Platoon modal operations under vehicle autonomous adaptive cruise control model
… of adaptive cruise control models and platoon operation logic for Automated Highway Systems in the Advanced Vehicle Control Systems (AVeS). Three control modes, constant speed, emergency and vehicle-following, are defined based on the minimum safe stopping distance, and applied to the …

String Stable Constant-Spacing Platoon with Robustness to Communication Delays and Cutoff
… achieve string stability in constant-spacing platoons. However, the benefits of introducing centralized control are questionable under communication limitations, like delays and cutoffs, which are common in modern traffic networks. Therefore, this thesis develops a new constant-spacing control …

Development of a three dimensional terrain display for a light infantry platoon combat model
… a need for an easily available light infantry platoon combat model that presents a realistic view of the battlefield environment. To meet this need, the author examines the feasibility of developing a realistic three dimensional display of a terrain representation on a personal computer. The …

Environmental Tracking and Formation Control for an Autonomous Underwater Vehicle Platoon with Limited Communication
A platoon of autonomous underwater vehicles provides a compelling platform for studying many challenging issues in multi-agent cooperative control. These challenges include developing cooperative algorithms suitable to practical multi-vehicle applications. They also include addressing intervehicle …

Behavioural adaption of drivers of unequipped vehicles to short time headways observed in a vehicle platoon
… interact with unequipped vehicle drivers (UVDs). Platoons of vehicles comprise a vision for future traffic and are designed to maintain small headways in order to have a beneficial effect on both energy consumption and traffic flow. The overarching aim of this work was to investigate whether the …

From Self To Other In Oliver Stone's Vietnam Trilogy: Platoon, Born On The Fourth Of July, and Heaven And Earth
… 1950s. Among his filmography, we can categorize Platoon (1986), Born on the Fourth of July (1989), and Heaven and Earth (1993)-Stone's so called Vietnam Trilogy-as the most direct depictions of the war and its aftermath, whereas The Doors (1991), JFK (1991), and Nixon (1995) examine the broader …

Design of and Decentralized Path Planning for Platoons of Miniature Autonomous Underwater Vehicles
… schemes for land-based or air-based groups, or platoons, of autonomous vehicles cannot be implemented in underwater applications because of their dependence upon high-bandwidth communication. In current strategies for controlling groups of autonomous underwater vehicles (AUVs), platoon size …

Accounting for midblock pedestrian activity in the HCM 2010 urban street segment analysis
… network. The methodology involves applying a platoon dispersion model to: a) predict the vehicle arrival flow profiles at a downstream signalized intersection; b) use the predicted arrivals to compute the proportion of vehicle arrivals on green; and c) subsequently estimate the delay, travel …

Development of Arrival-Type-Based Uniform Delay Models for Signalized Intersections
The resulting models: (1) Consider platoon duration, flow rate and/or number of vehicles in platoon, (2) Are sensitive to traffic volume inside platoon, and (3) because a distinct delay model was deduced for each arrival type, the need for applying delay adjustment factors was eliminated. …

Design of a cooperative overtaking algorithm for platoons on freeways
Platooning can improve road safety, optimize traffic flow, and raise the driver’s comfort. However, when a platoon is stuck behind a slower vehicle, the total travel time is significantly increased. Overtaking as a whole platoon is a complicated maneuver and there is no communication-based …

Stability and String Stability Analysis of Formation Control Architectures for Platooning.
… stability of formation control architectures for platooning. We consider three important interconnection topologies for vehicles travelling in a straight line as a string: leader following, cyclic and bidirectional. For the leader following topology we discuss modifications that allow reduced …

Modeling Traffic Dispersion
… part, the dissertation focuses on the Robertson platoon dispersion model which is the most widely used platoon dispersion model. The dissertation demonstrates the importance of the Yu and Van Aerde calibration procedure for the commonly accepted Robertson platoon dispersion model, which is …

External communication displays for connected truck platoons in mixed traffic : a federated simulator study
Truck platooning is anticipated to be the first widespread deployment of connected or automated vehicles (CAV). In addition to familiarizing the public with the function of CAV, a truck platoon has proven benefits to fuel consumption by minimizing drag. These are the primary motivations that have …

SAFE REINFORCEMENT LEARNING-BASED GREEN LIGHT OPTIMAL SPEED ADVISORY FOR MIXED-TRAFFIC PLATOONS
This thesis develops a platoon-centric, safe RL-based Green Light Optimal Speed Advisory (GLOSA) system to optimize the CAV speed profile of a mixed-traffic platoon. First, we design a multi-agent RL algorithm to achieve a balance between the energy and travel efficiency of a mixed-traffic platoon, …

Time Headway and Platooning Characteristics of Vehicles on Interstate Highways
Mean time headway for platooning vehicles decreased as traffic volume increased. About 18% to 31% of platooning vehicles had a space gap that corresponds to a reaction time of 0.5 second or less, with more than half of these in large platoon of 5 vehicles or more. About 15% to 85% of platooning …

Developing a Fuzzy Expert System to Examine Hazard Analysis in The United States Army
… ANOVA test in SPSSS. The cluster results showed Platoon and Major as the two most significant predictors for cluster formation on the Foot March Scenario. Of the two only Platoon demonstrated statistical significance on the ANOVA. Prior Service and Platoon were the two most significant predictors …
