An overwhelming majority of Massachusetts residents said they would not want to pay extra to drive to downtown Boston if that meant less traffic, dealing a blow to the idea of introducing congestion pricing in New England’s largest city, according to a new Suffolk University/Boston Globe poll.

Boston’s heavy traffic has long frustrated both commuters seeking to get into the city and climate activists who want to reduce reliance on cars to curb carbon emissions.

Under a city climate plan released in April, Mayor Michelle Wu said the city would study charging drivers to use roads in a bid to dissuade private vehicle trips.

More than 69 percent of the 500 registered voters surveyed in the Suffolk/Globe poll said they would not be willing to pay to drive to downtown Boston if there was less traffic. That far outpaced the 26 percent who said they would; 5 percent said they were undecided.

It’s not as if residents say driving around the state is getting any easier. Fewer than half of those polled — 46 percent — said their daily commutes have stayed the same over the last year, while another 32 percent said they had gotten “slightly” or “significantly” worse. Just 10 percent reported it had improved.

Patrick Mongeau, a second-grade teacher from Arlington, said he understands the arguments for policies to reduce traffic in Boston, but is not a fan of an extra fee to drive into the city.

He said he loves driving into Boston for events and concerts, and that for him, using his car is the “cheapest way” to get into the city.

“So making the cheapest way for me be more expensive . . . I would not love it,” said Mongeau, 42. “We don’t live close to any of the [train] stations. Getting to Alewife [Station] is almost as hard as getting to [Interstate] 93. There’s more traffic getting to Alewife than getting to 93.”

Wu’s climate plan includes a section of ideas to evaluate mechanisms to “reduce single-occupancy vehicle commuting,” including studying parking fees, tolls, and “congestion charges to discourage private vehicle trips, reduce congestion, and lower emissions.”

A spokesperson for Wu did not respond to a request for comment on the poll results and questions about whether the study had started.
