How is Transportation scored?
Transportation uses two measures: public EV charging ports per 1,000 registered vehicles, and zero-emission vehicles' share of current-model-year registrations. On each, the leading community scores 100 and every other community scores in proportion to it. The Transportation Topic Score is the average of the two.
| Measure | Measured as | Better when | Worth up to |
|---|---|---|---|
| EV charging-port density | per 1,000 registered vehicles | Higher | 100 |
| ZEV share of current-model-year registrations | share of current-model-year registrations | Higher | 100 |
