PRECURSOR SYSTEMS ANALYSES OF AUTOMATED HIGHWAY SYSTEMS. ACTIVITY AREA J: AHS ENTRY/EXIT IMPLEMENTATION

The Automated Highway System (AHS) entry and exit systems must be consistent with the AHS goals of safety, throughput, user comfort, and environmental impact. The systems must be designed to enable the vehicles and operators to safely enter and exit the roadway at rates that ensure that the AHS's throughput objectives are met. The entry and exit areas must enable processing and deployment of the vehicles with minimal discomfort to the operator. The requirements for entry and exit system designs are influenced by the AHS concept. For example, a platooning concept may involve forming entire platoons in entry lanes prior to insertion into the roadway, while for the uniform headway spacing concept, vehicles may be released individually into the roadway. The infrastructure requirements also may differ substantially among AHS concepts. For example, longer and more entry lanes may be required to form platoons before entry to the roadway. With multivehicle pallets, the entry and exit lanes probably would have a much different design than concepts involving individual vehicles. This task includes identifying measures of effectiveness (MOEs) for evaluating entry/exit strategies and land-use requirements for each RSC and will be closely tied to the AHS roadway deployment analysis (activity area H), automated check-in analysis (activity area B), and automated check-out analysis (activity area C). Thus, this work has a high priority similar to that of areas B, C, and H. We recommend that the performance of these activity areas be well coordinated.
