Labor is promising to encourage more people to bike and walk by boosting spending on cycleways and pedestrian links to $412 million over the next four years if it wins the state election next month.

Vowing to "reinvigorate active transport", Labor's transport spokeswoman, Jodi McKay, said it would invest the money, if elected, into cycling and pedestrian infrastructure, as well as rail trails in regional NSW, in its first term of government.

"It is about trying to get people back on their bikes," she said.

"Supporting cycling and pedestrian infrastructure means less cars on the road, reduced emissions and air pollution, and has a proven impact on public health and wellbeing."
