Peak bodies want to reduce the speed limit in Sydney CBD to 30km/h in a push for increased safety and to bring the city in line with other parts of the world.
Transport for NSW reduced the limit to 40km/h in the city more than five years ago, and the last remaining local roads were changed to reflect the new speed in July last year.
But the authority encourages a 30km/h limit in high pedestrian areas, such as CBD zones and small suburban shopping strips, to support the state government's aim for zero fatalities on the roads.
Advocates say lowering the limit even further makes sense, with the CBD attracting high foot and vehicle traffic.
"It's the position of Transport for NSW that we should move to 30km/h zones in areas of high pedestrian activity," Pedestrian Council of Australia
