Ms. Lindy Chan Page 9 October 27, 2017 <br />As summarized in Table 4, the intersection would operate acceptably with a traffic signal, while operation with the <br />roundabout would result in deficient operation during the a.m. peak hour and acceptable operation during the <br />p.m. peak hour. <br />Table 4 – Existing and Alternative Control Intersection Peak Hour Intersection Levels of Service <br />Control Scheme <br /> El Camino Real/Redwood Avenue-Main Street <br />AM Peak Hour PM Peak Hour <br />Delay LOS Delay LOS <br />Existing Configuration <br />El Camino Real/Redwood Avenue-Main Street 0.0 A 0.1 A <br /> Southwestbound (Main Street) Approach 12.7 B 16.8 C <br />Signalized <br />El Camino Real/Redwood Avenue-Main Street 50.9 D 31.6 C <br />Roundabout <br />El Camino Real/Redwood Avenue-Main Street 59.5 E 42.1 D <br />Notes: Delay is measured in average seconds per vehicle; LOS = Level of Service; Results for minor approaches to two-way <br />stop-controlled intersections are indicated in italics; Bold text indicates deficient operation <br />Preferred Alternative Traffic Operation <br />A preferred alternative was developed that would balance mobility for all users of El Camino Real. The following <br />summarizes the recommended improvements that were incorporated into the analysis of the Preferred <br />Alternative. <br /> The corridor was analyzed assuming the signalized intersections were operating under an optimized <br />signal timing coordination scheme. <br /> The following right-turn lanes were removed from the El Camino Real approaches: <br />o El Camino Real/Brewster Avenue (Northbound and Southbound) <br />o El Camino Real/James Avenue (Southbound) <br />o El Camino Real/Jefferson Avenue (Northbound) <br />o El Camino Real/Maple Street (Northbound) <br />o El Camino Real/Roosevelt Avenue (Southbound) <br /> The left-turn phasing on the westbound and eastbound James Avenue approaches at El Camino <br />Real/James Avenue was modified from permitted phasing to protected phasing. <br /> The El Camino Real/Redwood Avenue-Main Street was analyzed as a four-legged signalized intersection, <br />with left turns prohibited on northbound and southbound El Camino Real. <br />The following Level of Service, travel time, and corridor delay summaries evaluated the effects of the <br />recommended improvements as described above. As summarized in Table 5, the intersections would operate <br />acceptably at similar Levels of Service as under existing conditions with the implementation of the preferred <br />alternative.
