LOS ALTOS CITY COUNCIL TO CONSIDER SPEED LIMIT CHANGES
Los Altos, Calif. – July 29, 2013 – The California Vehicle Code (CVC) requires local municipalities to re-evaluate non-statutory speed limits every five to ten years. The requirements set forth by the CVC and California Manual for Uniform Traffic Control Devices (CA MUTCD) maintain that speed limits must be based on valid traffic surveys in order to be enforceable by radar equipment.
Traffic surveys measure the speeds at which a random sampling of 100 motorists are driving on a given day. The speed limit is then determined by rounding to the nearest 5 mph increment of the 85th percentile speed. There are circumstances that allow a traffic engineer to further round down to the nearest 5 mph increment, such as road abnormalities or other road hazards that may not be visible to motorists.
The Los Altos City Council will hear a staff report at its August 13, 2013 meeting that will recommend speed limit increases on a number of road segments throughout the City. The last traffic survey conducted in the City of Los Altos was in 2007 and included the evaluation of 42 street segments. A total of 23 road segments were recently surveyed by the City, based on those findings, 19 segments have been recommended for raised speed limits, while four are recommended to maintain their current posted speeds.
In order to keep City streets safe from speeders, Police must be able to enforce speed limits. The use of radar equipment for speed enforcement is widely considered the safest and most effective method to detect and cite speed violators. While the City Council can set the speed limits as low as it desires, unless the posted speed limit is based on a valid traffic survey, Police cannot use radar enforcement.
The ‘pace method’ is an alternative speed enforcement method, which would require an officer to position his or her vehicle behind the violator to measure speed by following at a fixed distance. This can require maneuvering in and out of traffic and cutting off motorists to maintain pace. This method is not practical for the City of Los Altos due to the majority of City streets consisting of two lanes only.
Based on the recent traffic survey, 14 road segments are recommended to be raised from 25 mph to 30 mph, one road segment is recommended to be raised from 25 mph to 35 mph, and four segments are recommended to be raised from 30 mph to 35 mph. See the table below for more information. Adoption of an Ordinance to raise these speed limits will allow legal and safe speed enforcement for all the designated speed zones in the City of Los Altos.
