Embodiment Construction

[0036] The invention relates to a method of characterizing the road conditions of a route traveled by at least one road user. Road condition, also known as road quality, is representative of the roughness of the road, which may be due to degradation such as holes, potholes, bumps, etc., or due to the construction of the road: paving stones, road markings, etc. lead to. According to the invention, the characterization method makes it possible to determine parameters representative of road conditions. For example, it may be a class defined in such a way that if the class is high, the road has a high roughness class (bad road), and if the class is low, the road has a low roughness class (good road).

[0037] A road user is understood to be a user of a vehicle that circulates on the road. It may in particular be a bicycle, a motor vehicle, a two-wheeled motor vehicle or any other similar means of transport.

[0038] The method according to the invention uses two sensors: a thre...

Abstract

The invention relates to a method for characterizing a road for at least one route traveled by at least one road user by means of sensors: a triaxial accelerometer (ACC) and a geographic position sensor (GPS). The method comprises a measurement step (MES) for ignoring (AFF) the effects related to the speed of the road user in order to determine vibrations due to the road roughness, and a measurement processing step of analyzing the vibrations thus determined in order to characterize the condition of the (CAR) road.

Description

technical field [0001] The present invention relates to the characterization of road conditions. [0002] Roads may appear rough, which in some cases may be due to degradation such as holes, potholes, bumps, and in others due to the construction of the road: paving stones, road markings, etc. of. This roughness has a strong influence on the comfort and safety of road users, especially for bicycles. [0003] For these road users, it is useful to determine which are the most comfortable and safest roads to adapt their routes to. [0004] It is also useful for public authorities (eg road maintenance operators) and public works companies to monitor road conditions and plan repair and / or maintenance work when required. In this case, information related to road characteristics may be related to information related to road traffic. Background technique [0005] Currently there are only two solutions for monitoring the quality level of road networks: qualitative recording or qua...
