A city-run bus system? Parking meter prices that fluctuate by the hour?

They may sound far-fetched, but those are some of the recommendations that have landed on Mayor Martin J. Walsh’s desk.

Without fanfare, Walsh’s transportation transition team released a report earlier this month on how to improve the city’s transportation system. Most of the conclusions were unsurprising: encourage more people to bike, walk, and take transit; continue Hubway; crack down on double-parking. And there were lots of wonky policy recommendations, such as “establish culturally-sensitive and linguistically appropriate mechanisms for accountability and public engagement in decision making” and “create and appoint a transportation advisory committee.”

But sprinkled throughout the 21-page report — compiled by a host of transportation advocacy groups chosen by Walsh’s staff, along with a former state transportation secretary and the current heads of the MBTA and the Registry of Motor Vehicles — there are some pretty unconventional ideas that could ruffle a few feathers.
