Understanding Speed Hump Standards


At Area Safe, we often get asked by our customers, "What standards do I need to follow when it comes to speed humps?" This is a great question because ensuring compliance with standards is crucial for safety, legal adherence, and the longevity of your car park infrastructure.

In Australia, the primary standard you need to follow for speed humps is the Australian Standard AS 2890.1:2004, which outlines the requirements for off-street parking. This standard ensures that speed humps are designed, installed, and maintained in a way that enhances safety and complies with legal regulations.

Understanding AS 2890.1:2004

To help you understand what this standard entails, let's dive deeper into its key components:

Purpose of Speed Humps

Speed humps are critical for reducing vehicle speeds in areas with high pedestrian traffic, such as car parks, shopping centres, hospitals, and residential areas. They help prevent accidents and improve the safety of drivers, cyclists, and pedestrians.

Types of Speed Humps

According to AS 2890.1:2004, there are two primary types of speed humps used in car parks:

  • Type 1 Speed Humps:
    • Intended for long aisles and circulating roadways in large outdoor car parks.
    • Designed to reduce vehicle speeds to about 25 km/h or less.
    • Specifications: Maximum height of 75mm and a total width of 2500mm.
  • Type 2 Speed Humps:
    • Used in confined areas of covered and multi-storey car parks.
    • Aim to reduce speeds to about 30 km/h or less.
    • Specifications: Height ranges from 25 to 75mm, with a 1:2 ramp angle. The raised flat-top section is 100 to 150mm wide, with additional width on either side for the road level.

At Area Safe, Type 2 speed humps are the typical solution we provide to customers due to their versatility and effectiveness in various parking environments.

Design and Marking Requirements

  • Markings: Speed humps must have alternating parallel white or yellow stripes, each 250mm wide, to enhance visibility.
  • Installation: Speed humps should be installed clear of intersections and curved roadways to avoid impeding pedestrian or wheelchair traffic. At least 1m of travel space is required on either side of the hump when placed near accessible paths for people with disabilities.

Spacing Guidelines

  • Type 1 Speed Humps: Should be spaced a minimum of 30m apart along a single aisle or roadway.
  • Type 2 Speed Humps: Should be spaced at least 10m apart, with a maximum spacing of 50m for continuous speed control.

Additional Safety Measures

To ensure maximum safety, especially in low-light conditions:

  • Reflective Pavement Markers: Raised reflective pavement markers may be required in addition to hump stripe markings.
  • Warning Signs: A W5-10 hump warning sign should be used if the speed hump is not sufficiently visible for drivers to slow down in time.

Maintenance and Compliance

Regular maintenance is crucial for the longevity and effectiveness of speed humps. This includes:

  • Prompt Repairs: Organizing repairs or replacements as soon as any damage is detected to ensure ongoing compliance and effectiveness.
  • Routine Cleaning: Removing debris like leaves, dirt, or litter to maintain visibility and functionality.
  • Scheduled Inspections: Checking for signs of damage or wear and tear, such as cracks or loose fittings.

Why Compliance Matters

Adhering to AS 2890.1:2004 not only ensures the safety of all car park users but also provides long-term cost benefits by reducing the need for frequent repairs and minimising the risk of legal issues due to non-compliance.

Following the Australian Standard AS 2890.1:2004 for speed humps is essential for creating safe and compliant parking facilities. By adhering to these guidelines, you ensure the safety of drivers and pedestrians while also enhancing the efficiency and longevity of your car park infrastructure.
