Abstract:Deployment of an AHS will require a comprehensive analysis of the facilities contemplated for installation or modification to determine the most appropriate means of implementation. Two basic operational environments, rural and urban, have certain distinguishing features which will affect their implementation strategy. In some cases, urban environments will interface with rural environments, such as a linkage between cities at the city fringe. The significance of these differences is exemplified by considering the rural environment as an intercity linkage. This deployment may involve land acquisition in a rural environment. The land use requirements, cost of land, social and transportation system disruptions of the deployment and implementation processes are expected to be radically different than those considered in an urban area. Perhaps it will be found that there are only certain circumstances in which urban AHS deployment can be reasonably considered as a result of cost or other impacts, requiring the AHS to be feasible only if it can be confined within existing right-of-way. If that is found to be the case, the next step would be to then evaluate the impacts of an AHS confined within an existing right-of-way, and identification of other conditions (cost, environment, noise, schedule, traffic impact, constructability) which may affect deployment. This task will evaluate the application of AHS design concepts to generic and real-world situations that would result in an operational system with minimum negative deployment impacts. Physical conditions such as lanes, how these travel ways interact with adjacent freeway lanes, and how do such travel ways provide access to other travel ways at junctions will be considered. Conceptual level illustrations of what the AHS looks like as it interfaces with other transportation modes and facilities will be required. This document type is resource materials.
