Possibilities include marked cycle lanes, adjustments to intersections and provision of "in-lane" bus stops.
Council staff will review the submissions before determining the next steps.
The corridor under consideration runs north along George St from the Albany St intersection and into Bank St up to North Rd.
"It’s a busy road which includes bus stops, shops and schools, as well as being a thoroughfare to the north of the city, and a key residential area for tertiary students," the council said in its consultation material.
"We’re proposing infrastructure improvements to ensure it’s safer and easier for everyone to use regardless of their mode of transport."
Cycle lanes could be marked out between Albany St and North Rd.
It is proposed a temporary roundabout at the intersection of George, St David and Park Sts and Regent Rd be made permanent, but it has yet to be determined how the intersection would function.
There could be left-turn bans from George St into Park St and from Park St into Regent Rd, and no access into the roundabout from St David St.
The block of St David St between George and Great King Sts could be turned into a one-way street.
In-lane bus stops allow buses to stop without having to then merge with traffic to continue their journey.
However, they can also result in traffic having to wait behind stopped buses.
Waka Kotahi NZ Transport Agency would fund 90% of the work through its transport choices programme and the rest would come from the council’s Shaping Future Dunedin Transport budget.
In separate consultation about Dunedin traffic speed management, it is proposed the corridor would have a 30kmh limit.
