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.
