The traffic volume from A to B is 4500 veh/hr. two routes areavailable from A to B. Route I is 6 mi. long, design speed is60mi/hr, link performance function is t1(x)=t1(0)+4x; Route II is 3mi, design speed is 45mi/hr, link performance function ist2(x)=t2(0) +x2(where t(0) is the free-flow travel time, and x istraffic flow on the route in 1000 veh/hr). a. Determine the traveltime and flows using user equilibrium method; b. Determine thetravel time and flows using the system optimization method. Comparethe total vehicle hours obtained from both methods.
