Cars speeding down streets in residential areas and business districts could be potential headaches for residents, business owners, and pedestrians. This is where traffic calming devices such as speed humps could be quite useful. And this is especially true for business owners. It’s important, after all, that you ensure the safety of your customers.
But how exactly do speed humps help? Well, it’s because these traffic calming devices urge drivers to slow down. If they don’t, drivers will not only experience extreme discomfort, but also possibly damage their vehicles.
However, there are different kinds of speed humps out there and not all road types are allowed to have them. So which one should you have installed in your street or property?
WHAT ARE THE DIFFERENT TYPES OF SPEED HUMPS?
Speed humps can be of different types, material, and measurement. But two of the most common types are the ones below:
Trapezoidal speed humps → these are flat top speed humps that would best suit local streets or main roads in small communities. This can be installed with a wider top that could double as a pedestrian lane or crosswalk. Due to this, most installations of trapezoidal speed humps increase the visibility of crosswalks, as well as the possibility of drivers giving way to pedestrians.
Semi-circular speed humps → these are speed humps with rounded tops, and because of the sloped surface, they’re not quite safe for pedestrians to use. More importantly, in the Australian Standards through AS2890.1:2004, it is stated that all speed humps should have flat tops, not rounded ones.
If you’re planning to install speed humps mainly in a parking area, then you should get the ones that comply with the Australian Standard for Type 2 Speed Hump, which has the following four main specifications:
- Each one should have a height of 25mm to 75mm.
- Each must be flat on top or trapezoidal, not rounded or semi-circular.
- Each must have a ramp angle of 2:1.
- Each must have alternating parallel stripe markings of 250mm wide, which could be yellow or white in colour.
Now, how do you choose exactly which ones to have installed? Well, below are some questions you might want to answer first before making your choice.
WHAT TYPE OF ROAD DO YOU HAVE?
Most cities classify their roads according to its location and the amount of traffic it gets. In Brisbane, roads are classified into six categories:
- Arterial Route
- Suburban Route
- District Access
- Neighbourhood Access
- Local Access
Of the six road types, however, installation of speed humps can only be possible with Neighbourhood and Local Access road types. The first four road types get high vehicular traffic, around 3,000 to 30,000 vehicles per day. Due to this, the city council has deemed it unsuitable for traffic calming devices such as speed humps.

WHAT IS THE AVERAGE VEHICLE TRAFFIC ON YOUR STREET?
As have been mentioned above, local city councils do not recommend installing speed humps in roads or streets that get a lot of traffic every day. After all, speed humps are mainly for the benefit of pedestrians and cyclists… since they are the most vulnerable road users of city streets. If your street falls under the two classifications, which are Neighbourhood Access and Local Access, that can have speed humps, you may then ask your local city council to assess your neighbourhood street. Often, they would do this by collecting valuable data such as average traffic volume and speed in your street using tube counters that will be temporarily installed on the surface of roads.
WHAT IS THE SPEED LIMIT ON YOUR STREET?
The average speed limit set for vehicles in the city of Brisbane is 50km per hour. Unless otherwise stated in road signs, this is true for all roads within the city. And this is also true for Neighbourhood and Local Access road types. In cases when roads have a different set speed limit, however, visible signs at regular intervals will be posted along the streets or roads so motorists would be aware of them. In school zones, for instance, the speed limit is usually 40km per hour. And it’s expected that there will be signs around and on the roads themselves indicating them as such.
Now, if you think that the roads or streets within your residential community should have a lower speed limit, you may have your roads assessed by your local city council. You can also ask them for advice on how to go about requesting permission on installing speed humps, which would force stricter compliance for drivers using your street, especially in the event that your city council agrees to lower its speed limit.
WHAT DO THE EXPERTS TELL YOU?
After all other considerations and criteria, you still should consult the professionals about it. People with knowledge of traffic engineering are the ones who have had years of experience, as well as the technical know-how, to correctly determine which speed hump design and material would best suit your needs. Just make sure that you find someone you can trust to do the work right. Ask for references or seek out customer reviews, so you have some idea on their quality of work and expected output.
Speed humps are ideal for limiting vehicle speed not only in local neighbourhood streets, but also carparks and shopping centre driveways. But just to be sure, consult your city council before having them installed, so you don’t end up paying a fine and having them removed anyway.
