Calculation forms are provided in Appendix D. The key intersections will operate acceptably. From the above analyses, it is concluded that restricting the US287/Colland intersection to right-in/right-out operation will not cause unacceptable operation at any of the key intersections in the short range (2006) or long range (2020) futures. The most significant impact of this action would be that some traffic movements will be forced to have a slightly longer distance to travel. The increase in travel distance for the northbound left turn at the US287/Colland intersection would be approximately 800-1000 feet. The increase in travel distance for the westbound left turn at the US287/Colland intersection would be approximately 2300-2500 feet. However, the travel time for this movement may be shorter, in consideration of the delays that would be encountered at the US287/Colland intersection if it allowed these westbound left turns. i In MEMORANDUM co LO o CO TO: Rod Jones, Quadrant Properties Co ' Bill Bates, King Soopers oLinda Ripley/Rachel Linder, VF Ripley a: CD Nick Haws, Northern Engineering Sheri Wamhoff,.City of Fort Collins o U Eric Bracke, Fort Collins Traffic Engineer X Tess Jones, CDOT o Li Roxann Hayes, Larimer County Engineering a w FROM: Matt Delich O J C.0 DATE: January 15, 2003 w o N M SUBJECT: Longview Marketplace at Shenandoah Transportation Impact Study e to staff comments /1 z C_Re (File: 0243ME02) > CD z Uj o This memorandum provides information and analyses pertaining 0 = to various staff comments regarding the US287/Colland Drive N r a intersection. Staff indicates that full deceleration and storage for N the northbound left -turn on US287 approaching Avondale is not N possible without_ a variance. This is acknowledged. In light of this, analysis of the repercussions of restricting the US287/Colland intersection to right-in/right-out was requested. Under this turn restriction, certain traffic volumes would need to be reassigned. Peak hour traffic counts were obtained at the US287/Colland intersection and the Carpenter/Colland intersection in January 2003. Raw traffic data is provided in Appendix A. Figure 1 shows these traffic counts along with the peak hour traffic at the US287/Carpenter intersection from the "Shenandoah Commercial Transportation Impact Study," November 2002. Table 1 shows the peak (L hour operation at each of these intersections. Calculation forms are provided in Appendix B. These intersections operate acceptably, Q. z except for the westbound minor street left turn at the US287/Colland Fr intersection, which operates at level of service E during the z afternoon peak hour.
