The growth in traffic volumes on Melbourne’s freeways means more of a focus must turn toward better managing existing infrastructure, Victoria’s top transport bureaucrat says.

Speaking at the Speaking at the 8th Annual Australian Roads Summit in Melbourne recently, VicRoads CEO Gary Liddle told attendees a smarter approach is needed to cope with the predicted doubling of the freight task by 2030.

He says volumes on Melbourne’s freeways are growing 2 percent each year.

Liddle says the introduction of ramp signals on the M1 in 2007 has helped reduce congestion and increase travel speeds by 25 percent during the morning peak and 59 percent in the afternoon.

It has also reduced casualty crashes by 30 percent, he adds.

"On AM peak the speed was 50km/h, the average speed is 85km/h now," Liddle says.

"It has made a big difference to how people get to and from work every day.

"We have over 3000 sets of traffic signals around Melbourne. It’s amazing how much efficiency you can gain by optimising those signal sets.

"This performance means that road users, including freight accessing this important corridor, are provided with a transport facility that lowers their travel time and operating costs for most of the day, reversing the trend of lengthening and congested peak periods."
