The Public Transport Users Association has called for a vote for the Greens in this week's election and condemned the Napthine government's "betrayal of the Victorian people" in seeking to build the East West Link.

The volunteer advocacy group endorsed the Coalition ahead of Labor this time four years ago for its superior public transport policies but argues the government has turned its back on those since coming to power, instead building a multi-billion-dollar road for which it has no mandate.

"No matter how much the government denies it, the East West Link will be a drag on transport budgets for the next quarter century. Stage one alone will cost well over $15 billion in up-front costs and availability payments," PTUA president Tony Morton said in a release accompanying the party's election scorecard.

"East West Link is a betrayal of the Victorian people, who elected the Coalition in 2010 on the back of fixing public transport, not building more roads."
