ROAD MONITORING METHOD AND SYSTEM

This invention relates to a method 20 and system 10 for monitoring road condition, by providing, for a portion (14.1 to 14.m) of a road 12, an approximation 210 of a roughness figure in accordance with a roughness index. The method 10 comprises receiving speed data 208 of a first vehicle 16 travelli...

Beschreibung
Zusammenfassung:	This invention relates to a method 20 and system 10 for monitoring road condition, by providing, for a portion (14.1 to 14.m) of a road 12, an approximation 210 of a roughness figure in accordance with a roughness index. The method 10 comprises receiving speed data 208 of a first vehicle 16 travelling along each of the portions 14.1 to 14.m of the road 12 and receiving, from a measuring device 18 carried on the first vehicle 16, measured acceleration data 204 of the device 18 perpendicular to the road 12 surface. The acceleration data 204 is processed to provide a parameter value 206 relating to the acceleration data 204 for each of the portions 14.1 to 14.m of the road 12. A first speed-based conversion equation and the speed data 208 is utilised to convert said parameter 206 into the approximation 210 of a roughness figure for each of the portions 14.1 to 14.m of the road 12, in accordance with the roughness index.
