Traffic Signal

Famous quotes containing the words traffic and/or signal:

“Irony, forsooth! Guard yourself, Engineer, from the sort of irony that thrives up here; guard yourself altogether from taking on their mental attitude! Where irony is not a direct and classic device of oratory, not for a moment equivocal to a healthy mind, it makes for depravity, it becomes a drawback to civilization, an unclean traffic with the forces of reaction, vice and materialism.”
—Thomas Mann (1875–1955)

“By day thy warning ringing bell to sound its notes,
By night thy silent signal lamps to swing.”
—Walt Whitman (1819–1892)
