This report examines platoon behavior during non-nominal operations, most especially due to emergency braking. Three main topics are discussed: multiple-collision wave propagation effects for homogeneous platoons with and without lead vehicle information, intra-platoon collision behavior of...

The purpose of this report is to investigate the effect of selected parameter variations on the response of a platoon. The response of a platoon under different control algorithms is also examined. A four-car platoon with prescribed lead car dynamics was used for simulations and vehicles in the...

The goal of this project is to develop a user-friendly simulation program which will allow the study of platoon dynamics in both nominal and emergency scenarios. The report discusses the issues investigated during the second phase of the project, including the inclusion of a vehicle model with...

This report studies performance issues in Automated Vehicle Control Systems (AVCS). Specifically, it addresses the automatic braking controller design issues, effects of braking on Intelligent Vehicle Highway Systems (IVHS) lane capacity, performance of platoons with various information...

This paper describes a fault tree analysis of an automated freeway. The design is characterized by extreme emphasis on vehicle-borne intelligence, and by the presence of a multiplicity of automated lanes. The system is platooned. At the end of the paper there is a brief discussion of the...

This report discusses the issues investigated during the first phase of a project which focuses on the development of a simulation program which will allow the study of platoon dynamics in both nominal and emergency scenarios. Preliminary issues include collision detection between the vehicles...

The focus of this work is to derive a technique of safety analysis for an automated freeway system. To demonstrate the method of safety analysis a procedure called fault tree analysis is applied. The specified freeway operates with vehicles in platoons. The safety criterion used here is that two...

This paper investigates the feasibility of a fuzzy logic control (FLC) algorithm for lateral control in a lane change maneuver in an automated highway system (AHS). The lane change maneuver takes the vehicle from lane following control in one lane to lane following control in an adjacent lane. A...

This document presents Dynamic Visualization, a project associated with the California PATH Program. The objective of the project is to develop a software which can animate automated highways, visualize the dynamics of automatic vehicles, and help the design and evaluation of automatic vehicle...

A Fuzzy logic controller (FLC) is designed and implemented in real time on a Toyota Celica test vehicle to achieve control of the lateral motion of the vehicle. The structure of the FLC is modularized as a feedback, preview, and gain scheduling rule base. The parameters of the FLC are tuned...
