Individual cycle failures begin to appear. <br /> Operations with longer delays due to a combination of unfavorable <br /> D progression, long cycle lengths,and high volume-to-capacity(V/C) ratios. > 35.0 to 55.0 <br /> Many vehicles stop and individual cycle failures are noticeable. <br /> Operations with high delay values indicating poor progression, long cycle <br /> E lengths,and high V/C ratios. Individual cycle failures are frequent > 55.0 to 80.0 <br /> occurrences. <br /> F Operations with delays unacceptable to most drivers occurring due to > 80.0 <br /> over-saturation, poor progression,or very long cycle lengths. <br /> Source:2000 Highway Capacity Manual. <br /> Unsignalized Intersections <br /> The level of service method identified by the City of Pleasanton General Plan for unsignalized <br /> intersections is the method described in the HCM 2000. This method bases unsignalized <br /> intersection operations on the vehicular control delay. The City of Pleasanton General Plan <br /> applies LOS D as the performance standard at most intersections. <br /> Control delay includes initial deceleration delay, queue move-up time, stopped delay, <br /> acceleration delay. The control delay for unsignalized intersections is calculated using the <br /> Synchro 9 analysis software and is correlated to a LOS designation as shown in Table A-2. For <br /> side-street stop controlled intersections, the delay of the worst approach is recorded as the <br /> result. For all-way stop controlled intersections, the whole-intersection average delay is recorded <br /> as the result. <br /> Economic& Planning Systems, Inc.
