What’s the worst part about your commute? Leaders want to know. Seriously.

There’s a plan to spend more than $330 $23 billion on transportation improvements in Northern Virginia by 2040.

That plan is called “TransAction 2040,” and transportation planners want you to become more familiar with it. A meeting will be held from 10 a.m. to noon on Saturday in Manassas Park where consultants from the Northern Virginia Transportation Authority — the agency that approves and doles ranks regional transportation projects making them eligible for state funding  — will ask a simple question: What’s wrong with your commute.

Obviously, if you live in Northern Virginia, there’s not one simple answer.

The responses will be used to update TransAction — a long-range planning guide that identifies what roadways need improvements, and how to better fund and expand transit. The list also serves as a way to tell state legislators in Richmond about the problems Northern Virginia drivers face on a daily basis.

“NVTA is one of the most progressive approaches to traffic control that I’ve seen,” said Manassas City Councilman Jonathan Way. “They monitor transportation funding, something that we in Northern Virginia value very much because we’re putting more money in than we’re getting back.”

Consultants will use the feedback as they implement updates to the TransAction2014 plan.

The program is separate from the more than 20 projects evaluated by the state for possible funding. The plans were reviewed for their potential to reduce traffic delays, congestion, and to increase access to jobs within a 45 to 60-minute time span by the year 2020.

At the top of the list: Improvements to the Interstate 66 / Route 28 interchange in Centreville.

NVTA will hold a workshop on its TransAction plan at the Manassas Park Community Center. It is open to the public.
