Lane assignment on automated highway systems
The automation of highways as part of the IVHS program is seen as a way to alleviate congestion on urban highways. This thesis discusses the concept of lane assignment in the context of automated highway systems (AHS). Lane assignments represent the scheduling of the path taken by vehicles once …

Modeling Automated Highway System Guideway Operations
… operational characteristics of a Maglev-based Automated Highway System and how it would interact with freeway operations. The extension of traditional traffic flow phenomenon, including weaving, merging, and stopping distance, into the automated system is looked at. These are also extended into …

Vehicle merging control for an automated highway system
This research presents theoretically an automated vehicle merging control which is an important subsystem of AHS. The goal of the system is to automatically control the vehicle merging from ramp to the AHS lane in an efficient, smooth and safe manner. The entire merging process is divided the a …

Micro-macroscopic modeling and simulation of an Automated Highway System
… may ultimately yield the largest benefits is the Automated Highway Systems (AHS). The AHS approach to enhance the performance of our highways is to apply automation techniques to vehicles and roadways to increase the capacity and efficiency of existing facilities, while retaining the advantages of …

Platoon modal operations under vehicle autonomous adaptive cruise control model
… 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 platoon operations. Desired …
