Raised pavement markers

Purpose

• Used to increase visibility and improve awareness of adjacent road line markings, traffic devices and road side items
• Provide day and night visibility during adverse weather conditions
• Provide noise and audible warning for vehicles when crossed
• Improve road safety by providing directional cues for motorists along path of travel

Different types of Raised Pavement Markers

Road humps

Purpose

• Reduce vehicle speeds by causing discomfort when vehicles are driving in excess of the design speed of the hump

Traffic islands

Purpose

• Channelization of vehicles and reduce speeds  by narrowing the width of the road

Chicanes/Slow Points

Purpose

• Slow points are mid-block traffic islands that narrow the roadway to break-up the continuity of the street to reduce vehicle speeds

Roundabouts

Purpose

• Roundabouts reduce vehicle speeds, conflicts and simplifies the allocation of priorities for vehicle movement.

Pedestrian crossings

Purpose

• A device that enables a point where pedestrians can cross the road and have priority over vehicles on the roadway. A pedestrian crossing imposes a legal requirement on vehicular traffic to give way to pedestrians and improves safety for pedestrians

Pedestrian refuge islands

Purpose

• Refuge islands are used where there is a need to provide a place of safety for a concentration of pedestrians in circumstances where it is difficult to cross the full width of a roadway in one stage.

Traffic Lights

Purpose

• To facilitate the safe and efficient movement of vehicles on roads that have high traffic flow and to prevent conflict between the movements
• To facilitate pedestrian movements on roads that have high traffic flow

Light Thoroughfare Roads

Purpose

• To improve local amenity of the street by restricting heavy vehicle access
• To prevent the use of trucks using streets as short-cut routes to main roads
• To prevent damage to and ensure good condition of the road
