Roadway segments included in the Roseville Municipal Code, Section 11.28.010 reflect the most current speed limits adopted by ordinance.
-
The Engineering and traffic surveys associated with each roadway segment are on file in the Traffic Operations office. Should you wish to obtain a copy of a speed survey, please contact our office by calling (916) 746-1300 or emailing us.

The Speed Limit Map indicates the speed limits within the city
based on a color code which is explained on the map legend.
How speed limits are determined
The City of Roseville sets speed limits through an engineering and
traffic survey in accordance with standards set by the State of
California. For streets that carry local traffic only, the speed limit
is set at 25 mph and is not posted.
Below you'll find engineering and traffic surveys for major streets, prepared
and reviewed regularly by the City of Roseville in accordance with the
California Vehicle Code.
Engineering and traffic surveys
measure the actual speeds that drivers travel on a given street.
Certified lidar guns are used to ensure that the measurements are
accurate. To the extent possible, the speed measurements are taken on
days with fair weather, dry pavement, and clear visibility and are taken
at a location not affected by stop signs, parks, schools, curves or
other features that would affect speed. An effort is made to ensure that
the presence of lidar survey equipment did not affect the speed of the
traffic being surveyed.
After the data on actual speeds has been
analyzed, the speed limit is normally set at or below the speed at which
85 percent of drivers are driving. Speed limits cannot be set
arbitrarily low, as this would create many speed violators and would not command the respect of the public.
An
engineering and traffic survey is to be reviewed five years after it has
been completed. If, at the five year point, the City Engineer finds
that conditions have not changed, it does not need to be reviewed for
another two years. If, when the engineering and traffic survey is
reviewed seven years after it has been completed, it does not need to be
reviewed for another three years. A new engineering and traffic survey
must be completed at the ten year mark.

engineering and traffic surveys for all of the major streets in
Roseville. Follow the links to download the latest engineering and
traffic survey.
Speed limit misconceptions
When
traffic problems occur, concerned citizens frequently ask the city to
lower the speed limit. There are widely held misconceptions that speed
limit signs will slow the speed of traffic, reduce accidents, and
increase safety.
Most drivers drive at a speed that they consider being
comfortable, regardless of the posted speed limit.
Before and after studies have shown that there are no significant changes in vehicle
speeds following the posting of new or revised speed limits.
Furthermore, research has found no direct relationship between posted
speed limits and accident frequency.
