Transverse Line Marking - Cudlee Creek

18 Jun 2015

The Department of Planning, Transport and Infrastructure (DPTI) is committed to reducing serious casualty crashes on South Australian roads under South Australia’s Road Safety Strategy 2020 – Towards Zero Together.

Cudlee Creek Road, at the Fox Creek Road junction, has a history of casualty crashes, as a result of vehicles turning right from Fox Creek Road into Cudlee Creek Road.

On a trial basis, with the objective of reducing the speed of westbound vehicles approaching the junction, DPTI will install white transverse line markings on the  carriageway. This aims to allow motorists on Cudlee Creek Road more time to react to any vehicle attempting to turn right from Fox Creek Road.

The transverse line markings will consist of a series of diagonal parallel painted lines extending from both sides of the travel lane for 1 metre towards the centre of the lane on a 60 degree angle. The lines will be painted on the Cudlee Creek Road westbound carriageway, commencing 150 metres before the Fox Creek Road junction and extending for 100 metres in length. Skid resistant paint will be used on these line markings.

The concept of transverse line markings originated in New Zealand, where research and trials on improving their effectiveness in reducing traffic speeds, is ongoing. This is the first trial in South Australia and it will be monitored to assess its effectiveness.
