COMMENTS: Green Light
Traffic congestion is such an apt topic for a nightly newscast, since so many of its viewers must have freshly survived its rigors in order to arrive in front of the television set to watch the story. NBC's Tom Costello contributed his latest addition to this list of previous efforts. How can delays be cut by at least 15%? How can emissions be cut by 22%? How can fuel consumption be cut by 10%? The answer: improve traffic lights. It costs $3,000 to modernize each intersection, Costello reported: just add traffic sensors, install cameras, coordinate signals and constantly adjust the duration of lights as traffic patterns shift.
