The state legislature’s Transportation Committee is gearing up for a busy fall, with public hearings on Gov. Charlie Baker’s $18 billion transportation bill and another session likely to probe Registry of Motor Vehicles failings.

Chairs Rep. William Straus and Sen. Joseph Boncore announced Tuesday that the committee will hear testimony on Oct. 8 on the $18 billion transportation borrowing bill Baker filed last month. His proposal would direct billions of dollars more to the MBTA, boost funding available for road and bridge improvements, and direct future revenue from the multi-state Transportation Climate Initiative – whose money-generating mechanics still have not been announced – to public transit.

One of the most-discussed proposals in the bill is a $2,000-per-employee tax credit to promote telecommuting, a change that Baker said could help reduce roadway congestion but which some critics have called a giveaway to employers, many of which already have some form of work-from-home policy.

Also on the docket for the fall is a broad debate on transportation funding, though that will likely come before the full House rather than just before the Transportation Committee. House Speaker Robert DeLeo has pledged that his branch will debate a range of revenue options when it returns.

Among the options that members have raised, DeLeo said earlier this month, is another pass at tying the state’s gas tax to inflation, something that was included in a 2013 bill and then repealed by a ballot initiative a year later.

Straus has expressed support this session for increasing the gas tax as a way to generate revenue for the state’s growing transportation infrastructure needs.

The effort to find ways to direct more resources to the state’s flagging transportation systems will compete for the committee’s attention with efforts to hold the Registry of Motor Vehicles to account for failing to process years’ worth of notifications from other states that local drivers should have their licenses suspended for various violations. Those lapses led to a Massachusetts-licensed commercial driver killing several motor cyclists in a New Hampshire crash earlier this year.
