I I. I I I I I I I I~ I I I I I I I. I I A traffic impact study was completed by Parsons Transportation Group for the AUAR study area in July 2002 to determine the impacts resulting from traffic anticipated to be generated by the planned development scenario. The study included an analysis of existing (2002) traffic conditions, future (2005 and 2020) traffic conditions with and without the proposed development (Build and No-Build), and operational impacts to area roadways. The traffic study included an analysis of roadways within and immediately adjacent to the AUAR study area that are anticipated to be impacted by the proposed Guidant Campus expansion. The traffic impact study forecasted future traffic volumes and examined the operational characteristics of existing and future conditions. The primary measure that is used to analyze these conditions is level of service (LOS). The LOS characteristic is an operational comparison of the ability of a road or intersection to accommodate traffic flow and remain uncongested. The LOS of an intersection is generally presented as an alphabetic rating from A to F, with A indicating minimal delays and F indicating significant delays. Intersections are generally considered to be operating at capacity at LOS D and to exceed capacity at LOS E and F. The following text summarizes the findings of the traffic impact study. Existing Roadway Systcm The Guidant Campus (the AUAR study area) is located northwest of the Lexington A venue/I-694 interchange. Access to the site is currently providcd via CR F, CR 96, lIamline Avenue, Lexington Avenue, and I-694. Following is a brief description of these roadways, including how they provide access to the site and existing average daily traffic (ADT) volumes. . CR F is a two-lane collector roadway that runs east-west and provides access to the Guidant Campus on the south via Fcrnwood Drive and two driveways (known as the west and east driveways). The existing averagc daily traffic (ADT) for CR F is 8,400. . CR 96 is a four-lane minor arterial roadway that runs east-west and bisects Lexington Avenue and lIamline Avenue, north of the study area. The existing ADT for CR 96 is 19,000. . Hamline Avenue is a two-Ianc minor arterial roadway. Visitor access to the Guidant Campus is currently provided via Hamline A venuc. Hamline Avenue becomes Snelling Avcnue south ofI-694. Traffic traveling west on 1-694 can cxit at Hamline A venue and gain access to the site; however, traffic traveling east on l-694 can only travel south on Snelling Avenue thereby not providing access to the Guidant Campus. Hamline Avenue has an cxisting ADT of 12,000. Lexington Avenue, a minor arterial roadway, has two lancs southbound, between 1-694 and CR 96. Northbound Lexington Avenue is two lanes, from 1-694 to Guidant Drive North; however, it is only one lane from Guidant Drivc North to CR 96. There are cLlnently two access points to the Guidant Campus from Lexington Avenue - Guidant Drive North and Guidant Drive South. Lexington Avenue has an existing ADT of17,100.
