Until now motorcycle data have not been reported in the traffic measurements carried out by the National Road Administration, but from now on the Road Administration will also start reporting motorcycle flows and speeds. As there is no definite indication of how the Road Administration's measuring device registers motorcycles, the objective of this study is to analyse different measuring devices for motorcycles and the performance of these devices. The first step was a literature search resulting in a survey of 15 different measurement devices. Descriptions and information were studied, after which performance characteristics and relevance to Swedish conditions were evaluated. This resulted in two measuring devices 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 motorcyclists. The results showed that both devices registered motorcycles, but the METOR had difficulties in registering motorcycles at the far end of the sensor tubes. Both devices had problems in carrying out correct registrations in situations where motorcycles were close to each other or to another vehicle. (A)
