AI Technical Summary

Problems solved by technology

The measurement of the above-mentioned measuring instruments is mainly used for the quality inspection after the road is completed or the road is repaired. It is difficult to detect the smoothness of the road after it is opened to traffic, and it is impossible to remind the driver that there is a bumpy road section.

Abstract

The invention discloses a road flatness calculation method and a system, and the method comprises the steps: collecting the driving data of a vehicle on a road, and the driving data comprise the driving speed of the vehicle and the gravitational acceleration of the vehicle; preprocessing the driving data to obtain a target gravitational acceleration; and based on a preset flatness calculation formula, calculating according to the target gravitational acceleration to obtain a road flatness coefficient. According to the method, the flatness of a road after traffic is measured, and a driver is reminded to effectively avoid a bumpy road section.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a calculation method and system for road roughness. Background technique [0002] Road roughness has a certain relationship with the leveling conditions of each structural level of the road, that is, the leveling effect of each level will be reflected on the road surface cumulatively. The flatness test is a prescribed standard gauge, which measures the unevenness of the road surface intermittently or continuously, that is, the index of the flatness, and is also an important link in the acceptance and maintenance of the road surface. [0003] Existing road roughness measurements are mainly carried out by the following techniques: three-meter ruler measurement method, eight-wheel continuous flatness meter measurement, vehicle-mounted bump accumulator flatness test method, and laser flatness tester measurement. For example, in the quality assessment of road construction, laser flat...
