Christian Glantz

Christian Glantz works as a Research Engineer within the Operations and Maintenance unit. He holds a Master of Science in Engineering degree in Civil Engineering from Lund University Faculty of Engineering and has since worked with road surface measurements and road condition surveys.

Christian’s research primarily focuses on issues related to the maintenance of roads and streets. In this work, VTI’s measurement vehicle, the Mobile Research Platform (MRP), is an important tool for collecting detailed information about the condition of road surfaces and surrounding road environments. The research is conducted with the aim of describing the strengths and weaknesses of roads, enabling road authorities to make informed decisions regarding when maintenance is required and which measures are most appropriate.

Collecting large amounts of road data is relatively straightforward, but the important part is being able to interpret the measurement values and relate them to the road’s deficiencies and strengths. There are still shortcomings within the road network that need to be measured and explained more effectively, which in the long term would support better socio-economic decision-making.”

The focus of the work includes:

• Measurement of road surface condition and development of parameters describing it.
• Analysis and interpretation of road surface data to describe functional and technical condition.
• Revision and development of new methodological descriptions.

From data to understanding

Christian’s motivation in research is to continuously improve and refine the results collected by the measurement vehicle. The large volume of data must be sufficiently accurate while also describing the characteristics of the road in a way that reflects the actual problem. Understanding the relationship between pavement engineering — that is, the road’s materials and structural composition — and the collected measurement data is essential for developing methods for condition assessment.

In recent years, a new type of sensor has begun to be used, fundamentally producing what are known as georeferenced point clouds. These provide high-resolution information that appears capable of delivering accuracy comparable to traditional measuring equipment. It will be exciting to see how this technology can be applied in the future.

The primary source of information is VTI’s measurement vehicle, the MRP, from which large amounts of data are collected concerning both the road surface and the surrounding road area. Following data collection, the material is usually structured and, where necessary, synchronised with other data sources, such as weather statistics.

Finally, the measurement data are analysed and interpreted to clearly identify the road’s deficiencies and strengths in an effective and meaningful way.
