A HIGH SPEED ROAD CONDITION DATA COLLECTION SYSTEM FOR LOW COST ROADS

A modular system for road condition data collection has been devised suitable for use on both heavily trafficked and low cost roads. It is built about a data base mounted in a laptop computer which is situated in the survey vehicle. To date road roughness in terms of IRI may be measured automatically with a Vehicle Mounted Bump Integrator. In addition near side wheel path rutting may be assessed at normal traffic speeds, to within 2 mm, by the use of cheap ultrasonic transducers. A crack assessment module is under research and development and whilst real time processing is not yet possible the necessary algorithms for use with both serial and parallel computing architectures are available and have been widely used with analysis times of less than a second for each image of the road's surface obtained.
