Westdene Primary School in Barn Rise
The scheme is also intended to improve safety outside schools and encourage active forms of travel, such as walking, cycling and scooting.
Nine schools took part in the trial and there are currently four schools running the scheme in Brighton and Hove.
Westdene Primary would join Brunswick Primary, St Luke’s Primary, Downs Infant, Downs Junior, St Nicolas CE Primary in closing the road outside school gates.
The school is closing Barn Rise for the full day so pupils can take part in activities on bike safety, air pollution and active travel, the council said.
