Dedicated bus lanes improve safety

The U.S. DOT is funding bus projects across the country that promise many of the same benefits as rail, but at lower cost. With dedicated lanes and stations that are more like train stops than a typical American bus stop, bus rapid transit (BRT) aims to move large numbers of people through congested areas faster than rush hour traffic. This sometimes comes with tradeoffs, like the loss of regular traffic lanes, but it can also offer unanticipated safety benefits, like curbing excessive traffic speeds, according to new research. 

Speeding up buses with automated enforcement

Transit-exclusive lanes can speed buses or other transit vehicles and make the services more appealing and predictable. But those nearly-empty lanes can seem appealing to the drivers of private vehicles stuck in traffic or looking for short-term parking or loading, so keeping the lanes clear for transit can be a challenge. Cameras currently being used to enforce speed or red-light running, as well as cameras mounted on the buses themselves, might improve enforcement, as suggested by a recent Mobility Lab post.
