Speeding on residential streets
is a common complaint reported by citizens, but police officers
cannot always be present to cite speeders.
The Los Angeles Department of Transportation (LADOT) is often requested
to influence driving speeds. Although the measures LADOT puts
in place may not be as effective as police enforcement of
they can have some impact. Residents with concerns about excessive speeding may request the appropriate
LADOT District Office to investigate the speeding concern. See the Contact Us
Section for the District Office information.
signs are sometimes viewed as a cure-all for solving residential
speeding problems. But four-way stop sign controls should
be used only where high safety risks exist or high-to-moderate
traffic comes from each direction.
The Los Angeles Department of Transportation has pioneered
the concept of a two-way stop pattern as a more appropriate
alternative to four-way stops. This pattern places two-way
stop signs at every other intersection in a residential
two-way stop pattern:
- Manages excessive speeds
- Provides needed right-of-way control
- Avoids creating routes attractive to commuters
The City's Citywide Speed Hump Program has been DISCONTINUED, since the program budget was cut in
Fiscal Year 2009-2010. Therefore, LADOT CAN NO LONGER ACCEPT REQUESTS for new speed hump installation or new engineering feasibility studies.
For further information concerning the termination of the Speed Hump Program, please see the
Frequently Asked Questions. We appreciate your understanding during these difficult times.
When resurfacing occurs on streets with existing speed humps, the Department of Public Works, Bureau of
Street Services (BSS) will re-install the speed humps at the same location at a later time after resurfacing, using specialized equipment and crews. For more information,
please contact BSS at 311 or (800) 996-2489.
Existing speed humps were installed to reduce speeds on residential streets. An engineering feasibility
study based on multiple qualification criteria, and a petition process were conducted before they were approved and installed. The goal
of speed hump installation was to lower the speed at which 85 percent of the drivers are driving, down to within five miles per hour above the speed limit.
The City of Los Angeles installed two types of Speed Humps. Type 1 speed humps are 2-5/8 inches to 3 inches in height, and
12 feet in length. Type 2 speed humps are 2-5/8 inches to 3 inches in height, 22 feet in length. The determination of feasbility
of installing a Type 1, Type 2, or none at all, was based on multiple engineering criteria, including but not limited to traffic volume and roadway slope.
