Richard Edgar Subj: Stop Signs - 6th and B Street Gentlemen: The Boys' Club of Tustin is experiencing a great increase in foot, b~csc~e, and skateboard traffic by youth's traveling to our facility via the 6th Street route. Pre~ently the intersection of 6th and "B" Street has stoo signs on 6th with "B" street havins the right of way. Thls seems to be in reverse since 6th Street has the greatest traffic load, both vehicular and pedestrian; while "B" Street travelling south is a dead end. To orotect our children, it is requested that: A. Stop signs~ be o!aced on :'B" Street ~nd removed from 6th Street. B. OR, stop signs be placed on "B°' Street making the intersection a 4 way stop. l'3e believe that anyone familiar with this inter- section would quickly substantiate the validity of our recuest. ~$e look forward toga favorable positive response. Sincerely, Chairman - Building~ ond Grounds Committee TH:th DATE: JANUARY 28, 1981 Inter-Corn TO: BOB LEDENDECKER, DIRECTOR OF PUBLIC WORKS/CITY ENGINEER FROM: NORM HOWER, TRAFFIC ENGINEER SUBJECT:SIXTH STREET AND "B" STREET INTERSECTION The intersection of Sixth Street and "B" Street has been studied in reference to the Boy's Club of Tustin'$ concerns as you requested. Traffic volumes approaching the intersection were counted with the higher volume (1,495) being on Sixth Street and the lower (950) on "B" Street, as indicated in the letter from the Boy's Club. The intersection could not meet the warrants for 4-way stop control during any hour of the day, as indicated on the attached volume chart. There has not been an unusual amount of accidents at this intersection; the last reported accident being in October of 1977 which was a vehicle vs. vehicle accident. On January 22, i981, the intersection was observed from 7:00 A.H. to 5:00 P.M. Unfortunately, the clothing store on the southeast corner was having a sale which resulted in an unusual amount of vehicular traffic, pedestrian traffic and parking in the intersection and on each leg within 500 to 600 feet of the intersection. The total number of pedestrians crossing all legs of the intersection was 249 with 20 of these appearing under the age of 14 and 7 of these crossed with adults going to the sale. The clothing sale appeared to be the destination of almost all of the adult pedestrians. A large number of pedestrians crossed outside the intersection area. A total of 44 bicyclists crossed "B" Street and 7 crossed Sixth Street. Out of the 44 crossing "B" Street in both directions, only two small children stopped for the stop sign and these then walked their bicycles across as pedestrians. The other 42, both children and adults, did not bother to stop. In addition, there were several mopeds that did not stop. There were 10 bicyclists crossing "B" Street that appeared under the age of 14 and 5 crossing Sixth Street. Most of the remaining bicyclists appeared to be of high school age. While watching the intersection two near accidents were observed. Both of these resulted from a westbound vehicle on Sixth Street not stopping and nearly hitting a vehicle on "B" Street. Not stopping is characteristic of unwarranted stop installations~ Parked vehicles can sometimes impair vision in those areas where there are no vision zones and some parking should be removed. SIXTH STREET AND "B" STREET INTERSECTION JANUARY 28, 1981 PAGE 2 It is recommended that a pedestrian count be made at some time when the unusual conditions do not exist so that a true indication of pedestrian activity can be obtained. It is also recommended that the existing stop remain and no new stops be installed due to the intersection not meeting warrants. Also, parking should be removed where needed for vision zones. It would appear that some enforcement is needed at this intersection, especially in regards to bicycles.
