Proposed MARINWOOD TRAFFIC ENHANCEMENTS TURN RESTRICTIONS SPEED LIMITS IMPROVEMENTS
TURN RESTRICTIONS SOUTHBOUND US 101 - MILLER CREEK ROAD OFF RAMP MARINWOOD AVE./MILLER CREEK RD. INTERSECTION 6:00 am to 10:00 A.M.
SPEED LIMITS MILLER CREEK ROAD LAS GALLINAS AVENUE BLACKSTONE DRIVE
Raise the Speed Limit? But… why??
Two different kinds of speed limits • Maximum • Prima Facie
Maximum Speed Limits • Written into state law • No justification (survey) needed to enforce w/ radar • State maximum for different roadway designs • 55: Max on 2-lane, undivided roads • 65: Max on multi-lane, divided and undivided roads • 70: Max on certain rural freeways in California 22349(a/b) and 22356(b) CVC
Prima Facie Speed Limits • Anything lower than the state maximums require justification • CHP cannot use radar to enforce PF speed limits without justification • Justification is county Engineering and Traffic Survey (ETS) 40802 CVC
Engineering and Traffic Survey • 85th percentile • 85% of vehicles driving this road go this speed or lower • Speed limit is set to nearest 5 MPH increment below 85th percentile speed • Anything lower is a speed trap • CHP must still articulate in court why speed was unsafe for conditions
Why not keep the 25 MPH on Las Gallinas Ave? • CHP cannot enforce a 25 MPH speed limit on Las Gallinas Ave with no ETS • ETS sets safe speed at 30 MPH • ANY radar enforcement would be a speed trap and illegal • Vehicle at 40? CHP can do nothing about it.
Why raise the limit to 30 MPH on Las Gallinas? • 85% of vehicles safely use Las Gallinas Ave at this speed already • Limit would still be 25 at Miller Creek School while children are present • Vehicle at 40? CHP can cite.
