3. STREET: PVDE Traffic Engineering Survey City of Rancho Palos Verdes LIMITS: Miraleste Dr – City Limit (RHE) PROPOSED SPEED ZONE – 30 MPH Comments: This segment of roadway is characterized by one travel lane in each direction with substantial fronting single-family residential development and numerous sharp horizontal curves. In addition to driveway access, there are also several intersecting roadways, both public and private. It mainly differs from the segment to the south by having more entering and exiting vehicular traffic, as well as greater pedestrian traffic due to Miraleste Intermediate School and the library. This segment has more extensive pedestrian facilities, typically AC sidewalk and pathways, than the segment to the south. The California Manual of Uniform Traffic Control Devices (MUTCD), which is authorized by the California Vehicle Code (CVC) as the legal procedure for establishing speed zones, states that speed zones should not be less than 0.5 miles in length (see pages 2B-8 and 2B-10). Since this segment is approximately 2.20 miles long, it is a valid candidate for establishing a speed limit that differs from adjacent segments. One radar speed measurement was taken for this portion of the segment, with the 85th percentile speed suggesting that a speed zone of 35 mph would be appropriate. However this roadway is very narrow, has limited shoulder area with no defined bike lane and is extensively used by bicyclists. This segment is also regularly used by equestrians and pedestrians. This non-vehicular traffic, located in close proximity to the travel lanes, creates the potential for substantial conflict with vehicles. Furthermore, there is severely limited visibility for vehicles exiting the side streets and driveways when viewing traffic on Palos Verdes Drive East due to the horizontal curvature. A review of the reported accident history revealed that 39% (11 of 28) of the accidents occurring during the 2-year period ending July 31, 2007 involved unsafe speed. Considering these factors and CVC Section 627, which specifies that pedestrian and bicyclist safety be considered when determining a speed limit, it is appropriate to apply a 5 mph reduction from the 85th percentile speed in order to establish a reasonable and safe speed limit. Therefore, it is recommended that a 30 mph speed zone be established for this segment.
