Advanced measuring equipment for cost-effective maintenance planning

Greenwood Engineering develops and manufactures advanced equipment for pavement condition measurements in the global road sector. All systems are designed to suit research level as well as routine survey operations. All system design and software are made in-house allowing for customized modules to be created to assure data continuity for the road administrations.

Traffic Speed Deflectometer (TSD)

The Traffic Speed Deflectometer (TSD), is an innovative Rolling Wheel Deflectometer measuring pavement response to applied load. The unique TSD technology is developed by Greenwood Engineering and has initiated a shift of paradigm in pavement engineering worldwide.

The Greenwood TSD provides continuous bearing capacity results at project and network level while following the flow of traffic. This makes the Greenwood TSD highly cost-effective.


The Profiler, also known as a profiler – is an advanced and accurate piece of equipment for pavement profile measurements. Subsystems, such as Right-of-way Imaging (ROW) and Surface Imaging System (SIS), can be added and synchronized with the profile data.


The LaserProf is a compact and portable profiler which can be mounted on a standard tow hitch. It can have one or two laser sensors and is designed to be a tool for the pavement supervision engineer making quality control before and after paving. The LaserProf has been implemented in the LaserProf BikeLaneTrailer for measuring bike lanes. GPS and Right-of-Way (ROW) can be added to the LaserProf.

Road Marking Vehicle (RMV)

The Road Marking Vehicle (RMV) is an advanced integrated vehicle for measurements of road lane marking parameters. Our high-tech sensors and cameras precisely measure and evaluate road lane markings, to ensure that our roads remain safe and well-maintained.

The Road Marking Vehicle integrates Delta’s LTL-M sensor for mobile retro-reflection measurements with Greenwood’s own developed systems for laser surface measurements, high-quality Surface Imaging System (SIS), front looking Right of Way imaging, all started from one single software application. Accompanying the RMV is a software stack of post-processing applications which use intelligent Computer Vision algorithms to automatically extract coverage, length, width and more, from the SIS images. Further, linear regression models can be included in data exports to, e.g. deliver, wet retro-reflection, friction, daylight brightness (Qd) and more.


Greenwood´s Bikelanetrailer provides a longitudinal profile, which optimizes management of bikelane and paths maintenance, and is used for condition surveys. The Bikelanetrailer uses high precision sensors and digital data acquisition for highest possible measurement quality and can be towered by a scooter or a standard car as well.

Manage traffic sign inventory the easiest way

Greenwood Engineering´s AI – Inventory Detection system detects traffic signs, reflective poles, traffic lights and crash barriers via front-facing cameras and gives each asset a GPS coordinate. This automatically generates a map of the location of each asset as well as an image.

The software, which is developed by Greenwood Engineering, utilizes state-of-the-art machine learning algorithms and large quantities of image data.

Greenwood Engineering customizes the equipment to suit your requirements and can be retrofitted to a Traffic Speed Deflectometer (TSD), Profiler or other vehicles.
