Abstract:
The National Road Transport
Commission commissioned MUARC to prepare an evaluation report assessing
the national impacts (costs and benefits) of reducing urban speed
limits as part of a proposal to allow national reconsideration of
a 50 km/h default urban speed limit in the Australian Road Rules.
This paper reviews available
data from each of the separate Australian trials and proposals to
reduce speed limits below the national default of 60 km/h on local
urban roads. Based on these data, estimates of the national impacts
of lower speed limits on urban local roads have been developed in
terms of costs and benefits, road safety and community impacts of
lower local speed limits. Estimates of the national impacts of extending
lower speed limits to urban collector and arterial roads currently
controlled by the default urban speed limit are also presented.
The paper identifies and assesses options for the way in which lower
speed limits are implemented, based on the range of approaches taken
in the separate trials and proposals in individual jurisdictions.
