This layer provides low utilization results where:
A Public Level 2 charger that is located within an eighth of a mile of households, defined as walking distance, can adequately serve 3 EVs that likely lack home charging (2 EVs overnight on separate days and 1 EV during the day)
A Public DC fast charger that is located within two miles of households, defined as in the neighborhood, can adequately serve 20 EVs that likely lack home charging during the day (DC fast chargers would not be used for long-duration overnight charging)
The quarter-mile hexagons show results that are based off model estimates:
The "ev_no_walk" field can be used to identify areas for public Level 2 charging deployment that would capture charging demand within walking distance (1/8th mile) of households with EVs that likely lack home charging and also lack sufficient existing public Level 2 charging within walking distance.
The "ev_no_2mi" field can be used to identify areas for public Level 2 and DC fast charging deployment that would capture charging demand within the neighborhood (2 miles) of households with EVs that likely lack home charging and also lack sufficient existing public Level 2 or DC fast charging within the neighborhood.
