People take different roads seeking fulfillment and happiness. Just because they’re not on your road doesn’t mean they’ve gotten lost.
H. Jackson Browne
In the 1969 publication ‘Graphentheoretische Methoden und ihre Anwendungen’, W. Knödel remarked that
. . . major road investment in Stuttgart’s city centre, in the vicinity of the Schlossplatz, failed to yield the benefits expected. They were only obtained when a cross street, the lower part of Königstrasse, was subsequently withdrawn from traffic use. . . .
Eliminating a road, rather than building a road, improved traffic flow.
