Generally, a two-lane roadway can accommodate 10,000 to 15,000 vehicles per day depending <br />on the distribution of the trips in the peak hour and the amount of access along the corridor. If <br />volumes exceed these thresholds, users begin to experience more delay, vehicle back ups and <br />extended waits to access the corridor. These use problems can lead to an increase in crashes due <br />to the stop and go nature of the traffic and people taking greater risks because they are too <br />impatient to wait for a adequate gap in the traffic stream. <br />Traffic Operations <br />This section of the report identifies future traffic operations at key intersections along County <br />Road 116 during the peak morning and afternoon hours. The traffic operations analysis takes into <br />consideration the need to widen the corridor and implement an access management plan. <br />Data from the existing conditions section indicated that most of the existing intersections <br />currently function at an acceptable level. In the future, with the anticipated increases in traffic <br />volumes, all of the intersections would have operational problems. Table 10 shows the results <br />for future intersection operations assuming the increase in traffic with the existing roadway <br />geometrics. This is considered a "no build" scenario. <br />Table 10 <br />Future Intersections Levels of Service (Year 2025) — No build <br />Intersection — County Road 116 and <br />Level of Service <br />A.M. Peak P.M.

This means that there would be significant delay to <br />motorists traveling in the peak period. Intersections will have long queues and will reduce the <br />ability of the roadway to move traffic. <br />Another analysis on the intersections was run to determine how they would function if County <br />Road 116 was widened to four lanes and the intersections were signalized. The results of this <br />analysis indicate that the roadway would function at a much higher level and that the amount of <br />delay would be significantly lower than it would if the additional lanes were not constructed and <br />the intersections were not signalized. This analysis is referred to as the "build" scenario. <br />Table 11 shows the results for the "build" scenario. <br />SRF Consulting Group, Inc. - 34 - February 2004 <br />
