In this paper, the authors study the capacity of key Automated Highway Systems (AHS) operating scenarios. The effect of the lane-flow rule, platooning or free-agent, as well as the lane barriers, on AHS capacity are studied. Special attention is paid to the interaction between the lane-flow rule...

This is the final report of the PATH research project "Bottleneck Evaluation Model." The goal of the project was to develop a computer tool for evaluating capacity and travel time benefits of PATH improvements. The Bottleneck Traffic Simulator (BTS) is used to investigate the time benefits of...

We investigate the effect of a number of design alternatives on the safety and capacity of an Automated Highway System. Our methodology makes use of two computational tools, designed to highlight the fundamental limitations of the vehicle dynamics, sensing and control strategies and...

This dissertation investigates various platooning strategies and their impact on the performance of the platoon. Various decentralized control algorithms are designed and their performance is characterized in terms of the minimum attenuation of the maximum spacing errors that can be guaranteed...

This report presents the theoretical development of a method to evaluate differing platoon control strategies and determine each strategy's worst case behavior under bounded parametric variations. The approach is useful in aiding a platoon designer in determining the robustness a design strategy...

This paper shows how the evolution of multicommodity traffic flows over complex networks can be predicted over time, based on a simple macroscopic computer representation of traffic flow that is consistent with the kinematic wave theory under all traffic conditions. After a brief review of the...

In this report, the estimation of longitudinal states in a four-wheel platoon is derived, discussed and illustrated numerically. The general procedure in the process is the use of dynamic equations and data, for finding the estimates and root means squared errors in the estimated of the states...

This report describes the development of a new model that can monitor system performance and derive management and control strategies in real time. It presents the TMERT (Turning Movement Estimation in Real Time) model, a method of estimating turning movement flows from link detected flows at...

A lane change maneuver is one of the many appropriate responses to an emergency situation. The design of an Emergency Lane Change (ELC) maneu- ver for a platoon of two vehicles is considered in this paper. In response to the presence of a stationary or a slowly moving obstacle in the lane or any...
