What is A new approach to traffic behaviour: I. Modelling of “following-defence” behaviour about?

A new type of car-following model is proposed on the basis of Proxemics (anthropological theory of man's use of space) and the catastrophe theory. It is assumed that the proxemic character of a car is similar to that of man: a car has a series of distance zones around it, with which its driving behaviour and senses are associated. Under this assumption, driving behaviour of a car in relation to the leading car is classified into four modes; "defence", "following", "pursuit" and "free running". Through qualitative study of the discontinuous phenomena between these modes, the sensory shift between "following" and "defence" is explained by the cusp catastrophe. In order to express the driver's psychological state, z-sense (sense of security) is introduced. Then, a goal of driving is defined and the growth of acceleration/deceleration desire is explained by unbalance between the goal and the current psychological state. As a result, a "foUowing-defence" behaviour model is constructed by connecting the dynamical equations of the psychological state and the physical state.
