A traffic signal has a 60-second cycle length (Red time + Green time). For the travel direction
of interest, the red and green times are 30 seconds each, the arrival rate is constant at 20
[veh/min] and the saturation flow (i.e., the departure rate) is 1 [veh/sec].
a. Calculate the average delay (for all vehicles) for the travel direction of interest.
b. Assume a work zone on the street downstream of the intersection so that only 25 [veh/min]
(in the direction of interest) can pass. Calculate the average delay caused by the work zone
to a vehicle leaving the intersection. Assume that the queue at the work zone never backs-
up into the intersection.
c. Discuss qualitatively the implications of queue spillback from the work zone on the delay
of the system.

Problem 2: The Douglas fir beam below supports uniform live (WL) and dead loads (WD) as shown
below. Assume the total distributed load is 700 lb/ft.
WD=300#/PT. W₁ = 400#
W₁ = 400#/FT-

L=161
a) Assuming an alllowable deflection of L/360, compute the magnitude of the allowable deflection.
b) Using an 8"x12" timber beam (see Table A1-b on page 567 of your text for properties) compute
the actual deflection. Assume E = 1.6 x 100 psi.
c) Based on your answers for parts a and b, determine if an 8"x12" timber beam is safe for this
application

- Consider, M people (aka pax) who want to travel by car from O to D. They all start working at D at Q (e.g., Q-8am). If a person departs at time t, assume the time needed to go from O to D is given by c(t)=A+Bx(t), where x(t) is the flow of people departing at time t [car/unit of time]. In addition, a is the penalty for being early at work (E(t) is how early the person arrived when departing at time t), and ẞ is the penalty for being late at work (L(t) is how late the person arrived when departing at time t). Assume 0 < a < 1 < ß. Further assume the departure time choice problem under the equilibrium conditions. Prove that the arrival time of people who depart when most of the M people start their trips is equal to Q.arrow_forwardConstruction Methodarrow_forwardConstruction Method Ps. not graded, just a reviewerarrow_forward
