1 Electric Vehicle Infrastructure Location Tool and Visualization Map Analysis and Methodology Overview February 2018

2 Agenda Electric Vehicle Fast Charging Infrastructure Planning Tools Overview & Analysis Goals Basic Methodology & Demonstration Example Results & Uses 2

3 Analysis Objective Support states and other stakeholders in assessing fast charging along corridors and priority locations for charging stations 3

4 Key Analysis Parameters MJB&A utilized a GIS platform to collect and organize data on over 4,000 miles of freeway in the 11-state Transportation & Climate Initiative region Assessed DC Fast Charging (DCFC) opportunities along all the designated federal corridors plus additional state priority corridors For the existing network, included public, non-proprietary DCFC infrastructure within 5 miles of freeway corridors Focused on interstate exits as sites for corridor fast charging Worked with TCI state participants to refine dataset, parameters, and metrics 4

5 Inputs: Key Metrics Proximity to Existing Charging Commercial Activity Population Traffic Density Distance to nearest DCFC station and density of existing stations Number of restaurants, bars, and gas stations within 1 mile of each exit Population density of surrounding county Average annual traffic volume of freeway segment 5

6 Methodology: Overview Each exit is compared to all other selected exits within each metric Each exit is scored between 1 and 10 for each metric: an exit could be a 1 for population density (i.e., very low population) but a 10 for proximity (i.e., there are no existing DCFC nearby) Metrics are then combined through a range of ranking methods to assign each exit one cumulative score; all scores are then ranked Tools allow a user to adjust the weighting of metrics and design a ranking method that reflects personalized priorities Proximity (Nearest) Proximity (Density) Traffic Volume Pop. Density Comm. Activity Nearest existing infrastructure very close Nearest existing infrastructure very far 1 10 Many charging ports nearby No charging ports nearby 1 10 Low traffic volume on freeway near exit Very high traffic volume on freeway near exit 1 10 Low population density near exit Very high population density near exit 1 10 No points of interest within 1 mile of exit Many points of interest within 1 mile of exit

7 Resource: Infrastructure Location Identification Tool Identification Tool Options Region: Full TCI or individual state Exit Group: All in region, Gap Exits, or specific corridor Weighting method: one of six preloaded or custom 7

8 Infrastructure Location Identification Tool: Ranking Methods 1. Through Traffic 2. Gap Proximity Metrics Nearest DCFC Density of DCFC 3. High Traffic Gap 4. Traveler Use + User Defined Demand Metrics Traffic Density Population Density? Convenience Metrics Commercial Activity 5. Resident Use 6. Even 8

9 Resource: Visualization Map The Visualization Map allows the user to see all metric data (e.g., population density and traffic volume) as well as the outputs from the Identification Tool in order to compare possible locations for DCFC infrastructure deployment Through Traffic Method Fill Gaps Method Low Suitability High Suitability 9

10 Western Maryland Example 10

11 Western Maryland Example: Results from Through Traffic (Default) Method Fairly even weighting, but with highest weighting on Demand Metrics, lower emphasis on Proximity and Convenience 287 of 316 Low Suitability High Suitability 11

12 Western Maryland Example: Results from Fill Gaps Method Higher weighting on Proximity Metrics, lowering emphasis on Demand and Convenience 89 of 316 Low Suitability High Suitability 12

13 Possible Analytical Questions Is a given location a good candidate for new charging infrastructure? Where are the best locations in my state to locate new charging stations? How do two locations compare for new charging station development? Where is a good location to build a charging station to fill gaps in the charging network? 13

14 Tool Availability Tools are available for free from either M.J. Bradley & Associates or Georgetown Climate Center websites
