The government body charged with road management in Victoria has reacted to public calls for a more consistent speed limit regime throughout the state.
But in outlining a simplified matrix of speed limit zones in Victoria, VicRoads has further reduced speeds on some sections of road, where it has been deemed there is a higher density of pedestrian traffic or more residential premises.
It's not all bad news, however, with the traffic authority recommending in its report — The Victorian Speed Limit Review — that municipalities apply a time-based 40km/h limit where currently school zones are subject to permanent (24-hour a day) 40km/h limits.
Also among the outcomes covered by the report is one that will see speed limits from 'collector roads' increase to 60km/h. In addition, road signage will be improved with less clutter and 80km/h buffer zones, between the 100km/h and 60km/h zones entering towns, will be no more. Instead, the 80km/h zone signage will be replaced by new signs reading '60 ahead' (pictured).
Of the 12 outcomes in the report, in response to 614 submissions received from the general public between August and October, 2011, two specifically relate to ending 70km/h and 90km/h zones in the state. 70km/h zones will become, according to need, an extension of an adjacent 60km/h or 80km/h zone. Similarly, 90km/h zones will be integrated with 80km/h or 100km/h zones.
The 12 outcomes are as listed below:
Change speed zones at locations identified by the community
Remove 80km/h buffer zones
Review 90km/h limit
Review 70km/h limit
Reduce sign clutter
Remove 'End Limit' signs
Guidelines for 40km/h pedestrian zones
Increase speed limit on collector roads to 60km/h
VicRoads to launch a public awareness campaign to illustrate how speed limits are set
Increase awareness and encourage uptake of Intelligent Speed Assist (ISA) devices
Raise awareness of need for lower speed limits
The report also identified issues that were "outside the scope" of the review. These included roadworks speed limit zones, increased speed limits on freeways and speed camera tolerances. VicRoads advises drivers who have a complaint concerning a roadworks site that doesn't appear to be manned, but where a lower speed limit is enforced, to contact the department's Customer Service team on 13 11 71.
In response to the question posed by some respondents — 'why can't we have higher speed limits on our freeways, like the German autobahn?' — VicRoads claims that any benefit would be marginal and more than offset by increased fuel use, environmental concerns and the likelihood of crashes.
Raising the speed limit from 110km/h on a rural freeway to 120km/h would reduce the travel time on a 200km journey by just nine minutes, according to the report.
As for speed camera tolerances, the report explains that since July 2006 cars sold in Australia must comply with a specific ADR (Australian Design Rule) that stipulates an indicated speed must never be lower than the car's actual speed.
The report revealed that VicRoads will begin implementing the new speed limit framework from this financial year (2012/13), but the authority expects a number of the recommendations will take longer to complete. Speed limit changes have been officially published at a VicRoads web page for scrutiny by the public.
