A General Simulation Framework for Modeling andAnalysis of Heavy-Duty Vehicle Platooning
(English)Manuscript (preprint) (Other academic)
Platooning heavy-duty vehicles (HDVs) on highway is a method of improving energy and transport efficiency. On the one hand, HDV platoon driving in small inter-vehicle distances could increase highway capacity; on the other hand, HDVs traveling in small inter-vehicle distances experience significant air -drag reduction and therefore, improve fuel efficiency. However, the majority of research has been conducted on the development of platoon system, very few studies have focused on quantification of the impacts of HDV platooning on traffic flow. This paper initializes a simulation framework to facilitate the study of HDVplatooning and establishes corresponding concept and operations.The longitudinal driving behaviors of HDV platoons is modeled in detail considering the acceleration capability of HDV. The proposed framework is applied in three experimental cases, the first case is to study the impacts of HDV platoons on traffic flow, and the second and third cases are about the influence of traffic on HDV platoon formation. In the first case, simulation outcomes show that increasing percentage of HDV platooning in traffic flow generally results in more dramatic improvements in traffic efficiency while preserving traffic safety for passenger vehicles; in the second and third cases, for the HDV platoon formation, deceleration of the first HDV in low speed during platoon formation will increase the formation time to a large extent in medium and heavy traffic.
