Casey's Headquarters

Ankeny, Iowa

Bishop Engineering Company, Inc. initiated this traffic study to identify potential traffic impacts on the adjacent roadway network and provide traffic mitigation measures, if necessary, due to a proposed Casey’s Corporate Headquarters office development. The proposed development would be located immediately adjacent to the existing Casey’s Corporate Headquarters and would be a two story 74,540 square foot Casey’s Corporate Headquarters office building. The site had two existing access points on SE Convenience Boulevard. 

Vehicular operational analysis for this study was performed using the methodology of the 6th Edition Highway Capacity Manual (HCM) through PTV Vistro 5.00-00 traffic analysis software. Operational analysis is generally categorized in terms of Level of Service (LOS). LOS describes the quality of traffic operations and is graded from A to F; with LOS A representing free-flow conditions and LOS F representing congested conditions.

LOS D or better is generally identified as acceptable in urban conditions. The analysis presented  indicated the study intersections would all operate at acceptable LOS C or better during the AM and PM peak hour conditions through 2038 with buildout of the proposed Casey’s Corporate Headquarters office development. As such, no mitigation measures associated with the proposed Casey’s Corporate Headquarters office development were recommended.
