A combined model for dynamic network O-D distributions.

A combined approach for dynamic O-D (origin-destination traffic) in urban networks is proposed. With the initial estimated O-D set, the link-incident matrix can be computed with any acceptable dynamic traffic assignment model and generate a revised distribution of network O-D set. To improve the estimation accuracy and also account for the impact of urban signals, an intersection O-D estimation model is presented that can produce an additional set of system observation constraints based on either existing or estimated intersection turning fractions. The results of simulation experiments indicate that the proposed method is quite promising. For the covering abstract see ITRD E114174.
