Saticoy & Wells Community Plan and Code EIRSection 4.15 Traffic and Circulationb. Existing Traffic Volumes and Levels of Service. Table 4.15-1 and Figure 4.15-1illustrate the intersections that were analyzed during the A.M. and P.M. peak hours as part ofthis EIR.Table 4.15-1Study Area Intersections1.

Saticoy Ave/Darling RoadBecause traffic flow on urban arterials is most constrained at intersections, detailed traffic flowanalyses focus on the operating conditions of critical intersections during peak travel periods.In rating intersection operations, “Levels of Service” (LOS) A through F are used, with LOS Aindicating free flow operations and LOS F indicating exceedance of road capacity. IntersectionLevel of Service criteria are shown in Table 4.15-2.The City considers LOS E acceptable at freeway interchange intersections and considers LOS Dacceptable at the “Principal Intersections” within the City. Principal intersections areintersections that are regularly monitored by the City as a gauge of the operation of the City’scirculation system. The City does not have a level of service standard for non-principalintersections, except for those that are located on the CMP network, at which the CMP level ofservice standard of LOS E is applicable.Levels of service for signalized intersections were calculated based on the “IntersectionCapacity Utilization” (ICU) methodology parameters outlined in the City's 2005 VenturaGeneral Plan EIR. Levels of service for the unsignalized intersections were calculated using theHighway Capacity Software (HCS), which implements the Highway Capacity Manual (HCM)methodology to determine the total delay in seconds experienced by vehicles at a stopcontrolledintersection, which is then related to a level of service. Table 4.15-3 lists the studyarea intersections and their corresponding A.M. and P.M. peak hour levels of service and theICU for existing traffic conditions.As indicated in Table 4.15-3, all of the intersections considered in this traffic study operate atLOS C or better under existing conditions, which is considered acceptable based on the City’slevel of service standards.c. Transit. Transit service is provided by Gold Coast Transit (formerly SCAT), with sixroutes operating on both weekdays and weekend days within the Project Area. Additionaltransit is provided by the Ventura Intercity Service Transit Authority (VISTA), which providesintercity service for the County of Ventura. Transit service routes within the Project Area areCity of Ventura4.15-3
Saticoy & Wells Community Plan and Code EIRSection 4.15 Traffic and CirculationTable 4.15-2Intersection Level of Service DescriptionsLOSDescriptionDelay perVehicle(sec.)ICU RangeABCDEFLOS A describes operations with low control delay, up to 10seconds per vehicle. This LOS occurs when progression isextremely favorable and most vehicles arrive during the greenphase. Many vehicles do not stop at all. Short cycle lengths maytend to contribute to low delay values.LOS B describes with control delay greater than 10 and up to 20seconds per vehicle. This level generally occurs with goodprogression, short cycle lengths, or both. More vehicles stop thanthe LOS A, causing higher levels of delay.LOS C describes operations with control delay greater than 20 andup to 35 seconds per vehicle. These higher delays may result fromonly fair progression, longer cycle lengths, or both. Individual cyclefailures may begin to appear at this level. Cycle failure occurswhen a given green phase does not serve queued vehicles, andoverflows occur. The number of vehicles stopping is significant atthis level, though many still pass through the intersection withoutstopping.LOS D describes operations with control delay greater than 35 andup to 55 seconds per vehicle. At LOS D, the influence ofcongestion becomes more noticeable. Longer delays may resultfrom some combination of unfavorable progression, long cyclelengths, and high V/C ratios. Many vehicles stop, and theproportion of vehicles not stopping declines. Individual cyclefailures are noticeable.LOS E describes operations with control delay greater than 55 andup to 80 seconds per vehicle. These high delay values generallyindicate poor progression, long cycle lengths, and high V/C ratios.Individual cycle failures are common.LOS F describes operations with control delay in excess of 80seconds per vehicle. This level, considered unacceptable to mostdrivers, often occurs with oversaturation, that is, when arrival flowrates exceed the capacity of lane groups. It may also occur at highV/C ratios with many individual cycle failures. Poor progressionand long cycle lengths may also contribute significantly to highdelay levels.< 10 0.00 – 0.6010 - 20 0.61 – 0.7020 - 35 0.71 – 0.8035 - 55 0.81 – 0.9055 - 80 0.91 – 1.00> 80 > 1.00Source: Highway Capacity Manual 2000, Transportation Research Board, National Research Council.4.15-4City of Ventura
