How Traffic Calming Helps Road Safety

Australian road engineers use a number of traffic calming measures to slow down or reduce traffic to improve safety. Some of the most common physical means include roundabouts, chicanes, speed humps, rumble bars and lane dividers.

Over the last 10 years, there has been a 24% increase in the number of vehicles registered in Australia. With so many more vehicles on the road it might be surprising to learn that road fatalities have dropped by 60% in the last 30 years. Part of this equation has been the development and implementation of traffic calming devices on our roads.

What Is A Traffic Calming Project?

A traffic calming project is usually designed to reduce and minimise the risks posed by vehicles, particularly in built up areas. It involves implementing design features and strategies to reduce traffic speed and volume and provide more space for pedestrians and cyclists. A traffic calming project can be something as simple as minor modifications on a specific street to a more comprehensive engineering redesign of a road network.

How Can Road Safety Be Improved?

According to the Centre For Accident Research and Road Safety, there are a number of engineering interventions that have proven effective in improving pedestrian safety. These include:

  • speed management measures at intersections and high volume pedestrian areas such as school zones
  • better footpaths and preventing / diverting vehicles from pedestrian areas
  • improving motorist, cyclist and pedestrian awareness and behaviours.

 

What Are The Most Common Traffic Calming Devices Used?

Australian road engineers use a number of traffic calming measures to slow down or reduce traffic to improve the safety of all motorists, pedestrians and cyclists. Some of the most common physical means include roundabouts, chicanes, speed humps, rumble bars and lane dividers.

The following measures are designed to slow cars to anywhere between 10 and 40 km/h. In the past traffic calming devices were traditionally constructed from asphalt or concrete but today many products are made of rubber for a safer, more modern alternative.

Speed Humps: Small and effective speed reducers, usually used for very low-speed areas like carparks. They are rounded and spans the width of the road, used on residential streets.

Speed Cushions: Two or three speed humps placed in a line across the road.

Speed Tables: A wide speed hump with a flat top, typically used in residential areas and for pedestrian crossings.

Chicanes: Requires drivers to negotiate road build outs in residential streets and give way to opposing traffic.

Rumble Bars: Alerts drivers to approaching intersections, crossing shoulder, centreline and lane departure areas.

Lane Dividers: Help to delineate lanes and roundabouts.

Bollards: Used to identify hazards and separate pedestrians from traffic movement.

Another effective means of traffic calming is road narrowing which enforces a natural reduction in speed. Visual cues, such as roadside planter boxes, bike lanes and on-street parking, signal drivers to slow down and pay more attention, thereby reducing the likelihood of crashing and causing injury to other motorists, cyclists and pedestrians. Often roading engineers add a brick coloured overlay to roads as a visual indication of high traffic areas. A vehicle activated sign with a ‘slow down’ appearing is a common visual way to get the message across.

The narrowing of roads can be achieved by several methods, including extending the footpath, curb extensions and chokers, which narrow the road to a single lane at vital safety points like pedestrian crossings. Removing a lane from a busy road, known as ‘road dieting’, also reduces traffic speed, as do pedestrian islands in the middle of the road and adding parking on one or both sides of the road.

Some high-risk areas where traffic calming measures are essential are residential areas, schools, hospitals and well-known crash spots. When creating traffic calming plans, roading engineers don’t just think about the physical measures or visual cues they need to put in place. Public education on driver behaviour and police enforcement are also necessary components for successful traffic calming.
