Farmington Rd. to Browning Ave. Browning Ave. to Myford Rd. 40 MPH 40 MPH 40 MPH 45 MPH BACKGROUND: As requested, from the west Myford Road. an engineering and traffic survey has been conducted for Main Street city limits to Bryan Street and Bryan Street from Main Street to The following are the recommended speed limits for the listed section of roadway: RECOMMENDED SPEED LIMITS MAIN STREET ROAD SECTION West city limits to Williams St. Williams St. to B St. "B" St. to Prospect Ave. Prospect Ave. to Newport Ave. Newport Ave. to Bryan Ave. SPEED LIMIT 40 40 30 40 4O BRYAN AVENUE Main St. to Red Hill Ave. Red Hill Ave. to Farmington Rd. Farmington Rd. to Browning Ave. Browning Ave. to Myford Rd. 4O 40 4O 45 The radar study has indicated that the section between B Street and Prospect k Avenue has an 85th percentile of 40 MPH. Due to the narrowing of the lanes, SPEED ZONE - MAIN STREET AND BRYAN AVENUE JUNE 29, 1982 PAGE TWO considerable parking, and pedestrians crossing at various locations other than the intersection, it is recommended that this section be zoned at 30 MPH. The 85th percentile for the section of roadway between Browning Avenue and Myford Road would indicate a posted speed limit of 55 MPH. It is recommended that this section be posted for 45 MPH due to the lack of a shoulder and the large drainage ditch on the north side of the roadway, which would force a stalled vehicle to block the westbound trave) lane and would be unexpected by the motorist. The recommendations for the other sections follow the 85th percentile speeds indicated by the radar survey. These speed zones will provide for the use of radar as an enforcement tool.

A common belief is that posting a speed limit will influence drivers to drive at that speed. The facts indicate otherwise. Research conducted in many parts of this country over a span of several dec3dcs has shovgn that drivers are influenced more by the appearance of the highway itseif and the prevailing traffic conditions than by the posted speed limit. California's Basic Speed Law requires that: "No person shall drive a vehicle upon a highway at a speed greater than is responsible or prudent having due regard for weather, visibility, the traffic on, and the surface and width of the highway, and in no event at a speed which endangers thc safety of persons or property." Under California law, the maximum speed limit for any passenger vehlcla is nc,',,.'. 55 miles per hour. Ail other speed Iimits are called prima facie limits, which "on the ~dC¢' of !t" are safe and prudent under normal conditions. Certain prima facie limits are established by law and incluce the 25 MPH limit in business and residential districts, the !5 SylPH iin',it in alleys, at blind intersections and blind railroad crossings and a part-time 25 MF'H lin~;t in school zones wt~en children are going to and from school. These speeds ~re not posted but all California motorists are required to know these basic 15, 25, a~d 55 per hour speed la~s. Intermediate speed limi[s be[ween 25 and 55 miles per hour may be establ[shed hy local authorities on the basis of traffic engineering surveys. These surge,is ]nc!ude an 2r~alysis of roadway conditions, accident records, and the prevailing speed of prudent dr!'.,e-s. If speed limit signs are posted for a lower limit than is ncederf to sa,rely r~:,_,;: these conditions, many drivers will simply ignore the signs. At the same time, other drivers wi',', stay within the posted limits. This generally increases the conflicts between faster and slower drivers, reduces the gaps in traffic through which crossings could be made safely and increases the difficulty for pedestrians to judge the speed of approaching vehicles. Studies have shown that where uniformity of spe~d i's not mainta:ned, acodents generally increase, I?,', 1 77 u { I Ii Iii iH '~ - , I I t 1 h q~-r~-1'i ~ t ~' [. ~ , i ~ ~ 1 I I ~ i I I ~; Nil I I . t~~ i ilI111 it~"li~l I I I ~ '' , i~ -~ ~ · ' ~ I ' ' _ : ~ ~ -- : ~ , , 4 . ~. _:~_.~-~ ,o ~...~, .... · , ~-~,xx~, :'.. ..........~ - , t ......
