For those responsible for maintaining roads, grip as well as longitudinal and lateral profile are the most important parameters for a reliable road infrastructure. Also route planning, such as curve radius and the longitudinal and lateral inclination are of great interest, as these parameters in combination with the road condition data give a vital indication of the traffic safety of a route section.
The data material supplied by RoadSTAR is unique throughout Europe with regard to quality, resolution and area coverage. This data pool enables the Mobility Department to carry out exhaustive observations as to the connection between road infrastructure and accidents. Thus the analysis of the causes of an accident don't have to take individual places of accident or places of accident accumulation as a starting point, but can cover the whole network. Subsequently models for the prediction of accidents are developed from these data. Road-related data are also relevant for all traffic telematic applications.
By the development of RoadSTAR more accurate findings of the road surface conditions can be obtained, thus making a material contribution to traffic safety.
The combination of all these parameters enables a timely and economic initiation of the necessary redevelopment measures. The examination of connected data and the comparison with similar points in the residual road network results in the possibility to derive measures for an economic mitigation of existing and (as a preventive measure) potential accident black spots.
