Capacity of shared/short lanes at unsignalized intersections.

This paper presents an analytical theory, based on probability theory, for estimating the capacity of a combination of shared and short lanes at unsignalised intersections. This theory combines the existing procedures for estimating the capacity of shared and short lanes. It was tested by simulations in the style of KNOSIMO simulation, and it can be used for arbitrary lane configurations. For simple shared/short-lane configurations, explicit equations are derived for estimating capacity. For complex shared/short-lane configurations, iteration procedures are given. For practical applications, a graph is presented to facilitate the iterations needed for calculating the capacity of complex shared/short lanes. As a special case, so-called flared minor approaches are treated according to the theory derived. (A)
