Until now, motorcycle data have not been reported in the traffic measurements carrried out by the National Road Administration, but from now on the Road Administration will also report motorcycle flows and speeds. As there is no definite indication of how the Road Administration's measuring system registers motorcycles, the VTI was commissioned to study different measuring systems for motorcycles and the performance of the systems. The first step was a literature search, which led to a survey of 15 different measuring systems. Descriptions and information were studied, after which performance characteristics and relevance to Swedish conditions were evaluated. This resulted in two measuring systems being chosen for testing and evaluation. These were the National Road Administration's METOR 2000 and the VTI's TA-89. Test measurements were arranged with five motorcycle riders. The results showed that both systems registered motorcycles, but the METOR had difficulties in registering motorcycles at the far end of the sensor tubes. There were problems with both systems in obtaining correct registrations in situations where motorcycles were close to each other or to another vehicle.
