8.19 Three routes connect an origin and a destination
with performance functions t₁ = 8+ 0.5x1, t2 = 1 +
2x2, and t3 = 3 + 0.75x3, with the x's expressed in
thousands of vehicles per hour and the 's expressed
in minutes. If the peak-hour traffic demand is 3400
vehicles, determine user-equilibrium traffic flows.

8.4 Consider a Poisson regression model for the
number of social/recreational trips generated during
a peak-hour period that is estimated by (see Eq. 8.3)
BZ = -0.75 +0.025(household size) + 0.008(annual
household income, in thousands of dollars) +
0.10(number of nonworking household members).
Suppose a household has five members (three of
whom work) and an annual income of $100,000.
What is the expected number of peak-hour
social/recreational trips, and what is the probability
that the household will not make a peak-hour
social/recreational trip?
