Registration and Analysis of Traffic Conflicts Based on Video

Abstract

For the evaluation of counter-measures or new road design elements the analysis of road user behaviour may be very helpful in understanding the functioning of the traffic process in relation to local characteristics. By means of unobtrusive observation of road user behaviour based on video an objective quantification of behavioural aspects such as speed, speed changes, path chosen, place of stopping, etc is carried out. For describing the danger involved in an interaction between road users the time-to-collision (ttc) is used. After a short description of the method itself some applications are discussed, which illustrate that the method not only enables an objective registration of traffic conflicts, but also gives good possibilities for further analysis of the underlying behaviour of road users.
