An S9 limited-stop bus using the Metrobus Express livery.

Ridership is up on WMATA’s three flagship bus corridors that have limited-stop operations during rush hour. Since initiating limited-stop operations, ridership is up 8% on the 16th Street line, 9% on the Georgia Avenue line, and 3% on the Pennsylvania Avenue line. These are big numbers, considering it costs virtually nothing (and may save money) to run buses that stop less frequently but use all the same existing infrastructure otherwise.

If we can get these sorts of results just by rearranging the service, imagine what results we might get with a dedicated lane.
