Roads—traffic lights (Question No 1571)
Ms Le Couteur asked the Minister for Territory and Municipal Services, upon notice, on 17 February 2011 (redirected to the Minister for Transport):
(1) How does the Department of Territory and Municipal Services decide whether roundabouts, traffic lights, or other measures, are appropriate for a road intersection.
(2) What is the approximate cost of installing traffic lights at an intersection, compared to roundabouts.
(3) What consideration has the Government given to using hybrid roundabouts, which are roundabouts that utilise traffic lights during peak hours, for intersections in Canberra.
Mr Stanhope: The answer to the member's question is as follows:
(1) The decision to adopt either traffic lights or a roundabout at a road intersection is based on a consideration of the specific location; the various road user requirements and forecast traffic volumes, the location of services and the need to provide priority for buses, cyclists and pedestrians.
(2) The cost of installing traffic lights depends on the type of intersection (eg. three way, four way, at grade, interchange etc) and the complexity of the associated work involved (eg. amount of road infrastructure work required to retrofit and/or construct). Recent work undertaken in the ACT suggests that an average cost for constructing a set of traffic lights commences at about $0.60 million. Roundabouts typically cost in the range of $0.5 million - $1.5 million depending on the nature of the specific location and the lane configuration adopted.
(3) The ACT Government has considered the use of hybrid roundabouts. The ACT currently has two roundabouts which use traffic lights to generate gaps during the peak periods. These include the roundabout at the intersection of Isabella Drive and Athllon Drive and the roundabout at Brindabella Circuit and Pialligo Avenue at the Canberra Airport.
I also understand that an assessment of adopting this approach on the large roundabout on the Barton Highway / William Slim Drive is currently underway.
