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.
Suppose that the projected road vehicle traffic flow in a corridor is 5000 vehicle-trips per hour
in one direction. The average perceived user cost functions of the two major highways (Route
1 and Route 2 in the corridor are as follows (in dollars):
Route 1: Ci =1 +8(qı/5000)
Route 2: C2 = 1+10(q2/2500)
Where: qi and q2 are the traffic flows on Route 1 and Route 2 respectively.
Calculate the volume of traffic during the peak hour on each route, if users were free to
choose their own routes.
Two routes connect an origin and destination with performance function t; = aj + (xj/cj)2 (with t's in minutes and x's in thousands of vehicles
per hour). It is known that at user equilibrium, 65% of the origin-destination demand takes route 1. How many vehicles (in thousands) will
take route 1 if system optimal equilibrium is archived?

The current toll is $1.35/veh. It has been found from past experience that the daily traffic volume will decrease by 400 veh/day for each 25¢ increase in toll. Therefore, if x iš the increase in toll in cents/veh, the volume equation for veh/day is V= 4500 - 400 (x/25), and the new toll/veh would be T = 135 + x. In order to maximize revenues, what would the new toll charge be per vehicle, and what would the traffic in veh/day be after the toll increase?arrow_forward
