Assume a car park facility where the arrival rate is 1 customer every minute, and the service
process including pressing the button, taking the card, and waiting for the boom to rise leads
to service rate of μ customer every minute.
a. Assume the arrival and service processes are stochastic. Using any software (Excel, Matlab,
or the one you prefer), plot average delay time (including service time) and average queue
size (including the vehicle currently being served) for all combinations of λ = {1,2,3,..,10}
and p = {0.1,0.3,0.5,0.7,0.9}. Specifically, we ask you to make 2 graphs (one for average
delay and the other for average queue size), where the x-axes contains the different values
for 1, and where you make one curve for each p.
b. Assume the arrival process is stochastic but the service process is deterministic with rate μ.
Using any software (Excel, Matlab, or the one you prefer), plot average delay time (including
service time) and average queue size (including the vehicle…
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.

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_forward
