• Abstract:
  The California Polytechnic State University (CalPoly) was selected by the Federal Highway Administration (FHWA) as part of the Partners for Advanced Transit and Highways (PATH) team in the Precursor Systems Analyses (PSA) of the Automated Highway System Program (AHS) to investigate the urban and rural AHS comparison. The project goal was a “high level” analysis identifying the differences/similarities of issues and risks associated with rural versus urban AHS. Several potential AHS operating mode alternatives were developed through “representative system configurations” and operating concept variable combinations. Alternatives are mapped in the “Operating Mode Input Matrix” and grouped in four basic stages of development, I1 through I4 (ultimate system). System overall performance (for various modes of operation) was assessed. Discussion on the impacts of differences in the evaluation of urban and rural settings follow. Representative System Configuration variables include guideway separation, heavy vehicle handling and intelligence/authority distribution while operating variables include vehicle spacing, speed and demand levels. Theoretical capacity, safety and environmental impact as it applies to air quality are addressed for the operating modes analyzed. Assessments were made by partitioning of the initial questions in subsets of issues. Every group eventually tries to focus its investigation to the differences and similarities between urban and rural AHS deployments as viewed through the prism of the group-specific issues. The subsets studied are the following: AHS impacts to users. AHS impacts to society. AHS and the Transportation Management Centers (TMCs). AHS and Commercial Vehicle Operations (CVOs). Design Impacts of CVOs. AHS and air quality. AHS and the legal system. Impacts of vehicle braking capability and potential AHS capacities.
