Aine Groogan, from the Northern Ireland Green Party, said congestion in Belfast cost drivers more than just money.
“Many people have experienced the frustration of traffic jams in and out of our towns and cities, particularly at peak commute times," she said.
“However, congestion creates more than just annoyance – it costs money and it impacts on our mental and physical health.
“The study shows that an average of 190 hours spent in congestion costs £1,400 per driver in lost time.
“Congestion causes air pollution which contributes to 550 deaths per year across Northern Ireland from respiratory illnesses.
“There are too many car parking spaces in Central Belfast and we haven’t invested enough in modern public transport provision."
Ms Groogan said the new Glider system in Belfast has brought an extra 30,000 passengers per week into the public transport system and has reduced traffic by a quarter along the corridors.
She added: “The Green Party is pushing the case for a green transport plan for Belfast which improves the health and well-being of all our citizens.”
Trevor Reed, transportation analyst at Inrix, said: "Congestion costs Brits billions of pounds each year. Unaddressed, it will continue to have serious consequences for national and local economises, businesses and citizens in the years to come.
"In order to avoid traffic congestion becoming a further drain on our economy, it is increasingly obvious that authorities need to adapt.
"With the help of new and innovative intelligent transportation solutions, we can being to tackle mobility issues we face today."
