Maryland Zero Emission Vehicle Infrastructure Plan

Suitability Analysis

As part of Zero Emission Vehicle Infrastructure Plan (ZEVIP), the Maryland Department of Transportation (MDOT) developed a suitability analysis tool to support investment of electric vehicle (EV) charging infrastructure in Maryland. This tool builds 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.

Methodology

The Tool utilizes 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.
