step (1) comprises: collecting (2) values of damping and stiffness coefficients (Ct, Kt) of the vehicle tires; and collecting (3) vehicle vertical acceleration values (Azvehile) measured on a vehicle driven at a constant rate along a road segment associated with a known international roughness index value or a known road profile, and vehicle geo-reference data and indications with the measured vertical acceleration values (Azvehile) associated rate data for a given constant rate.
本发明涉及用于估计道路或道路段的国际粗糙度指标(IRI)的方法,所述方法包括初步步骤(1)和国际粗糙度指标估计步骤(10)。初步步骤(1)包括:收集(2)运载工具轮胎阻尼系数和刚度系数(Ct、Kt)的值;以及收集(3):在沿着已知的国际粗糙度指标值或已知的道路简档(profiler)所关联的道路段以恒定速率驾驶的运载工具上测量的运载工具垂直加速度值(Azvehicle)、以及运载工具地理参考数据和指示与所测量的垂直加速度值(Azvehicle)相关联的给定恒定速率的速率数据。
