Traffic Data – Projected traffic data in the study area such as average daily traffic, the K- factor, directional splits, and percent trucks shall be provided by the State from Transportation Planning and Programming (TP&P). From this information, the Engineer shall derive the Design Hourly Volumes (DHV’s) and AM and PM peak hour traffic volumes for use in the Year 2037 no-build and build condition design model year. The signalized intersection turning movement counts shall be projected forward based on the same defined growth rate from the TP&P information. The Engineer shall summarize the projected traffic volumes on the schematic sheets and include the line diagrams provided by TP&P. Data collection shall also include travel time calibration data per FHWA standards and intersection turning movements at the interchanges and adjacent intersections within the area of influence. Utilizing FHWA’s eight step guidance and the 2010 Interstate System Access Informational Guide, the Engineer shall provide docu...
