BACKGROUND At the November 6, 1991 meeting, a petition was submitted to City Council from residents of Tokay Street requesting that the existing 35 mph speed limit between Lower Sacramento Road and Mills Avenue be reduced tc at least 25 mph (Exhibit A). Speed limits are established following guidelines outlined by the State of California, Department of Transportation, and the California Vehicle Code. The 35 mph speed limit on Tokay Street was determined using these guidelines. This survey was approved by City Council on June 19 of this year (Exhibit B). Arbitrarily reducing speed limits below these guidelines would result in a speed limit that is not enforceable by the use of radar. The 25 mph posted speed limit that existed prior to this survey was not radar enforceable. An earlier speed zone survey prepared by staff in 1989 was postponed by Council until the Apple Orchard development was completed. The speed limit proposed in 1989 was also 35 mph (Exhibit C). To check present vehicle speeds, an electronic counting device was placed on Tokay Street east of Lower Sacramentc Road. The results of this survey are shown on the attached table and graph (Exhibit D). By definition, per state guidelines, 85 percent of drivers drive a reasonable speed thus the limit is set at the nearest 5 mile-icrement below this "85th percentile" This "rounding down" can increase the percentage over the limit. The results of the speed survey on Tokay Street indicates that approximately 25% of the drivers, traveling in both directions, were exceeding the posted speed limit. Less than 1% were exceeding 40 mph. For comparison reasons, speed data was also collected on Mills Avenue north of Lodi Avenue (Exhibit E), Aithough Mills Avenue is slightly wider than Tokay Street, the posted speed limit is also 35 mph. The results of the speed survey on Mills Avenue indicate that approximately 20% of the drivers, traveling -i both directions, were exceeding the posted speed limit. Staff has no reason to believe that speeds on other collector streets are not similar. APPROVED. THOMAS A. PETERSON City Manager J cc•t Tokay Street, Lower Sacramento Road to Mills Avenue - Speed Study December 4, 1991 Page 2 DISCUSSION/RECOMMENDATION In comparing the speed zone surveys performed on Tokay Street in 1989 and 1991, staff found vehicle speeds were similar. This indicates that changing the 25 mph speed limit signs to 35 mph speed limit signs was had little or no effect on vehicle speeds. This is consistent with research showing that drivers' speed is influenced more by the appearance of the roadway itself and prevailing traffic conditions rather than by the posted speed limit. NMm speed limits are established, criteria used to reduce speed limits below the critical speed are reviewed. This criteria includes conditions that are not readily apparent to drivers, such as the accident rate. Arbitrarily lowering speed limits without the support of this criteria would result in a speed limit not enforceable by the use of radar. Although there is apparently sorne concern that the 35 mph speed limit on Tokay Street is too h gh, it is the appropriate speed limit per state guidelines, is radar enforceable and is comparable to other collector streets with residential frontage. In order to have an recommend that the zone survey is also enforcement speed data enforceable speed limit on Tokay Street, staff does not speed limit be arbitrarily reduced. Performing another speed not recommended at this time. Staff feels that increased is neccessary to reduce the number of speeding drivers. The electronic collected for this study will be sent the Police Department. FUNDING: None Ja k.L.

This reduction was requested by petition from residents of Tokay Street. Because this 30 mile per hour speed limit is not supported by an engineering and traffic survey, it is not enforceable by radar per Vechile Code Section 40802 (see attached survey).
