During peak traffic hours, many
cars are travelling from a downtown parkade to the nearest freeway on
ramp. The
traffic engineers have decided to widen the road
downtown to accomodate this heavy flow of cars traveling between
these
two points. Which roads should the engineers widen in order
to achieve this goal?
Below is a network that shows the roads connecting the parkade, node A,
to the freeway on-ramp, node G. The
arcs are labeled with
their directional flow.
ie: |

This
shows that A to B
has a capacity of 5, while B to
A has a capacity of 0. |
