Two routes connect an origin and a destination and the total trips between them is 15,000 veh/hr. Route 1 has a free flow travel time of 4 mintutes and travel time increases by 3 minutes and for each additonal 1000 vehicle in flow, and route 2 has a free flow travel time of "b" minutes and travel time increases by 3 minutes for each additional 500 vehicle in flow. If the user equilibrium flow on route 1 is 9,780 veh/hr, determine:
Free-flow travel time on route 2 (i.e. "b") and Equilibrium travel times.
A rectangular channel of 20 f t width and having n = 0.017 carries flow of 800 f t^3/s. Calculate (a) critical depth (b) the minimum speci c energy (c) the speci c energy when depth of flow is 7 f t. What type of flow exists when the depth is (d) 2 f..

The initial velocity of a 15-lb block is given as mv1=15i+15j (ft/s). A force defined by F=250i-250tj (lb) acts on the particle from time t=0 to time t=0.3 s for a total duration of 0.3 s.
Determine if the bridge would fail under a given load. The truck has two axles and the graph should should begin with 1 axle 7 ft into bridge with the other just reaching the bridge.
Calculate the the oritical oxygen demand (mg/L) of a solution containing 450 mg of glucose(C6H12O6) in 2 liters of distilled water.
A tollbooth is to be added, thus reducing the travel time tocross the bridge. The new cost function is C = 50 + 0.2V. Determinethe volume of traffic that would cross the bridge.
