Abstract

This paper presents a dynamic network loading (DNL) model that can be used both for Dynamic Traffic Assignment (DTA) and for an accurate description of traffic. The proposed DNL model is composed of: (1) the link model based on the LWR macroscopic first order model solved with the Wave Tracking method, (2) a new intersection model that generalizes the Daganzo macroscopic merge model to complex intersections, and (3) a traffic signal modelthat represents the mean effects of stage alternation on traffic in termsof delays and of capacity restrictions. The model can be consistently solved with various precisions scales: low precision scales to quickly provide a good estimation of travel times on the network for DTA purposes, and high precision scales for accurate descriptions of traffic with all the desired modeling details.
