Traffic Engineering > Speed Humps
Speed humps are raised "bumps" placed across residential streets. They are designed to calm traffic in residential areas and near parks and schools. The city of Las Vegas began constructing speed humps in 1995 in response to neighborhood speeding problems.
Which streets should have them?
Unless chronic speeding problems exist on your street, speed humps are not warranted. Traffic control, such as police enforcement, is usually a better alternative. Speed humps are used for streets where traditional methods of slowing traffic have not been effective. A residential street will qualify for the city’s speed hump program based on the following criteria:
- 800 vehicles a day as required.
- The two-lane street must be mainly residential or else have a park or school on the street.
- The speed limit must be 25 miles per hour.
- There may not be any regional transit bus routes on the street.
- The street cannot be a designated emergency response route.
How do I get them put on my street?
Any citizen or neighborhood association may request consideration for installation of speed humps by submitting a written petition with signatures from residents of at least 10 homes along that street. Refer to the Speed Hump Program document for more information and petition samples.
Requests should be mailed to:
City of Las Vegas
333 N. Rancho Drive
Las Vegas, NV 89106
When you submit your petition, be sure to include the name of the street on which you feel placement of speed humps would be appropriate and why. Include your daytime telephone number in your correspondence so that we can contact you.
Once the Traffic Engineering Division receives the request, a traffic count is taken. Crews set up equipment to measure how many cars use the road each day. One requirement for speed hump approval is that THERE MUST BE AT LEAST 800 VEHICLES A DAY TRAVELING THE STREET. Following the traffic study, Public Works staff will contact you with the results. Keeping pace with traffic activities in one of the fastest growing cities in the country poses challenges for Public Works staff. While it is our aim to provide you with the best service possible, there may be times when we may not respond to your requests as quickly as we’d like to. Please be patient. We will do our best to provide you with a response in as timely a manner as possible.
What are the drawbacks of speed humps?
Aside from the inconvenience of construction, some people prefer not to have speed humps placed near their driveways. Some worry that motorists will steer onto sidewalks or yards to avoid the humps. Others fear that those speeding over the humps will be noisy or the humps will devalue their homes.
Due to engineering studies that must be completed for each street, speed humps are expensive and only installed after approval by the City Council. Some neighborhoods which qualify for speed humps must wait a long time because limited funds are allocated each year for Neighborhood Traffic Management.
