Randomness of Capacity--Idea and Application

In this paper, the capacity of a freeway facility is described as a random variable. A methodology for the estimation of capacity distribution functions based on empirical data is introduced. Capacity analysis of freeway sections with long-term construction zones is presented as an example for the application of the methodology. The paper discusses the coherence between conventional constant-value capacities and stochastic capacity distributions. Moreover, the probabilistic concept is included into a model for the analysis of traffic flow quality over a whole year. This technique also provides a quantitative assessment for oversaturated conditions.
