The new design of detectable warning tiles makes them easier to use in all sorts of settings. They often replace the speed bump used to slow down traffic in busy areas. The tiles come with textured surfaces designed to jiggle the car as it rolls across them. Not only will they alert the driver to busy intersections or areas where they need to drive slower, but they also work to keep drivers awake when traveling long distances. The man made material used for creating the tiles is less expensive than the old method of creating bumps in the road. They can also be placed on crosswalks to alert drivers to pedestrians.
