W/SPEEDING: 2 PREDOMINATE: Lost control, Rear End, Sideswipe HBD, DRUNK, H&R: 0 ACCIDENT RATE: 0.59 ACCIDENTS PER MILLION VEHICLE MILES DISTRICT 7 AVERAGE: 1.76 ACCIDENTS PER MILLION VEHICLE MILES EXISTING SPEED ZONE – 45 MPH PROPOSED SPEED ZONE – 45 MPH The 85th percentile speed suggests a speed zone of 50 mph would be appropriate. The roadway is frequently used by bicyclists, creating the potential for significant conflict with vehicles. The sidewalk is non-continuous in the area and Peninsula High School is adjacent to the roadway. Based on these factors and CVC Section 627, it is appropriate to apply a 5 mph reduction from the 85th percentile speed in order to establish a reasonable and safe speed limit. COMMENTS
