Laser Measure Deflectometer (LMD)
The LMD is a new traffic speed structural pavement survey device developed by GeoSolve for screening road networks at network level. The LMD consists of a MEASURE TSDD Gen5 device mounted to a short (2 to 3 axle) wheelbase truck, enabling access to winding rural and constrained urban roads. It can also survey at any time of the year, particularly in winter-spring periods, when the pavement is at its most critical condition, unlike alternative laser-based solutions which require fine weather for testing.
GeoSolve has a number of presentations and published papers on the LMD.
An introduction presentation to the LMD can be found here. If you are interested in the full presentation, please contact Stephen Wormald.
