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?
8.15 An origin-destination pair is connected by a
route with a performance function t₁ = 8+ x1, and
another with a function t₂ = 1 + 2x2 (with x's in
thousands of vehicles per hour and t's in minutes). If
the total origin-destination flow is 4000 veh/h,
determine user-equilibrium and system-optimal route
travel times, total travel time (in vehicle minutes),
and route flows.
8.13 Consider the situation described in Problem
8.11. If the total number of trips remains constant,
determine the amount of amusement floor space that
must be added to destination 2 to attract an
additional 50 social/recreational trips.
