MODELLING LANE DISCIPLINE ON MULTILANE UNINTERRUPTED TRAFFIC FLOW

This paper details a model to simulate 'untidy' traffic flows, typical of those in developing countries, where conventional lane discipline is not followed. Its first part discusses previous work on the longitudinal and lateral characteristics of traffic flow, using car following models. The concept of traffic 'untidiness' is defined and given a simple statistical representation, and its consequences are outlined. Two sets of empirical traffic observations were collected from some European (British, German, and Belgian) and Turkish highways; they represented the situations of developed and developing countries, respectively. Comparisons of some of the results between the two sets revealed the different characteristics of tidy and untidy traffic flows. The paper gives details of a simulation model of untidy traffic, which includes: (1) consideration of lateral discomfort experienced by some drivers; (2) leadership analysis; (3) a new car following analogy and mathematical model for untidy traffic; (4) lane changing in untidy traffic; and (5) the simulation mechanism. One of the most important parts of the research was to simplify the concept of untidiness. A new car following model was established, which is suitable for some cases where conventional car following models cannot be applied. Some of the empirical findings have useful practical implications.
