Abstract:
An experimental trailer-mounted instrumentation system which surveys and records data on the roadway topography while being towed at normal highway speeds has been developed and tested. The system uses non-contacting electro-optical sensors to measure the relative height of the roadway surface along 12 selected paths which are spaced at intervals across the 12-ft. width of a normal traffic lane.
