• Mr. Stephen Rohlf December 27, 1993 Page Two • The number of semi vehicles making this left turn onto east TH 10 is significantly lower than the vehicles that make a right-hand turn utilizing the existing acceleration lane and go westbound on TH 10. The majority of the vehicles making a westbound right turn movement would also be loaded and would take a longer length to accelerate up to highway speed. There is no clear, concise analysis that can be applied to this situation to determine whether or not an acceleration is needed. We have concerns that constructing an acceleration lane in this location would be somewhat out of the norm. Typically, acceleration lanes are on the outside of the highway, much like the westbound lane is. We do have some concerns that constructing one on the inside may lead to confusion to the motoring public and could create safety issues above and beyond those trying to be corrected by such an installation. It is not clear to us from the information we have been able to gather and analyze that there clearly is a need for one at this point in time. We would recommend at this time that an acceleration lane not be constructed but that the situation continue to be monitored and reviewed on an ongoing basis. One other consideration that may be appropriate in the future would be consideration of signalizing the intersection rather than constructing an • acceleration lane. There are warrants for traffic signals based on the delay of the side street. Certainly the low volume of traffic on 165th would never meet signal warrants based on total traffic volumes. However, the warrants for interruption or delay on the minor leg of the intersection may be met now or in the future. If you have any additional questions or would like us to do more work on this issue, please call. Sincerely, MSA, CONSULTING ENGINEERS e2L 2ee--/4-0 Terry J.-Maurer, P.E. TJM:tp 000-2710.dec •
