This traffic analysis evaluates the traffic control and operations at the intersection of Tustin Ranch Road at Adams Drive/Greenway Drive based on existing traffic volumes, current intersection lane geometries, and the traffic signal warrants contained ui the California Manual On Unifor°m Traffic Control Devices (MU!'CD), dated September 26, 2006. PROJECT LOCATION The study intersection of Tustin. Ranch Road at Adams Drive/Greenway Drive is generally located north of Irvine Boulevard between Redliill Avenue aiid Jamboree Road in the City of Tustin, California. Figure 1, located at the rear of this letter report, presents a Vicinity Map, which illustrates the general location of the study intersection and the surrounding street system.

On-street parking is prohibited on both sides of this arterial. Adams Drive/Greenway Drive is a two-lane undivided roadway (one lane per direction). At the study intersection, the eastbound aad westbound approaches provide a shared left/through/riglrt-turn lane. The posted speed limit on Adams Drive/Greenway Drive is 25 mph east of Tustin Ranch Road and 25 mph (prima facie) west of Tustin Ranch Road. (fin-street parking is prohibited on both sides of this roadway. Tlus study intersection is culrelltly controlled by a two-way stop. Eastbound tl•affic and westbound traffic on Adams Drive/Greenway Drive is controlled via a stop sign, while northbound traffic and southbound traffic on Tustin Ranch Road is uncontrolled. In addition to the aforementioned field inventory, brief field observations were made at the lcey study intersection. Field observations were conducted in the morning to observe overall intersection operations and pedestrianz activity. Based on the field observations, some velvcles waiting to turn out of Adams Drive and/or Greenway Drive had to wait for adequate gaps on Tustin Ranch Road. Further, based on field observations, no conditions were readily apparent that indicated any pedestrian related safety issues. EXISTING TRAFFIC VOLUMES Existing daily and peals hour traffic counts were conducted at the intersection of Tustin Ranch Road at Adams Drive/Greenway Drive on a typical weekday. Daily approach counts were conducted on each approach leg of the shady intersection on Wednesday, November 28, 2007. Peak hour, intersection turning movement counts were also eondu.cted on the same day during the morning and evening peak hours (7-9 AM and 4-6 PM, respectively). The txafflc counts, provided by Raf q & Associates, were conducted by Traffic Data Services, Inc. Tigure 3 gl•aplvcally presents the existing peak hour and daily approach traffic voltunes at the lcey study intersection. Appe~xrlix fi, attached at the rear of this letter report contains the detailed manual turning movement counts and daily approach counts at the key study intersection. ~ ~?qi>ry~$ig?957 ;Sigunl N'nrrant G~alnnliO~i~Tuflin R:mrh Foal ui Admus-Gi eenwn~"'x~7lU;un Ranch.Adams Trxil'ic tiiuual N'nrrrun Lel ler lr l0-Ukddr 1VLr. Timor Rafiq June 10, 2008 Page 3 SICI~IAL V4~ARRANT EVAL,UATIOlOi Overview Traffic signals exert a sigiuficant influence on vehicle and pedestrian traffic flow. Traffic signals are designed to draw the attention of drivers approaching an intersection. Their main purpose is to safely assign the right-of--way to various tY•affic movements, and thus, may be notably advantageous. Some advantages include: ^ Provide for the orderly movement of traffic, ^ Can increase the traffic handling capacity of the intersection, ^ Reduce the frequency of certain types of accidents (especially the right angle type), ^ Can be coordinated to provide for continuous, or nearly continuous rnovement, of traffic at a definite speed along a given route, and ^ Permit minor street traffic, vehicular or pedestrian, to enter, or cross, continuous traffic on the major street. However, improper or unwarranted traffic control signals may also cause disadvantages. In some circumstances, traffic signals inay cause more problems than it solves. Some disadvantages include: ^ excessive motorist delays, ^ Disobedience of the signal indications, ^ Increased accident frequency (rear-end collisions may increase), and ^ Reduce intersection capacity. MUTCD Policy/Criteria The justification for the installation of a traffic signal at an intersection is based on several factors. A set of factors includes the warrants set forth in Part 4 (Highway Traffic Signals) of the California MUTCD, dated September 26, 2006. The above reference material list eight parameters, which help to determine the necessity of a traffic signal at a1n intersection. The warrants consider colnditialns involving traffic volumes on the intersecting streets, the difficulty of vehicles or pedestrians on a side street crossing a major street, the number of recorded accidents that may be correctable by a traffic signal and special conditions that may be improved by a traffic signal. Other factors taken into consideration for the installation of a traffic signal include: approach conditions, driver confusion and comfort level, safety conditions, future land uses, and other indications demonstrating the need for right of way assignment beyond that which could be provided by stop signs. ~ ~iiY_ i, ; ~ ~ , ~ `i~ r ,~~i I ~ .._ c _ l)2~~h9~'.OR^_967eSignnl 1Vmr,~nl IivBhi;nWU\'I'uslin Itnuch Ito~J ur :\danzs--Ciicem~~ask'~4~7 Tu.pn Rnnc3r.~ld;pus TmOie Sr!nul 14'nrrnnt I_a[lar h-Ili•I~YAi~~t Mr. Timor Rafiq June 10, 2008 Page 4 Traffic Sageaa! Warrant Analysas The following traffic signal warrants were applied to the intersection of Tustin Ranch Road at Adams Drive/Greenway Drive: ^ Warrant No. 1: Eight Hour Vehicular Volume ^ Warrant No. 2: Four Hour Vehicular Volume ^ Warrant No. 3: Peale Hour ^ Warrant No. 4: Pedestrian Volume ^ Warrant No. S: School Crossing ^ Warrant No. 6: Coordinated Signal System ^ Warrant No. 7: Crash Experience Warrant ^ Warrant No. 8: Roadway Network Table 1, located at the rear of this letter repoz-t following the figures, provides a summary of the results of the traffic signal wan-ant analysis conducted at the u~tersecti_on of Tustin Ranch Road at Adams Drive/Greenway Drive. As indicated above, each warrant analyzes a different traffic condition and any one satisfied warrant may be used as a basis for installing a traffic signal. As shown in Table 1, based on the existing traffic volumes and ctu-rent intersection geometries, the study intersection did not satisfy Signal Warrants No. 1, No. 6, No. 7 and No. 8. However, the study intersection did satisfy Signal Warrants No. 2 and No. 3. Therefore, a traffic signal at the intersection of Tustin Ranch Road. at Adams Drive/Greenway Drive should be considered. Appendix B contains the detailed traffic signal warrant worksheets. Figure 4 presents the collision diagram for the key study intersection associated with Signal Warrant No. 7. INTIaIItSI•JCTION OPCRATIONS ANALYSIS In addition to the aforementioned traffic signal warrant analysis, a level of service analysis was conducted at the intersection of Tustin Ranch Road at Adams Drive/Greenway Drive using the N_ighu~ay Capaczty Manual. ?000 (I~CM 2000) unsignalized methodology. Table 2 summarizes the results of the existing level of service analysis. Review of Table 2 uidicates that both the eastbound and westbound approaches of the Tustil~ Ranch Road at Adams Drive/Greenway Drive intersection currently operate at LOS F dtuing the AM peak hour. During the PM Peale hour, the eastbound approach operates at LGS C and the westbound approach operates at L.f]S F. Based on City of Tustin level of service standards (L®S D or better) this intersection currently operates at an unacceptable level of service during the AM and PM peak hours. ,y42nu9`2PK?4(TSignal Wnr~xni l;vatua4un',Tt~slin R:uu:h Ruud at :~danis-Cif e~mvx}•\29x7 7usun l:anch-,~dnms IYnIYI~ Siyunl Wprrnm LeLLer it 10-OS.dn~• Appendix C contains the HCM/LOS calcid.ations far the intersection of Tustin Ranch Road at Adams Drive/Greenway Drive. COI~CLUSIOAI Based on the aforementioned traffic signal warrant analysis for the intersection of Tustin Ranch Road at Adams Drive/Greenway Drive, Signal Warrants No. 2 and No. 3 are satisfied. In addition, based an the intersection operations analysis, which indicates an unacceptable level of service for the eastbound acid westbound approaches during the AM and/or PM peak hours, the installation of a traffic signal is justified..

The Board of Directors for the Malaga Community Association has requested I contact you regarding a review by your department for the possible installation of a traffic signal on Tustin Ranch Road, at Adarns Drive. The Boazd is very concerned about safety in this area due to the high volume of traffic and the speed of vehicles traveling on this busy public street. The Association would be appreciative of any assistance rendered in this issue, which will provide safety to a large area of the community.
