Martin Wachs, professor emeritus of urban planning, spoke to the Orange County Register about the prospect of converting carpool lanes to toll lanes on Orange County freeways. Seventy-seven percent of Orange County carpool lanes don’t meet the federal law’s requirement to move at a speed of 45 mph or faster. Turning carpool lanes into toll lanes would help unclog the flow of traffic because drivers willing to pay for access would move out of the general-purpose lanes, Wachs explained. “In every case, the facility is carrying more people than it would have had the lane either been not tolled at all, or remained a high-occupancy-vehicle lane alone.”
