Total hourly origin destination demand

Two routes connect an origin and a destination. Their performance functions are t₁ = 3 + 1.5(x₁/c₁)2 and t₂ = 5 + 4(x₂/c₂), with t's in minutes and x's and c's being route flows and capacities, respectively.

The origin-destination demand is 6000 vehicles per hour, and c₁ and c₂ are equal to 2000 and 1500 vehicles per hour, respectively. Proposed capacity improvements will increase c₂ by 1000 vehicles per hour.

It is known that the routes are currently in user equilibrium, and it is estimated that each 1-minute reduction in route travel time will attract an additional 500 vehicles per hour (from latent travel demand and mode shifts).

What will the user equilibrium flows and total hourly origin destination demand be after the capacity improvement?
