PRECURSOR SYSTEMS ANALYSES OF AUTOMATED HIGHWAY SYSTEMS. ACTIVITY AREA I -- IMPACT OF AHS ON SURROUNDING NON-AHS ROADWAYS

Deployment of an Automated Highway System (AHS) facility has a significant impact on a facility's capacity and demand. It also impacts the demand of remaining non-AHS lanes of the same facility and the demand of surrounding non-AHS roadways (both parallel and feeder facilities). The impacts of the AHS deployment must be assessed with respect to issues and risks that arise as the AHS is deployed. The potential redesign or reconfiguration of the existing roadway itself could impact its capacity and its demand of the existing roadway. In any transportation corridor, a significant increase in transportation capacity typically reduces demand on parallel roadway facilities, but can significantly increase demand on feeder facilities. Also, when transportation capacity and demand are significantly altered in a specific corridor (such as with the construction of a new highway or fixed-guideway system or the reconstruction of a two-lane facility to a four- or six-lane facility with limited access), impacts also occur with respect to socioeconomic and environmental issues. For example, increased development occurs at entrance and exit points along the corridor and, in particular, along feeder roadways and facilities. At the same time, development and land uses along existing parallel facilities can experience significant reductions in traffic and exposure. Depending on the specific AHS deployment that occurs, air quality and noise will also be impacted along the corridor and feeder roadways and, generally, within the corridor's influence area. A careful assessment of the impacts, issues, and risks of the AHS deployment on surrounding non-AHS roadways will include the use of models. The task will evaluate the traffic, land use, environmental, and socioeconomic impacts of AHS.
