The traffic volume from A to B is 4500 veh/hr. two routes are available from A to B. Route I is 6 mi. long, design speed is 60mi/hr, link performance function is t1(x)=t1(0)+4x; Route II is 3 mi, design speed is 45mi/hr, link performance function is t2(x)=t2(0) +x2(where t(0) is the free-flow travel time, and x is traffic flow on the route in 1000 veh/hr). a. Determine the travel time and flows using user equilibrium method; b. Determine the travel time and flows using the system optimization method. Compare the total vehicle hours obtained from both methods.

There are two routes to get from the student dorms to class - a long route, which is scenic, and a short route, which is not scenic. You want to study whether the route that the students choose to take is independent of the weather (in the context of the table, this will mean whether X and Y are independent), and you generate the accompanying table of probabilities. Rainy (Y=0) Sunny (Y =1) Total Long (X=0) 0.1 0.3 0.4 Short...

A Spherical Capacitor with two concentric shells with radii a and b with a<b. The volume between the shells contains a vacuum and the inner and outer shells hold charges +Q and -Q respectively. 1) Use Gauss law to callculate the displacement field D between the spheres. 2) What is the capacitance of this configuration? 3) If the volume is filled with a dialectric with relaltive permittivity, how does the capacitance change?

There are two traffic lights on a commuter's route to and from work. Let X1 be the number of lights at which the commuter must stop on his way to work, and X2 be the number of lights at which he must stop when returning from work. Suppose that these two variables are independent, each with the pmf given in the accompanying table (so X1, X2 is a random sample of size n = 2). x1 0 1 2 μ...
