Abstract

A contemporary control option in dynamic traffic management is to dynamically allocate motorway lanes to distinct user-classes. Field studies have shown promising results for specific open-loop lane allocation control strategies (e.g. overtaking prohibition of trucks, dedicated truck- and HOV-lanes, tidal flow control). However, from the viewpoint of optimally using the infrastructural facilities, the applied dynamic lane allocation control schemes are inefficient since neither the dynamics of the heterogeneous multilane traffic flow, nor the changing traffic demand and traffic composition are take into consideration.

Recently the authors' developed a macroscopic multilane multiclass flow model able to simulate heterogeneous traffic operations on large multilane motorways. In this paper we show the effectiveness of a model based control approach to the lane allocation control problem. To this end, the macroscopic flow model is used in an automated control environment.

A comparative analysis between different control strategies, such as static, feedback, and model-based (predictive) control is performed using a microscopic traffic flow simulation tool. The control strategies are compared by determining changes in various performance indicators, reflecting the different objectives (efficiency. safety) of the multiple user-classes and target-groups.
