2. There are two routes in use between Zones 1 and 2. The volume-delay functions for the two routes are as follows: V1 t1 = 22 + V2 t2 = 15 + 150 250 where t = travel time (minutes) V = traffic volume If the total traffic volume is 6,950 vehicles per hour between the two zones, what are the traffic volumes and travel times on each of the two routes at a user-equilibrium (UE) condition?

2. There are two routes in use between Zones 1 and 2. The volume-delay functions for the two routes
are as follows:
V1
V2
t1 = 22 +
250
t2 = 15 +
150
where
t = travel time(minutes)
V = traffic volume
If the total traffic volume is 6,950 vehicles per hour between the two zones, what are the traffic
volumes and travel times on each of the two routes at a user-equilibrium (UE) condition?
