BACKGROUND INFORMATION: Tokay Street and Washington Street - The intersection of Tokay Street and Washington Street has been studied based on our observation of increasing accidents and a recent citizen request for service. Currently, Washington Street traffic is controlled by stop signs at Tokay Street. Tokay Street traffic is not controlled. Accident history for the period of over three -and -one-half years from 2000 to the present indicates that there has been an increase in failure -to -yield accidents at this intersection each year (see Exhibit B). These accidents occur when drivers on Washington Street fail to yield to Tokay Street traffic after stopping at the stop sign. Recent traffic volume counts indicate approximately 5,010 vehicles per day (vpd) enter the intersection from Tokay Street and 1,155 vpd enter the intersection from Washington Street. Land use adjacent to the intersection are all single-family residences. A field review of the intersection indicates that parking demand on Tokay Street in the vicinity of Washington Street is relatively high. These parked vehicles create visibility problems for drivers entering Tokay Street from Washington Street. A particular problem observed during the field review was drivers being unable to see westbound vehicles on Tokay Street while stopped southbound on Washington Street due to a pickup and trailer that typically park at the corner. Accident reports also indicate the majority of the collisions that occurred at this intersection (70%) involved vehicles traveling in these directions. Caltrans guidelines are used when considering the installation of multi -way stops. These guidelines consider accidents correctable with the installation of a multi -way stop, as well as vehicle and pedestrian volumes. The guidelines also recommend that traffic volumes be about equal on the intersecting streets. When installed at the intersection of high volume and low volume streets, drivers on the high volume street tend to disregard the stop sign due to the lack of cross street traffic. The minimum recommended traffic split is 60%140%. APPROVED: " ' R-Ftynn, City Manager GTokayWashi ngton_LiveOakWay.doc 12/512003 Adopt Resolution Amending Traffic Resolution 97-148 Approving Converting the Traffic Control at the Intersection of Tokay Street and Washington Street from a Two -Way Stop to a Multi -Way Stop and Approving the Installation of Stop Signs on Live Oak Way at Sweetwood Drive December 17, 2003 Page 2 Based on these guidelines, the number of correctable accidents occurring at the intersection are sufficient to consider a multi -way stop control; however, the traffic volume split of 80%120% is not ideal for a multi -way stop (Exhibit C). In addition, the problem at this intersection appears to be mostly related to visibility problems created by parked vehicles. When visibility problems exist, we typically recommend eliminating street parking to improve visibility. However, because parking demand is high in this area, eliminating parking will displace vehicles into other neighborhood areas, which is likely to create problems with nearby residents. Staff recommends that City Council approve converting the traffic control at this intersection from a two-way stop to a multi -way stop, as shown on Exhibit A. Two marked pedestrian crosswalks are recommended to be installed across Tokay Street at Washington Street. Live Oak Way and Sweetwood Drive - The intersection of Live Oak Way and Sweetwood Drive is a four -legged intersection, with the south leg being a cul-de-sac. There are no traffic controls at this intersection. Based on the Department's best practice, if the overall layout of the development is such that cross traffic would be infrequent, the intersection may be considered a three-legged intersection for traffic control purposes. Three-legged intersections in residential subdivisions are seldom controlled since the terminating street must yield before entering the through cross street. Although cross traffic in and out of the cul-de-sac on Live Oak Way is infrequent, due to the relatively long appearance of the cul-de-sac while traveling south at the intersection, some drivers may be unaware of the need to yield to Sweetwood Drive traffic. There has been only one right-angle accident at this intersection in the past three-year period. Staff considered a yield control; however, our field review of the intersection revealed that existing landscaping at the corners affects the ability of drivers on Live Oak Way to see approaching vehicles on Sweetwood Drive. A Safe Approach Study was performed, and it was determined that the landscaping affected visibility to the point a stop control is recommended. Based on these factors, we recommend that City Council approve the installation of stop signs on Live Oak Way at Sweetwood Drive, as shown on Exhibit A. FUNDING: Street Maintenance Account The cost to convert the traffic control from a two-way stop to a multi -way stop at Tokay Street and Washington Street is approximately $650. The cost for the installation of two stop signs and legends at Live Oak Way and Sweetwood Drive is approximately $280.
