Two routes connect an origin and an destination, with performance functions t₁ = 5+4 1 where x¡ and c¡ are the flow and capacity for route i, respectively, in thousands of vehicles per hour and t; is the travel time for route / in minutes. The total traffic demand for the two routes is 4000 veh/h. 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/h. How many additional vehicle-hours of travel time will be added to the system assuming user equilibrium conditions hold? 503.5 525.3 77.6 55.3 for route 1 and t = 4+ 5 245.4 X C for route 2, Two routes connect an origin and an destination, with performance functions t₁ = 5+4 1 where x¡ and c¡ are the flow and capacity for route i, respectively, in thousands of vehicles per hour and t; is the travel time for route / in minutes.
