Charging Ahead: Feasibility Studies for EV Stations by JMT
JMT prepared a feasibility study and design for the installation of EV charging stations at various Maryland Transportation Authority toll locations.
Location: Newburg, MD
Client: Maryland Transportation Authority
Electric Vehicle Charging Stations Level 1 (120V), Level 2 (240V) (208V), and Level 3 (480V) were evaluated for installation at the following locations:
- Point Breeze Office Complex
- Chesapeake House Travel Plaza
- Ft. McHenry Tunnel EZ Pass Stop-In Center
- Baltimore Harbor Tunnel EZ Pass Stop-In Center
- Maryland House Travel Plaza
Within each level, there were various manufacturers and features available including different amperages. Level 1 charging generally provides 4 miles, per hour of charge; Level 2 provides about 25 miles, per hour of charge; and Level 3 provides around 100 miles, per hour of charge. Dual charging stations were proposed for two locations to accommodate four parking spaces. The charging stations were designed to provide power to the vehicles through an SAE J1772 connector, which is the standard for most electric vehicles.
Driving Environmental Change: Solar PV Feasibility in New Jersey
JMT performed a solar electricity feasibility study throughout the PSE&G electric grid within NJ DOT rights-of-way.
Location: New Jersey PSE&G electric grid operating area
Client: Petra-Solar, Inc. via PSE&G
The Feasibility Study provided Petra Solar with several alternatives concerning the installation of solar panels along NJDOT Right-of-Way throughout the entire PSE&G electric grid. The study focused on several primary areas which included: 1) Canopy structures located in the median of interstate highways, 2) Canopy and ground mounted structures located in large infields and along the right-of-way of secondary highways also known as Land Service Highways, 3) NJDOT owned maintenance yards and or office building parking areas, 4) Ballasted ground mounted solar arrays in a DOT owned landfill, and 5) Solar panels attached to overhead or cantilever sign structures and noise walls. The study will be utilized to provide information to PSE&G and the BPU concerning future development of solar energy in the state of New Jersey along the NJDOT right-of-way.
JMT was responsible for determining where each location will tie into the grid and utilizes Petra-Solar panels which include an individual inverter converting the DC production of the panel into 120VAC. This helps reduce voltage drop when wiring panels together allowing for 3 phase power, which will then be transformed up to a higher utility voltage as required for each site.
Greener Roads Ahead: Planning for Connected and Automated Vehicles
JMT developed the Connected and Automated Vehicle (CAV) Technology Deployment Dashboard illustrating potential locations for CAV-related technology, project phase, and associated costs.
Location: Maryland
Client: Maryland State Highway Administration
JMT is supporting SHA’s Innovative Performance Planning Division (IPPD) in researching emerging transportation technologies to assess impact on SHA’s services and programs, and assist with developing and implementing strategies, policies and programs that leverage these new technologies.
JMT reviewed research and white papers and provided briefings on emerging topics related to CAVs. Topics ranged from the potential impact of CAVs on land use, to possible applications of CAV-generated big data for planning and performance assessments. JMT also reviewed federal and state guidance on CAVs and provided comments for incorporation into State responses to regulatory agencies. JMT developed draft CAV reference and outreach materials for MDOT SHA, including a website for showcasing agency initiatives and accomplishments, an interactive Story Map summarizing CAV policies and activities across the US, and an outreach strategy for working with Metropolitan Planning Organizations (MPOs) to coordinate CAV activities in Maryland.

This involved a meticulous inspection of electrical system components and a thorough assessment of their condition. The project started with JMT validating MPA Engineering’s electrical asset data requirements, ensuring all necessary information was captured during the inspection and condition assessment. JMT mapped the above-ground electrical features using advanced surveying techniques and converted them into GIS format. The team configured Esri’s Field Maps application to facilitate the condition assessments. The JMT team collected and assessed over 2,700 electrical features at Dundalk Marine Terminal, MPA’s busiest terminal.
The final dataset will play a pivotal role in guiding decisions on maintaining existing electric utilities and determining optimal locations for new installations. This project supports enhancements to the terminal’s power infrastructure and underscores MPA’s commitment to strengthen environmental initiatives. JMT was responsible for determining where each location will tie into the grid and utilizes Petra-Solar panels which include an individual inverter converting the DC production of the panel into 120VAC.
