Objective data. Parameters recorded by instrumented vehicles are detailed in WP4 deliverable. The recorded parameters in all four studies are: • PTW position • Speed • Acceleration/Deceleration • Brake activation (and brake pressure in some sites) • Steering angle • Throttle position • Activation of turn signal • 2 channels of video (the first one filming the face of the rider and the other the raod in front of the scooter) The observation of the aforementioned parameters can, following the appropriate analysis, demonstrate different riding patterns. In addition, riding patterns could be classified and if “extreme” riding behaviour/patterns are found, i.e. patterns that do not resemble those that yield “normal” behaviour, it can be assumed that a conflict has taken place. However, the aforementioned analysis could not easily extract such information. Hence, in addition to the riding parameters, video footage will also be used. Hence, there will be front view video and xxxxx’s face video. From this, relevant parameters can be extracted: elements of the road scene such as longitudinal distance and relative speed with preceding vehicles; other elements of the preceding vehicle behaviour; obstacle appearance; and gaze direction. These parameters will allow a better understanding of the rider’s behaviour by reconstructing the riding scene. Hence, although significant quantitative parameters will not be recorded directly, for example longitudinal and lateral headways, the addition of video footage might help overcome this limitation and manage to identify riding patterns and critical situations.
