As part of Zero Emission Vehicle Infrastructure Plan (ZEVIP), the Maryland Department of Transportation (MDOT) developed a set of suitability analysis tools to support investment of electric vehicle (EV) charging infrastructure in Maryland. These tools build upon MDOT’s previous work under the National Electric Vehicle Infrastructure (NEVI) Program and the EV Charging Siting Tool to identify areas within Maryland best suited for charging infrastructure. 

EV Corridor Charging 

The EV Corridor Charging Suitability Tool supports the investment of Direct Current (DC) Fast charging infrastructure along Maryland’s 23 designated EV Alternative Fuel Corridors (AFCs) in order to build redundancy within Maryland’s EV charging network.

Neighborhood & Amenity EV Charging 

The Maryland Neighborhood and Amenity EV Charging Suitability Tool supports the deployment of publicly available light-duty EV charging infrastructure within Maryland communities where people gather or currently stop in order to increase equitable access to publicly available EV charging infrastructure.

High Density Residential EV Charging 

The High Density Residential EV Charging Suitability Tool prioritizes the deployment of publicly available light-duty EV charging infrastructure adjacent to Multi-Unit Dwellings (MUDs) as well as prioritizes curbside charging needs for urban and nonurban communities that do not have dedicated driveways or home garages in order to increase equitable access to charging.

Workplace EV Charging 

The Workplace EV Charging Suitability Tool facilitates convenient charging access for employees at dedicated work locations by provide charging for drivers with limited or no access to at-home charging and long commutes.

Methodology 

The Tools utilize hexagonal binning (hexbins) to weight and aggregate federal and state data layers in order to support investment in charging infrastructure. Unlike census tracts or zip codes, which vary in size, these hexbins allow for an apple-to-apple comparison of areas within Maryland. 

Data within each hexbin was aggregated, and a weighted score was applied based on MDOT’s priorities, resulting in a visualization of the most suitable locations for the installation of DC Fast charging infrastructure along Maryland’s AFCs. 

The methodology and data layers will be updated as necessary, based on the need for charging infrastructure within Maryland.
