Floyd County, IndianaFloyd County Thoroughfare PlanSection 4–Alternatives EvaluationOperations modeling indicates that with the forecasted AM and PM peak-hourvolumes the intersection configuration shown in Figure 4.01-5 would operate atLOS C during the AM peak hour and LOS D during the PM peak hour. In the PMpeak hour all left-turn movements and the northbound through movement operate atLOS E. Significant queues can be expected southbound in the AM peak hour andnorthbound in the PM peak-hour on US 150 because of the high forecasted trafficvolumes.Traffic volumes suggest it would only be feasible to have pedestrians cross to themedian of US 150 during the minor road phases, so a sufficient refuge space shouldbe provided for pedestrians in the median of US 150.A recently approved development will add a new access to US 150 betweenLawrence Banet Road and Luther Road. The new access will be limited to left-in,right-in, and right-out only. There will be no cross traffic allowed at this access.There will be minimal impacts on US 150 and the intersections of US 150/LawrenceBanet Road and US 150/Luther Road from this new access. The new access couldpossibly improve operations at the existing intersections by providing traffic anotherlocation to enter and exit the highway.c. US 150 and Luther RoadUS 150 and Luther Road currently operates at acceptable levels. Choosing not toperform any capacity improvements will result in the intersection operating at LOS Dduring the AM and PM peak hour. The left-turn lanes operate at LOS EThis intersection will not require any major improvements to operate at acceptablelevels. If the current protected only left turn phasing could be changed to protectedpermittedphasing the left-turn movements would operate at LOS A. Because of thehigh speed on US 150, however, it is not recommended that the left-turn phasing bechanged unless travel speeds can be reduced.Traffic volumes suggest that to allow for acceptable vehicular operations,pedestrians should only cross to the median of US 150 during the minor roadphases. To allow for this, sufficient refuge space should be provided for pedestriansin the median of US 150.d. US 150 and Paoli PikeUS 150 and Paoli Pike currently operates at acceptable levels. Choosing not toperform any capacity improvements will result in the intersection operating at LOS Fin the PM peak hour. Several movements operate at LOS F during the PM peakhour.The intersection will have to be reconfigured to adequately accommodate theprojected traffic. The westbound Paoli Pike approach should be reconfigured to havePrepared by Strand Associates, Inc. ® 4-9KRH:pll\S:\@SIECO\001--050\046\008\Wrd\Thoroughfare Plan\Draft 07-19-07\S4-Alternative Evaluation 07-19-07.doc\072007
