Measuring traffic
The City of Port Phillip has a core responsibility for the management of the local and much of the arterial road networks within its boundaries.
To understand the impact of the road networks on our community, the council measures traffic flow and growth and the types of vehicles using our roads. The data collected about how the road networks are performing provide an indication of where resources for traffic management should be directed.
Data is collected on 52 key local and arterial roads annually. Data is also collected on other significant roads as required, and in response to specific community concern. Data is not available for all streets as there has not been a need to collect this information in the past.
See  Updated Traffic Speed & Volume Nov 2008 for details.
If you feel there are adverse traffic volumes, speeds or vehicle type (ie large vehicles) in your street and data is not available for you to consider, please contact the council. Use eServices to ask us a question, request information or give us feedback online. If you prefer call ASSIST on (03) 9209 6777 or TTy (03) 9209 6713 and ask for Traffic Transport & Parking.

Managing traffic
The City of Port Phillip does not have a formally adopted traffic management policy which provides an automatic response to adverse traffic volume / speed / vehicle type concerns. The council's traffic engineers will, however, consider the following industry-accepted guidelines to determine if further investigation of traffic conditions in a particular street or area is required.
|
Local Street |
Fawn |
500 - 3,000 vpd^ |
<12 - 14% of daily volume |
<63km/h# |
|
Collector Road |
Orange |
3,000 - 8,000 vpd |
<12 - 14% of daily volume |
<63km/h# |
|
Arterial Road |
Red / Black |
> 10,000 vpd |
N/a |
<106% of speed limit |
vpd - vehicles per day
^ It is noted that some local streets operate satisfactory towards the higher limit while others are in the order of 500 vpd, see below factors for further explanation.
* Is the speed at which 85% of traffic travel at or below. Is often the indicator that determines the actual speed limit.
# Speed limits in all local streets and collector roads within the City of Port Phillip were lowered to 50km/h in Dec 2000. At this time, any physical traffic management response in 50km/h streets would be assessed as if they were still 60km/h. The cultural change to slow motorists to levels at or below 50km/h is continuing and expected to take a number of years. Note, this only applies to physical responses and not police enforcement or other initiatives identified.
Hint: Check the Melway street directory for the functional classification of your street.
If traffic conditions for a particular street fall outside the limits outlined in the above table, further investigation may be conducted to consider:
- Road function and classification
- Road network connectivity
- Surrounding land use
- Accident history
- Types of road users (pedestrians, cyclists, special needs, public transport)
- Road geometry and design
- Impact on adjacent road networks
- General environment
Following a review of these factors and the development of an appropriate traffic management response, community comment would then be invited on any traffic management plans recommended.
