8.B. - Page 137 Ms. Lindy Chan Page 9 October 27, 2017 As summarized in Table 4, the intersection would operate acceptably with a traffic signal, while operation with the roundabout would result in deficient operation during the a.m. peak hour and acceptable operation during the p.m. peak hour.

The following summarizes the recommended improvements that were incorporated into the analysis of the Preferred Alternative. • The corridor was analyzed assuming the signalized intersections were operating under an optimized signal timing coordination scheme. • The following right -turn lanes were removed from the EI Camino Real approaches: o EI Camino Real/Brewster Avenue (Northbound and Southbound) o EI Camino Real/James Avenue (Southbound) o EI Camino Real/Jefferson Avenue (Northbound) o EI Camino Real/Maple Street (Northbound) o EI Camino Real/Roosevelt Avenue (Southbound) • The left -turn phasing on the westbound and eastbound James Avenue approaches at EI Camino Real/James Avenue was modified from permitted phasing to protected phasing. • The EI Camino Real/Redwood Avenue -Main Street was analyzed as a four -legged signalized intersection, with left turns prohibited on northbound and southbound EI Camino Real. The following Level of Service, travel time, and corridor delay summaries evaluated the effects of the recommended improvements as described above. As summarized in Table 5, the intersections would operate acceptably at similar Levels of Service as under existing conditions with the implementation of the preferred alternative.
