Conference paper


The theoretical models of traffic flow, e.g. the time gap acceptance model, are too much simplified in many aspects. In this paper, the gap acceptance model is analysed as a stochastic process. As a result of mathematical analysis, an expression of the cumulative probability of accepting time gaps has been calculated. Furthermore, the effect of pedestrians on left-turn capacity is discussed.
