There are concerns the Sunday shutdown of one of Cardiff’s Park and Rides could increase congestion and air pollution.
The East Cardiff Park and Ride Sunday service at Pentwyn was axed by Cardiff Bus at the start of January.
Cardiff Bus said not enough people were using the facility.
But there are fears the change will encourage more people to drive into the city centre.
Steve Andrews, a regular user of the Park and Ride service said “It’s ironic that Cardiff Bus are one of the biggest complainants of congestion within the city yet are now contributing to it by the fact they’ve made this awful decision.”
Lib Dem councillor for Pentwyn, Joseph Carter, said: “For anyone driving in from the East of the city, from Newport to as far as Bristol, this is the ideal place to park.”
From February, the Park and Ride site will be used by Young Driver, a driving school for Under-17s.
Cllr Carter said this was a strange decision, claiming more needed to be done to find ways to get people out of their cars to deal with air pollution and congestion.
But Mike Pitt, a member of Friends of the Earth Cardiff, said that use of Park and Rides did not in fact help with air pollution as people still had to drive to the car park.
He said there needed to be a move away from cars altogether and towards other forms of public transport.
In a statement, Gareth Stevens, Commerical Manager at Cardiff Bus, said: “Since operating the service we opted to run the additional Sunday days at our own commerical risk i.e. the only revenue we gain for this would be from the fares taken on the day. Unfortunately, despite our best efforts, Sunday usage remained low.”
Cllr Carter claimed that numbers of people using buses across the network was falling, and this was the exact opposite to the shift towards the use of public transport which the council wanted.
He said there needed to be a review of why people were not using the Park and Ride service.
Cardiff Council have been contacted for comment.
