| Changing trends in public transit lead to innovative strategies |
| Research shows a concerning trend in transit ridership. Overall transit ridership is down. Bus ridership is down the most in mid-size cities (populations of 200,000 500,000), and, after six years of consecutive decline, it is at its lowest point overall since the 1970s. Exceptions to this new downturn is commuter rail and demand-responsive... |
