This week on TOWN HALL Journal, Judy Muller discusses the promises of mass transit and the woes of traffic with CEO of Los Angeles County Metropolitan Authority, Art Leahy. Leahy outlines the expansion of the gold line, the subway to the sea, fare-based carpool lanes and other proposed solutions to our transportation problems. Our vault segment takes you back to 1980 when light-rail trains crisscrossing the city was the solution du jour. Muller also explores the future of interstate transportation via high-speed trains.
