Automated Highway System (AHS) WBS C1 Final Report: Develop Initial Suite of Concepts & Workshop #2

Task C1 is the first in a series of activities to define and assess alternative concepts for the Automated Highway System (AHS). Specifically, the goal of this task was to develop a set of six high level concept families for more detailed analysis in subsequent tasks. Six major characteristics distinguish AHS approaches at this level, with the most fundamental being the allocation of intelligence, since it drives the allocation of sensing, processing and decision making. The alternatives range from an autonomous vehicle to a system completely controlled by infrastructure electronics. Separation policy has moving slots, or free agents, or platoons of vehicles. Lane sharing between manual and AHS-equipped vehicles, the manner in which they are separated, the mixing of vehicle classes, the approach to entry and exit and the level of automation of obstacle detection and avoidance are also important characteristics. Five teams evaluated these concepts relative to throughput, safety, cost, flexibility and acceptability. In a parallel activity, seven contractors developed independent AHS concepts. The Workshop presented conclusions and candidate concepts to the stockholders. Their feedback resulted in five final concepts: Independent Vehicle, Cooperative Vehicle, Infrastructure Supported, Infrastructure Assisted, and Adaptable.
