Vehicle platoon is one of important techniques both for improving the traffic safety and for increasing the traffic network capacity. Vehicle platoon system allows vehicles to drive at the same velocity and to accelerate or brake simultaneously. In this study, we will present the velocity control algorithm of the vehicles in the vehicle platoon and then, apply it to the velocity control of the ...

The type of vehicles in realistic traffic systems are not homogeneous. Impacts the preceding vehicle’s on car-following behavior, fuel consumption and exhaust emissions still unclear. This paper presents a study impacts two types vehicles, heavy new energy flow characteristics, emissions. Firstly, an extended model was proposed by incorporating influence type. Secondly, platoon stability were a...

For the cooperative adaptive cruise control (CACC) vehicular platoon, apart from decentralized controllers, dynamics of a platoon can be affected substantially by information flow among connected and automated vehicles (CAVs). Existing research studies mainly focus on stability analysis platoons where CAVs only adopt predecessor-following (PF) communication scheme; however, when “look” further ...

Cooperative Adaptive Cruise Control (CACC) employs wireless intervehicle communication to allow for automatic vehicle following at small intervehicle distances while guaranteeing string stability. Inherent to the CACC concept, however, is its vulnerability to communication impairments, among which latency of the wireless link, which compromise string stability and, hence, safety. To investigate...

Platoon Collision Dynamics and Emergency Maneuvering I: Reduced Order Modeling of a Platoon for Dynamical Analysis Benson H. Tongue, Yean-Tzong Yang, and Matthew T. White

The objectives of this effort are to develop: (1) control synthesis methods for control algorithms that can be distributed among a platoon of UUVs with minimal inter-vehicle communication requirements, (2) centralized control algorithms that are easily synthesized, generate multi-objective behaviors for a platoon of vehicles, and may potentially be distributed among a platoon of UUVs, (3) decen...

The emergence of Connected and Automated Vehicles (CAVs) promises better traffic mobility for future transportation systems. Existing research mostly focused on fully-autonomous scenarios, while the potential CAV control at a mixed intersection where human-driven vehicles (HDVs) also exist has been less explored. This paper proposes notion “1+n” platoon, consisting one leading n following HDVs,...
