Two highways connect an origin-destination pair, having performance functions of t1 = 5 + 4(x1/c1) and t2 = 4 + 5(x2/c2) for routes 1 and 2, respectively. for the performance functions, the t's are in minutes and the flows (x's) and capacities (c's) are in thousands of vehicles per hour. the total traffic demand for the two highways is 4000 vehicles during the peak hour. initially, the capacities of routes 1 and 2 are 3500 veh/h and 4600 veh/h, respectively. a construction project is planned that will cut the capacity of route 2 by 2100 veh/g. how much additional vehicle-hours of travel time will be added to the system assuming user-equalibrium conditions hold?
