 What is the criteria used to select blocks that will receive speed humps?

Using a scoring system, a combination of the following criteria are used when selecting blocks:

  • Police records for all types of crashes on the block
  • Police records for cars hitting pedestrians and bikes
  • The density of children 18 and younger
  • Density of homes
  • Proximity to a park or a school that generates traffic
  • A residential street that runs parallel to a commercial street and can be used as a cut through
 How do you select where on the block the speed hump will be installed?

A speed hump is an engineering tool to control speeding on residential streets. The location of the hump on the block is selected by a traffic engineer to ensure the optimization of its effectiveness for the entire block.

 Why are some speed humps asphalt and some rubber?

Most of the speed humps the City of Detroit has installed are asphalt due to their low maintenance nature and longevity. There are circumstances in which we use rubber in cases of:

  • A concrete street
  • A fire route
  • A road in poor condition that will be resurfaced soon
 If I see a damaged speed hump, who should I report it to?
