Speed Management
Learn about speed display boards and how they are used to slow traffic.
To manage speeding on our streets, The City of Markham uses speed display boards to improve driver behaviour.
You’ll see speed display boards all over Markham. These devices use radar technology to detect vehicle speeds and display it back to the driver. They let drivers know if they are driving too quickly and need to slow down. Studies show that vehicle speeds are reduced by up to 20 percent when these signs are placed.
