Abstract

The invention provides a method and system for collecting road flatness, an evaluation system, a medium and a server. The method comprises: receiving acceleration information in three dimension directions, vehicle driving speed information, a vehicle real-time coordinate position, and a vehicle sprung parameter of a vehicle driving on a road; according to the acceleration information, the vehicledriving speed information, and the vehicle sprung parameter, calculating a flatness index of the road; and matching the road flatness index with the vehicle real-time coordinate position according toa time sequence. According to the invention, the road management department can obtain the flatness condition of the road network comprehensively in real time; for the same road section, the detectionaccuracy and reliability can be improved continuously with increasing of the detection number of times; the road surface flatness detection cost can be lowered to the greatest extent; and the flatness detection cycle can be reduced.

Description

technical field [0001] The invention belongs to the technical field of road engineering detection, and relates to a collection method / system, in particular to a road roughness collection method / system, an evaluation system, a medium and a server. Background technique [0002] my country has gradually changed from a period of large-scale road construction to a period of large-scale road maintenance. As the core part of the road maintenance management system, the detection and evaluation of pavement quality is one of the most important topics at present. Studies have shown that road surface roughness accounts for 40%-60% of the total score of the pavement service index. At present, my country mainly evaluates road surface roughness through the international roughness index IRI. The higher the IRI value of the pavement, the worse the smoothness of the pavement. The poor pavement will not only affect the driving safety of the road, reduce the driving comfort, increase the operat...
