Abstract
The main purpose of the present study is to identify what distinguishes normal and critical encounters, and how this is related to road user decision- making. To reach this goal, the present analysis of road user behaviour is focussed on the use of time- based measures since these combine several dynamic aspects in encounters with other road users or with the road environment. A video- based observation- and analysis- method was developed that enables an objective quantification of dynamic characteristics of road user behaviour in various traffic situations.
