Solutions to Sydney's worst traffic congestion hot spots will be "crowdsourced" by the NSW government to tap into the widest possible pool of ideas.

The Premier's Innovation Initiative will be launched on Thursday and from next month seek submissions on how to reduce traffic in the worst of the city's choke points.

"We need to think more innovatively about how our existing metropolitan-wide infrastructure could work more efficiently," a fact sheet says.

"Private and community sectors can provide innovative solutions to reduce congestion on hot spots on Sydney's roads."

International examples such as an "automated roadwork zone information system" in Los Angeles, which diverts traffic to alternative routes, and Toronto's "corridor retiming program", which retimes traffic signals to improve traffic flow, are highlighted.

The government is reluctant to specify which Sydney hot spots it is targeting for fear of restricting ideas that might be brought forward.

But the initiative is likely to complement its existing Pinch Points program which looks at ways to relieve peak-hour traffic congestion.

The initiative will also invite proposals in other areas.

Submissions will be sought on how best to finance "replenishment" of public housing and fast-track release of "open data" government information to improve service delivery.

More broadly, it will ask the public to nominate areas where a "policy challenge" exists and suggest solutions.

Premier Mike Baird said the initiative would use a "competitive selection process to identify inventive solutions from private and non-government organisations".

“One of the best assets the state of NSW has is its people and we know that government doesn’t always have the answers,” he said.

“This exciting initiative is about opening up government avenues to the public and combining our considerable know-how.”

Mr Baird said such an initiative had worked in the UK with the London Ventures program.

Among the solutions being developed under London Ventures - run by the organisation representing London councils - is a model that uses data to predict the likelihood of children under two being neglected or abused by the age of five.

The hope is that it will eventually lead to less intervention in families as well as cutting costs.

Another, "Pitchwise", is a website that allows residents to search for and book football grounds.
