No easy task for advanced driver assistance systems to read road markings correctly

It is not always easy for advanced driver assistance systems to read road markings. Sunshine, shadows and rain are just some of the factors that can affect readability. The systems are also occasionally confused by longitudinal cracks. VTI researcher Sara Nygårdhs is project manager for...

VTI train simulator on tour

The VTI train simulator was included in a research study during which train drivers were able to try out new designs of the European Rail Traffic Management System (ERTMS) signalling system. The aim is to create optimal signalling projects combined with the best possible work environment for the...

Expanding road capacity in urban areas resulted in urban sprawl, more traffic and more motorists

By studying the effects of expanding road capacity in two urban areas in Norway; Ålesund (the Blindheim Tunnel) and Oslo (South Corridor), researchers found that the road capacity expansion resulted in urban sprawl, longer work trips and more traffic. The rush-hour congestion was not...
