8.21 Three routes connect an origin and destination with performance functions t₁ = 2 +0.5x₁,₂ = 1 + x2 and 13 = 4 + 0.2x, (with f's in minutes and x's in thousands of vehicles per hour). Determine user- equilibrium flows if the total origin-to-destination demand is (a) 5000 veh/h.
a) Table 4 indicates an urban zone’s expected household composition at some future year
and the calibrated educational-based trip rates. Estimate the total educational-based trips
in terms of "y" that the urban zone will produce on a typical day in the horizon year.
