Proposals for a ten-pitch site next to the A4440 in St Peter's were rejected by Worcester City Council's planning committee on Thursday.
Councillor Patricia Agar said safety issues at the proposed site, next to a "busy" dual carriageway, would be "horrendous," adding she "wouldn't want a human being next to that road".
Councillor Richard Udall described concerns over anti-social behaviour as a "red herring," and accused the local authority of "clutching at straws" by rejecting the application.
But Elena Round, Green councillor for St Peter's Parish, said noise and pollution from the nearby A4440 was "horrific" adding she "could not live with herself" to approve a plan next to the road.
"We're not going to put houses there so why do we think it's okay for somebody in a caravan to go there?" she said.
