In south-east Queensland, motorways are the preferred route for many drivers. As the number of motorway users continues to increase, so does the risk of congestion along popular routes, which can result in slow-moving, stop-start driving conditions.
To reduce the onset and duration of congestion, centrally-controlled electronic signs and signals are used to help keep traffic flowing onto and along motorways.
These technologies are collectively referred to as 'Intelligent Transport Systems' and include variable speed limit signs, flexible lane controls, electronic message signs and traffic-lights at motorway on-ramps.
Similar systems have been successfully used overseas, including in the USA, UK and New Zealand, and are now being introduced into Australia.
Traffic Management Centres in south-east Queensland will monitor traffic and weather conditions via closed circuit television (CCTV), weather monitors and other traffic data collection devices (such as vehicle detector loops).
Central collection and analysis of real-time data will allow for quick decisions, and the immediate broadcast of instructions to motorway drivers, such as changing speed, changing lanes or watching out for an accident ahead. This in turn manages congestion and keeps traffic flowing.
It is important that drivers understand how to respond to changing motorway signs and instructions. Compliance will maximise the benefits to all motorway users.
