again, there are no traffic lights on H1 or H2, so how are traffic lights going to reduce traffic congestion.  traffic lights only regulate traffic flow, they do not reduce congestion, there are only  2 ways that can reduce traffic congestion - build more roads or reduce the number of cars using the freeway at the same time.   there are no plans to build new freeways, so the only logical choice is to reduce the need for cars, and rail and tods will accomplish this.
