Luskin Urban Planning’s Michael Manville commented in a recent Boston Globe story on Massachusetts Gov. Charlie Baker’s rejection of an attempt to alleviate the city’s traffic congestion through a toll discount for off-peak commuters. Baker sent a previously approved pilot provision back to the Legislature to conduct a new study of the growing problem. “Massachusetts is a natural place to try this,” said Manville, who grew up north of Boston. “It’s the kind of place that can be bold and do an experiment like this.”
