What are those raised sections of road at some intersections?

You may have noticed raised and coloured sections of road at some intersections with traffic lights.

Known as Raised Safety Platforms (RSPs), they are designed to slow vehicles approaching and travelling through the intersection, which helps decrease both the likelihood and severity of a crash. Slowing vehicles at intersections also improves safety for people walking, cycling, or using eRideables.

The markings on the platform ramps highlight the presence of the raised area and the intersection ahead, to alert drivers to slow down as they approach, which, at traffic lights, can also discourage drivers going through an amber light.

RSPs are often used at intersections with no traffic lights in residential areas as well, for the same purpose.
