Brian D. Taylor, director of the Institute of Transportation Studies at UCLA Luskin, spoke to the Orange County Register about the opening of new express lanes on the 405 Freeway. Motorists who use the two express lanes on 16 miles of the freeway in Orange County will have the option of paying a toll or carpooling. The lanes will be free to three-person carpools, but two-person carpools during rush hours will need to pay. Taylor, a professor of urban planning and public policy, said express lanes help keep traffic flowing compared to general lanes. For example, the two express lanes on the 91 Freeway carry about 45% of its total traffic. “Those two lanes are operating so much more efficiently that more people are getting through as a result,” Taylor said.
