Spatiotemporal Effects of Segregating Different Vehicle Classes on Separate Lanes

In this paper, the authors report that using spatiotemporal analysis of real freeway traffic reveals that carpool lanes are not as damaging as previously reported. Studying carpool lanes on five freeway sites in the San Francisco Bay Area, the authors instead discover an unexpected benefit of carpool lanes that should be even greater when special lanes are used to segregate very different vehicle classes, such as buses and cars. The authors then show how reserving lanes on freeways and city streets for bus-use only can favorably affect not just buses, but also cars.
