5.6 A section of highway has the following flow-
density relationship q = 50k - 0.156k2 [with q in veh/h
and k in veh/mi]. What is the capacity of the highway
section, the speed at capacity, and the density when
the highway is at one-quarter of its capacity?
8.20 Two routes connect a suburban area and a city,
with route travel times (in minutes) given by the
expressions t₁ = 6 + 8(x₁/c₁) and t₂ = 10 + 3(x2/c2),
where the x's are expressed in thousands of vehicles
per hour and the c's are the route capacities in
thousands of vehicles per hour. Initially, the
capacities of routes 1 and 2 are 4000 and 2000 veh/h,
respectively. A reconstruction project on route 1
reduces the capacity to 3000 veh/h, but total traffic
demand is unaffected. Observational studies note a
35.28-second increase in average travel time on route
1 and a 68.5% increase in flow on route 2 after
reconstruction begins. User-equilibrium conditions
exist before and during reconstruction. If both routes
are always used, determine equilibrium flows and
travel times before and after reconstruction begins.
