Uptown Transportation Study - OKI

Planning Study ReportPart B: Interstate 71 Access Improvement Study, PID 776284.9. 2005 Level of Service (LOS)As described above, the raw traffic volume count information was used to balance thesegment and ramp daily totals in the north and south bound directions. These balancedtotals were crosschecked with the respective project counts, historic count information, andARTIMIS ATR volume averages by the respective station location.Levels of service were determined for freeway segments, interchange ramp merge anddiverge points, and signalized intersections within the study area using HCS, versionHCS2000TM, Version 4.1d. While new versions of this software have become available foruse during the course of the study, this version has been used throughout to maintainconsistency in the methodology so comparisons of conceptual access improvements can bemade on an equitable basis. See Appendices D and E.4.9.1. Basic Freeway SegmentsThe following tables present the results of the 2005 existing condition analyses performedon the mainline segments of I-71. The interstate is generally operating at a satisfactory levelof service overall. Southbound I-71 from Dana Avenue to the WH Taft Road exit is nearingits capacity in the AM Peak Hour. See Figures 18 to 20 of Appendix C for maps illustratingthe 2005 LOS for I-71. Segments with unacceptable LOS are shown in grey in the table.Table 9: 2005 LOS Northbound Basic Freeway Segments42
