Traffic Impact Study 1 New Brighton Exchange Update 1. Introduction a. Purpose of Study Spack Consulting prepared a Traffic Impact Study for the New Brighton Exchange in 2014 (known as the 2014 TIS from here on). That study included analysis for a large amount of development along the Old Highway 8 corridor in New Brighton, Minnesota. Since that study was completed, a significant portion of the proposed development has been constructed. This study revisits the 2014 TIS to determine if the recommendation from that study of a traffic signal at Old Highway 8/14th Street is still valid or if different traffic control is needed as well as if the configuration of Old Highway 8 could be modified. For those not familiar with the general concepts and terms associated with traffic engineering, The Language of Traffic Engineering guide is included in the Appendix. b. Study Objectives The objectives of this study are: i. Document how the study intersections and roadways currently operate. ii. Forecast the amount of traffic expected to be generated by the remainder of the proposed development. iii. Determine how the study intersections and roadways will operate in the future with and without the proposed development. iv. Recommend appropriate mitigation measures if poor operations are identified, comparing those recommendations to the 2014 TIS recommendations. v. Evaluate the feasibility of converting Old Highway 8 to a three -lane facility (one lane in each direction with a center, two-way left turn lane). For the purposes of this traffic study, the study intersections analyzed match those from the 2014 TIS and are: i. Old Highway 8 & Highway 96 ii. Old Highway 8 & 14th Street iii. Old Highway 8 & Central Park Boulevard iv. Old Highway 8 & Northwest Parkway v. Old Highway 8 & 10th Street The main roadway corridor studied in this document is Old Highway 8 between 10 th Street and Highway 96. It should be noted traffic expected from the proposed development will have minor impacts on other corridors and intersections beyond those studied here. Furthermore, this study does not account for the existing roadway conditions such as pavement quality or appropriate drainage.
