Title Traffic Analysis of the KY 8 Corridor in Bellevue and Dayton Kentucky
Abstract This report provides an inventory of the existing and potential traffic conditions along KY 8 (Fairfield Avenue) in the cities of Bellevue and Dayton in Campbell County Kentucky. The inventory provides a baseline condition and forecasted future condition to aid in evaluating transportation improvements throughout the corridor. The study corridor on KY 8 extends for 1.3 miles from Riviera Drive in Bellevue through Berry Street in Dayton.

Introduction
This report provides an inventory of the existing and potential traffic conditions along Kentucky State Route 8 (KY 8/Fairfield Avenue) in the cities Bellevue and Dayton, Kentucky. This report also documents the travel demand modeling and traffic simulation that was conducted by OKI to support this study. The inventory and simulation provide a baseline condition to aid in evaluating future transportation improvements throughout the corridor. The study corridor on KY 8 extends for 1.3 miles from Riviera Drive in Bellevue to Clay Avenue in Dayton. Information for this report comes from field observations of travel times and traffic conditions within the corridor, OKI’s Geographic Information System and OKI’s travel demand and simulation models. An overview map, an aerial photo and photographs of selected locations are provided in Figures 1, 2 and 3. Section 2 provides a demographic overview of current and forecasted 2030 population, household, and employment information. Section 3 summarizes the existing travel performance of the corridor based on observations of travel time and speed. Section 4 describes the process to develop the traffic simulation and presents the simulation results with projected changes in travel performance assuming the expected changes in local demographics and regional travel. Also included in this section are results of one alternative intersection improvement and screen shots of simulation images. Section 5 provides some conclusions of this traffic analysis.
