The NSW Roads and Traffic Authority (RTA) has confirmed that it will release the final results of a recently concluded trial into the implementation of advisory intelligent speed adaptation (ISA) technology by the year's end.
The trial of the technology, which alerts drivers when they have exceeded the legal speed limit, was conducted by the RTA’S NSW Centre for Road Safety and is claimed to be the largest test in Australia to date.
Concluding at the end of April it saw more than 110 vehicles taking part and over 7.5 million speed location records collected throughout the trial.
An RTA spokesperson told Computerworld Australia that the trial's aim was to research the road benefits of the system, measure the economic benefits in terms of fuel consumption and effects on journey time, and assess the value of ISA systems for private drivers as well as fleet managers.
The news follows a recent roundtable hosted by Victorian Roads Minister, Tim Pallis, which discussed the use of ISA technology as a means to save lives in the state.
Organisations that attended included the Transport Accident Commission, Royal Automobile Club of Victoria and Bicycle Victoria who discussed the possibility of implementing the ISA technology.
A VicRoads spokesperson confirmed the technology was already under trial in the state, and sees ISA devices installed in the vehicles of drivers with a record of receiving demerit points for speeding offences.
The VicRoads ISA devices use visual and audible cues to alert drivers that they are speeding. A data logger, also affixed to participants’ vehicles, tracks changes in driving behaviour such as whether or not they slowed down when the device issued the alert.
"The results of the trial will assess the changes in speeding behaviour of the drivers who had an ISA device installed, and those who didn’t," the spokesperson said. "While the ISA device will be removed after three months, the data-logger will continue to monitor the driver’s speeding behaviour for a further two months to help monitor any reduction in speeding without the ISA alerts."
ISA technology comes in three forms -- ‘Advisory’ alerts the driver when they have exceeded the speed limit (using an audible alarm or message), ‘Supportive’ restricts the flow of fuel to the vehicle’s engine when the driver exceeds the legal speed limit and the accelerator becomes harder to push. ‘Limiting’ actually restricts the vehicle’s speed to the legal speed limit.
A device is fitted to the car and mounted on the dashboard and then alerts the driver to the speed limit of the road they are currently travelling on, via bearings from satellites.
Early results from the NSW RTA’s trial released in November last year, show that the ISA device almost halved the amount of time drivers spent travelling more than 5km/h above the speed limit.
