Highlights Overview of modeling approaches incorporating capacity-drop within the simple discretized LWR-type (CTM-like) models. A new modeling approach is proposed that enhances the realistic behavior of the basic discretized LWR model. A theoretical analysis has been performed indicating the relation of the new modeling approach with the continuous LWR model. The presented modeling approaches are tested in calibration and validation using real-data from a motorway network in U.K. Qualitative and quantitative comparisons of the selected modeling approaches are also presented.

    Abstract First-order traffic flow models of the LWR (Lighthill-Whitham-Richards) type are known for their simplicity and computational efficiency and have, for this reason, been widely used for various traffic engineering tasks. However, these first-order models are not able to reproduce significant traffic phenomena of great interest, such as the capacity drop and stop-and-go waves. This paper presents an overview of modeling approaches, which introduce the ability to reflect the capacity-drop phenomenon into discretized LWR-type first-order traffic flow models; and also proposes a new approach. The background and main characteristics of each approach are analyzed with particular emphasis on the practical applicability of such models for traffic simulation, management and control. The presented modeling approaches are tested and validated using real data from a motorway network in the U.K.
