ABSTRACT
The present volume focuses on several aspects related to the perception of PTWs by other road users. In order to provide a summarised overview about the main findings from the case studies, it is useful to restructure the outcomes according to the basic behavioural taxonomy introduced earlier, and with respect to the classification of typical errors (see Chapter 3) conducted by other road users in the interacting course with PTW riders. Based on the three key behaviours emphasized by Crundall et al. (2008), two main error categories were differentiated in Chapter 3: detection errors, referring to road users’ failure to look at and to properly detect a PTW, and decision errors, referring to the inadequate appraisal of an oncoming PTW in terms of its speed and/or its path. The results can be further discussed on a second level with respect to the impact of PTWs’ visual characteristics as bottom-up component within the perception processes, and on the other hand, with respect to the characteristics of the observer and decision-maker operationalizing the top-down influences, and, respectively, the cognitive factors for the road user interacting with the PTW in traffic.
