The EV charging station at the Kahului Park & Ride on Maui consists of four 150 kW DC fast chargers with Combined Charging System and CHArge de MOve ports. The station – located along Route 380, also known as the Kuihelani Highway – cost $3 million to design and build, with $2.4 million coming from the NEVI program and $600,000 from the state’s highway fund.

“Providing drivers with the opportunity to choose alternatives to vehicles with traditional internal combustion engines is a critical part of the strategy to get Hawaii to a clean energy portfolio by 2045,” said Ed Sniffen, director of the Hawaii DOT, in a statement.

“When we began planning our department’s conversion to EVs we calculated an estimated annual reduction in CO2 (carbon dioxide) emissions of 8,700 pounds per vehicle, which is roughly the amount of energy used by an average American home in half a year,” he added.

[Editor’s note: In June 2023, Hawaii DOT deployed the state’s very first autonomous all-electric passenger shuttle bus. Developed in collaboration with the University of Hawaii at Mānoa, the AV Star All-Electric Autonomous Min-E Bus is an Americans with Disabilities Act-compliant vehicle that can hold 14 passengers or 10 passengers and two passengers in wheelchairs. The vehicle is also equipped with the Perrone Robotics “TONY” system – short for “To Navigate to You” – autonomous system that Perrone said meets all Federal Motor Vehicle Safety Standards.]

To qualify for NEVI funding, EV charging stations must meet criteria such as having EV charging publicly available 24/7 and being no more than one mile away from the nearest U.S. Department of Transportation-designated Alternative Fuel Corridor.

The Kahului Park & Ride along Kuihelani Highway was selected as the state’s first NEVI-funded EV charging site because it is accessible 24/7 and its location is adjacent to the Maui Alternative Fuel Corridors, the Hawaii DOT noted.

The agency added that EV charging will be free to the public at this location through March 10, as time-of-use rates are being finalized. Payment and charger availability can be checked through the EV Connect App at evconnect.com/ at that time, with payment via credit card also accepted at this EV charging locale, Hawaii DOT added.

Maryland Launches Zero-Emission Bus Pilot Program

Governor Wes Moore (D), the Maryland Department of Transportation, and the Maryland Transit Administration (MDTA) recently launched a “Zero-Emission Bus Pilot Program” at the MDTA’s Kirk Bus division in Baltimore, MD.

The pilot program is part of the MDTA’s broader effort to covert its transit bus fleet to zero-emission units – a program that is part of the governor’s commitment to reduce Maryland’s greenhouse gas emissions by 60 percent by 2031 and having the state rely on 100 percent clean energy by 2035.

Almost three years ago, the MDTA – which is a division of the Maryland DOT – kicked off its plan to transition to zero-emissions buses, with a goal of having them comprise 50 percent of its transit bus fleet by 2030 as outlined by the Greenhouse Gas Emissions Reduction Act Plan.

The first seven zero-emission battery electric buses underwent commissioning and road testing before being deployed to regular service as a pilot to inform the transformation of the 750-bus fleet, the agency said.

“We continue our work to make Maryland the cleanest, greenest, and most sustainable state in the nation – and we are going to do it in a way that creates new pathways to prosperity for all, and not just some,” said Gov. Moore in a statement.

“I am proud that [this pilot program] launch is a step forward in our state’s environmental goals, and allows us to work alongside the Maryland Department of Labor to create new apprenticeship programs in bus maintenance,” he noted. “This is what partnership looks like as we work to make Marylander safer and more competitive. We don’t have to choose between tackling climate change and growing our economy – we can, and we will, do both.”

“MTA’s zero-emission electric buses are the next step in electrifying our transportation network to reach Maryland’s climate goals and invest in new training opportunities,” added Paul Wiedefeld, Maryland DOT secretary. “[This] new apprenticeship program with our union partners is specifically designed to train zero-emission bus maintenance mechanics and ensure our workforce has the tools and training needed to maintain the new fleet of zero-emission buses.”

“Transit is an essential part of reducing our carbon footprint and improving our environment,” said noted Holly Arnold, MDTA’s administrator. “Our Zero-Emission Pilot program is just one of the many ways we’re focused on creating a more sustainable future.”

FHWA Offering $250M in Congestion Reduction Grants

The Federal Highway Administration recently made $250 million available, over five years, in competitive grants to support multimodal solutions that reduce vehicular traffic and air pollution in heavily congested metropolitan areas across the United States.

The FHWA said its new Congestion Relief Program – created by the Infrastructure Investment and Jobs Act (IIJA) – is now accepting applications for the first round of grants via a notice of funding opportunity, which provides $150 million in grants for fiscal years 2022, 2023, and 2024. The agency stated that these grants are available to states, metropolitan planning organizations, cities, and municipalities for projects within urban areas with a population of at least one million.

[Editor’s note: The Ohio Department of Transportation recently unveiled new system designed to detect traffic congestion and subsequently warn motorists of dangerous “slow-downs” at 13 highway sites in and around major urban centers across Ohio identified by the agency as “high-congestion, high-crash” areas.]

FHWA added that its new Congestion Relief Program provides grants to projects that reduce highway congestion and the economic and environmental costs associated with congestion, including pollution from transportation emissions. The agency noted that the program also optimizes existing highway capacity and transit systems, improves coordination with transit, and encourages other modes of travel.

According to FHWA, eligible projects include the deployment and operation of integrated congestion management systems, certain transit and mobility services, and incentive programs encouraging travelers to carpool, use transit, or travel during nonpeak periods. The agency added that it will “give priority” to projects that advance multimodal solutions for heavy traffic volumes in urban areas experiencing a high degree of recurrent congestion.

[Editor’s note: The Colorado Department of Transportation launched a new Bus Rapid Transit or BRT program for the Denver region in November 2023 designed in part to reduced congestion-related travel delays for bus riders. The agency said that BRT is a high frequency service designed to be “more reliable, convenient, and accessible” than traditional bus service; reducing delay points that can typically slow regular bus service, such as making long stops or getting stuck in traffic at intersections.]

“Traffic congestion without multimodal options is a major problem throughout America, especially in large metro areas, significantly limiting mobility and reducing clean air quality in our cities – while diminishing productivity nationwide because of higher costs when people and goods are delayed in traffic,” said FHWA Administrator Shailen Bhatt in a statement.

“With this program, we’re aiming to tackle congestion and provide a higher standard of living and greater multimodal options and working for the people in populated areas,” he noted.

Kentucky Breaks Ground on Fast EV Charger Facility

Governor Andy Beshear (D) and Federal Highway Administrator Shailen Bhatt, along with several state and local officials, recently gathered at the Circle K convenience store and filling station in Richmond, KY, to break ground on the first electric vehicle (EV) fast charging station in the southeastern United States built with funds from the National Electric Vehicle Infrastructure (NEVI) program.

[Above photo by KYTC]

Developers of privately-owned fast charging stations, mandated to remain open to the public 24 hours a day, seven days a week, are obligated to finance a minimum of 20 percent of the construction and operational costs for the initial five years, while NEVI funding will cover the remaining expenses. At the event, the governor noted that his administration is also seeking proposals to install up to 16 additional stations along interstates and parkways statewide using NEVI funding – all part of Kentucky’s longer-term effort to add up to 40 new fast charging stations by 2025.

“To make sure Kentucky keeps leading the way, we’re building out our EV infrastructure so our families can charge up as they travel our great state,” Gov. Beshear said in a statement – noting that Kentucky is set to receive nearly $70 million from the NEVI program to accomplish that goal.

The Kentucky Transportation Cabinet is responsible for administering those NEVI funds and for building out the state’s EV recharging network.

“The number of registered EVs in Kentucky continues to grow, and we want to ensure current and future owners have a reliable network of charging stations to support long-distance EV travel,” said KYTC Secretary Jim Gray.

The Circle K Richmond location is one of two awarded sites Circle K will own and operate – becoming one of the fast-charging EV stations to be built across Kentucky.

That Circle K Richmond charging site will initially offer four 180 kilowatt fast chargers, each ready to recharge a typical EV in under 20 minutes. The units, initially equipped with standard Combined Charging System 1 connectors, will undergo upgrades to North American Charging Standard connectors later this year. This transition will occur after the finalization of national standards and UL certification to ensure support for all current and future EV makes and models.

“We’re very pleased to partner with the state in bringing EV fast charging to the commonwealth with the support of the NEVI program,” said Louise Warner, Circle K senior vice president of global fuels. “Partnerships like these are helping to accelerate the development of charging infrastructure to keep pace with growing demand and EV adoption.”

Podcast Interview: AASHTO President Craig Thompson

The latest episode of “The Stream by AASHTO” podcast – formerly the Environmental Technical Assistance Program or ETAP podcast – features Craig Thompson, secretary of the Wisconsin Department of Transportation and 2023-2024 president of the American Association of State Highway and Transportation Officials.

[Above image by AASHTO]

“The Stream by AASHTO” podcast is part of a technical service program for state departments of transportation provided by the American Association of State Highway and Transportation Officials. It explores a wide array of environmental topics that affect transportation and infrastructure programs.

For his term as AASHTO president, Thompson plans to focus on three key emphasis areas: Bolstering safety on America’s roadways, realizing the promise of the historic Infrastructure Investment and Jobs Act, and reinvigorating the transportation workforce.

During his podcast interview, President Thompson shares insights into his presidential emphasis areas. Listen to this episode to gain a deeper understanding of this year’s AASHTO president and explore how his extensive experience has shaped AASHTO’s strategic focus for the 2023-2024 year.

[Editor’s note: AASHTO recently released a “presidential profile” video of Thompson, which can been viewed below.]

In his role as the Wisconsin DOT secretary, Thompson oversees one of the largest state agencies, boasting a workforce of over 3,100 employees and managing a biennial budget exceeding $8 billion. The department includes the Division of Motor Vehicles, serving approximately 50,000 customers weekly, and the Division of State Patrol, responsible for law enforcement and assisting motorists across the state.

Thompson also brings over 30 years’ worth of transportation industry experience to his role as AASHTO president. In 2020, he was president of the Mid America Association of State Transportation Officials and was the executive director at the Transportation Development Association of Wisconsin.

Joint Office Issues $46M for EV Infrastructure Grants

The Joint Office of Energy and Transportation or JOET – jointly operated by the U.S. Department of Transportation and U.S. Department of Energy – has issued $46.5 million in grants to 30 projects across 16 states and Washington, D.C, to help develop electric vehicle or EV infrastructure in rural, urban, and tribal communities as well as expand what it calls the “clean energy” workforce.

[Above image via the JOET]

The JOET added that this funding will also address barriers to charging in multifamily housing facilities, explore new approaches to curbside charging in urban areas, promote seamless connections across modes through e-mobility hubs, and test new incentive structures to provide affordable public charging access.

“[We are] proud to fund these game-changing clean transportation projects in communities across the country,” said Gabe Klein, the JOET’s executive director, in a statement.

“These investments ensure we can meet unique local needs, create good-paying jobs, innovate new business models, test products thoroughly, and work towards our goal of making it easy for everyone to ride and drive electric,” he added.

The JOET has also helped developed a variety of resources to help support the expansion of EV infrastructure across the country.

For example, in conjunction with the USDOT, the JOET helped issue a technical resource in July 2023 designed to aid larger communities take full advantage of federal funding for electric vehicle charging stations and other forms of electric transportation.

That guide – called “Charging Forward: A Toolkit for Planning and Funding Urban Electric Mobility Infrastructure” – provides a comprehensive resource for communities, metropolitan planning organizations, transportation providers, businesses, and property owners and developers by including information on how to scope, plan, and identify ways to best leverage billions of dollars in funding from the Infrastructure Investment and Jobs Act or IIJA.

It follows on the heels of the Rural EV toolkit originally issued by the USDOT in 2022 and later updated in 2023. 

The toolkit builds on the efforts of the Joint Office to provide states and communities across America with information and assistance to accelerate an electrified transportation system that is convenient, affordable, reliable, and equitable. It also includes guidance to help urban areas implement other forms of electric transportation, such as public transit, electric bikes and scooters, and ride-share services, USDOT said.

Connecticut DOT Seeks to ‘Quiet’ Interstate Pavement

The morning and afternoon commutes along Interstate 95 in southwest Connecticut will still be a little congested, but maybe a little quieter, thanks to “quiet pavement” the Connecticut Department of Transportation plans to install as part of a road resurfacing project.

[Above photo by Connecticut DOT]

The three-lane (each way) 6.7-mile stretch of I-95 from the New York state line to Stamford carries about 135,000 vehicles a day, much of which is commuter traffic to and from New York City. A Connecticut DOT project to repave the interstate will include a specialty asphalt mix designed to absorb more noise than concrete and last longer than traditional asphalt.

The impetus behind using this “quiet pavement” derived from feedback from people who live and work in the area; they asked the agency to do something about the interstate noise. Some residents had even created a group, Neighborhood Citizens Against I-95 Noise, to push Connecticut DOT to undertake some noise abatement measures.

The department got the message, explained Garrett Eucalitto, Connecticut DOT’s commissioner.

“We seek out resident, business, and stakeholder input when any project is undertaken,” explained Eucalitto, who also serves as the 2023-2024 vice president for the American Association of State Highway and Transportation Officials. “These groups know the needs of the area, and their insights are valued and appreciated.”

While quiet pavement is not an official Federal Highway Administration noise mitigation method, Eucalitto said the asphalt mix is “expected to reduce highway noise by two to three decibels.”

Andi Karica, resident engineer on this Connecticut DOT paving project, said crews will begin removing existing pavement this spring and replace it with a one-inch Binder Rich Intermediate Course topped with two inches of Stone Matrix Asphalt.

“It’s a completely different mix design that takes different ratios of binder and stone aggregate,” Karica said. “It’s a sticky mix, a little harder to work with, but it should be more durable and translate to less noise.”

The Stone Matrix Asphalt is new to Connecticut DOT, but different forms of it have been around for many years. Most of the states that have used it – Arizona, California, Texas, Georgia, and Florida – have warmer climates, and many results show a two decibel reduction in noise.

“This type of asphalt has never been used before in Connecticut, so the Stamford and Greenwich Project will be a pilot program to ensure the longevity and durability of the materials,” Eucalitto said. “We look forward to seeing the results as we continue to deliver projects that improve safety and reliability for all roadway users.”

As the paving project gets started this spring, Connecticut DOT will continue managing a Planning and Environment Linkages study along I-95 that is looking at a broader range of environmental, economic, mobility, and safety issues along the corridor.

The study, which began in June 2023 and is scheduled to be completed in December 2025, will rely heavily on community input, and is designed to help the department develop specific projects.
