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 chance of having a collision when the platoon ahead applies and holds maximum braking.

This report describes the implementation of the regulation layer maneuvers for the hierarchical architecture in SmartPath. The report contains information regarding the simulation of automated vehicle control laws in the SmartPath environment. It also provides an overview of the set of maneuvers currently implemented.
