Five city centre streets are likely to be closed to traffic on European Car Free Day, Saturday September 22.
Brighton and Hove councillor Chris Morley is being asked to approve the closures at a private meeting on Wednesday.
Environmental groups criticised the city council for not taking part in the day last September. It was widely observed in continental Europe and some UK cities.
The idea is to encourage people to use transport other than the car and rediscover parts of their area.
Environment director Alan McCarthy is recommending the closure of Prince Albert Street, Bartholomews, Little East Street, East Street and a small section of King's Road behind the Queen's Hotel.
Arrangements will be made for deliveries to shops and emergency services access.
Mr McCarthy said: "The main thrust of the day could be further enforced by a more vigilant approach to existing traffic regulation, particularly in North Street and Western Road."
