W/SPEEDING: 7 HBD, DRUNK, H&R: 0 ACCIDENT RATE: 0.81 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. However 7 of the 9 reported accidents involved vehicles traveling at an unsafe speed, indicating that motorists are NOT using due caution. Also, Robert Ryan Park is located on the west side, creating the potential for significant pedestrian and bicycle conflict with vehicles. Considering 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
