I don't like a particular type of traffic calming device. Why has the City chosen it?

Not all traffic calming devices are effective or suitable in every situation. The City makes a decision on the best option after considering all of the factors relevant to the particular road.

How does the City make a decision on traffic management proposals?

The City seeks feedback from the owners and occupiers of properties on the section of road that is proposed to be upgraded by sending a notification letter, which contains a validating code.

If the proposal receives more than 50 per cent support, based on the feedback received, the proposal will be approved. The typical response rate for this type of project is between 10 per cent and 30 per cent. The City considers that those who choose not to respond have no preference about the proposal and are equally satisfied whether it goes ahead or not.

All submissions from residents and owners of affected properties that contain a valid Unique ID are given equal consideration. 

What happens if I don’t provide feedback?

The City considers all non-responses as having no objection to either the installation, or non-installation of the proposed works.

What is the timeframe for completion of the upgrade?

Design and public consultation is usually undertaken approximately 12–24 months prior to the on-site construction works.

How does the City determine whether a road should have traffic calming?

A road that has been reported as having a traffic or road safety issue is assessed under the City’s Traffic Management Warrants Policy. The traffic speed and volume data used in the assessment is obtained from traffic surveys conducted by the City. The crash data is sourced from a database of all crashes reported to the Police in WA. 

How does the City select the type of traffic calming treatments used?

The City carries out an extensive assessment of all local road characteristics and constraints to determine the most suitable traffic calming devices to be used. A concept proposal is prepared based on this assessment. 

Some of the factors considered during the selection process include: volume and type of traffic, drainage, vegetation and existing driveways. 

There are many different types of traffic calming features, such as vertical displacement devices like speed humps and speed cushions and horizontal displacement devices like chicanes and roundabouts. The effectiveness and suitability of each are assessed according to the individual situation.

The City will always propose the option determined to be the best solution for the particular road.

Why doesn’t the City install traffic signs or use speed cameras?

The installation and management of all regulatory traffic signs in WA, such as speed limit, Stop and Slow Down, is solely under the jurisdiction of Main Roads WA (MRWA). MRWA has strict criteria in place for the installation of these traffic signs. The City will only consider regulatory traffic signs as an option, and apply to MRWA for their installation, if the road is assessed as meeting these criteria.   

Speed cameras can only be used by WA Police. 

Given the limited resources of WA Police and the vast local road network, enforcement action is focused on local roads with an 85th percentile speed of 10km/h or greater over the speed limit. 

The City reports these instances to the Police however, Police presence is not a permanent solution for traffic safety issues.

How does the City know that this treatment will improve the safety on our road?

The City has extensive experience in constructing traffic safety projects on its road network. After each project, the City conducts post-implementation traffic surveys to determine the effect of the works on traffic conditions.This experience indicates that the traffic treatments used by the City typically improve safety by reducing the prevailing speeds of the traffic. 

Will I still be able to enter and exit my driveway?

Upgrades are designed to retain the same level of access into existing driveways.

I agree with the need for traffic calming but I do not want a treatment in front of my house.

With any type of treatment, the City recognises that some residents may feel more impacted than others. Once a road has been identified as warranting traffic calming, the City has an obligation to address this problem for the benefit of the broader community.

The final decision on traffic calming proposals will be made based on the feedback from all residents and owners of properties impacted by the works, and who have received a notification letter with a validating code.

How will we be informed about the outcome of the consultation?

The outcome of the consultation will be communicated to the owners and residents that received the original letter and made a submission.

What will happen if my verge or driveway is damaged or if it has to be modified as part of this plan?

All driveways affected by the proposed works will be reinstated according to the City’s standards. Any irrigation affected in the verge area will be adjusted and reinstated to property owner’s requirements.
