Arlington gets to work installing sensors, drawing parking spots for future ‘performance parking’ pilot

While road repaving season has kicked off in Arlington, crews are working on

While road repaving season has kicked off in Arlington, crews are working on local roads for another reason.

They are installing traffic sensors in and marking some 4,500 parking spots in the Rosslyn-Ballston and Pentagon City-Crystal City corridors.

The spots and hardware are the foundation for a three-year, $5.4 million state-funded pilot project testing out a new way to manage parking availability and pricing, dubbed "performance parking," which kicked off earlier this year.

Currently, parking is at a fixed rate and people have to find spots once they arrive at their destination, which can lead to double-parking or going somewhere else to, for instance, grab a meal.

Using existing meters and keeping the Parkmobile payment platform, the pilot intends to smooth out competition for convenient spots by directing people to cheaper options farther away. Prices would also vary based on time of day.

Arlington County will have a phone-friendly website with real-time availability and pricing data, which may also be accessible from some third-party apps. This information could help people plan where to park ahead of time, decreasing cruising time.

The pilot "is data-driven, using technology to better understand existing park utilization," Melissa McMahon, the parking and curb space manager for Arlington County, told the Planning Commission this week. "We are actively managing parking supply to make parking more convenient and to reduce the negative impacts of hard-to-find parking."

To get started, the county has to understand how people use on-street parking right now. Crews are delineating discrete spaces where, currently, it is a free-for-all between two signs, and installing one sensor per space.

Later this year, these wireless, battery-operated, in-ground sensors will start sensing when and for how long a car occupies a space. They will communicate that to "wireless gateways" located on traffic signal poles, which will relay that data to a central network server. That data is converted into a dashboard that county staff will use to make parking decisions.

Once it has enough "existing conditions" data this fall, the Dept. of Environmental Services will pick a range of prices, which it aims to bring to the Arlington County Board for approval this December. After that, for the next two years of the pilot, DES will request permission to change prices once per quarter to see the impact on driver behavior.

"This project does not create dynamically or fast-changing metered pricing," McMahon said. "It won't be uncertain on a day to day basis. If you’re going into a neighborhood routinely you’ll have a sense of where the lower price spots are and where the higher priced spots are."

She said the goal is not to increase overall meter revenue, and blocks with lower rates may cancel out those with higher rates.

DES is visiting local businesses and hosting calls with economic development groups to alert them to the changes. One concern was whether this will hurt employees but McMahon says the opposite is true.

"You might not want your employee parking in front of your business because you want your customers parking there," she said. "Having nearby lower prices provides a feasible, understandable alternative to an employee who has a whole shift to work, who wants to pay a lower price and might be willing to walk a couple blocks."

One benefit of cheaper blocks could be that it gets people out of neighborhoods with free parking.

"Where people don't use meters and park somewhere else because they don't want to pay, we might see opportunities to reduce the price," McMahon said. "If we lower the rate to get underutilized meters better-utilized, that could pull people out of the neighborhoods."

That was a relief to Planning Commission member Nia Bagley, who described "empty meters and full neighborhoods with people that really should be in a meter and should not be in the neighborhoods."

Using the data, the county will also be able to approximate where people are more or less likely to pay for parking, which could eventually inform how meter attendants are dispatched.

People sometimes skip payment because they are picking up or dropping off deliveries. Zones for this activity popped up during the pandemic and have since been converted into short-term spots, but there seems to be a desire to have such zones added in the future.

"If we’re going to be making parking a little more restrictive and expensive, something we’ll need to focus on going forward with our site plans is that there's adequate pick up and drop off," Commissioner Elizabeth Gearin said.

The county is collecting feedback on the goals of the program through this summer. More information is available on its website. Some feedback opportunities are planned before the the County Board adopts pricing changes.
