Modeling And Simulation Of The Automated Highway System

This report presents the hierarchical structure for the control design of an Automated Highway System (AHS). This control hierarchy has four layers: network, link, coordination, and regulation. It is used to model different AHS proposals. Control layers and the internal structure of each layer and the interfaces between then are described. Three basic maneuvers are described: join, split, and change lane. The SmartPath simulation tools are described to enable simulating AHS scenarios. The advantages of SmartPath include providing a graphical interface, providing microsimulation, and also providing distributed simulation, so that different sections of the highway network can be simulated in different processors.
