The Government is aiming to reduce road deaths by 40 percent over the next 10 years by upping its spending on transport infrastructure.
But the money won't come from road user charges or new petrol taxes if Labour is re-elected.
Transport Minister Phil Twyford on Thursday released the final Government Policy Statement on land transport (GPS) 2021.
It outlines $48 billion of "investment in services and infrastructure over the next decade", including an immediate $510 million boost to state highway maintenance funding and $500 million for rail.
"Safety remains our Government's top priority and we're aiming to reduce the number of deaths and serious injuries on the road by 40 percent by investing $10 billion in our Road to Zero strategy," said Twyford.
"That means on average $1 billion a year being spent on better resourcing the police on our roads, safety infrastructure like median barriers, and public safety campaigns."
Twyford says the present Government inherited run-down state highways, and the new investment will create thousands of jobs.
"This extra half-a-billion dollars will make a significant difference and help us play catch-up, and get the state highways back into better shape."
Twyford also said if re-elected, Labour would not raise petrol taxes and road user charges during their next term.
"The more we can move people in our cities and freight around the country on the rail network, that's a fantastic way to reduce greenhouse gas emissions."
The GPS, developed by the Ministry of Transport for the minister, is reviewed every three years. It sets out the Government's spending priorities for the National Land Transport Fund. Its four 'strategic priorities' this year are safety, better travel options, climate change and improving freight connections.
