In order to provide reliable control algorithms on PATH automated highway system, knowledge of the transient aerodynamic forces is important from the point of the controlla- bility of the platoon and individual vehicles. In a passing maneuver, the platoon members may experience severe...

This report describes possible objectives for a Field Operational Test (FOT), to be conducted following the completion of the National Automated Highway System Consortium (NAHSC) mission in 2002. At that time, it is anticipated that there will be one or more FOTs in which ordinary drivers will...

In this report, the authors present a modified safe join trajectory for the regulation layer maneuvers of the hierarchical PATH Automated Highway System (AHS) architecture. This new design presents a more conservative behavior for the controlled platoon in a maneuver. The new trajectory reduces...

The vehicles in a platoon will experience transient aerodynamic forces as vehicles leave and join the platoon at various locations. A platoon of scale vehicle models is placed in a wind tunnel and measurements are made of the transient forces and moments as one of the vehicles is moved into and...

This report focuses on dynamic modeling and lateral control of commercial heavy-duty vehicles for highway automation. Two types of dynamic models are developed in the study of lateral control of tractor-semitrailer vehicles in an Automated Highway System (AHS): a complex simulation model and two...

The purpose of this study was to demonstrate the travel and emissions impacts of urban freeway automation scenarios and to compare these to travel demand reduction scenarios, such as travel pricing and land use intensification. The Sacramento regional travel demand model set was used and an...
