Many ideas have been proposed to reduce traffic congestion problems. One of the proposed ideas is driving in platoon. Constant spacing policy is the most important control policy. It increases traffic density, but it needs very reliable communication channel. Driving with a constant time headway between vehicle is also well known policy and robust control law, but the inter-vehicle distances ar...

Platoon based traffic flow models form the underlying theoretical framework in traffic simulation tools. They are essentially important in facilitating efficient performance calculation and evaluation in urban traffic networks. For this purpose, a new platoon-based macroscopic model called the LWR-IM has been developed in [1]. Preliminary analytical validation conducted previously has proven th...

1 I n t r o d u c t i o n Automated highway systems (AHS) offer the potential of significant improvements in traffic flow volume and stability, as well as safety, when compared with current manually-controlled highway driving (Shladover, 1991). Implementation of AHS requires completely automated lateral and longitudinal control of vehicle motions as well as coordination of the maneuvers of diff...

Vehicle platoon approaches found in literature deal generally with column formations adapted to urban or highway transportation systems. This paper presents an approach in which each platoon vehicle follows a virtual vehicle, in order to cope with issues such as different platoon geometries. Those different types of formations can be encountered in a wide range of field such as the military or ...

Automated vehicle platooning bears high potential to increase traffic efficiency, improve road safety, and reduce fuel consumption. To realize platoons with small inter-vehicle distances, collision safety is the most crucial concern needs be considered carefully. Moreover, it desired attenuate disturbances along platoon which known as string stability. While model predictive control concepts ac...

In this study, field investigation is made by means of videotapes which record traffic flows at several locations on two links in Changchun City, China. After processing the data, traffic flows at each location and vehicle speed distributions on different links are obtained for the platoon dispersion process. The platoon dispersion patterns from the observations are compared with those provided...

The position of a new platoon asset, the Robotics NCO (RNCO), is introduced in the Objective Force Operational and Organizational (O&O) Plan (Unit of Action Maneuver Battle Lab, 2003). The RNCO is expected to assist the Platoon Leader in employing unmanned systems, to be a subject matter expert in platoon robotics systems, and to coordinate unmanned assets in support of reconnaissance and surve...

Achieving speed, safety and energy optimization in vehicle platoons is among the important topics of recent years. In this context, work focuses on improving string stability (SS) heterogeneous platoons. Better SS allows for smaller gap between vehicles, which means shorter time headway Cooperative Adaptive Cruise Control (CACC) or inter-vehicle following-distance platooning. Shorter distance r...

Introduction The public highway systems are used to transport a constantly increasing number of goods and people. In spite of that high increase in traffic, the number of fatal accidents is falling yearly, because of the ever increasing use of technology to develop safer vehicles. Meanwhile, the environmental impact of each vehicle decreases proportionally in that technology partly compensates ...
