The purpose of this study was to compare cycle flows and speeds from two different cycle measurement equipment. The result has also been compared with the processed video data and manual counts. The measuring equipment are Viscando’s equipment OTUS3D and VTI´s TA-89. OTUS3D is a camera with 3D functionality, and it detects tracks and classifies these into different road user categories. TA-89 (where TA stands for Traffic Analyzer) is developed by VTI and is adapted for detecting both bicycles and motor vehicles. We also used a video camera from the OTUS3D system, to enable a manual calculation.

The test site for the study is a pedestrian and bicycle path that crosses a ridge in Vallaskogen in Linköping. The area is located between the district of East Valla and campus. It is a fairly steep slope where the direction towards the campus is uphill and the direction to the East Valla / city center is downhill. Five days that did not include losses of flow were selected for the analyzes. The selected periods were 3 to 4 September (Saturday and Sunday) and 6 to 8 September (Tuesday to Thursday). In addition to this, we chose an hour with high flow and an hour with low flow where video processing was conducted. Furthermore, we used an hour and 50 minutes of manual counting.
