Table 4B – Level of Service and Volume to Capacity RatioClass II RoadwaysLevel of ServicePercent Time-Spent FollowingA < 41B 40-54C 55-69D 70-84E >85FLOS F applies whenever the flow rate(>3200 passenger cars per hour) exceedsthe capacity of the roadwaySource: Highway Capacity Manual, 2000To complete the capacity analysis, input criteria specific for each roadway is needed.These inputs include the roadway geometry, terrain and traffic operations. Trafficoperations data includes the direction of traffic flow, the hourly volume of the roadwayand the peak-hour factor. Each of these specific criteria helps to determine the LOS ofthe roadway. The results of the analysis are presented in Table 4C.Both the existing (2003) and the future year (2030) LOS were determined for eachroadway. In order to calculate the future year traffic, a growth factor of 1.5% per yearwas utilized. This factor was determined in coordination with OKI and is consistent withOKI’s Long Range Transportation Plan.Roadway Capacity Analysis ResultsAs illustrated in Table 4C and Figure 4-2, there are minimal changes in the LOS for eachof the roadways. The complete data sheets for each roadway are included in theappendices of this report.RoadwayTable 4C – Highway Capacity Analysis Results% Time SpentFollowingFacilityClassAverage Travel Speed(MPH)LOS2003 2030 2003 2030 2003 2030Wilson Creek Class II 49.0% 55.5% NA NA B CYork Ridge Class II 40.6% 42.8% NA NA B BCole Lane Class II 39.5% 44.9% NA NA A BN Dearborn Road Class I 35.1% 38.1% 32.8 31.7 E EState Line Road Class I 44.6% 51.3% 29.7 28.0 E EJamison Road Class I 54.6% 59.1% 27.0 26.7 E EWilson Creek Road, York Ridge Road and Cole Lane are currently functioning at anappropriate LOS and should continue to in the future. While immediate capacity addingprojects for the Class II roadways is not warranted at this time, regular and appropriatemaintenance on these roadways should continue.North Dearborn Road, State Line Road and Jamison Road are all exceeding anappropriate LOS at the present time and continue to maintain a LOS E in the horizonyear. One option to correct this problem is to increase the capacity of the roadway byutilizing a four-lane section. Given the existing development and current geometry,widening these roadways could be an expensive proposition and may be disruptive toDearborn County Transportation Assessment Page 4-3
