A blue-ribbon transportation panel will ask lawmakers to consider bolstering the state’s flagging Transportation Trust Fund by raising tolls and imposing new or increased vehicle registration fees. The 31-member Transportation Revenue and Infrastructure Committee’s interim report is more of a menu of options for lawmakers to consider than a series of prescriptions.b “We’ve covered a lot of territory in a period of time,” said Frank Principe, who chairs the commission. “We also understand there’s a lot more to dig into and I don’t take that lightly. We certainly want to provide as much helpful input that we can in terms of trying to move these kinds of topics and conversations forward.”
